Enabling SNMP Communities
To configure SNMP, you need to enable SNMP on your switch.
Then you can enable authentication failure traps. However, this is
an optional step.
Traps generated by the SNMP agent are forwarded to all trap
receivers in all of the SNMP communities. (For information about
configuring the trap host receiver IP addresses and the SNMP
management stations, see Configuring SNMP Communities on
page 71.) The SNMP community name and manager IP addresses
are used to provide authentication. An incoming SNMP message
is deemed authentic if it contains a valid community name and it
originated from an IP address that is defined as a management
station for that community.
When a community is disabled, the SNMP agent behaves as if the
community does not exist. In addition, the switch generates
authentication failure traps for messages directed to the disabled
community.
SNMP authentication is a mechanism where an SNMP message is
declared to be authentic. The authentication failure trap may be
generated as a result of the failure to authenticate an SNMP
message. See the procedure below for instructions on how to
enable or disable the generation of authentication failure traps.
To enable SNMP and authentication trap messages, perform the
following procedure.
1. From the Main Menu, type 5 to select System Menu.
The System Menu is shown in Figure 5 on page 47.
2. From the System Menu, type 1 to select Configure System.
The Configure System menu is shown Figure 9 on page 52.
3. From the Configure System Menu, type 1 to select Configure System
Software.
The Configure System Software Menu is shown in Figure 10 on
page 53.
