Configuring Uni-Eni Vlans; Configuration Guidelines - Cisco ME 3400 Software Configuration Manual

Creating and Modifying VLANs
Beginning in privileged EXEC mode, follow these steps to release a VLAN ID that is assigned to an
internal VLAN and to create an extended-range VLAN with that ID:
Command
Step 1 show vlan internal usage
Step 2 configure terminal
Step 3 interface interface-id
Step 4
shutdown
Step 5
exit
Step 6 vlan vlan-id
Step 7 exit
Step 8
interface interface-id
Step 9
no shutdown
Step 10
end
Step 11 copy running-config startup config

Configuring UNI-ENI VLANs

By default, every VLAN configured on the switch is a UNI-ENI isolated VLAN. You can change VLAN
configuration to that of a UNI-ENI community VLAN, a private VLAN. or an RSPAN VLAN. You can
also change the configuration of one of these VLANs to the default of a UNI-ENI isolated VLAN.

Configuration Guidelines

These are the guidelines for UNI-ENI VLAN configuration:

Purpose
Display the VLAN IDs being used internally by the switch. If the VLAN
ID that you want to use is an internal VLAN, the display shows the routed
port that is using the VLAN ID. Enter that port number in Step 3.
Enter global configuration mode.
Specify the interface ID for the routed port that is using the VLAN ID,
and enter interface configuration mode.
Shut down the port to release the internal VLAN ID.
Return to global configuration mode.
Enter the new extended-range VLAN ID, and enter config-vlan mode.
Exit from config-vlan mode, and return to global configuration mode.
Specify the interface ID for the routed port that you shut down in Step 4,
and enter interface configuration mode.
Re-enable the routed port. It will be assigned a new internal VLAN ID.
Return to privileged EXEC mode.
(Optional) Save your entries in the switch startup configuration file.
UNI-ENI isolated VLANs have no effect on NNI ports.
A UNI-ENI community VLAN is like a traditional VLAN except that it can include no more than a
combination of eight UNIs and ENIs.
To change a VLAN type, first enter the vlan vlan-id global configuration command to enter VLAN
configuration mode:
To change a VLAN from UNI-ENI isolated VLAN to a private VLAN, enter the private-vlan
–
VLAN configuration command.
To change a UNI-ENI community VLAN to a private VLAN, you must first remove the
–
community VLAN type by entering the no uni-vlan VLAN configuration command. Then enter
the private-vlan VLAN configuration command.
To change a VLAN from a UNI-ENI isolated VLAN to an RSPAN VLAN, enter the rspan-vlan
–
VLAN configuration command.
