Conﬁguring 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). 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.

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 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.

• Conﬁgure community strings (for SNMPv1 or SNMPv2c) or USM users

(forSNMPv3).

• 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 MSS SNMP engine.
