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