Switching

Hi,

I've configured a standalone EX2300 with an ae interface, which connects to an EX-series virtual chassis.

This switch only has one ae uplink (with two interfaces), no other uplinks to any other switches.

When I bring up the interface it sends 3 or 4 BPDU's, and then stops. It receives plenty of BPDU's, but won't send them.

Any ideas?

xe-0/1/0 and 0/1/1:

ether-options {
    802.3ad ae0;
}

chassis config:

aggregated-devices {
    ethernet {
        device-count 2;
    }
}

ae0:

description Uplink;
unit 0 {
    family ethernet-switching {
        interface-mode trunk;
        vlan {
            members all;
        }
    }
}

BPDU's:

Interface     BPDUs       BPDUs        Next BPDU       TCs        Proposal    Agreement
              Sent        Received     Transmission    Tx/Rx      Tx/Rx       Tx/Rx
ae0              4          34             0           0/0         0/0         4/0

It appears I've been silly...

This is an RSTP root port, and root ports do not continually send BPDU's like a designated port will.

So, there's no issue after all!
