Hi,
I am running DLSW Ethernet redundancy on 2 x 7204 VXR routers. The one acts as the master for the odd VLAN's and the other as the master for the even VLAN's. The 7204's connect to 2 x 6509 switches via ISL trunking.
The problem I have is that if I disable DLSw on one of the 7204's, it takes quite a long time for the worksession stations to re-establish their sessions.
Any help welcome..
Dean Young.

Ypu can reduce the SNA timer. The following URL describes how to do it -

HI,
The url points to buffer tuning. I could not find any timer settings. Could you please advise?

Thanks. I did change the parameter, but it did not make any difference.
I am running PCOMMS 5.0.
What I found was the following:
I connect to the mainframe via 7204_1 and then disable DLSW on this router. It takes exactly 1minute and 25 seconds for my session to be re-established via the backup 7204.
I was wondering if there is a timer that will speed up this process. It seems as if the source and destination MAC binding has to be released and then setup via the backup 7204.
Regards
Dean
