Chapter 1: Accessing the Switch

2.Configure a user access group, along with the views the group may access. Use the access table to configure the group’s access level. Because the read view, write view, and notify view are all set to iso, the user type has access to all private and public MIBs.

ex2500(config)# snmp-server access 5 name admingrp ex2500(config)# snmp-server access 5 level authpriv ex2500(config)# snmp-server access 5 read-view iso ex2500(config)# snmp-server access 5 write-view iso ex2500(config)# snmp-server access 5 notify-view iso

3.Assign the user to the user group. Use the group table to link the user to a particular access group.

ex2500(config)# snmp-server group 5 user-name admin ex2500(config)# snmp-server group 5 group-name admingrp

Configuring SNMP Trap Hosts

SNMPv1 Trap Host Configuration

1.Configure an entry in the notify table.

ex2500(config)# snmp-server notify 10 name public ex2500(config)# snmp-server notify 10 tag v1trap

2.Specify the IP address and other trap parameters in the targetAddr and targetParam tables. Use the following command to specify the username used with this targetParam table:

snmp-server target-parameters <1-16>user-name

For example:

ex2500(config)# snmp-server target-address 10 name v1trap address 10.70.70.190

ex2500(config)# snmp-server target-address 10 parameters-name v1param ex2500(config)# snmp-server target-address 10 taglist v1param ex2500(config)# snmp-server target-parameters 10 name v1param ex2500(config)# snmp-server target-parameters 10 user-name v1only ex2500(config)# snmp-server target-parameters 10 message snmpv1

SNMPv2 Trap Host Configuration

The SNMPv2 trap host configuration is similar to the SNMPv1 trap host configuration. Wherever you specify the model, use snmpv2 instead of snmpv1.

ex2500(config)# snmp-server read-community public

ex2500(config)# snmp-server target-address 1 name v2trap2 address 10.70.70.190 ex2500(config)# snmp-server target-address 1 parameters-name v2param2 ex2500(config)# snmp-server target-address 1 taglist v2param2 ex2500(config)# snmp-server target-parameters 1 name v2param2 ex2500(config)# snmp-server target-parameters 1 user-name v2only ex2500(config)# snmp-server target-parameters 1 message snmpv2 ex2500(config)# snmp-server notify 1 name public

ex2500(config)# snmp-server notify 1 tag v2param2
