Chapter 3 High Availability Networkin g High availability networking is achieve d by eliminating any single point of failure through redundant connectivity: Redundant cable s, switches and network interfaces for hardware, combined with HA software solutions on both the hos ts and switches to control the HA hardware and maintain connectivity.
VRRP Since most end nodes use default router addres ses, the change of the default router address during a switch failover would require the end nodes to reconfigure. Layer 3 switches that failover must maintain the default router address to ma intain the end node's IP transparent failover.
Switch Replacement and Reconf iguration When a switch fails, it must be repl aced. The replacement switch will likely requi re proper configuration. For transparent switch replac ement, the newly replaced switch must le arn its configuration from its Surviving Partner.
The configuration and runtime scripts creat ed are as follows: • S70Surviving_partner Switch initialization script that is run at boot time. This script will restart the switc h with the original configuration given to zspconfig . Optionally, zspconfig will run this script from the i nitial invocation.
When using a Linux Bonding driver on the node card, the bonding dri ver should be configured for Mode 1 (active/standby). See the Linux Bonding docum entation at http://sourceforge.
sibling_addresses: zhp1 = 10.0.0.30, 10.0.0.31 netmask 255.0.0.0; Now configure the virtual address for each s ibling group. We are going to create a virtual interface across one VLAN, but not for the inte rconnect. This provides a single point to connect/route to the VLANs.
#vrrp_mode: block_crossconnect; The next sections determines t he failover mode between the Surviving Partner switches. Ther e are three modes: • switch - Failover by switch. Failover from Maste r switch to Backup on any port failure. The switch with the most links becomes the new Master.
#start_script:/etc/rcZ.d/SxxScript; #start_script:/etc/rcZ.d/SyyScript; # vrrpd_script: Allows the user to add scripts to be executed during # vrrpd state transitions. These scripts are run from the end of the # /etc/rcZ.d/surviving_partner/vrrpd.script file.
Once the configuration files are comple te, run the zspconfig utility on the Master to configure all the scripts: NOTE: This command can take 60 seconds or more with n o screen output. zspconfig –f zsp.conf You will see output similar to this: zspconfig -f zsp.
# This script will likely need modification for your particular # network setup. # # In this example the Egress ports, zre20..23 and zre48..50 are # not managed by HA since how, or if, these ports are managed by HA is # dependent on the external devices they are connected to.
zconfig zre0, zre4, zre8, zre12, zre16, zre24, zre28, zre30, zre32, zre34, zre36, zre38, zre40, zre42 = untag1; zconfig zre1, zre5, zre9, zre13, zre17, zre25, zre29, zre31, zre33, zre35, zre37, zre39,.
vrrp_virtual_address: zhp1 = 10.0.0.42 netmask 255.0.0.0; vrrp_virtual_address: zhp2 = 11.0.0.42 netmask 255.0.0.0; vrrp_virtual_address: zhp3 = 12.0.0.42 netmask 255.0.0.0; vrrp_virtual_address: zhp4 = 13.0.0.42 netmask 255.0.0.0; # Port definitions # Define to what the ports are connected.
# crossconnect ports of the VRRP Backup. The block_crossconnect mode is # meant as a replacement for STP, however, the switches connected to the # crossconnect ports must be Ethernet Switch switches running Surviving Partner.
failover_mode: port; # VRRP_msg_rate is the time in milliseconds between transmissions # VRRP messages on the interconnect. The VRRP protocol requires the # absence of 3 VRRP messages before concluding that the remote switch # has failed. The msg_rate must match the msg_rate of all siblings.
# Fabric portions of the 7100 switch. The actual coordination is dependent on the # setting of the board_synchronization_mode and the failover_mode. In # switch failover_mode the number of up links in both switch planes is # considered. In vlan and port failover mode they are not.
# gated_template: Allows the user to provide a template for the # gated.conf file to be used by the sibling group. #gated_template: /etc/rcZ.d/surviving_partner/gated.
Finally, it lets the currently saved S70Surviving_Partner script execute. This case would be the case of a power up of an already configured backup sw itch when the other HA switch is unavailable. This case could occur after losing power to the entire chassis.
