Trunking in ISL or 802.10?

[adamz]

Hello,

I have a question about the config I have pasted below. In the config below, it says VLAN ISL Id: 1002....but it then states VLAN 802.10. Does this mean that the trunk is running 802.10 or ISL?

switch1(vlan)#show

VLAN ISL Id: 1002

Name: fddi-default

Media Type: FDDI

VLAN 802.10 Id: 101002

State: Operational

MTU: 1500

VLAN ISL Id: 1004

Name: fddinet-default

Media Type: FDDI Net

VLAN 802.10 Id: 101004

State: Operational

MTU: 1500

Help is much appreciated.

hi,

vlan 1002 and vlan 1004 is default vlans for FDDI. these vlans are predefined on the switch and can be transported via ISL encapsulation. Trunk runs with ISL and it carries FDDI vlan 1002 and 1004.

Yes, the 802.10 standard is for FDDI mainly, more info can be found here:

Perhaps your confusing 802.10 with 802.1Q?
