On this same subject, how secure or how vulnerable is ISL or dot1q trunking? Is it vulnerable to arp attacks?

[7:33758] It might be an issue of installed base, or lack thereof. I believe recent CatOS releases have corrected this, but for a long while, the Cat 400x series did ISL on trunks, while doing 802.1q on ports. Older boxes, of course, may only do ISL. In these days of tight budgets it can be difficult to convince customers to upgrade absolutely, everyone should upgrade to the open standard. absolutely, everyone should migrate from token ring to ethernet. absolutely, everyone should eliminate native IPX, NetBEUI, and AppleTalk from their networks. ;-> Chuck ""Peter van Oene"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > What are the current advantages for running ISL over 802.1q?
