Hello,

We have 2 X 24 port DS 300B switches and looking to upgrade the port with 48 ports.

Can we make the old 2 X 24 port switch as one switch with 48 ports and ISL ?

I believe we need to have ISL for trunking.

Should we need trunking license for ISL if i don't need any link aggregation  and all?

Thanks in Advance ,
