[j-nsp] LACP / 802.3ad interop with Cisco 6500

[Andrew.McConnell at sungard.com]

Hello,

Has anyone successfully configured LACP (802.3ad) between Juniper M-series 
routers and Cisco 6500 series switches?  My relevant configuration is 
below.  Previous threads in this list indicate that others have 
experienced similar issues but no resolution was noted.

I was expecting to see an interface "ae0" in the output of "show 
interfaces terse" to aid in my troubleshooting but do not.

== Juniper M40 (6.4R1.6)==

ae0 {
    vlan-tagging;
    aggregated-ether-options {
        lacp {
            active;
        }
    }
}
ge-0/0/0 {
    gigether-options {
        802.3ad ae0;
    }
}
ge-0/2/0 {
    gigether-options {
        802.3ad ae0;
    }
}
