This will make your wireless link preferred, if the link fails the OSPF adjacency will fail and routing will fallback to the other link.

You should ideally have some /32 loopback interfaces so the router will use this as the OSPF RID, or manually set the RID under the OSPF process.

More discussion about this you can see http://www.router-switch.com/forum/showTopicDetails/11/490

If you have two SUP's this one will be in standby mode.

Hi, if you installed a Supervisor 6L-E 10GE (X2) in the new 4506-E and you want to use the two 10GE uplinks as Gigabit, you need to type in the following config lines:

hw-module module 1 port-group 1 select gigabitethernet
hw-module module 1 port-group 2 select gigabitethernet

Please make sure you have only one supervisor module installed on your switch or else pull out the backup sup module and do this activity .

In the last step of reset it will ask to save the config.

do you wish to save this configuration? y/n [n]: y
You must reset or power cycle for new configuration to take effect

do not forget to type in y there.

Please see Cisco's page at http://www.cisco.com/en/US/products/hw/routers/ps5199/products_password_recovery09186a0080093e12.shtml
for step by step details and more in depth instruction.

1. Reboot
2. Press the "break" button on your keyboard within 60 seconds of the power-up to put the router into ROMMON mode.
3. confreg 0x2142
4. reset
5. type, "no" when prompted to enter the initial configuration dialog.
6. enable
7. copy startup-config running-config
8. conf t
9. enable secret <password>
11. config-register 0x2102
12. reboot again

shut down the port and then no shut the port.

Hi
How can we help?

use software advisor in Cisco website to verify it.just follow the process.

console to it and show diag and see whether it detectable or not.

hope this help.
