OID for 6500 Switch interface


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.


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,

OID for 6500 Switch interface

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.

OID for 6500 Switch interface

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:
