Conguring SNMP
Configuring SNMP
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). Notications are traps, which are not acknowledged by
the notication target (also called a trap receiver).
• SNMPv2c - SNMPv2 is similar to SNMPv1, but supports informs. An inform
is a notication that is acknowledged by the notication target.
• SNMPv3 - SNMPv3 adds authentication and encryption options. Instead of
community strings, SNMPv3 supports user security model (USM) users, with
individually congurable access levels, authentication options, and
encryption options.
All SNMP versions are disabled by default.
Conguring SNMP
To congure SNMP, perform the following tasks:
• Set the switch’s system IP address, if it is not already set. SNMP will not work with
out the system IP address.
• 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.
• Congure community strings (for SNMPv1 or SNMPv2c) or USM users
(forSNMPv3).
• Set the minimum level of security allowed for SNMP message exchanges.
• Congure a notication prole or modify the default one, to enable sending of notications
to notication targets. By default, notications of all types are dropped (not sent).
• Congure notication targets.
• Enable the MSS SNMP engine.
