When a media card does not boot after grdiag
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
“Switch receive error” can indicate hardware problem
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'

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.
