Stack SNMP for 3750 switches

[CSCO10583165]

Hi all,

We want manage via SNMP some 3750 in stack.

We have 2 doubts:

1) What is the sequence of OID to the interfaces in the different boxes in the stack?

Example:

interfaces.ifTable.ifEntry.ifInOctets.10047 fa1/0/47 in the first stack.

interfaces.ifTable.ifEntry.ifInOctets.10547 fa1/0/47 in second stack.

If we install other 3750, the third stack will have 500 more in the OID too?

2) Is it possible obtain via SNMP the number of switches in the stack?

Regards,

Sergio.

1) In an NMS, the IF-MIB generates and assigns an interface index (ifIndex) object value that is a unique number greater than zero to identify a physical or a logical interface. When the switch reboots or the switch software is upgraded, the switch uses this same value for the interface. For example, if the switch assigns a port 2 an ifIndex value of 10003, this value is the same after the switch reboots.
