[j-nsp] [c-nsp] LAG Problem Cisco/Juniper

[Bill Blackford]

I'm not an expert on this subject, but I do notice you don't have a 'chassis' stanza. Also, each physical interface should probably have the spped forced as well. The flowing works for my LAGs. Obviously, I'm using port-mode trunk on mine

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





ge-0/0/46 {
    ether-options {
        speed {
            1g;
        }
        802.3ad ae0;
    }
}
ge-0/0/47 {
    ether-options {
        speed {
            1g;
        }
        802.3ad ae0;






ae0 {               
    aggregated-ether-options {
        lacp {      
            active; 
        }           
    }               
    unit 0 {        
        family ethernet-switching {
            port-mode trunk;
            vlan {  
                members all;
            }       
            native-vlan-id 1;

Hey folks.

 

I'm cross posting this so apologies if you are both lists.

 

Trying to get a LAG group up between a Juniper EX4200 switch and a Cisco
7606 using a pair of GigE's - rush job etc..  can't get the group to come up
and missing something obvious ;)

 

Cisco:

 

interface GigabitEthernet3/25

 description ----------

 switchport

 switchport access vlan 56

 switchport mode access

 no cdp enable

 channel-protocol lacp

 channel-group 2 mode active

 

interface GigabitEthernet3/37

 description --------------

 switchport

 switchport access vlan 56

 switchport mode access

 no cdp enable

 channel-protocol lacp

 channel-group 2 mode active

 

interface Port-channel2

 description --------------

 switchport

 switchport access vlan 56

 switchport mode access

end

 

 

Juniper Side:

 

    ge-0/0/35 {

        description xxxxx-1;

        ether-options {

            802.3ad ae0;

        }

 

 

    ge-0/0/47 {

        description xxxxxx-2;

        ether-options {

            802.3ad ae0;

        }

 

 

    ae0 {

aggregated-ether-options {

    minimum-links 1;

    link-speed 1g;

    lacp {

        passive;

    }

}

unit 0 {

    family ethernet-switching {

        port-mode access;

        vlan {

            members xxxxxx;

        }

    }

}
