SNMP monitoring of stack RPS

[Petr Nyvlt]

Hello everybody,

I need to monitor status of RPS of stack switches.

I have found this OID  chassisPs2Status 1.3.6.1.4.1.9.5.1.2.7

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.5.1.2.7

It returns 2 when OK, 4 in case of failure, but it works only for master switch in stack. It doesn´t change when RPS of member switch fail.

SW  Status          RPS Name          RPS Serial#  RPS Port#

--  -------------   ----------------  -----------  ---------

1   Active          <>

2   Standby         <>

It still return 2 as OK

Is there some OID for stack members? In case of stack of 9 switches they cannot be backed up by one RPS and we need to monitor it's RPS status.

Hi Petr,

When monitoring the status of the PS's on the master you should be able to get the
information about the slaves as well.

You can also use the CISCO-ENVMON-MIB which contain two OIDs to fulfill your purpose:

1)  .1.3.6.1.4.1.9.9.13.1.5

2)  .1.3.6.1.4.1.9.9.13.1.5.1.4

Thanks-

Hi Ahmad,

thank you for you quick response. I have checked the suggested MIB in lab.

There is stack of 2 switches C3750. Master is OK, member has faulty RPS.

It displays faulty RPS only in string description.

Is that the only  way how to find that it's faulty?

Hi Petr,

You can use these OID's for other stack memebers .These are the olny OID's available to get the results.

1.3.6.1.4.1.9.9.13.1.5.1.3  >> to know the state of power supply

1.3.6.1.4.1.9.9.13.1.5.1.2  >>  for textual description 

You can use this table (ciscoEnvMonSupplyStatusTable -

1.3.6.1.4.1.9.9.13.1.5) to know all details of power supply 

Thanks-
Afroz

Hi Ahmad,

To summary,

There is only textual description

1.3.6.1.4.1.9.9.13.1.5.2 that shows status of RPS of member switches.

OID 1.3.6.1.4.1.9.5.1.2.7 can be used only for monitoring of stack master's RPS. I can't imagine how to address each stack member with own address to ask for this OID...
