Create port sharing on 1 VSP switch using 2 ports

ExtremeNewbie — Mon, 25 Nov 2024 14:11:50 GMT

Hello Community,

I have a pair of 8404 VSP switches and wish to create a LAG (port channel) using 2 ports on the same switch and NOT across 2 switches. The ports are live and active and are plugged into the end device.

What is the best way to do this and does anyone have any examples of commands to use.

Both ports currently have the correct VLAN assigned, it's a case of joining the ports for redundancy.

Thanks All.

@jody998 - Many thanks for this. I will get the commands together and go through this and update this thread. I will be using SSH to the switches. The ports will be static so I am assuming a static LAG will suffice for this.

Lastly, there are some csharp and sql references. I am of the opinion these commands will run in SSH and there is no need to use csharp or sql?

Thanks,

Hey Asifi,

you can create a classic MLT. The configuration looks like this:

enable
conf t
#create mlt 1
mlt 1
# give mlt 1 a name
mlt 1 name ""
# add members to the mlt
mlt 1 member 1/1,1/2
# add vlan to the mlt member
vlan members add 100 1/1,1/2
# if you want to add more vlans to the mlt members, than you need to tag the mlt with the following command
mlt 1 encapsulation dot1q

be aware that both members need the same vlans configured with correct tagging to work properly.

best regards,

Philipp

@Phil_ Great - thanks for this, this has worked fine for me. A slight curveball on this, if I now want to use 2 core switch ports on 2 DIFFERENT switches what would be the process for this. I am thinking create an SMLT as split and patch the ports in?

Thanks,

Correct. SMLT is designed for this.

Same steps as before. You just need to add the following configuration:

interface mlt 1
smlt
exit

Best regards,
