[j-nsp] Link aggregation between a 3750 and a M320

[ILTCHEV Alain]

Hello,

I have been reading some past discussions in this mailing and trying things suggested in these discussions but I am not able to setup a LACP link between a Cisco switch and a M320.

In the following, the M320 was in active mode and the 3750 in passive mode.

On the 3750 :
interface GigabitEthernet1/0/49
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 701,702,705
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate
 channel-group 1 mode active
end

interface GigabitEthernet1/0/50
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 701,702,705
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate
 channel-group 1 mode active
end

interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 701,702,705
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate

On the M320 :
chassis {
    aggregated-devices {
        ethernet {
            device-count 16;
        }
...
ge-4/1/4 {
    description "LAG 3750-1 VOIP Port 1";
    gigether-options {
        no-auto-negotiation;
        802.3ad ae4;
    }
}
ge-4/1/5 {
    description "LAG 3750-1 VOIP Port 2";
    gigether-options {
        no-auto-negotiation;
        802.3ad ae4;
    }
}
...
ae4 {
    description "LAG 3750-1 VOIP";
    vlan-tagging;
    aggregated-ether-options {
        no-flow-control;
        link-speed 1g;
        lacp {
            active;
        }
    }
    unit 705 {
        vlan-id 705;
        family inet {
            address X.X.0.148/28 {
                vrrp-group 72 {
                    virtual-address X.X.0.145;
                    priority 2;
                    preempt;
                    accept-data;
                }
            }
        }


I have activated traces on the M320, is anybody able to understand this Juniper log ? ge-4/1/4 and ge-4/1/5 are the ports I am trying to bundle. They keep on switching between the states FAST_PERIODIC and PERIODIC_TX. What's wrong ?
