Hi All:
  I have 2 Cisco Cat 5500 with RSM cards & variable net mask 255.255.252.0. 
NETMON discovers the IP addresses, ok. The Event display window shows  Added 
and 10 minutes later it shows Deleted for the same interfaces. This 2 switches 
are up all the time and function as backup to eachother(hot stand by). We are 
also using vlans.This problem was NOT there on NV 4.2.1.
Any ideas?