"zsp.primary.conf"; } host SECONDARY { fixed-address 100.0.0.31; option dhcp-client-identifier "SECONDARY"; option vendor-encapsulated-options "zsp.secondary.conf"; } } The zsp.primary.conf and zsp.secondary.conf files must be placed in the tftp location on the machine, often /tftpboot .
request vendor-encapsulated-options; require vendor-encapsulated-options; The last step is to modify the start up scripts that run zspconfig to use the -c option. The -c option allows you to provide a dhclient.conf script rather then having zspconfig create a default.
Chapter 4 Fabric Switch Configu ration Two switches, two consoles There are two separate switch port ions in the Ethernet Switch Blade units, the base s witch and the fabric switch. The fabric switch handles the data traffic for the ATCA rack over ports 0-47.
Changing the Shell Prompt You may use standard bash shell procedures to change the prompts on your base switches. Many sites choose a system that distingui shes among the individual switches at their locati on. The same rules apply for saving your choice ( zsync) a s for all other configuration changes.
Overview of OpenArchitect VLAN In terfaces A zhp device is associated with one VLAN. zhp ma y have one or more physical ports and their associated zre devices. A VLAN from the viewpoint of the switch is a logical mapping of ports based on intended use.
Switch Port Interfaces For each switch port, OpenArchitect c reates a separate interface with its own MAC a ddress called a ZNYX raw Ethernet ( zre ). After the initial power up, 48 zre interfaces are created, one for each in band port. You cannot directly acce ss or modify the zre interfaces.
ifconfig zhp1 0.0.0.0 # # At this point the system will act as a Layer 2 switch # across all ports. Also, the system will accept telnet() # connections on 10.0.0.43 on any port. Script(s) may then # be run to reinitialize the system and modify its # configuration.
To Enable Rapid Spanning Tree: Create a VLAN containing the ports that will be a part of the Linux bridge running Rapid Spanning Tree. This example will use ports 0-3 (unta gged): zconfig zhp0: vlan1=zre0.
Layer 3 Switch Configuration The previous section outlines the Layer 2 switch configuration that is automatically confi gured when you initially bring up the OpenArchitec t switch. In order to communicate between Layer2 interfaces, you must properly setup routing.
In the S50layer3 script separate VLANs are set up for ea ch port. The VLANs, are labeled as zhp0..zhpn . Each VLAN is associated with an individua l zre interface.

Marking and Re-marking The OpenArchitect switch can mark or rem ark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utili ty. Scheduling The servicing of configured queues by the switc hing fabric is referred to as scheduling.
you may want to move your set of iptables commands t o a start up script to run upon initialization. This could be a ccomplished by creating a standalone " S " script and plac ing that script into / etc/rcZ.d . Restrictions on Implementation Several restrictions exist on the r ules that can be implemented on the FFP hardware.
On the other hand, in the following sequence of rule s, the position of the rule that drops SYN packets is important. Since the set of fi elds it examines is not a subset of the fields exa mined by the ACCEPT rules, and visa versa, the order ing rule given above does not apply.
By default, INPUT, FORWARD and OUTPUT chains are insta lled on boot up. Additional rules can be installed for the other chains . Additionally, one can write software extensions to add mor e chains. Figure 4.2 provides an illustration of the Firewall Flow.
send to CPU action is specified, it is sent to the INPUT chain for further processing. If there is no valid way to forward the packet, it is dropped. If t he switch is configured to forward the packet, it is sent to the FORWARD chain. Next the hardware FORWARD chain is walked.
The type can be preceded by ! to match a ny message except the type listed, for example, -- icmp-type ! 1 Specifying TCP or UDP po rts If the protocol is TCP or UDP, the -s ( or --sport ) and -d (or --dport ) opti ons specify the TCP or UDP ports to match.
--drop Drops the packet --accept Accepts the packet --set-prio <val> Set the 802.1p priority to <val> --use-prio <val> Use queue priority <val> --copy-cpu Send the packet to the CPU.
FORWARDING Chain supports all of them. tc and zqosd tc , which stands for Traffic Control, is a mec hanism for enabling Quality of Service on Linux. tc uses three functional objects: queuing dis cipli.
qdisc pfifo 100: dev zhp0 limit 32p The tc command is applied to a device, so dev zhp0 must be specified. Note that a VLAN, such as zhp0 , and a port, such as zre0 , are eac h treated as devices. Breakdown of the options: handle 100:0 Defines the handle for the queuing discipl ine.
