I'm trying to configure 2 x 3750G-12S switches as core or callapsed core/distribution switches. I have never done this before and would like someones advise on the best configuration please?
My thoughts are having 6 Vlans 1,10,20,30,40,50 each connecting to a switch block consisting of 3560G,3500 and 2960G switches (access layer). These are linked together in a daisy chain fashion and connect back to both 3750G (Core/Distribution) switches via fibre on the top and bottom switches in the block/stack (Obviously there will be 5 or 6 switch blocks).
By putting all sw blocks in a seperate Vlans, how do I control stp? - I was advised to have half the vlans using "core_sw_1" as a root for stp and the other half using "core_sw_2", thus sharing the load, but have not worked out how to achieve this!
I no that the cores are running in PVST mode by default. I have tried to configure vlan 1,10,20 to use core 1 as the root for stp but the "set spantree" or "set spanning-tree" command is not recognised, what commands do i use? or what should I do to set the core switch as root on the grouped vlans?
Please give me as much advise as possible!!
