MSS supports Simple Network Management Protocol (SNMP) versions 1, 
2c, and 3.

The MSS SNMP engine (also called the SNMP server or agent) can run any 
combination of the following SNMP versions:

„

SNMPv1—SNMPv1 is the simplest and least secure SNMP version. 
Community strings are used for authentication. Communications are 
in the clear (not encrypted). Notifications are traps, which are not 
acknowledged by the notification target (also called a trap receiver).

„

SNMPv2c—SNMPv2 is similar to SNMPv1, but supports informs. An 
inform is a notification that is acknowledged by the notification 
target.

„

SNMPv3—SNMPv3 adds authentication and encryption options. 
Instead of community strings, SNMPv3 supports user security model 
(USM) users, with individually configurable access levels, 
authentication options, and encryption options.

All SNMP versions are disabled by default.

To 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 108.)

„

Optionally, set the system location and contact strings.

„

Enable the SNMP version(s) you want to use. MSS can run one or 
more versions, in any combination. 

„

Configure community strings (for SNMPv1 or SNMPv2c) or USM users 
(for SNMPv3).
