asic

Unanswered Question
Jan 8th, 2008

hi,

looking for snmp or other way to check the utilization of asic on 6500 module.

i.e - if i am over utilized 4 giga ports on blocking module such as 6148, i would like to monitor it or to notify it (maybe with trap) when it passed the 1G barrier.

thanks

You may have come across this document already:

http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00801751d7.shtml#ASIC

It looks to me that the most feasible approach is to write a custom script (with the "expect" scripting language, for example) to keep tabs on the buffer overruns (or qos3Outlost on Native IOS) from the CLI. What the Cisco link doesn't say is, on the CatOS at least, you'd need [to write the script] to determine what "PORT" ASIC each module is using with "show asic slot #" in enable mode. For example:

CatOSCat6500 (enable) show asic slot 2

Forwarding engine version : 3

Shortcut engine version : 1

Central rewrite engine version : 0

Asic Name Count Major Version Minor Version Asic Type

-------------------- ----- ------------- ------------- ---------------------

pinnacle 1 2 0 PORT

medusa 1 2 0 FABRIC-BUS

titan 1 0 1 REPLICATION

But sometimes, it doesn't show which ASIC is what:

Module in slot 2 has 3 type(s) of ASICs

ASIC Name Count Version

PINNACLE 1 (2.0)

MEDUSA 1 (2.0)

TITAN 1 (0.1)

Then you look for non-zero values in the following output:

CatOSCat6500 (enable) show asicreg errcounters

NativeIOSCat6500# show counters interface gigabitEthernet | include qos3Outlost"
