Simple Network Management Protocol (SNMP) is supported on plat<strong>for</strong>ms c e s<br />

Simple Network Management Protocol (SNMP) is used to communicate management in<strong>for</strong>mation<br />

between <strong>the</strong> network management stations and <strong>the</strong> agents in <strong>the</strong> network elements. <strong>FTOS</strong> supports SNMP<br />

versions 1, 2c, and 3, supporting both read-only and read-write modes. <strong>FTOS</strong> sends SNMP traps, which<br />

are messages in<strong>for</strong>ming <strong>the</strong> SNMP manager about <strong>the</strong> network. Up to 16 SNMP trap receivers are<br />

supported.<br />

<strong>FTOS</strong>’s SNMP implementation con<strong>for</strong>ms to RFC 1157 and RFC 2274 and <strong>the</strong> enterprise-specific MIB<br />

<strong>Force10</strong>-COPY-CONFIG-MIB, which supports SNMP SET requests.<br />

Important Points to Remember<br />

• Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient <strong>for</strong> both LAN<br />

and WAN applications. If you experience a timeout with <strong>the</strong>se values, <strong>Force10</strong> recommended best<br />

practice is to increase <strong>the</strong> timeout and retry values on your SNMP server to <strong>the</strong> following to<br />

accommodate <strong>the</strong> high port density provided by <strong>the</strong> <strong>Force10</strong> system:<br />

SNMP Timeout—greater than 3 seconds<br />

SNMP Retry count—greater than 2 seconds<br />

• If you want to query <strong>the</strong> chassis using SNMP v1/v2/v3 with an IPv6 address, configure <strong>the</strong> IPv6<br />

address on an non-management port on <strong>the</strong> chassis.<br />

• If you want to send SNMP v1/v2/v3 traps from <strong>the</strong> chassis using an IPv6 address, use a<br />

non-management port.<br />

• SNMP v3 in<strong>for</strong>ms are not currently supported with IPv6 addresses.<br />

• If you are using ACLs in SNMP v3 configuration, group ACL overrides user ACL if <strong>the</strong> user is part of<br />

that group.<br />

<strong>Configuration</strong> Task List <strong>for</strong> SNMP<br />

To enable SNMP on <strong>the</strong> system, enter <strong>the</strong> snmp-server community command. A system message appears<br />

after you enable SNMP. The following list contains configuration tasks <strong>for</strong> SNMP:<br />

• configure access to an SNMP community on page 90 (mandatory)<br />

• configure <strong>the</strong> system to send SNMP notifications on page 90 (mandatory)<br />

• set SNMP in<strong>for</strong>mation on page 93 (optional)<br />
