Yes its exactly the same, same config, same interface addresses and same
hardware, only difference is the Hostname and the physical location, but
NetView doesnt even see the slave router. We maintain another tool for those
switches, called Extreme Networks EPICenter, which recieves the traps and
generates the events/alarms. Not even this tool would see if they changed the
status without those traps.
They were trying to configure an additional NMS VLAN but this is another story

I think syslog messages/traps are the way to go in such scenarios.

Betreff: RE: [nv-l] HSRP
When you say the router configs are identical, does that imply they have the
same interface addresses? Its one thing to have a "parallel" config where the
interfaces are similar in addressing scheme and its another to have identical
configs (which cannot participate in the same networks). If the configs are
"parallel" then the sysname can be unique on both routers.
