RE: ISL Trunking [7:30728]
Cisco may recommend it but I believe it really depends on your perspective. For example, if your environment's policy is to have all of your ports enabled and ready for a connection, then it is conceivable that anyone could get onto your administrative rail by simply finding a jack to plug in to. Sniff the traffic, etc. On the other hand, if you lock down your switch ports it's not that big of an issue. Any way I've been in both types of environments and I guess it also depends on how security conscience the organization is.

Let me clarify my statement: ...Some Catalysts may just simply not allow dropping VLAN 1, as it can be the only Administrative Vlan. What I meant by this is that based on the Version of IOS/CAT OS, that it would not accept any other VLAN as the Administrative Vlan. I know for a fact that you can specify other Vlans as the Administrative Vlan on many of the CAT 5x00/6x00 switches. I just was suggesting that stranger things could happen for the lower-end switches that have low port density, and other types of limitations. After all, Cisco hasn't made a considerable effort to make ALL their switches run Native IOS or CAT OS... it's been a mix/match from all the competitors they've acquired! :) Mark Odette II ... who obviously doesn't have experience with EVERY catalyst switch on the market, and admits it readily. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Darren Crawford Sent: Thursday, January 03, 2002 11:32 AM To: [EMAIL PROTECTED] Subject: RE: ISL Trunking [7:30728] I must disagree with VLAN 1 being the only administrative VLAN.

You can clear the trunks for anything 2-1005 and 1025-4096 (6000 series) but I don't believe it will allow you to do that with the default VLAN.
