RE: [NV-L] Acknowledging UNREACHABLE interfaces





Does the ACK clear from the network properly when connectivity is restored?

That's how it works, in my experience. I usually ack the network.

[NV-L] Acknowledging UNREACHABLE interfaces                

                                 




I am running Netview for Windows 7.1.5 and, when a router goes Unreachable, acknowledging the interfaces does not propagate up.  The node and networks remain white.  This only happens for unreachable; acknowledging down interfaces on a marginal router/node will propagate as expected.
 
I found hits regarding the variable OVW_NO_UNREACHABLE_PROPAGATION, but that seems to control the propagation of unreachable, not the ACK, and the related APAR states the variable has no effect when all interfaces are unreachable, anyway.
 
One workaround is to ACK the node, also, be we have had occasions where the node ACK does not clear when the interfaces do, and it remains dark green event though it is completely up.
 
Can anyone confirm similar behavior and offer any better solution?
 
 
Thanks,
