Configuring FDDI VLANs on the Switch
To create a new FDDI VLAN, perform this task in privileged mode:
Task
Step 1 Create a new FDDI or FDDI NET-type VLAN.
Step 2
Verify the VLAN configuration.

Enter the show pvlan command to display information about the private VLANs. The show pvlan
command displays information about the private VLANs only when the primary private VLAN is
up.
Entering the set pvlan mapping or the clear pvlan mapping command on the supervisor engine
generates the MSFC syslog messages. See the following for an example:
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Created a private vlan mapping, Primary 200, Secondary 201
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 101
Enter the interface vlan command to configure the Layer 3 parameters only for the primary private
VLANs.
On the supervisor engine, you cannot create the isolated or community VLANs using the VLAN
numbers for which the interface vlan commands have been entered on the MSFC.
The ARP entries that are learned on the Layer 3 private VLAN interfaces are sticky ARP entries (we
recommend that you display and verify the private VLAN interface ARP entries).
For security reasons, the private VLAN interface sticky ARP entries do not age out. Connecting new
equipment with the same IP address generates a message and the ARP entry is not created.
Because the private VLAN interface ARP entries do not age out, you must manually remove the
private VLAN interface ARP entries if a MAC address changes.
You can add or remove the private VLAN ARP entries manually as follows:
obelix-rp(config)# no arp 11.1.3.30
IP ARP:Deleting Sticky ARP entry 11.1.3.30
obelix-rp(config)# arp 11.1.3.30 0000.5403.2356 arpa
IP ARP:Overwriting Sticky ARP entry 11.1.3.30, hw:00d0.bb09.266e by hw:0000.5403.2356
Some commands clear and recreate the private VLAN mapping as follows:
obelix-rp(config)# xns routing
obelix-rp(config)#
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 102
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 103
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 102
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 103
