Step 6
Router(config)# snmp-server enable
traps ipran
Example:
Router(config)# snmp-server enable
traps ipran
Enables SNMP trap messages for all IP-RAN notifications.
Note Besides enabling SNMP trap messages for all IP-RAN
notifications, you can also enable the messages for IP-RAN GSM
alarms, UMTS alarms, and general information about the
backhaul utilization.
Step 7
Router(config)# snmp-server enable
traps envmon
Example:
Router(config)# snmp-server enable
traps envmon
Enables SNMP trap messages for a specific environment.
Step 8
Router(config)# snmp-server host
host-address
[traps | informs]
[version {1 | 2c | 3 [auth | noauth
| priv]}]
community-string
[udp-port
port
] [
notification-type
]
Example:
Router(config)# snmp-server host
10.20.30.40 version 2c
Specifies the recipient of an SNMP trap messages. To remove the
specified host, use the no form of this command.
• host-address—Name or Internet address of the host (the targeted
recipient).
• traps—Sends SNMP trap messages to this host. This is the default.
• informs—(Optional) Sends SNMP informs to this host.
• version—(Optional) Version of the SNMP used to send the traps.
Version 3 is the most secure model because allows packet encryption
with the priv keyword. If you use the version keyword, one of the
following must be specified:
–
1—SNMP version 1. This option is not available with informs.
–
2c—SNMP version 2C.
–
3—SNMP version 3. The following three optional keywords can
follow the version 3 keyword:
–auth (Optional). Enables Message Digest 5 (MD5) and Secure
Hash Algorithm (SHA) packet authentication
–noauth (Default). The no authentication-no privileges security
level is the default if the auth | noauth | priv] keyword choice is
not specified.
–priv (Optional). Enables Data Encryption Standard (DES)
packet encryption.
• community-string—Password-like community string sent with the
notification operation. Though you can set this string using the
snmp-server host command by itself, we recommend you define this
string using the snmp-server community command before using the
snmp-server host command.
• udp-port port—UDP port of the host. The default value is 162.
