Description: Switches losing connectivity to random servers, showing ARP entries on shut down interfaces, what is going on?
network (6403) c# (3599) tool (1779) cisco (1003) routing (197) ccna (167) ccnp (100) switching (86) configurations (8)
This all started when I introduced a new network monitoring tool on to the network, the tool was “cisco prime”, but before I say any more lets be clear the issue here has nothing to do with prime which is a great tool for managing cisco devices. I noticed that when pushing new IOS files and backing up switch configuration that some time they would seem to lose network connectivity. I was able to ping them and ssh to them from my desktop, but they would simple not speak to the prime server.
So lets start with the set up (ip address modified of course)
Prime server – a vmware guest , in vlan 1, ip address 10.10.224.98/21
