Switching

I've got two 10Gb/s interfaces running as an Aggregate interface, carrying 3 VLANs. All's working well except that one interface is showing a large number of Framing Errors. I know the cause of Framing Errors but I want to start off investigations by identifying the two remote equipment interfaces to the server Support Team.

 

I've tried every command I can think of but none show (as far as I can see) the MAC Addresses of the two remote interfaces. "show interfaces xe-5/0/2 extensive" only shows the interface Hardware MAC Address and the AE MAC Address.

 

Any help appreciated thanks.

 

Andy.

 

interfaces {
    xe-2/0/2 {
        description "(xe-2/0/2) to server a/1 - member of ae9";
        enable;
        ether-options {
            802.3ad ae9;
        }
    }
    xe-5/0/2 {
        description "(xe-5/0/2) to server a/2 - member of ae9";
        enable;
        ether-options {
            802.3ad ae9;
        }
    }
    ae9 {
        description "ae9 to server a";
        enable;
        aggregated-ether-options {
            lacp {
                active;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                vlan {
                       members [ 2 3 4 ];
                }
            }
        }
    }
}

 

 

Hello Andy,

"show ethernet-switching table ...." should help you.

Please let us know if you have any questions.

Hi Ankit,

 

Thanks for the suggestion but I've already tried an dismissed it;

"show ethernet-switching table interface xe-5/0/2" shows no MAC addresses (expected), and

"show ethernet-switching table interface ae9" shows 5 pages (180+) of MAC addresses, and I don't know how to single out the one I want, or even if it's in the list?

 

Regards

Hello Andy,

I didn't read your question completely, my bad.
If you're looking to find the MAC of the remote end, then this is what you need to do:

1. Issue "show int ae9 extensive". Scroll down to the place where you find the LACP information.
2. Note the MAC address listed against 'partner'. This should be the MAC (LACP-id) of the remote end.

root@FDQDIR> show interfaces NW-NG-0:ae0 extensive | find "LACP info"
LACP info: Role System System Port Port Port
priority identifier priority number key
MLNNG02a:xe-0/0/0.0 Actor 127 f8:c0:01:f9:30:08 127 9 1
MLNNG02a:xe-0/0/0.0 Partner 100 00:00:00:00:00:02 127 2 2 <<<<<<


This won't give you the MAC address of all the member ports of the LAG on the remote side, but you should be able to get the MAC address of the remote-device.

HTH,

Hi ankit,

 

That actually worked a treat:

 

1-re0> show interfaces ae9 extensive | find "LACP info"
    LACP info:        Role     System             System      Port    Port  Port
                             priority          identifier  priority  number   key
      xe-2/0/2.0     Actor        127  00:26:88:8c:f5:f0       127      12    10
      xe-2/0/2.0   Partner      32780  08:17:f4:c5:72:1f     32768      17    75
      xe-5/0/2.0     Actor        127  00:26:88:8c:f5:f0       127      20    10
      xe-5/0/2.0   Partner      32780  08:17:f4:c5:72:1f     32768     145    75

Thanks for your help!

ssh or telnet into the remote device and see what that device is showing both physically and check if there is a different manual configuration

Hi Lyndidon,

 

Thanks for your suggestion however I don't have access to the remote device. I'll contract the third party support team to try to get the MAC address from them, but I really wanted to go to them armed with it so that I could give it to them to assist them with identifying the connection.

I've already asked them to confirm that configuration is identical for the two interfaces.

 

Regards

Andy.
