Chapter 7 Configuring VLANs on the ML-Series Card
IEEE 802.1Q VLAN Configuration
Note In a bridge group on the ML-Series card, the VLAN ID does not have to be uniform across interfaces
that belong to that bridge group. For example, a bridge-group can connect from a VLAN ID subinterface
to a subinterface with a different VLAN ID, and then frames entering with one VLAN ID can be changed
to exit with a different VLAN ID. This is know as VLAN translation.
Note IP routing is enabled by default. To enable bridging, enter the no ip routing or bridge IRB command.
Note Native VLAN frames transmitted on the interface are normally untagged. All untagged frames received
on the interface are associated with the native VLAN, which is always VLAN 1. Use the command
encapsulation dot1q 1 native.
IEEE 802.1Q VLAN Configuration
The VLAN configuration example for the ML-Series card shown in Figure 7-2 depicts the following
VLANs:
• Fast Ethernet subinterface 0.1 is in the IEEE 802.1Q native VLAN 1.
• Fast Ethernet subinterface 0.2 is in the IEEE 802.1Q VLAN 2.
• Fast Ethernet subinterface 0.3 is in the IEEE 802.1Q VLAN 3.
• Fast Ethernet subinterface 0.4 is in the IEEE 802.1Q VLAN 4.
