source IP addr ess range (Sourc e IP Address AND Sour ce Subnet Mask), and destination IP address r ange (Destination IP Addr ess AND Destination Subnet Mask). A source (destina tion) IP address range is determined b y per forming an AND operation on the source (destina tion) IP address field and the sour ce (destination) subnet mask field .
3.6.2.3. Syst em Log Fi g. 53. System log settings. Sy stem events can be logged t o the on-board RAM of the SMC2582W-B (Local log) or sent in the form of SNMP trap (Remote log by SNMP trap) or BSD Sy slog (Remote log by BSD Syslog) to a remote SNMP tr ap monitoring server or remote Syslog server , respectively .
To s p e c i f y a trap target: 1. T ype the IP address of the target host. 2. T ype the Co m m u n i ty for the host. 3. S elect the corresponding check box next to the IP addr ess text box.
Appendix A: Default S ettings TIP: Pr ess the Default switch on the housing of a pow ered-on SMC2582W-B t o reset the configuration settings t o factor y-default values.
Appendix B: T roubleshooting Check the following first: • Mak e sure that the pow er of the SMC2582W-B is on and the Ethernet cables ar e connected firmly to the RJ-45 jacks of the SMC2582W-B . • Mak e sure that the LED AL V of the SMC2582W-B is blinking to indica te the SMC2582W-B is wor kin g.
For a w ire le ss client computer to communica te with a corr espondent host on the Internet by the host’ s domain name (e.g. http://www .wi-fi.com), it first sends a DNS request to a DNS server on the Internet. The DNS request trav els first to the AP , then the AP relays this request to the default ga te- way of the client computer .
• So l v e the preceding pr oblem first. • Ar e the IP address of the SMC2582W-B and the IP addr ess of the client computer in the same IP subnet? • If y ou cannot find any incorr ect settings of the SMC2582W-B, the default gatew ay may be rea ll y d own or there are other communica tion problems on the network backbone .
• My SMC2582W-B stops working and does not respond t o W eb management requests. • The firmwar e of the SMC2582W-B may be stuck in an incorr ect state. • Unplug the power c onnector from the power jack, and then re-plug the connector to re star t the SMC2582W-B.
