Hey everyone,
I know that sometimes, depending on the MIB table of the device, NPM can report discards on an interface indicating a link issue. However in actuality it could be normal device operation. I am running into that situation with several sets of ASA-5505's. In our environment, we utilize many ASA platforms, from ASA-5550's to ASA-5505's. The four ASA-5505's are the only devices experiencing this issue. Since all ASA-5505's are experincing this issue, I starting looking at what NPM could actually be reporting. The main difference between the ASA-5505 and all other ASA's, besides horsepower, is that there is a built-in switch. Interfaces on the switch are assinged to VLANS. Then there is a VLAN ACL that is used for denying traffic. I believe that NPM is reporting "discards" on these ASA-5505 interfaces due to VACL drops, which would be normal operation.
Has anyone else experienced this issue? Any information would be appreciated.
Thanks
