Voice VLAN on SG300 Switches

[Andi Bigelow]

I have a pair of SG300-52 switches, each connected via LAG (Po1 on each switch) to the firewall uplink. These LAGs are configured as dot1q trunks carrying native (1), management, and three data VLANs to the firewall. Both work great. The switches are also cross-connected to one another on another LAG (Po2) that carries only the VLAN designated as the auto voice VLAN, in this case 200, and the native (1). Traffic traverses the trunks just fine on the data VLANs, but for some reason the auto voice VLAN data does not go switch to switch via Po2. Po2 shows active and all links in it are active, but it's not passing data. Is there something about the auto voice VLAN that prevents it jumping switch to switch?

Have you got anything telling it that the voice vlan is 200 (for it to automatically learn this)?  Otherwise just statically configure it as VLAN 200.

I did define it as the voice vlan. Are you suggesting that I should disable the auto voice vlan and simply make it another VLAN? Won't hurt me from a QoS perspective, I don't think, since I'm not sharing links to the voice gateway with other VLAN's.

[Philip D'Ath]

Yes, that is what I am suggesting.
