Media card reset and checkout
This section describes tools available from the system software to check out newly-installed
media cards. These tools are to be used on the GRF router
•
The ping command tests whether a media card can process and return a message.
•
The grcard command tells you the operating state of an installed media card.
•
The grreset command allows you to reset all or an individual media card.
Verify media card operation using ping
Check media card viability using the ping command. This UNIX command is modified to
support GRF board components. This use of ping only tests internal communication between
the GRF control board and the specified media card. It does not test message routing between
media cards or communication between media cards and external devices.
Note:
The ping command can be used without disturbing normal GRF operations.
The ping -P grid <slot number> command sends a message to a specified media card asking
the media card to respond back with another message.

Enter a ping command. Specify the appropriate media card by its chassis slot number.
For example, to act on the media card in slot 3, enter:
# ping -P grid 3
This is what you see when the media card responds:
68 bytes from 0:0x3:0: time=0.293 ms
68 bytes from 0:0x3:0: time=0.251 ms
68 bytes from 0:0x3:0: time=0.288 ms

Do a C to stop the ping and view ping statistics:
-- 2 GRID ECHO Statistics --
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.969/1.060/1.172 ms
To act on the control board, enter:
# ping -P grid 66
Refer to the GRF Reference Guide for a description of the ping command.
