Chapter 72 Configuring SNMP
Configuring SNMP
Configuring SNMP Notifications
A trap manager is a management station that receives and processes traps. Traps are system alerts that
the switch generates when certain events occur. By default, no trap manager is defined, and no traps are
sent. Switches running Cisco IOS Release 12.2(31)SG and later releases can have an unlimited number
of trap managers.
Note Many commands use the word traps in the command syntax. Unless there is an option in the command
to select either traps or informs, the keyword traps refers to either traps, informs, or both. Use the
snmp-server host command to specify whether to send SNMP notifications as traps or informs.
Table 72-3 describes the supported switch traps (notification types). You can enable any or all of these
traps and configure a trap manager to receive them.
Step 4
Switch(config)# snmp-server user
username groupname [remote host
[udp-port port]]
{v1 | v2c | v3 [auth
{
md5 | sha} auth-password]} [encrypted]
[access access-list]
Configures a new user to an SNMP group.
• The username is your name on the host that connects to the agent.
• The groupname is the name of the group to which you are
associated.
• (Optional) Enter remote to specify a remote SNMP entity to
which you belong and the hostname or IP address of that entity
with the optional UDP port number. The default is 162.
• Enter the SNMP version number (v1,or v2c, or v3). If you enter
v3, you have these additional options:
–
auth is an authentication level setting session, which can be
either the HMAC-MD5-96 or the HMAC-SHA-96
authentication level, and requires a password string (not to
exceed 64 characters).
–
encrypted specifies that the password appears in encrypted
format.
• (Optional) Enter access access-list with a string (not to exceed 64
characters) that is the name of the access list.
Step 5
Switch(config)# end
Returns to privileged EXEC mode.
Step 6
Switch# show running-config
Verifies your entries.
Step 7
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
