Checking for hardware problems - grdiag

SP Switch Router Adapter Guide - 1.4 Update 2

 

3-23

For grdiag to run, a card must be able to boot. If the grcard display does not include the slot in 
which the problem card resides, grdiag cannot operate on that card.

For example, grdiag cannot run diagnostics on the card in slot 1 of this router:

# grcard

 0      ATM_OC3_V2     running

 2      DEV1_V1        running

 3      HSSI_V1        running

The 

Switch Receive Error

 means a media card has received a packet from the SP Switch 

Router backplane switch that contains errors. Here are examples of such packets sent by the 
card in slot 3 and received by the Ethernet card in slot 4:

dst=0:0x40:16, src=0:0x3:0, type=GRID:  hwtype=ETHER_V1 cmd=MSGP 

'[RX] Switch Recieve Error.  Status: 0xb04\r\n'

An occasional occurrence of this error in the 

gr.console

 log is part of normal operations and 

can safely be ignored.

However, if clusters of many such errors are reported, it is likely that there is a problem with 
the switch hardware in either the sending media card or the receiving media card. A card may 
need to be replaced. If you see the message repeated many times, please contact Customer 
Service.