The byte-limited FIFO queue case differs only s lightly from the packet-limited FIFO case. T he syntax is almost identical. In hardware the limit is based on 128-byte cells. The speci fied byte limit is divided by 128 to determine the cel l limit. Always specify a byte limit of at least 128 bytes to avoid setting the queue length to zer o.
index of the list element (numbering f rom 0) and q is the value specified by that element. So, thi s example would read: Priority 0 maps to Queue 1 Priority 1 maps to Queue 2 Priority 2 maps to Queue 2 Priority 3 maps to Queue 2 Priority 4 maps to Queue 3 Note that the tc priority map applies to a 4- bit field.
The U32 Filter The U32 filter provides the capability to mat ch on fields in the L2, L3 or L4 header of a packet. Each match rule gives the locati on of the field to be tested, which is always a 32 bit word, a mas k selecting the bits to be test ed, and a value which is to be matched by the packet field.
Although the translation rules handle some inconsistency between software and hardware, a use r must define a combination of rules that is reasonable in hardware, to ensure predictable re sults. Handle Semantics All examples have illustrate d zqosd copying tc rules into hardware.
• The PDP sends that policy to the PEP. • The PEP installs the policy and applie s it to future traffic. As long as COPS is running, a connection between the P EP and PDP should stay open. A PEP could query a PDP at any time asking for a policy deci sion.
The pepd utility requires a PDP that has impl emented the above RFCs and drafts. Until all dra ft standards are approved, the certain COPS-PR data types will not be assigned OIDs.
Chapter 5 Fabric Switch Administration One of the main benefits of the OpenArchite ct switch is that it runs Linux, so much of the switch administration is already familiar to most network or system administrators.
Enter new password: Re-enter new password: Password changed. ZX7100-OA<release no.># zsync ZX7100-OA<release no.># Setting up a Default Route If you wish to access the switch from some pla ce other than a directly attached network, you may want to setup a default route.
dhcpd Consult Linux Network administration m anuals for more information on DHCP and configuration options. To use DHCP to set your IP addresses automatical ly on boot up, uncomment the the following line in /etc/init.
/sbin/rpc.statd /usr/sbin/rpc.mountd -r Once the above servers are started, you c an mount a remote NFS file system. mount rhost:nfs_file_system local_mount_point If the remote NFS file system you’re mounting is on an OA switch, you should mount with caching disabled.
Now start nfsd to export the mount points and begin answer ing requests from remote clients. /sbin/rpc.nfsd –r To export file systems automatic ally on boot, edit /etc/init.d/rcS , uncomment the /sbin/rpc.nfsd command line by removing the #. /sbin/rpc.
SNMP Agent Simple Network Management Protocol (SNMP) is the defacto standard for network management. An SNMP agent maintains a structure of data for a network device in a virtual information database, called a Management Inf ormation Base (MIB).
Supported MIBs RFC 2573: S NMP Applications RFC 2574: U ser-based Security Model (USM) for version 3 of the Simple Network Management Protocol (SNMPv3) RFC 2575: V iew-based Security Model (VACM) for .

This mirroring would be in addition to any Layer 3 or Layer 2 switching. zmirror zre0 zre12 zmirror zre1 zre12 zmirror zre2 zre12 To clear the current mirroring use the -t option. The -e option can be used to indicate that packets being sent on a given port should be copi ed to the mirror_to port.
Chapter 6 Fabric Switch Maintenance This chapter includes basic informa tion about the OpenArchitect switch environment incl uding an overview of the file system structure, modi fying and updating switch files, upgrading the switch driver and kernel, and implementing a s ystem recovery.
Figure 6.2: Boot Flow Chart Under normal circumstances, the booting up proc ess follows the process outlined in Figure 6.2. During boot up, the zmon bootloader reads the device boot string to locate and validate the correct application image to l oad.
