There is no specific command that you use to enable SNMP. To configure SNMP support, perform the tasks described in the following steps, only the first two steps are mandatory:

1.Enable the SNMP community string to define the relationship between the network
management station and the agent with the following command:

snmp−server community {ro|rw} {number}

The number value references an optional access−list.

2.Use this command to configure the router to send traps to an NMS host:

snmp−server host host [version {1|2c}]


3.Configure the type of traps for which a notification is sent to the NMS. You do so with the following command:

snmp−server enable traps [notification type] –
[notification option]

4.Set the system contact, location, and serial number. You can set the systems contact with the snmp−server contact [text] command. You set the location with the snmp−server location [text] command, and you set the serial number with the snmp−server chassis−id [text] command.

5.Use the access−list command to specify a list of hosts that are allowed read−, read/write, or write−only access to the router.

The picture below: shows Router 1, which is configured to allow SNMP read−only access and read/write access from two separate hosts. Router 1 is also configured to send SNMP trap information to the same two hosts. The following lines show how Router 1 should be configured so SNMP access from both host 192.168.10.1 and 192.168.10.2 is allowed and SNMP trap information is sent to both hosts:

access−list 12 permit 192.168.10.1
access−list 13 permit 192.168.10.2
snmp−server contact VISA
snmp−server location Network Engineers
snmp−server chassis−id 200000444
snmp−server community observe RO 12
snmp−server community adjust RW 13
snmp−server host 192.168.10.1 observe snmp
snmp−server host 192.168.10.2 adjust snmp

Router 1 configured for SNMP
