I am trying to make MACSec work between a pair of Nexus 7702's running 8.3.1
I have configured the macsec policy and key chain
But when I go to apply to the interface I get an error
key chain K1 macsec
key 01
key-octet-string 7 075f701e1d5d4c53404a520d052829272b63647040534355560e00595
2560c001b cryptographic-algorithm AES_128_CMAC
macsec policy TEST
cipher-suite GCM-AES-128
key-server-priority 200
conf-offset CONF-OFFSET-30
VDC_CORE_01(config-if)# macsec keychain K1
ERROR: Interface Ethernet1/47 does not support MKA MACSec.
VDC_CORE_01(config-if)# sh run int e1/47
Any ideas?