Saving Changes Any modifications made to the scripts for your particular configuration must be properly saved or your changes are lost when you reboot. The file syste m for the switch only exists in memory. A rewritable overlay is contained within t he upper four megabytes of the first application f lash.
configuration files contained in / e t c / r c Z . d In order to telnet into the box, there must be a configured interface with a proper IP address. For e xample, zhp0 is configured with the IP address 10.
zsync /etc/hosts • Reboot the system. System Hangs During Boot After attaching the system console cabl e, if the system hangs during boot, try booting with the –i option as described in the previous section. It is possible that important Linux system fil es became corrupted and incorrectly save d in the flash overlay.
Download the OpenArchitect image to a local system. The OpenArchitect image is very cl ose to the limit of free space available on a default system so you may need to clear some space prior to downloadi ng the OpenArchitect image to the switch. Check for free space with the df c ommand.
Using apt-get apt-get is a utility created by the Debia n Linux community to allow remote fetching and installation of software stored in a repository in Debian package format. It allows users to keep their software up-to-date with the latest binaries, and install new software without the need to recompile.
Chapter 7 Base Switch Configuration At this point, the OpenArchitect Ether net Switch Blade should be installed and powered up for the first time. This chapter helps you conne ct and configure the base switch by presenting command line examples as well as a disc ussion of the example configuration scripts .
files into flash for reloading. Changing the Shell Prompt You may use standard bash shell procedures to change the prompts on your base switches. Many sites choose a system that distingui shes among the individual switches at their locati on. The same rules apply for saving your choice ( zsync ) as for al l other configuration changes.
• S50multivlan - Script which sets up multiple untagged VLANs. The first VLAN includes the first ten 10/100/1000 ports, the next contains the last ten 10/100/1000 ports, the third VLAN contains two 10/100/1000 ports, the last VLAN contains the last two 10/100/1000 ports.
Tagging and Untagging VLANs The OpenArchitect switch is capabl e of switching VLAN tagged and untagged data packets. VLAN tagged packets conform to the 802.1q specific ation and the packet header contains an additional four bytes of VLAN tag information.
Figure 7.2: Layer 2 Switch During the initial power up, a startup script called /etc/rcZ.d/S50layer2 is executed at boot time creating a single untagged VLA N (IP interface labeled as zhp0 ) which includes all Ethernet and gigabit ports as one Layer2 switch.
Using the S50layer2 Script The S50layer2 script can be used and example, or edited to customiz e your Layer2 setup. For example, to reconfigure the IP address on your Layer 2 switch , • Open the S50Layer2 file in the Linux vi editor. • Change the IP address value listed under the Linux ifconfig(1M) command line.
brctl show brctl showbr bzhp0 Port Path Cost Each port has an associated cost that c ontributes to the total cost of the path to the Root Bridge when the port is the root port. The smaller the cost, the better the path. The Ethernet Switch Blade uses the following IEEE 802.
zconfig zhp1: vlan2=zre5..8 zconfig zre5..8=untag2 Now, use ifconfig to assign each zhp interface an IP address, ifconfig zhp0 10.0.0.1 ifconfig zhp1 11.0.0.1 At this point, the Linux host has enough informati on to route between the networks of the directly attached interfaces, 10.

• Runs the OpenArchitect zl3d . The zl3d application monitors the Linux routing tables and updates the switch routing tables for each inte rface configured above. /usr/sbin/zl3d zhp0..23 zl3d initially creates and adds eac h zhp interface (VLAN) to the switch routing tables.
• VLAN 4, zhp3: for last set of six ports, zre18- zre23 Each VLAN interface is labeled z h p N in the file, where N is a value from 0-3. Each interface is untagged and assigned its own IP address (see Figure 7.

Marking and Re-marking The OpenArchitect switch can mark or rem ark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utili ty. Scheduling The servicing of configured queues by the switc hing fabric is referred to as scheduling.
Running zfilterd Before starting zfilterd , ztmd must be running. Your can star t both from within a script, or directly from the command line . For example, ztmd zfilterd iptables rules can be entered at any time.
action that will take place . For example, the rules: iptables -a FORWARD -i zhp3 -j DROP iptables -a FORWARD -i zhp3 -o zhp1 -p tcp --dport smtp -j ACCEPT result in SMTP packets received on any port in zhp3 to be sent for any port in zhp1 ; all other packets from zhp3 would be dropped.
