SNMP monitoring of RPS2300 power system on 3750E

Unanswered Question

Hi there.

I am trying to monitor RPS2300 redundant power system connected to 3750E stack.

Using console connection with " show env " command i can see all the information about the RPS2300 redundant power system as follows:

**********************************************

SW Status RPS Name RPS Serial# RPS Port#

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

1 Active CiscoRPS CAT1131VG40 1

2 Active CiscoRPS CAT1131VG40 2

3 Active CiscoRPS CAT1131VG40 3

RPS Name: CiscoRPS

State: Active

PID: PWR-RPS2300

Serial#: CAT1131VG40

Fan: Good

Temperature: Green

RPS Power Supply A: Present

PID : C3K-PWR-750WAC

Serial# : DTN1126E0C9

System Power : Good

PoE Power : Good

Watts : 300/450 (System/PoE)

RPS Power Supply B: Present

PID : C3K-PWR-750WAC

Serial# : DTN1126E0CG

System Power : Good

PoE Power : Good

Watts : 300/450 (System/PoE)

DCOut State Connected Priority BackingUp WillBackup Portname SW#

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

1 Active Yes 6 No Yes c3750_stack01 1

2 Active Yes 6 No Yes c3750_stack01 -

3 Active Yes 6 No Yes c3750_stack01 -

4 Active Yes 6 No Yes c3750_stack02 1

5 Active No 6 No Yes <> -

**********************************************

But i could not monitor any value listed in console using SNMP. I could not find any MIB table regarding RPS2300 health. When walked on MIB file CISCO-ENVMON-MIB, it even looks, no RPS is connected:

**********************************************

ciscoEnvMonSupplyStatusTable(5)

ciscoEnvMonSupplyStatusEntry(1)

ciscoEnvMonSupplyStatusDescr(2)

1059 Sw1, PS1 Normal, RPS NotExist

2060 Sw2, PS1 Normal, RPS NotExist

3059 Sw3, PS1 Normal, RPS NotExist

ciscoEnvMonSupplyState(3)

1059 normal (1)

2060 normal (1)

3059 normal (1)

ciscoEnvMonSupplySource(4)

1059 ac (2)

2060 ac (2)

3059 ac (2)

**********************************************

Is there a way or a new MIB to monitor RPS2300 via SNMP ???

Thanks in advance...

Regards..

Bulent.

I have this problem too.

There is a syslog message at ALERT level when the internal power supply is removed or is detected as being faulty.

If you have a 3560e connected to RPS2300, you may try "power supply off" and then see the syslog message. Also, "sh env power" should indicate the status of the power supply and "sh env rps" will inform if the RPS is backing up the switch.

Did you try to walk the CISCO-ENTITY-FRU-CONTROL-MIB ?

I am wondering if it could be reported correctly from this mib, it would be good if somebody could test it.

I ran into the same issue on a 2960S and was able to figure it out. I was able to monitor using an SNMP query using walk type, get next, OID = .1.3.6.1.4.1.9.9.13.1.5.1.2.

The OID for switch I was testing ended up being .1.3.6.1.4.1.9.9.13.1.5.1.2.1006. I am not sure if the ending value is persistent or will change after a reboot. I know on the 3560-X the ending value may change after a reboot when monitoring two modular power supplies.

Below is the possible SNMP output I was able to detect.

Switch Internal Power Supply Status

Redundant Power Supply Status

SNMP Output =

Sw1, PS1 Normal, RPS Normal

Sw1, PS1 Normal, RPS unknown

Management Commands

Using Cisco 2960S, I am assuming similar function on 3560/3750 E or X routers/switches

show env power

Internal Power Supply Status

show env rps

Redundant Power Supply Status

power rps 1 port 1 mode standby

Place RPS into standby after power has been restored to internal power supply. No reboot required

power rps 1 port 1 mode active

Place RPS into active (ready) state so it is able to supply power in the event of another failure. No reboot required

Using Cisco 2960, I am assuming similar function on all other non E or X routers/switches

power rps 1 port 1 mode standby

Place RPS into standby after power has been restored to internal power supply. Will automatically reboot switch

power rps 1 port 1 mode active

Place RPS into active (ready) state so it is able to supply power in the event of another failure. No reboot required
