vlan range

can anyone pls tell abt the exact range of vlans..

some docs says its from 1-4096 and some says 1-1005.even in extended range

some docs says extended range starts from 1006-4096 and some as 1024-4096.

my understanding is

vlan std range :1-1005(with 1001-1005 reserved for fddi etc. )

vlan extended range:- 1006-4095(and extended can be configured only on switch with

vtp mode transparent)

is it right??

is that trunking method (isl n 802.1q) something to do with vlan range.

Hi Arun,

Extended range vlans are from 1006-4096. Cisco IOS switches support the exetnded range vlans in the range 1006-4096. However, CATOS switches donot support 1006-1024. This is the only limitation that you have. If you have a mix of IOS and CatOS switches in your network, you have to make sure that 1006-1024 do not extend to those switches.

Vlan Std range is from 1-1001 (1002-1005 are reserved)

Extended range is the same but differs on CATOS switches.

Yes, your switch has to be in VTP transparent mode to configure the extended range vlans.

HTH,Please rate if it does.

hey amith thanks... :)

what abt the vlan range in isl and 802.1q trunks????


AFAIK formerly ISL supports the normal VLAN range only, while 802.1Q supports the extended range.

[edit] The valid range of user-configured Inter-Switch Link (ISL) VLANs is 1 to 1000 and 1025 to 4094. The valid range of VLANs that are specified in the IEEE 802.1Q standard is 0-4095.

NOTE: You can only create and delete extended-range VLANs from the CLI or SNMP, you can't use the VLAN database mode.

HTH, please do rate all helpful replies,

Does these rules apply to ISR Router as well as Cisco switches ? It seems that on Cisco ISR we can't create vlans upper to 1001. Do you think that by changing/upgrading the ios on an ISR, we finally can create a vlan 1280 for example ?

Best Regards,

Hi Arun,

There are a maximum of 4096 possible values ranging from 0 to 4095. Some of these values are reserved as shown below:

Value Meaning 0 Contains user_priority data (802.1Q) 1 Default Port VID (802.1Q) 4095 Reserved (802.1Q)

Normal Range IDs

- 1 – 1005

- 1002 – 1005 are reserved for Token Ring and FDDI VLANs

- 1 and 1002 to 1005 are automatically created and cannot be removed

- Normal rage VLANs IS store in the vlan.dat file in the flash memory.

Extended Range IDs

- 1006 – 4094

-  Designed for service providers

- Have fewer options than normal range VLANs

-  Stored in the running configuration file
