RSTP Port Role SNMP parametrs

Igor.Yumatov · ‎08-21-2012

Hello,Dear forum participants,

I apologize if my question does not match this thread.

I want to get RSTP Port Role from CiscoWS-Catalist 3750 48TS-S IOS 12.2(SE)50 using third side SNMP Client.

I have found interesting parameter here: ftp://ftp.cisco.com/pub/mibs/v2/CISCO-STP-EXTENSIONS-MIB.my. it is stpxRSTPPortRoleValue with

1.3.6.1.4.1.9.9.82.1.12.2.1.3 OID

I have successfully done snmpwalk command on my catalist:

snmpwalk -v2c -c <comuniry> <ip> .1.3.6.1.4.1.9.9.82.1.12.2.1.3

SNMPv2-SMI::enterprises.9.9.82.1.12.2.1.3.501.51 = INTEGER: 3

1. What is the meaning of the suffix .500.51, .48.50 etc.?

2. What are the rules of indexing? How can I get RSTPPortRole of the port Fa1/0/1? As I understand STP-EXTENSIONS MIB is not correlate with IF-MIB. http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080157626.shtml#core

Any suggestions

Thanks!

1. The "500" and "48" parts of "500.51, .48.50" appear to be VLAN numbers on your device.

2. There're two books that seem to address this question:

Thanks for yor answer!

The "500" and "48" parts are exactly VLAN indexes. But I'm steel do not understand what is the 2-nd part of the suffix.

When i use "snmpget" for .1.3.6.1.4.1.9.9.82.1.12.2.1.3.500.51 it returns the value but if i use 3-rd-side client ("PowerSNMP Free Manager") it returns "NoSuchInstance".

What is a problem?

Thanks
