Configuring VLANs
• Spanning Tree Protocol (STP) type for TrCRF VLANs
• VLAN number to use when translating from one VLAN type to another
You can cause inconsistency in the VLAN database if you attempt to manually delete the vlan.dat file. If you
want to modify the VLAN configuration, follow the procedures in this section.
Creating or Modifying an Ethernet VLAN
Before You Begin
With VTP version 1 and 2, if the switch is in VTP transparent mode, you can assign VLAN IDs greater than
1006, but they are not added to the VLAN database.
The switch supports only Ethernet interfaces. Because FDDI and Token Ring VLANs are not locally supported,
you only configure FDDI and Token Ring media-specific characteristics for VTP global advertisements to
other switches.
Although the switch does not support Token Ring connections, a remote device with Token Ring connections
could be managed from one of the supported switches. Switches running VTP Version 2 advertise information
about these Token Ring VLANs:
• Token Ring TrBRF VLANs
• Token Ring TrCRF VLANs
SUMMARY STEPS
1. configure terminal
2. vlan vlan-id
3. name vlan-name
4. mtu mtu-size
5. media { ethernet | fd-net | fddi | tokenring | trn-net }
6. remote-span
7. end
8. show vlan {name vlan-name | id vlan-id}
