The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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.
Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the "Feature Information for SNMP Support for VLAN Subinterfaces" section.

To configure SNMP Support for VLAN Subinterfaces, complete the tasks in the following section:
•Enabling the SNMP Agent on VLAN Subinterfaces
Perform the following task to enable the SNMP agent on VLAN subinterfaces.
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
•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
