Distributed Trunking – Core and Access Switches Setup

You can do virtually anything Cisco does on ProCurves. It's just a tiny little bit of a different logic when implementing the configuration. You can setup VRRP (and of course different STP root bridges) on distribution layer switches, which will perform inter-vlan routing, to load balance the traffic from different VLANs between the switches.

For example, you can set one switch as a VRRP master for 1,3,5 floor VLANs and the second one for 2,4 floor VLANs or similar.

First, it is invalid to configure more than one untagged VLAN per port. Into which VLAN does an untagged packet belong? Thus, VLAN 1 (management) should exist, and be the PVID, only on trunk ports. (PVID 10 everywhere else.)

Second, unless a switch is acting as a router (eg. the core switch), it doesn't need an ip on any non-management interfaces. Thus, the default gateway for devices in VLANs 10 and 20 (and 1) should be the relevant address of the core switch.

With this setup, the VoIP devices need to know to use VLAN 20. This can be via direct configuration, maybe DHCP(???), or CDP/LLDP^[1].
