Halting Packet Transfer Between Slots
When you reset a slot containing a processor (FRE or ACE) module, the router
automatically halts packet transfer between the resetting slot and the other slots in
the router. Packet transfer automatically resumes after the slot is operational again.
When you hot-swap a FRE module, the router also automatically halts and then
resumes packet transfer.
When you hot-swap a Bay Networks ACE module, be sure to enter the following
Technician Interface command first, where
<slot_no.> is the number of the slot
containing the ACE you are going to hot-swap:
stop
<slot_no.>
This command halts packet transfer between the slot you specify in the <slot_no.>
option and the other slots in the router. When you insert another ACE module in
the slot, ACE diagnostics automatically start, the software resumes on the slot,
and the other slots are informed that the slot in question is available for packet
transfer.
Verifying and Upgrading Software
The Technician Interface provides the following commands for verifying and
upgrading executable software:
•The
readexe
command calculates file header and image checksums on
executable files on the file system, verifies that the checksums match those
within the files, and displays the results and all file header information. Use
this command to validate executable files before upgrading.
•The
prom -w
command erases the PROM and copies the contents of the
PROM update file to the PROM. Use this command to update (write) a PROM
with new software.
•The
prom -v
command compares the contents of a PROM file on the file
system to the contents of a PROM. Use this command to verify that the
software installed in the file system matches the software loaded on a PROM.
