Just to verify my current thinking. If I have two catalyst 6500s with supervisor engine (PFC2/MSFC2) with a Gigabit Etherchannel between them, and all access switches connecting to both switches, or cascaded (where the first and last connect to the core switches).
Several vlans, spread out on all access switches. In this design, what is the recommended setup?
My current thinking is Gibit Etherchannel in trunk mode, configure one of the 6500s as root for one half of the vlans, and the other 6500 as root for the other half of the vlans, have the MSFC configured for HSRP, where they are active for the same vlans as the 6500 is root for.
Is this still the recommended design, or are there better options today?
Thanks in advance,
That's pretty much what I would do - as Jon suggests one switch for odd, one for even and that is SPT root and HSRP active. For added elegance, tweak your routing protocol such that the active root/HSRP switch is the preferred route for incoming traffic!
If you can, manually prune the VLANS where they are not needed - it tidies the potential network for that VLAN and reduces the issues if you have spanning tree problems.
Also avoid using VLAN1 if you caan, just use it for control protocols, and block it from trunks.
Use UDLD if you have fibre links.
if available use RSTP. Configure all user ports as portfast, and use BPDU guard.
If you can use port security.
