Re: new version of 802.1q?

[Joe Martin]

I was originally told that when the 802.1q spec was released that it only supported 1 STP period.  I was then told and have seen some docs that said that this was changed to one STP per vlan.   JOE CCIE 5917   ""Andy Harding"" <[EMAIL PROTECTED]> wrote in message 01f801bfce8a$c41bace0$[EMAIL PROTECTED]">news:01f801bfce8a$c41bace0$[EMAIL PROTECTED]... have been having (semi) argument at work about dot1q versus ISL   my understanding is that dot 1q runs one instance of spanning tree per trunk, rather than per vlan as ISL does - hence if one VLAN is blocking then dot1q disables the entire trunk   A collegue of mine reckons that dot 1q now does as per ISL and runs STP on a per-vlan basis, but the 802.1q spec has changed without the # changing   someone help me out here...   thanks   Andy
