I don't have one of the switches to connect to in front of me but I found the downloadable mibs for the 4400 and I'm sure the other are in there also. It's hard to believe how much is covered by some of he mibs these days. Digging through it all to find what you're looking for can be needle in a haystack almost.

I believe you can monitor the 3Com 4400 switches with the OID 1.3.6.1.4.1.43.10.27.1.1.1.7

try to walk the mib there

tsiu

thank you.

i think the same oid gives me the cpuusage for 4226 3870 and 4929 3com switches. is my assumption correct?

and the oid for memory usage?

the oid you provide me points (stackUnitState)

1.3.6.1.4.1.43.10.27.1.1.1.7.

is there any way to find out which oid polls memory and which polls cpu. i cannot find info at 3com website.

Thanks in advance

Try some of these:

Cpu OID - .1.3.6.1.4.1.43.45.1.6.1.1.1.2 - The overall CPU busy percentage in the last 5 second period.
Memory OID:
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.2 - Indicates the total size of the memory module which is on the managed object.
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.3 - Indicates the free size of the memory
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.4 - Indicates the used size of the raw slice memory
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.5 - The largest free size of the contiguous area in the memory. The unit is byte.
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.6 - The times of memory allocation failures
.1.3.6.1.4.1.43.45.1.6.1.2.1.1.7 - The times of memory allocation failures due to no free memory.
