This feature module describes the SNMP Support for VLAN Subinterfaces feature. It includes information on the benefits of the new feature, supported platforms, supported standards, and the commands necessary to configure the SNMP Support for VLAN Subinterfaces feature.

The SNMP Support for VLAN Subinterfaces feature provides mib-2 interfaces sparse table support for Fast Ethernet subinterfaces. This enhancement is similar to the functionality supported in Frame Relay subinterfaces.

Finding Feature Information

How to SNMP Support for VLAN Subinterfaces

To configure SNMP Support for VLAN Subinterfaces, complete the tasks in the following section:

•Enabling the SNMP Agent on VLAN Subinterfaces

Enabling the SNMP Agent on VLAN Subinterfaces

Perform the following task to enable the SNMP agent on VLAN subinterfaces.

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp community public

4. interface type slot/port

5. encapsulation isl vlan-identifier

6. ip address ip-address mask

7. end

8. show vlans

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	snmp community string Example: Router(config)# snmp community public	Enables the SNMP agent for remote access.
Step 4	interface type slot/port Example: Router(config)# interface FastEthernet 0/1.1	Selects a particular Fast Ethernet interface for configuration.
Step 5	encapsulation isl vlan-identifier Example: Router(config-if)#  encapsulation isl 10	Enables the Inter-Switch Link.
Step 6	ip address ip-address mask Example: Router(config)# ip address 192.168.10.1 255.255.255.0	Sets a primary or secondary IP address for an interface.
Step 7	end Example: Router(config-if)# end	Returns to privileged EXEC mode.
Step 8	show vlans Example: Router# show vlans	Displays VLAN subinterfaces.

Configuration Examples for SNMP Support for VLAN Subinterfaces

•Example: Enabling the SNMP Agent for VLAN Subinterfaces

Example: Enabling the SNMP Agent for VLAN Subinterfaces

The following configuration example shows you how to enable the SNMP agent on the router with VLAN subinterfaces to monitor the SNMP application remotely:

snmp community public

!

interface FastEthernet4/0.100

 encapsulation isl 100

 ip address 192.168.10.21 255.255.255.0

!

interface FastEthernet4/0.200

 encapsulation isl 200

 ip address 172.21.200.11 255.255.255.0

!

interface FastEthernet4/1.1

 encapsulation isl 10

 ip address 171.69.2.111 255.255.255.0
