AIR 1242AG Root Bridge Radio

Question

Hi,
Can the radio of the AIronet 1242-AG in root bridge mode shut down itself when the Ethernet link is down like in AP mode (
station role root access point fallback track d0 shutdown )?
I've 2 AIR 1242-AG as root bridge for connecting a few 1242-AG as non-root bridge, in case the ethernet of the root bridge is down, the non root bridge connected to it will lost its connection to the backbone network. If the root bridge radio can shutdown automatically, the non root bridge can associate to the other root bridge, then the backbone network.
Thanks.

Answer 1

Hi,
According to the CLI on-line help (listed below), the station-role root fallback configure the 'Root AP action if Ethernet port fails'. Would like to know if it also support Root Bridge mode such that the radio will be shut down when the Ethernet fails?
As I don't have a pair of 1242 on hand, I cannot test it out.
Please help. Thank you.
