I am installing a new ASA5510 running version 8.03 software and using ASDM-603.
When using the ASDM to add snmp-server hosts, most of the ip addresses in the subnet work fine. However, I have two addresses that consistently pop up an error "IP Address conflicts with interface broadcast address"
One of the addresses is 192.168.100.79 and the management interface ip is 192.168.100.252 with a 24 bit mask. It is odd because I can add 192.168.100.78 or 80 just not the 79. BTW, 88 is a second one I have tried and got the same error. I have several in the same subnet that worked just fine.
Anyone know what may cause this?
Thanks in advance.
This is bug CSCsm15806, where if you have any interface on the ASA configured with a 255.255.255.252 mask, ASDM throws an error when you try and add a snmp-server with a host address that would be a broadcast address with that mask. The interface doesn't matter, it's just if you have any interface with a 255.255.255.252 mask on it.
The bug was only fixed 4 days ago so is not yet in an official release. For the time being, just add the snmp-server via the CLI and you'll be OK, but upgrade to 6.0(4) when you see it on the web site.
