Dear All,
Is there anyway to create extended vlan(from 1006 to 1010) on my cisco 7604? These are existing customer vlan which I planned to move to this 7604 but unfortunately cant. I believe only FDDI and Token ring vlan unable to remove. Expert please advice.

Do you have any L3 port configured in the switch with the command 'no switchport'? Those L3 swithports are using these VLAN
Also check if tou have a descending VLAN allocation option:
CRPsgMCAmissi11(config)#vlan internal allocation policy ?
ascending Allocate internal VLAN in ascending order

As Cisco Freak said, those vlans are being allocated for internal use
Layer 3 LAN ports, WAN interfaces and subinterfaces, and some software features use internal VLANs in the extended range. You cannot use an extended range VLAN that has been allocated for internal use.
In order to use them, you will need to use a descending vlan allocation option, to start allocation from vlan 4094 and down, to do this you will need to apply the command:
vlan internal allocation policy descending
And then reboot your switch, so the internal vlans get reallocated
For more info refer to this configuration guide:
