be set up to initialize an external (PCMCIA) flash device, copy the entire contents of the 
internal flash device to it, and rename the image as a backup. 

The grstat command options report layer 3 (IP and ICMP) forwarding statistics for the SP 
Switch Router Adapter card and all other media card types excpt HIPPI. Error reporting 
includes the saved source and destination IP addresses of the packet that caused the last error 
of each type reported. 

The grstat l2 command reports many of the Layer 2 (data link layer) statistics currently 
reported by individual media card maint commands for SP Switch Router Adapter, ATM 
OC-3c, HSSI, Ethernet, and SONET OC-3c cards. Examples are included in “Obtaining layer 
2 and 3 statistics - grstat” on page 3-12.  

The grwrite command is crucial on the SP Switch Router because it saves configuration 
changes made in the

 /etc

 directory to a flash device so the changes survive the boot-up 

process. By default, grwrite saves a copy of those files with a newer time stamp than the last 
boot.   

This command mounts an external device so that the device looks like a file system to the 
operating system. Mounting an external device enables various processes to be applied to the 
device. A device is mounted as read only (default) or writable. mountf verifies (fsck) the 
device before doing the mount. When a media card panics, mountf works with grdump to 
write a panic dump out to an external storage device in a PCMCIA slot.  See also umountf. 

   

This command specifies the software version that will load during the next system reboot. The 
general form of the command is 

setver 

release_name

. When setver executes, it verifies 

that the specified 

release_name

 can actually be loaded by checking to see that the 

appropriate release files, start-up scripts, and configuration entities are in place. You see a 
message if these release components are incomplete. See also getver.

This command unmounts a flash device previously mounted by the mountf command. See also 
mountf.   

This command removes a specified release or configuration version from a specified flash 
device.
