Chapter 29 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 this Cisco IOS release 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 global configuration command to specify whether to send SNMP notifications as
traps or informs.
Table 29-5 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 snmp-server user username groupname
{remote host [udp-port port]} {v1 [access
access-list] | v2c [access access-list] | v3
[encrypted] [access access-list] [auth
{md5 | sha} auth-password]}
Add a new user for an SNMP group.
• The username is the name of the user on the host that connects to
the agent.
• The groupname is the name of the group to which the user is
associated.
• Enter remote to specify a remote SNMP entity to which the user
belongs 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, v2c, or v3). If you enter v3,
you have these additional options:
–
encrypted specifies that the password appears in encrypted
format. This keyword is available only when the v3 keyword
is specified.
–
auth is an authentication level setting session that can be
either the HMAC-MD5-96 (md5) or the HMAC-SHA-96
(sha) authentication level and requires a password string (not
to exceed 64 characters).
• (Optional) Enter access access-list with a string (not to exceed 64
characters) that is the name of the access list.
Step 5 end Return to privileged EXEC mode.
Step 6 show running-config Verify your entries.
Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file.
