Click on the chassis (Engine) that is displaying the link alert message.
e.
Scroll down to the stacking information. See the following example.
Example of the stacking data
Switch slot 0 is the left side of the Engine, and switch slot 1 is the right side of the Engine.
Look in the 10 Gb Port Map column:
-
If “
0X1
” is displayed, the port is up.
-
If “
0X0
” is displayed the port is down.
So if the right side of a Engine is reporting a link alert message, and “0X1” is displayed for
Switch slot 1. The port is up, and this is a fake link alert. If the right side of a Engine is
reporting a link alert message, and “0X0” is displayed for Switch slot 1. The port is down,
and this is a real link alert.
Restart All Procedure
The following procedure is a two part procedure used to correctly and safely restart all of the
Engines, as well as power cycling all of the Engines.
Part 1 gets the Engine correctly up and running, however it triggers the fake link alert problem.
You can to use the ISIS after you have completed part 1, however the link alerts you see are fake.
Part 2 corrects the fake link alert messages. When using part 2 of the procedure, wait until it is
complete before you use the ISIS.
Part 1 — Restart or power cycle all of the Engines:
1. Telnet into the connecting Ethernet switches (Cisco 4900’s) and use the “shut” command to
shut down all ports that connect to the ISIS stack (Currently there is no reason to shut down
the ports that connect one 4900 to the another 4900). The act of shutting down the ports
connected to the ISIS causes a link alert message to be displayed. This is a real alert message
because the ports have been shut down.
2. Restart all the Engines (or power cycle them). Allow all Engines to come up.
3. Go to the ISIS Switch Blade Agent page, and every few seconds select the Overview display.
This updates the Overview display with the latest information.
4. Watch the request busy entry, and wait for it to go to “No.”
5. Watch the Request state column, and wait for every state to go to “Done.”
