Hi,
It is very simple,
you can configure eth-port of RAP/ CAP through " wired-ap-profile" and "enet-link-profile" under,
AP-group-->AP-->Ethernet interface 0 port configuration.
Eg :
(Aruba3200) #show ap wired-ap-profile default
Wired AP profile "default"
--------------------------
Parameter Value
--------- -----
Wired AP enable Disabled
Trusted Not Trusted
Forward mode tunnel
Switchport mode access
Access mode VLAN 1
Trunk mode native VLAN 1
Trunk mode allowed VLANs 1-4094
Broadcast Broadcast
(Aruba3200) #show ap enet-link-profile default
AP Ethernet Link profile "default"
----------------------------------
Parameter Value
--------- -----
Speed auto
Duplex auto
802.3az (EEE) Disabled
Power over Ethernet Disabled
Hope you got some clarity on this.
Please feel free to comeback for any further help on this.
Cheers,
Venu Puduchery
