CRS-1 plaspa port and jacket slot

Answered Question
Apr 5th, 2012

Hi Expert,

I need to replace SPA card to resolve the error

%L2-PLIM_ASIC-4-HW_WARNING : plaspa instance 0: (plaspa port 2 jacket slot 0) RSI Spi Error was reported

The plaspa port 2 jacket slot 0 would be SPA slot 0 (0/0/0), correct? 

NAME: "0/PL0/*", DESCR: "Cisco Carrier Routing System SPA Interface Processor Card"

PID: CRS1-SIP-800      , VID: V04

NAME: "0/0/0", DESCR: "2-port OC48/STM16 POS/RPR Shared Port Adapter"

PID: SPA-2XOC48POS/RPR , VID: V02

NAME: "POS0/0/0/0", DESCR: "OC48 SR/STM16 I-16"

PID: SFP-OC48-SR         , VID: V01 ,

NAME: "0/0/2", DESCR: "2-port OC48/STM16 POS/RPR Shared Port Adapter"

PID: SPA-2XOC48POS/RPR , VID: V02

Thank you for all replies

I have this problem too.

If the power we get is too low, replacement won’t fix it either.

  1. Use a power meter to confirm the power level you receive.
  2. Find out the power budged for this cable. It should have been provided by your carrier.
  3. Verify with the carrier that is their Tx power level

Hi Roger,

RSI Spi Error errors may appear when there are SONET errors on the POS interface. You may want to verify the line first.

I encounter the RSI SPI error incrementing if i issue show controller plim asic plasspa error location 0/0/CPU0

RSI SPI error              5020800

RSI SPI error              5020881

RSI SPI error              5020897

RSI SPI error              5020902

akiritch Thu, 04/05/2012 - 03:25

Yes, it can be failed SPA, but a probability is higher that there are just SONET errors.

Look at ‘show controller SONET 0/0/0/x’ and verify all the interfaces for any increasing errors.

I didn't see any errors on SONET interface from command show controller SONET 0/0/0/0 and 0/0/0/1

these sesion shows errors:

  LOF = 38         LOS    = 20                           BIP(B1) = 2761538

  AIS = 4          RDI    = 63         FEBE = 21712298   BIP(B2) = 6871279

verfiy if they are increasing.

Rojer-bkk Thu, 04/05/2012 - 03:48

Thanks. I found BIP(B1), B2, B3 value increasing

  BIP(B1) = 2761803 BIP(B2) = 6871541 BIP(B3) = 4673494

  BIP(B1) = 2761806 BIP(B2) = 6871544 BIP(B3) = 4673497
  BIP(B1) = 2761823 BIP(B2) = 6871561 BIP(B3) = 4673514

  BIP(B1) = 2761823 BIP(B2) = 6871561 BIP(B3) = 4673546

Anway, the error messages was reported almost every hour

RSI errors are not 1:1 linked to SONET errors, but errors on the line can cause some RSI errors to appear.

We have B1 errors already, they show we have a problem between this interface and the first connected carrier device. That has to be addressed first.

akiritch Thu, 04/05/2012 - 04:35

There is a small possibility that the physical B1 errors are caused by failed SPA or XFP, but I would not start with that as probability is low.

A simple test,

  1. schedule a maintenance window
  2. put a physical loopback on the SONET 0/0/0/0 (connecting Rx with Tx by one cable).
  3. Use ‘sh controller SONET 0/0/0/0’ to monitor for B1 errors. We should not see any. And if we don’t when this SPA is OK

btw, which exactly XFP do you use? I see we have Rx power -24.9 dBm. It may be too low for some XFPs.

Regards,

/A

Rojer-bkk Thu, 04/05/2012 - 05:02

The error could be from SPA card or SPF even carrier devices. If we can prove the SPA card is ok so we have to check SFP POS0/0/0/0 for next step?

Hello Alexei,

The problem can be solved with you advised. Many thanks!!!

Rojer-bkk Mon, 04/23/2012 - 05:50

Can i monitor Tx/Rx power via SNMP? if yes, please let me know MIB to me? Thanks

akiritch Mon, 04/23/2012 - 12:02

That is not implemented on CRS.

Hello Alexei

What is plaspa port ? can you please give me an idea for it ?

thanks

akiritch Sat, 05/05/2012 - 13:05

PLA stands for PLIM LINK ASIC. PLASPA used on the SIP card for CRS and it is the interface controller for the PLIM.

In the ingress direction it takes all the traffic coming from the different ports on the PLIM and places them into virtual queues.

In the egress direction it takes all the traffic from the EgressQ ASIC buffers it and then transmits it to the appropriate egress port.
