MacSec on 8300 TX Interface

[DaveBeattie]

I am looking to run "switch-to-switch" MacSec on a 8300-2N2S-4T2X. The hand off is 1GE-TX. I realise that the onboard TX interfaces do not support MacSec, but could I use a TX SPF (GLC-TE or SFP-10G-T-X) in one of the onboard 10G interfaces to make this work? The opposite end of the link will be an identical 8300-2N2S-4T2X router.

MKA is supported on switch-to-host facing links. Host-facing links typically use flexible authentication ordering for handling heterogeneous devices with or without IEEE 802.1x, and can optionally use MKA-based MACsec encryption.

check the limitation here :

Hi BB

Thanks for the response, but I am using a 8300-2N2S-4T2X router not a 8340 and I am looking to do switch-to-switch MacSec, not switch-to-host.
