Have a production campus LAN network primarily running with 3508Gs and 3524XL data switches with gigabit fiber uplinks. All switches are currently running ISL Vlan trunking between the uplink ports. There's also a 2620 router running ISL fastethernet subinterfaces configured with encapsulation ISL.
I have some non-cisco network devices that only support 802.1q vlan trunking. I already know the 802.1q trunking on non-cisco equipment works ok with cisco devices running 802.1q trunking. However, when I deploy the non-cisco equipment in the production campus LAN, can I have some trunk ports running 802.1q trunking and other trunk ports running ISL. Bottom line: Can ISL and 802.1q co-exist or do I have to migrate entire LAN to 802.1q vlan trunking?? regards, dj Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=73511&t=73511 -------------------------------------------------- **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html
