Hello Keith,

use sh proc mem to see what processes are using the memory.

Have you got any routing protocol running on it ?

Security measures like Dynamic ARP inspection, DHCP snooping and so on ?

802.1X ?

If the switch is used as a simple L2 switch with no additional features it should be fine and quiet about memory.

If this is the case I would think of an IOS upgrade to 12.2(46)SE or 12.2(44)SE.

Hope to help

We're using the switch as L3 and running the following on the:



AAA - Radius/Tacacs

L3 Portchannels



And that's pretty much what we running on the box.

Perhaps i should ugrade to later IOS.

Hello Keith,

how many OSPF routes are in the db ?


sh ip ospf summary

if in the order of thousands you should think to put it in an OSPF stub area but you likely have already it in a stub area.

if you like you can post the sh proc mem to see what are the processes that uses more memory.

Copy it to a text file with .csv extension import it in a spreadsheet and order based on memory usage

(I don't rembember is a sh proc mem sorted option exists)

Hope to help

My area is stub and I have less than 100 routes in the db. See the top memory users on the switch below,

HRPC qos request

HQM Stack Proces

RedEarth Tx Mana

Hulc LED Process



And just for interest sake , there is no command sh ip ospf summary, but sh ip ospf summary-address.

Hello Keith,

sorry for the mistake

the right command should be

sh ip ospf database summary

However, OSPF is not an issue in your scenario.

I would go for an IOS upgrade

Hope to help
