[j-nsp] macsec

[james list]

Dear experts,

I’m trying to get working macsec between Cisco 3850 and Juniper EX4300
without success.

Here the config:

Cisco 3850

key chain test macsec

 key 123ABC

   cryptographic-algorithm aes-128-cmac

!

interface TenGigabitEthernet1/0/21

 switchport access vlan 10

 switchport mode access

 cts manual

  policy static sgt 4

  sap pmk 0000000000000000000000000000000000000000000000000000000000123ABC
mode-list gcm-encrypt

end

EX4300

set security macsec connectivity-association test1 security-mode static-cak

set security macsec connectivity-association test1 mka key-server-priority 0

set security macsec connectivity-association test1 replay-protect
replay-window-size 5

set security macsec connectivity-association test1 pre-shared-key ckn 123ABC

set security macsec connectivity-association test1 pre-shared-key cak
"$9$-mVb2oAUHkP4oz11Cu0"

set security macsec interfaces ge-0/0/21 connectivity-association test1



It remains UP on Juniper side and “not connected” on Cisco side, if the
macsec is removed everything is UP.

Anyone has already tried and can provide any hint/example config ?



Thanks in advance, cheers,

James
