Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide for Cisco 4451-X ISR
DETAILED STEPS
Command or Action Purpose
Step 1
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 2
interface Ethernet-Internal slot/0/0
Example:
Router(config)# interface
Ethernet-Internal 1/0/0
Configures the Cisco SM-X Layer 2/3 EtherSwitch Service Module.
Step 3
service instance id ethernet
Example:
Router(config-if)# service instance 1
ethernet
Creates a service instance on an interface and enters service instance
configuration mode.
Step 4
encapsulation vlan id dot1q
[second-dot1q vlan id]
Example:
Router(config-if-srv)# encapsulation
dot1Q 10
Defines the encapsulation type and enables IEEE 802.1Q encapsulation
of traffic on a specified subinterface in a VLAN.
• vlan-id — Virtual LAN identifier. The allowed range is from 1 to
4094. For the IEEE 802.1Q-in-Q VLAN Tag Termination feature,
the first instance of this argument defines the outer VLAN ID, and
the second and subsequent instances define the inner VLAN ID.
• native — (Optional) Sets the VLAN ID value of the port to the
value specified by the vlan-id argument.
Note This keyword is not supported by the IEEE 802.1Q-in-Q
VLAN Tag Termination feature.
• second-dot1q — Supports the IEEE 802.1Q-in-Q VLAN Tag
Termination feature by allowing an inner VLAN ID to be
configured.
• any — Sets the inner VLAN ID value to a number that is not
configured on any other subinterface.
Note The any keyword in the second-dot1q command is not
supported on a subinterface configured for IP over Q-in-Q
(IPoQ-in-Q) because IP routing is not supported on ambiguous
subinterfaces.
