AiroNet Transmit Key

[Ian1Tek]

Lately, I came across an old setup with two CISCO AiroNet Wireless Bridge. It is a simple one to one bridge to carry the traffic across two buildings.

One station is set up as root, the other is non-root.
It carries two vlans across the bridge.

I found out that is the keycode <transmit key> is different in root and non-root device.

Should the keycode be the same for the same vlan ? Are they simply random keycode or there are some ways to generate the keycode pairs properly.
