[alcatel-nsp] Configure Link Aggregation on Alcatel Router 7750

[Nguyen Hoang Nam]

Dear all !

Thanks all for your support. 
I have done it and it works. Below is config on Huawei and ALU
Huawei and ALU have to disable autonegotiate
Huawei only have mode lacp-static
ALU config lacp active or passive / peoridic slow

Huawei:
interface Eth-Trunk1
 ip binding vpn-instance IuB
 ip address 10.0.0.1 255.255.255.252
 mode lacp-static
 lacp timeout slow
#
interface GigabitEthernet1/0/2
 undo shutdown
 eth-trunk 1
#
interface GigabitEthernet1/0/11
 undo shutdown
 eth-trunk 1
#

ALU:
lag 1
        port 1/1/5 
        port 1/1/6 
        lacp active administrative-key 32768 
        lacp-xmit-interval slow
        no shutdown
port 1/1/5
        ethernet
            no autonegotiate
        exit
        no shutdown
port 1/1/6
        ethernet
            no autonegotiate
        exit
        no shutdown
interface LACP
            address 10.0.0.2/30
            port lag-1

Thanks and Best Regards.

Also, you have to set the autonegotiation of the ports to disabled or limited if they are not 10G ports. You can do so as;
config port x/y/z ethernet autonegotiate limited

Otherwise you can't add them to a lag as they must all have the same speed.

Assuming your Huawei supports LACP, something like:

conf lag 1
port 1/1/1
port 1/1/2
lacp active
no shutdown
back
router interface foo
port lag-1

Troubleshoot with:

    sh lag 1 detail
    sh lag 1 statistics
