WIRELESS - How to Check DATA RATE WIRELESS CLIENT

 How to Check DATA RATE  WIRELESS CLIENT

Some time we face a issue where we need to know the DATA RATE for CLIENT which is associated with Access Point - DATA rate value explaination below

SHOW CLIENT DETAILS <MAC>

u  Current Rate..................................... m9 ss2

u  Which means that the client is using the MCS 9 (m9) index on 2 spatial streams (ss2)

u  From the "show client detail <MAC>" command, it is not possible to see if the client is connected on 20/40/80 MHz channel bonding.

u  This can be done directly on the AP:

u  Wave2 AP example:

u  AIR-AP3802I-E-K9#show controllers dot11Radio 1 client 94:65:2D:D4:8C:D6

u  In case of Wave1 AP you need to run the debugs:
