IP RTP Prioritization Example

IP RTP Prioritization Example

• interface Serial0/0
• bandwidth 128
• ip address 10.0.0.1 255.255.255.252
• encapsulation ppp
• fair-queue
• ip rtp priority 16384 16383 50
• !

• Router#show queue serial0/0
• Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
• Queueing strategy: weighted fair
• Output queue: 0/1000/64/0 (size/max total/threshold/drops)
• Conversations 0/1/256 (active/max active/max total)
• Reserved Conversations 0/0 (allocated/max allocated)
• Available Bandwidth 46 kilobits/sec
• Router#

• Up to 75% of configured bandwidth is reservable.
• BWavail = BW * 0.75 - BWRTP
