ARP table size mib for Cat6509

jjiles · ‎02-08-2007

Hello there, I'm looking for a mib that can give me the size (number of entries) of the ARP table in a Cat6509. So far I have found how to get the ARP table entries from the atEntry or ipNetToMediaEntry OIDs, but I dont need the individual entries, but the total number of entries.

thanks for any information.

Here's a reasonable start reference, but be warned that the CPU can slapped ugly trapping/setting ARP table MIB objects.

Specifically

?To see a particular MIB's dependencies, use the "View and Download MIBs" tool, which is part of the SNMP Object Navigator on the Cisco IOS MIB Tools page, which is MIB Locator at the following URL:

?For information about trap definitions, alternative size definitions, and null OIDs, go to the following URL:

?For listings of OIDs assigned to MIB objects, go to the following URL:

I don't see anything specific in the BRIDGE-MIB that gives the size of the arp table. The objects show the entries in there, perhaps if you had some script you could look at the values for dot1dTpFdbTable, dot1dStaticTable, and dot1dTpFdbPort to see how many MAC's are in the table.
