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.

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
auth-password
(not to exceed 64 characters).
•
If you enter
v3
and the switch is running the cryptographic
software image, you can also configure a private (
priv
)
encryption algorithm and password string
priv-password
(not
to exceed 64 characters).
–
priv
specifies the User-based Security Model (USM).
–
des
specifies the use of the 56-bit DES algorithm.
–
3des
specifies the use of the 168-bit DES algorithm.
–
aes
specifies the use of the DES algorithm. You must
select either 128-bit, 192-bit, or 256-bit encryption.
•
(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.
Note
To display SNMPv3 information about

priv
mode configuration, you must enter the
show snmp
user
privileted command.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
