LLQ:Priority Queueing + debug

Creating Priority list

R1(config)#priority-list 1 protocol ip high tcp 23
R1(config)#priority-list 1 protocol ip medium tcp 3389
R1(config)#priority-list 1 protocol ip medium tcp 80
R1(config)#priority-list 1 protocol ip low tcp 20
R1(config)#priority-list 1 protocol ip low tcp 20
R1(config)#priority-list 1 default normal

assign to interface
R1(config)#int s0/0
R1(config-if)#prior
R1(config-if)#priority-group 1

Verify
R1(config-if)#do sh int s0/0
Serial0/0 is up, line protocol is up
Hardware is PowerQUICC Serial
Internet address is 11.0.0.1/8
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation FRAME-RELAY, loopback not set
Keepalive set (10 sec)
LMI enq sent 169, LMI stat recvd 170, LMI upd recvd 0, DTE LMI up
LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
LMI DLCI 1023 LMI type is CISCO frame relay DTE
Broadcast queue 0/64, broadcasts sent/dropped 311/0, interface broadcasts 63
Last input 00:00:04, output 00:00:04, output hang never
Last clearing of “show interface” counters 00:28:16
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: priority-list 1

R1#sh queueing priority

Current priority queue configuration:

debugging priority
R1(config-if)# do debug prior
R1(config-if)#do ping 4.4.4.4

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.4.4.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/60/61 ms
