Deleting An Isolated Or Community Vlan; Deleting A Private Vlan Mapping - Cisco WS-C2948G-GE-TX Configuration Manual

Chapter 10 Configuring VLANs

Deleting an Isolated or Community VLAN

If you delete an isolated or community VLAN, the binding with the primary VLAN is broken, any
isolated or community ports that are associated to the VLAN become inactive, and any related mappings
on the promiscuous port(s) are deleted.
To delete a VLAN on the switch, perform this task in privileged mode:
Task
Delete an isolated or community VLAN.
This example shows how to delete the community VLAN 902:
Console> (enable) clear vlan 902
This command will de-activate all ports on vlan 902
Do you want to continue (y/n) [n]?y
Vlan 902 deleted
Console> (enable)

Deleting a Private VLAN Mapping

If you delete the private VLAN mapping, the connectivity breaks between the isolated or community
ports and the promiscuous port. If you delete all the mappings on a promiscuous port, the promiscuous
port becomes inactive. When a private VLAN port is set to inactive, it displays "pvlan-" as its VLAN
number in the show port output.
You might set a private VLAN port to inactive for the following reasons:
•
•
To delete a port mapping from a private VLAN, perform this task in privileged mode:
Task
Delete the port mapping from the private VLAN. clear pvlan mapping primary_vlan {isolated |
This example shows how to delete the mapping of VLAN 902 to 901, previously set on ports 3/2 through
3/5:
Console> (enable) clear pvlan mapping 901 902 3/2-5
Successfully cleared mapping between 901 and 902 on 3/2-5
Console> (enable)