Introduction Firewall rules are stored in tables. The se tables are sometimes also known as firewal l chains or just chains . Tables normally store rules for what are known as hooks , which can be looked as packet-path junctions. There are five de fined hooks: PRE-ROUTE, POST-ROUTE, INPUT, OUTPUT and FORWARDING.
Packet Walk When a packet comes in via one of the int erface ports, the base switch makes a routi ng decision. If the packet was destined for the base switch itself or if the send to CPU action is speci fied, it is sent to the INPUT chain for further processing.
--icmp-type ping The type can be preceded by ! to match a ny message except the type listed, for example: --icmp-type ! 1 Specifying TCP or UDP po rts If the protocol is TCP or UDP, the -s ( or --sport ) and -d (or --dport ) opti ons specify the TCP or UDP ports to match.
ZNYX Targets ZACTION This is the ZNYX Action target. Parameters for ZACTION: --drop Drops the packet --accept Accepts the packet --set-prio <val> Set the 802.1p priority to <val> --use-prio <val> Use queue priority <val> --copy-cpu Send the packet to the CPU.
Extensions to the default matches These are described in the Linux packet filtering HOWTO at: http://netfilter.org/docume ntation/index.html#documentation-howto ZNYX FORWARDING Chain supports all of them. tc : Traffic Control The switch supports up to eight queues for each por t, including the cpu port.
queue number + 1 after the qdisc handle. So the highest priority queue in this example is 105:8. NOTE: 16 values must be provided for the priomap list. T his is a feature of the Linux priority system, which uses 16 priority level s. The last eight values given will be ignored.
handle 100:0 Defines the handle for the queuing discipl ine. This handle may be used to reference the pfifo queue. Note that the ha ndle is included with the output of the qdisc ls command. (100:0 and 100: are equi valent in tc .) The choice of handle is significant for zqosd .
match ip tos 0xa0 0xe0 would match an IP precedence of 5. Specific fields can also be speci fied by giving their offset from the beginning of the IP hea der and a field name of u8 , u16 , or u32 , depending on the width of the fiel d.
tc qdisc add dev zre1 ingress //ingress qdisc for zre1 tc qdisc add dev zhp2 ingress //ingress qdisc for vlan The filter add command changes slightly, the pa rent is now a special handle ffff:fff1, so using the same filter as the first example : tc filter add dev zre1 parent ffff:fff1 protocol ip u32 match ip dst 10.
omitted, and the packet is not dropped, the e gress queue will be determined by the priority of t he packet, either from the 802.1p priority for ta gged packets or the default priority for untagged packets for the ingress port.

OpenArchitect switch though, because the norm al case is for packets to be switched in hardware. For that reason, zqosd must be used to shadow tc configurati on into hardware. Like zfilterd , zqosd works with ztmd , which provides the actual hardwar e interaction.
In tc , the prio queuing discipline establishes multi ple queues and specifies their associate d priority map. Although WRR support is not part of the standard tc distribution, it has been added to the prio disciplinE. The following example illustrat es WRR.

Network Time Protocol ( NTP) Client Configuration NTP is a protocol for setting the real time clock on a system. There are numerous primary and secondary servers available on the network. F or more NTP information, and a list of available NTP servers, see the following URL: http://www.
All the necessary servers are included in /etc/init.d/rcS but are commented out by default. To automatically start all NFS client services each time you boot, uncomment t he NFS Client servers. Go to the /etc/init.d/rcS file. Uncomment the following command lines by removing the # sign.
ftpd Server Configuration The switch itself can also be configured to run a n FTP server ( ftpd ). See the Linux Reference Guide for details of the ftpd command. You will ne ed to add a user to the switch in order to connect via ftp from a remote host, since root is not allowed ftp access.

Under normal circumstances, the booting up proc ess follows the process outlined in Figure 6-2. During boot up, the zmon bootloader reads the device boot string to locate and validate the correct application image to l oad.
Saving Changes Any modifications made to the scripts for your particular configuration must be properly saved or your changes are lost when you reboot. The file syste m for the switch only exists in memory. A rewritable overlay is contained within t he upper four megabytes of the first application f lash.
Booting with the –i option If you cannot telnet into the switch and Linux fails to boot, it is likely that a change saved by zsync has left the switch in an inaccessible state.
