  • 1.  SRX300 MACsec over Eth

    Posted 07-07-2022 10:56
    I built a Scheme in the lab to test how it works.
    Scheme:
    SRX300@1 ge-0/0/6 < -- utp -- > ge-0/0/6 SRX300#2
    Everything works well
    admin23@SRX-300_lab_98# run show security macsec connections interface ge-0/0/6
    CA name: ca1
    Cipher suite: GCM-AES-128 Encryption: off
    Key server offset: 0 Include SCI: yes
    Replay protect: off Replay window: 0
    Outbound secure channels
    SC Id: 10:39:E9:5E:F7:10/1
    Outgoing packet number: 19
    Secure associations
    AN: 0 Status: inuse Create time: 00:00:17
    Inbound secure channels
    SC Id: 10:39:E9:5F:8C:90/1
    Secure associations
    AN: 0 Status: inuse Create time: 00:00:17

    but as  we install a switch in the middle of L2, and nothing works
    Scheme:
    SRX300@1 ge-0/0/6 <---> QFX5100 <--->ge-0/0/6 SRX300#2
    oro
    SRX300@1 ge-0/0/6 <---> Catalist C3650 <--->ge-0/0/6 SRX300#2

    on the transit switch, we checked various options for the mode of operation of the ports both in the Trunk and in Q-in-Q
    also tried to play with the settings and SRX does not help
    ====
    admin23@SRX-300_lab_98# set security macsec connectivity-association ca1 mka eapol-address ?
    Possible completions:
    <unicast-address> Unicast EAPOL destination address
    pae Port Access Entity group address (01:80:C2:00:00:03)
    provider-bridge Provider Bridge group address (01:80:C2:00:00:00)
    lldp-multicast Link Level Discovery Protocol multicast address (01:80:C2:00:00:0E)

    Who can faced it?
    Or does MAXec not work at all on SRH300?

    Thank you in advance for your feedback and comments.

    Yes it's supported on SRX-3xx and I'm pretty sure you need to configure MACSec on the QFX if you're putting it between the SRX's.

    Yes, but what if the switch is not under our control?
    The main idea is to build a MACSec L2 channel, through.

    And how to make transit, the passage of MACSec in a package through someone else's L2 transport network.

    Are there any other ideas?

    I'm not sure if I need to configure the QFX switch further. In this case, if you join the provider's service, do you need to configure the SP side? I think the main idea is to protect yourself from the service provider? What port mode should I use to pass EAPoL packets?
