Hey, hey, what a day
Well, I passed my CCIE qualification exam today. What a great test. First shot and I nailed it, so I couldn't be happier. Now, onward to prepare for the lab exam. Thanks to this group and the great discussions that take place here, it is a valuable resource packed with great people!

Re: Equal cost switching
It will not use both paths as that would defeat the purpose of spanning tree. To force the paths to both be used, you would have to configure the ports in a channel. There should be plenty of good information about spanning tree operation and port channeling at www.cisco.com Jason Fletcher "AndyD" wrote in message 96p2uk$rt5$[EMAIL PROTECTED]... Spanning tree is supposed to choose the one best switched path. But if you set up two equal cost paths, will it use both? Is there a way to force it to use the bandwidth from both paths?

Re: Needing advice on a switch for a LAN
Well, www.cisco.com would be a good place to start. Specifically, you may want to check out this link: http://www.cisco.com/pcgi-bin/front.x/rsmp/pctpstPublic/servlet/PctpstPublic ?_file=/selectionTool.htmlsessionid=categoryid=1 watch all the word wrap. This will help you select what switch is right for you based on your criteria. Then you can find more information on the switches that you are interested in at Cisco's product pages accessible from their home page.

Re: Cat 3548 not seeing vlans
errata...didn't mean to say the revision was greater than the 5500 that you plugged the 3548 into. The revision would be greater than your VTP domain server, could be either of your 5500's. Jason Fletcher CCNP "Jason Fletcher" wrote in message 96mvpu$nre$[EMAIL PROTECTED]... Hmm, certainly a trunking problem I would say, might want to check that both trunk ports (the 5500 and 3548) are not set to auto as they will never trunk (and auto is the Cisco default). You should set the trunk port on the 5500 to desirable. BUT, I think this is the problemYOU GOT LUCKY! I think that you probably initially set all the VTP AND VLAN information on the 3548 didn't you? It doesn't matter that the switch was set to VTP client. If the VTP domain configuration revision is set higher on the 3548 then on the 5500 that you plugged it into then the 5500's are pulling their VTP and VLAN info from the 3548. That is to say that if you had not configured the VLAN's on the 3548 prior to trunking it to the 5500 then your entire network would have gone down as the VLAN configs on all the other switches would have taken their config from the new "client". Well, I would first check to see that the revision is indeed greater on the new switch than on your VTP server (use the show vtp domain command) If it is greater, then I would reset the revision by changing he domain name on the new switch to some dummy domain...like set vtp domain reset then change it back to the correct domain. This reset's the revision back to 0 and everything should start working properly. Well, it may just be a shot in the dark, but I think one of the above two items is the issue.

Re: NAT HSRP Problem
I don't think you can do this? The standby router doesn't have the translation table of the active router, so when the active router went down you will lose your connection.

Re: Cisco to 3Com Dot1Q trunks and VLANs
I may be wrong, because I am still studying this stuff, but I believe that Per-VLAN STP is a Cisco critter...ISL Jason Fletcher ""Lance Hubbard"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... This brings to mind a question for the group: Will Cisco's 802.1Q implementation support per-VLAN STP? Cheers, Lance From: "Chris H" [EMAIL PROTECTED] Reply-To: "Chris H" [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: Re: Cisco to 3Com Dot1Q trunks and VLANs Date: Mon, 15 Jan 2001 19:41:55 - Michale, I have dot1q trunks running across Cisco MDF switches and Nortel IDF switches. We found that Cisco and Nortel run two different versions of Spanning Tree, both of which are 802.1q compliant. The difference between the two is that Cisco's portfast feature, and Nortel's faststart feature are different, where portfast has a default forward delay of 15 seconds, and faststart doesn't implement the forward delay feature. This resulted in a huge amount of TCN's (topology change notifications), particularly in the morning, when all end users are booting up their pc's and changing to 'forwarding' mode in spanning tree. As a result, we opened a ticket with Nortel, and they agreed to add forward delay to their switching code to correct this problem. I would check the STP documentation on both vendors, and determine if all the default values are the same, what the default root bridge priority number is with both vendors, who you have configured as your root bridge, etc. I would even plug a sniffer in and capture some traffic... Draw out a spanning tree diagram, and document your root bridge, and the subsequent switches in the spanning tree. Those are just some suggestions... Hope you find some results.
