155Nortel WLAN Security Switch 2300 Series Configuration GuideConfiguring SNMPWSS Software supports Simple Network Management Protocol (SNMP) versions 1, 2c, and 3.OverviewThe WSS Software SNMP engine (also called the SNMP server or agent) can run any combination of the followingSNMP versions:• SNMPv1—SNMPv1 is the simplest and least secure SNMP version. Community strings are used forauthentication. Communications are in the clear (not encrypted). Notifications are traps, which are notacknowledged by the notification target (also called a trap receiver).• SNMPv2c—SNMPv2 is similar to SNMPv1, but supports informs. An inform is a notification that isacknowledged by the notification target.• SNMPv3—SNMPv3 adds authentication and encryption options. Instead of community strings, SNMPv3 supportsuser security model (USM) users, with individually configurable access levels, authentication options, andencryption options.All SNMP versions are disabled by default.Configuring SNMPTo configure SNMP, perform the following tasks:• Set the switch’s system IP address, if it is not already set. SNMP will not work without the system IP address. (See“Configuring the System IP Address” on page 114.)• Optionally, set the system location and contact strings.• Enable the SNMP version(s) you want to use. WSS Software can run one or more versions, in any combination.• Configure community strings (for SNMPv1 or SNMPv2c) or USM users (for SNMPv3).• Set the minimum level of security allowed for SNMP message exchanges.• Configure a notification profile or modify the default one, to enable sending of notifications to notification targets.By default, notifications of all types are dropped (not sent).• Configure notification targets.• Enable the WSS Software SNMP engine.Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 155Configuring SNMP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 155Displaying SNMP Information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 167
