Hi,

I have a few SMC switches in my Network. I know that 802.1q has become almost the standard for VLAN. I came to know that SMC uses Cisco IOS. I was just wondering if SMC switches support ISL?

That mostly depends on the IOS version that's running on this switch.
If it's using Cisco IOS, try to do the following:

# conf t
(config)# int Fa0/1
(config-if)#switchport trunk encap ?
  dot1q      Interface uses only 802.1q trunking encapsulation when trunking
  isl        Interface uses only ISL trunking encapsulation when trunking
  negotiate  Device will negotiate trunking encapsulation with peer on
             interface

(config-if)#

If it lists isl here, it's supported.

My models do not support your command. My two models are:

SMC8024L2
SMC6128L2

And I am not sure which version of IOS is running on these boxes.

and I suppose they are not using cisco ios (don't think cisco sells it's OS or licences), but have cisco-like interface, which is very common

more likely it is their own (or bought from someone, not likely Cisco) with cisco like CLI interface.
Cisco IOS is very sophisticated and almost bullet proof feature reach OS, so I don't think that SMC just bought it from Cisco for its own devices.

as of curiosity why don't you want to use standard 802.1q?

Well offcourse 802.1Q is a universal standard but I was thinking that maybe in a hybrid environment with Cisco, SMC together we can make ISL based VLAN. Never mind I guess its not Cisco IOS.

Especially in a hybrid environment you should stick with standards as they should be equally good implemented on several platforms.

so the only option for you is to stick with standard 802.1q on both, cisco and smc devices.
