Ax man:

What the heck is DLSW ER+?? Never heard of it...

As far as DLSW+ is concerned, the short answer to your question is both.

The long answer is as follows...

SSP is used. Switch-to-Switch Protocol (SSP) is a protocol used between DLSw nodes (routers) to establish connections, locate resources, forward data, and handle flow control and error recovery. This is truly the essence of DLSw.

In general, SSP does not provide for full routing between nodes because this is generally handled by common routing protocols such as RIP, OSPF, or IGRP/EIGRP. Instead, SSP switches packets at the SNA data link layer.

It also encapsulates packets in TCP/IP for transport over IP-based networks and uses TCP as a means of reliable transport between DLSw nodes.


If so, please rate my post.

Thanks for your response..DLSw+ ER is ethernet redundancy, that works a bit different from the usual bridged DLSw..
