Problem with "X25 MAP QLLC" for activate Microsoft SNA Server

Hi!

I have 1 router (CISCO 2501) with 73 connections configured on it. They are 73 "X25 MAP QLLC...".

Each connection has a VMAC address to configure in the server (Microsoft SNA Server).

Example:

X25 MAP QLLC 4000.3500.0001 999910004107101

X25 MAP QLLC 4000.3500.0002 999910004107102

...

X25 MAP QLLC 4000.3500.0073 999910004107173 (last)

In each SNA server I have the XID (ID num and Id block by VTAM) and the VMAC (by Router).

My problem is that the connections are going to down frequently.

Sometimes I have 30 connections up and sometimes 20 or less.

Sometimes all the connections goes down.

The total of Virtual circuits are 500 in the router!!!

The question is:

My router (CISCO 2501) support a lot of "X25 map QLLC" connections?

I have tried to put 2 routers with 36 connections for each.

When the connection goes up 30 activated, the router begins the problems.

Please, help me

Thanks

Hi,

i take a guess.

You are saying that you use a cisco2501 router.

How much free memory do you have after around 30 connections are up and running?

thanks...

Hi Matthias,

The memory is OK. No problem.

I checked them. Between 80 and 90% free.
