DLSW, trying to determine if clients are using the bridge.

I've got a site that's bridged up to a foreign router using DLSW for mainframe access. My DLSW bridge is in place and connected but I'm not sure if anyone is really using it anymore. No one here seems to know if it's being used. I've issued the "show dlsw circuits history detail" command and from the output it look like it was maybe last used in August of 2004 if I'm translating this correctly. Below is the ouput. Can some one please tell me if what I think is the case truly correct?

Re: DLSW, trying to determine if clients are using the bridge.

Hello Jeff,

is that the only entry you get (the one shown in your output) ? The circuit history is being kept for the last 32 circuits, if the one in your output is the only one you see, that means indeed that the last connection was on August 7, 2004.

When you do a ´show dlsw circuits history´ (that is, without the ´details´ keyword), you will see the last 32 entries. If you then use the command with the ´details´ keyword, and the latest disconnect was indeed on August 7, 2004, I think it can be safely assumed that noone has been using the bridge since then.

Here is the link to the relevant command reference, which explains all the fields shown in the output:

This is an interesting question. I have done some DLSw but unfortunately this is beyond my level to answer authoritatively. I wonder if you would not find more people with this expertise in the Enterprise Data Center Networking forum. Perhaps you can post there and may get better response.

That is not the only entry I get with the "show dlsw circuits history" command but the entry I pasted had the latest date. All other entries were older than August 7, 2004. So, I'm guessing as you stated that the last use of the bridge was on August 7th 2004.

Thanks!
