MLAG Configuration

MLAG Configuration

Hello;

I have configured an MLAG between 2 X590 routers with a double LACP link between them. This is my configuration:

create vlan "MLAG_CORE"
configure vlan MLAG_CORE tag 250
enable sharing 29 grouping 29,33 algorithm address-based L2 lacp
configure vlan MLAG_CORE add ports 29 tagged
configure vlan MLAG_CORE ipaddress 10.250.0.2 255.255.255.252
create mlag peer "CORE"
configure mlag peer "CORE" ipaddress 10.250.0.1 vr VR-Default
configure mlag peer "CORE" lacp-mac 00:04:96:e5:17:94

This is the output of the command:

 R-A52.2 # sh mlag peer
Multi-switch Link Aggregation Peers:

MLAG Peer         : CORE
VLAN              : MLAG_CORE              Virtual Router    : VR-Default

But when I run the following command it doesn't give me any information:

 

 R-A52.3 # sh mlag ports

                          Local                                                        Local     Remote

                  Down - No links are active on the remote switch,
                  N/A - The peer has not communicated link state for this MLAG port,
                  Virtual - MLAG peer switch does not have physical port.

Number of Multi-switch Link Aggregation Groups  : 0
Convergence control                             : Conserve Access Lists
Reload Delay Interval                           : 30 seconds
Reload Delay                                    : Disabled
Link Up Isolation                               : Off
 

I am missing any configuration ??, or is it that I have not created downlink  yet.

you forgot to enable sharing on port 22 on both mlag peers

Hello,

up do now you have only bound the two switches together and enable mlag.

Now you have to use the mlag for other switches or server.

For example with (on both switches): enable sharing 17 grouping 17 algorithm address-based L3_L4 lacp

 

With that line on both switches from the server perspective your two switches working as a one switch and now you will see an entry with show mlag ports.
