Corrective Action
To correct the problem that this alarm identifies, perform the following steps:
Step 1 Follow the procedure to collect system data, which is detailed in the “Collecting System Data for Cisco
TAC” section on page 6-93.
Step 2 Verify that the Ethernet interfaces between the Cisco PGW 2200 Softswitch and the associated media
gateway are working properly.
Note To find information on verifying the proper operation of an Ethernet interface on the
Cisco PGW 2200 Softswitch, see the Sun Microsystems documentation that came with your
system. For information on verifying the proper functioning of an Ethernet interface on the
media gateway, see the documentation for the specific media gateway.
If an element of the Ethernet connection (such as a cable or an Ethernet interface card) is not working
properly, replace it. Otherwise, proceed to Step 3.
Note To find information on removing and replacing an Ethernet interface card on the Cisco PGW
2200 Softswitch, see the Sun Microsystems documentation that came with your system. For
information on removing and replacing an Ethernet interface card on the media gateway, see the
documentation for the specific media gateway.
Step 3 Verify that the near-end and far-end MGCP sessions are operating normally. See the documentation for
the affected media gateway.
