EM316LNXNM-OT Management Basics
PN 1275005-100 Rev E6 33
5.5.13. Displaying and Saving System Parameters
Use the write terminal command to display the current operating parameters.
Use the write file command to save the current parameters to the configuration file.
These commands display no output besides the prompt.
5.5.14. EM316LNXNM Hot-Swapping
Hot-swap settings are stored on each EM316LNXNM module. Stored startup values are read by the
EM316LNXNM when the module restarts.
The EM316LNXNM may be removed from the chassis during operation and replaced with a spare that
is configured the same as the original. Data flow may be affected while the manager is not available, but
normal Fiber Driver operation resumes when the EM316LNXNM reboots in the system.
Not all line cards or settings support EM316LNXNM hot-swap. Modules that do not support hot-swap
are reconfigured according to the "
startup-config
" file when the NM is booted, which can intertupt
traffic. Settings that do not support EM316LNXNM hot-swap are reloaded from "
startup-config
".
For example, port, slot, and chassis names cannot be read from the hardware, so the EM316LNXNM
software uses these values as stored in the configuration file. To minimize impact from hot-swapping
modules, it is very important to save changes made to the running configuration.
5.5.15. "flush" and "sync"
The flush command forces the system to wait for all previous commands to execute on the target device.
This command assures that the target devices are in the desired operating state. This command is useful
with automated management before any command that requires a known system state.
fiberdriver# flush
The
sync
command forces the system to wait for all previous commands to execute on the target device
AND for the EM316LNXNM-OT to poll the system to update any changes in the status tables. This
command assures that the target devices are in the desired operating state AND that the user interfaces
correctly report the current status including changes. This command is useful with manual management
before any command that reads system status and manageable parameters.
