Wierd

[Edgar Khachatrian]

OK...

I have discovered something extremely weird, if anyone can help me with this I would really appreciate it.

So I have a wireless bridge set-up with two Cisco Aironet AP's ( 3500 and 1200 ), on the 5Ghz radio interface.

All 2.4Ghz (Dot11Radio 0) interfaces are disables (shutdown), on both Root and Non-Root Bridges.

So the weird thing is when I do a "sho dot11 ass all", on the Root Bridge, besides showing the actual assosiaction from the non-root bridge it also shows this,

"

Address           : 108c.cf10.4090     Name             : NONE

IP Address        : 0.0.0.0

Gateway Address   : 0.0.0.0

Netmask Address   : 0.0.0.0            Interface        : Dot11Radio 1

Device            : Br-client          Software Version : NONE

CCX Version       : NONE               Client MFP       : Off

State             : Assoc              Parent           : 0817.35f4.dfc0

SSID              : SOCHiBridge

VLAN              : 0

Hops to Infra     : 0

Clients Associated: 0                  Repeaters associated: 0"

well the address, "108c.cf10.4090" belongs to the 2.4Ghz on the non-root bridge....Wierd!!!

Why would this happen???

Also since the 2.4Ghz is disabled on both Root and Non-root, why ohhh why would it create and active a "Virtual-Dot11Radio0" interface...?

why not "Virtual-Dot11Radio1"????

Thanks in Advance...

If you enabled the 2.4 GHz radios,  would it then change to 108c.cf10.409F?

I would be curious.  

Cisco assigns BSSIDS per radio and not AP

2.4 side increments up to F  while 5 side starts at F and decrements down to 0

So does the output of "#show int dot11radio 1" reflect a different hardware address?  It appears it's using the MAC of the BVI for the parent info.  BVI1 would be the same address for both 2.4 and 5, only the BSSID should be different.  Maybe that assumption is incorrect, but i'm curious the output you get on the command for radio 1/5GHz.
