[cisco-voip] Voice VLANs and Multiple Switches ?

[Ben Story]

You are correct in your notion that Cisco recommends a best practice to not
span VLANs between multiple switches (unless those switches are acting a
stackwise stack like the 3750 or 3750-E).  I believe you can find this
recommendation in the Campus Network for High Availability SRND at
http://www.cisco.com/en/US/docs/solutions/Enterprise/Campus/HA_campus_DG/hacampusdg.htmlamid
the Spanning Tree recommendations.
