[j-nsp] Macsec not working with carrier ethernet link

[james list]

Dear experts,
I have a virtual chassis of ex4300 connected to another vc of ex4300 with 2
x 1 Gbs links provided by two carriers.

Lacp aggregation is up with just one carrier1 link encrypted with macsec,
unfortunately carrier2 is not going to find the problem and macsec packet
are not transported.

I sent them the 802.1ae standard and ethertype to transport but no way.

As far as I could understand they have Huawei devices.

Do you have any suggestion for me to let them verify?

Cheers
James

Ask your Juniper rep for a feature that Cisco calls "WAN MACsec".

Juniper calls it MACsec.

The OP probably needs to make sure the firmware is correct for his platform.
https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/macsec.html

MACsec is also a licensed product.

Make sure the switches were ordered with the EX-QFX-MACSEC-ACC3 license.

Juniper calls it MACsec.

"WAN MACsec" is a slightly modified version that Cisco made in order
to allow it to work over carrier ethernet systems that are underpinned
by protocols that block 802.1x EAPOL and 802.1ae among other L2 PDUs.
It is designed to work when you can't get cooperation from your
carrier.

If your carrier uses L2VPN, L2circuit, or some other type of
point-to-point circuit, plain MACsec should "just work" as long as
their physical port handoff to your MACsec switch is untagged.
However, if they use VPLS or some other p2mp protocol that does MAC
learning, it most likely won't bridge the 802.1x and/or 802.1ae frames
unless a special config is used on the carrier side. Juniper needs to
be configured to tunnel the L2 protocols for example.

Lack of a license won't prevent it from working, at least with 14.x
and 15.x--it will just warn you every time you commit. That might
have changed with 17.x or 18.x.

Hi
Ex4300 is fine with license and as I said one of the two carriers is
working.

As far as I understood the carrier with problems is providing q-in-q
tunneling but I still have to get a confirmation on that.

@Chuck, wan macsec or macsec is not an ieee standard? Juniper doesn't have
any different deployment not standard as far as I know, am I wrong?

Cheers
