OID for 6500 Switch interface

[gururajan]

Hi,

We need to get the MIB /OID information for 6500 series switches. Especially we need to monitor the Gig interface “input & output” traffic rate for every second.

Switch model: WS-C6509-E / SUP 720

We tried the below value but not getting proper output.

MIB:- 1.3.6.1.2.1.2.2.1.10.2

Also we would like to know whether there would be any impact on running the below global command “snmp-server hc poll <in msec>” in 6500 series switch.

Thanks in advance,

Guru

You have the correct MIB IF-MIB which is used to monitor the interfaces for input/output traffic. However the OID you have mentioned is normal 32 bit counter which can wrap up too-fast if the traffic is high. Also, We need to see the delta value of traffic between two timestamp to check the correct input/output traffic.

If the intrefaces are high Capacity or say for interfaces that operate at 650,000,000 bits/second or faster, 64-bit packet and octet counters must be used.  64-bit counters are not supported on 10 Mb Ethernet ports, only 100 Mb Fast-Ethernet and other high speed ports support 64-bit counters.

Thanks for the response.

Please let me know what would be the OID for 64bit counter. We want to poll the 1-Gig port in a 6500 switch.

Thanks again.

Same MIB. Look for the objects beneath ifxEntry:
