Dear Team,

Please guide how to configure below type of configuration.

How to set vlan under the interface after stack configuration and what will be configuration on CBS-48T switches. 

Please guide.

You will likely need:

• One port channel on each access-switch with member interfaces to both core-switches.
• On the core you have four port channel to each access-switch with member interfaces from both cores.
• All port channels are configured as trunk
• Hopefully the access-switches are nearby as you don't have enough SFP ports on the core to connect them with fibre.

Sir, yes i will do  the Port channel on copper interface caused its no of 8 access switches. do you any reference link and documents for the configuration, also core switches is in HA mode ..

[Karsten Iwen]

The core switches need to be a stack (HA) to be able to span a port-channel over both member switches. You should be able to find all you need in the administration guide:

• Building the channels (LAG)
• The core switches should be configured as STP root
• Setting Interfaces to trunk or access

If you run into problems, just come back with your questions.
