Can I use Vlans 1002-1005 etc.

[les.flack]

Can anyone confirm if it is OK to reuse (for ethernet) Vlan's 1002-1005?

Also why do CatOS switches not support config of VLANs 1006-1024.

no, you cannot use VLANs 1002-1005 for ethernet. these are FDDI & TokenRing default VLANs and cannot be deleted or used for ethernet.

also, CatOS does support vlans 1006-1024. these are part of the 'extended VLAN range' and need to be manually configured on switches. VTP will not propagate VLANs in the 'extended VLAN range'.

reserved VLANs: 0 & 4095

VLAN 1: default vlan; cannot be deleted; can be used

VLAN 2-1001: ethernet VLANs; can be used

VLAN 1002-1005: FDDI & TokenRing VLANs. cannot be deleted

extended VLANs: 1006-4094: ethernet VLANs only

1002-1005 cannot be used for ethernet. They are ment for FDDI and Token Ring. For more info, try this link:

Hope this helps.
