set mac-usergroup group-name attr attribute-name value
Examples
TocreateaMACusergroupcalledmac‐easterswitha3000‐secondSession‐Timeoutvalue,typethe
followingcommand:
RBT-8100# set mac-usergroup mac-easters attr session-timeout 3000
success: change accepted.
ToconfigureaMACuserinthelocaldatabaseandoptionallyaddtheusertoagroup,usethe
followingcommand:
set mac-user mac-addr [group group-name]

RBT-8100# set mac-user 01:0f:03:04:05:06 group macfans
success: change accepted.
Caution: Use this method with care. IEEE 802.11 frames can be forged and can result in
unauthorized network access if MAC authentication is employed.
