Alarm Troubleshooting
A Manual command switches traffic if the path has an error rate less than the signal degrade. A Manual
Note
switch is preempted by a Force switch.
Step 1
In node view, click the Maintenance > Protection tabs.
Step 2
In the Protection Groups area, select the protection group with the port you want to switch.
In the Selected Groups area, select the port belonging to the card you are replacing. You can carry out
Step 3
this command for the working or protect port. For example, if you need to replace the card with the
protect/standby port, click this port.
In the Switch Commands area, click Manual.
Step 4
Click Yes in the Confirm Force Operation dialog box.
Step 5
If the switch is successful, the group now says "Manual to working" in the Selected Groups area.
Step 6
Clear a 1+1 Force or Manual Switch Command
If the 1+1 protection group is configured as revertive, clearing a Force switch to protect (or working)
Note
moves traffic back to the working port. In revertive operation, the traffic always switches back to
working. There is no revert to the protect. If ports are not configured as revertive, clearing a Force switch
to protect does not move traffic back.
Note
If the Force Switch was user-initiated, the reversion occurs immediately when the clear command is
issued. The five-minute WTR period is not needed in this case. If the Force was system-initiated, allow
the five-minute waiting period (during WTR) before the reversion occurs.
In node view, click the Maintenance > Protection tabs.
Step 1
In the Protection Groups area, choose the protection group containing the port you want to clear.
Step 2
In the Selected Group area, choose the port you want to clear.
Step 3
In the Switching Commands area, click Clear.
Step 4
Step 5
Click Yes in the Confirmation Dialog box.
The Force switch is cleared. Traffic immediately reverts to the working port if the group was configured
for revertive switching.
Initiate a Lock-On Command
For 1:1 and 1:N electrical protection groups, working or protect cards can be placed in the Lock On state.
Note
For a 1+1 optical protection group, only the working port can be placed in the Lock On state.
