I am trying to implement LLQ across several switches. Our Cisco IP phones are attached to 3560 POE switches that are configured only at layer 2. They trunk to a 6509. I want to set up egress queues on that trunk so that voice traffic has priority and takes up a specified amount of the bandwidth. I tried to implement the following commands but when I get to the policy-map there are no commands available for "priority" or "bandwidth".
I'm new at this. For weeks I've been trying to learn QoS and VOIP by reading from various Cisco books (QOS 642-642 book, CCNP ONT 642-845 book, etc.) and online documents. I would be grateful for any help that anyone can give.
!Configure the class-maps for VOIP and VOIP signaling.
match ip dscp ef
match ip dscp af31
!Configure the policy-map to reserve the bandwidth on 2GB PO egress queues
priority percent 37 (740,000 Kbps)
bandwidth percent 13 (260,000 Kbps)
!Set the bandwidth on the 2GB PO interface and apply the policy-map outbound.
service-policy output llq-voip-2gb
Thank you very much!
I've found that echo is normally caused by the telco connection. Looking at the errors on your prime, I'd say get the fixed first, and see where you are at after that.
