Procedure 7-7 (continued)
Testing STM-1/4/16/64/OC-3/12/48/192 protection switching with traffic on 4xFE interfaces of
4xGE + 4xFE circuit pack
Step Action
Testing protection switching on the Ethernet port
7 Determine your next step.
8 Click Submit.
A confirmation page is displayed. After confirming, a success message is
displayed.
9 Connect the test set to a single Ethernet port.
10 Generate a loss of signal condition (LOS) on the working path by
disconnecting the fiber.
Traffic switches from the working to the protection path.
11 Put the fiber back on the working path.
After the WTR time expires, the traffic will switch from protection to working
path.
12 Generate a loss of signal condition (LOS) on the working path by
disconnecting the fiber.
13 Put the fiber back on the working path.
14 During WTR generate a loss of signal condition (LOS) on the protection path
by disconnecting the fiber.
Traffic switches back to work.
Go to step 16.
15 Generate a loss of signal condition (LOS) on the protection path by
disconnecting the fiber.
Traffic switches from the protection to the working path.
16 Put the fiber back on the protection path.
If protection mode is of Then
1+1 MSP/APS go to step 9.
SNCP/UPSR set the reversion mode as non-revertive or
revertive with max WTR time for each VC.VT
in the WAN for the Ethernet port under test.
If the protection type is Then
revertive traffic must switch from protection to working after
the WTR time expires and then go to step 12.
non-revertive go to step 15.
