Config Example LAG between C3 stack and summit X450-g2 MLAG

[Rien_Maurik]

Hello All

Does anyone have a good and stable config example for me to set up a lag of 4Gb (4x1Gb) between a C3 stack of 4 units and a MLag setup of 2 Summit X450-G2 switches?

The Mlag peering config of the X450-G2 is al ready running and stable, but I'm struggling with setting up a stable LAG with the C3 stack.

As long as spanning tree is not enabled on the X450-G2s, STP config on the C3 should not be a problem.

Hi,

the VLAN config for the C3 is missing the LAG port lag.0.2. It should look as follows:

set vlan egress 1 ge.1.48; ge.2.48;ge.3.26;ge.4.48;lag.0.2 untaggedset vlan egress 10 ge.1.48; ge.2.48;ge.3.26;ge.4.48;lag.0.2 taggedset vlan egress 20 ge.1.48; ge.2.48;ge.3.26;ge.4.48;lag.0.2 taggedset vlan egress 30 ge.1.48; ge.2.48;ge.3.26;ge.4.48;lag.0.2 taggedset vlan egress 666 ge.1.48; ge.2.48;ge.3.26;ge.4.48;lag.0.2 tagged
You should verify the link aggregation function using "show sharing" on X450-G2 and "show port status lag.0.*" commands on the C3. On the C3, the physical ports have to show up as "dormant" in the "show port status" output.

You should verify the VLAN configuration for the LAG on the C3 using "show port egress lag.0.2".

Here is an example of a static lag on a C3
Note:
You can do this with one command and the command configures 6 commands

(su)->set lacp static lag.0.6 key 12345 ge.1.47-48

Issuing :
set lacp static lag.0.6
set lacp aadminkey lag.0.6 12345
set port lacp port ge.1.47 aadminkey 12345
set port lacp port ge.1.47 disable
set port lacp port ge.1.48 aadminkey 12345
set port lacp port ge.1.48 disable

we are pinging the Ip address of the default vlan:

X450-g2-01 : 192.168.0.248/23

X450-g2-02: 192.168.0.249/23

I'm not on site of the customer, but I just did ask the customer to send me the config files

with part of the config do you need?
