Re: VoIP QOS on a 4506 switch with Avaya PBX - need help.
There can be an issue because of the shape and bandwidth command (33%). The shape command is used to set an upper limit for the respective queue. From the link in the previous post:
"Strict Priority / Low Latency Queueing
You can configure transmit queue 3 on each port with higher priority using the priority high tx-queue configuration command in the interface configuration mode. When transmit queue 3 is configured with higher priority, packets in transmit queue 3 are scheduled ahead of packets in other queues.
When transmit queue 3 is configured at a higher priority, the packets are scheduled for transmission before the other transmit queues only if it has not met the allocated bandwidth sharing configuration. Any traffic that exceeds the configured shape rate will be queued and transmitted at the configured rate. If the burst of traffic, exceeds the size of the queue, packets will be dropped to maintain transmission at the configured shape rate."
So if you connect your PBX directly to the port at 100 Mbps speed, I would remove the shape command. On a PBX port I would not pose any limit to voice traffic.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
