'Show spanning-tree int' for the port that is not working shows that the port is in a forwarding state. It has the correct root and path costs so it is getting that info correctly. I have been reading on a subject of Spanning tree instances though and that a 3500XL series switch can only...

No they are different ports and different switches. IOS is not the factor either, as I tried switches with different versions. It is hard to recreate sometimes and it might be VLAN XXX having a problem on one switch and vlan yyy on another. Doing a show int on the port shows that there are no...

There are about 40 Vlans, about half will be removed when the ip conversion is complete. I have turned on pruning on the 6500s, but have not changed the "allowed vlans" so that only the needed vlans are there. One reason being that I am trying to clean up our network to get only 2 or three...

This is a mind boggler to me and after looking at it for a while I am at the point where I am not advancing in any cure or it. Maybe someone knows exactly the problem and I am just spacing it out for some reason. Here is the problem. We have many vlans and we need to go through a readdressing...

Came across your post in my own search for a solution to this problem. This is what I have surmised as of now. It's a feature of Outlook (or Microsoft or MAPI). There are two standards involved here, the SMTP standard used for sending email and the IMAP4 standard for receiving mail. The SMTP...

Thanks ADB100, I have been looking into it and modifying the aging-timers and like you said the problem is there, but diminished. Thanks for the post Ken

A question for anyone who can help? I am seeing an odd thing happening on our network. We have a switched network with 3548s in closests and 6509s with MSFC as the core. In the VLANs I am seeing traffic that I should not be seeing. If my pc's ip address is 172.16.16.5 (255.255.240.0), I...

Not sure if many people wrestle with this problem, but I generate scripts every now and would like to utilize a clear screen at time. Well this is what I came up with: use the "send" command with some escape characters. send {line-number | * | aux number | console number | tty number | vty...

I know this looks like an old thread and not sure if anyone cares. I too have been looking to find a way to clear the screen. Well this is what I came up with: use the "send" command with some escape characters. send {line-number | * | aux number | console number | tty number | vty number}...

I too tried everything and was afraid that I just didn't have something set right or overlooked something. Thanks for the info you provided. I will look for an alternative method.

I have a question dealing with a project I am working on. It may seem unconventional and that is probably why it is not working the way I want it to. What i would like to do is set up NAT on a router so that both sides o the networks look as though the machine they are connecting to looks...

We have an in-house written application that would like to use udp broadcasts to all PCs ( about 1500 )using this application across subnets. We have several subnets and one or 2 machines will do the actual sending out of messages. These broadcast messages will not be used that frequently...
