Hey Guys,
Im looking at the QOS rolled out accross the network where I am working in particular the queuing stratagys, I am however getting conflicting information and im not sure if one has priority over another.
For instance -
Router#sh int gi10/3
GigabitEthernet10/3 is up, line protocol is up (connected)
Hardware is C6k 1000Mb 802.3, address is
Description: D052
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s, media type is 10/100/1000BaseT
input flow-control is off, output flow-control is off
Clock mode is auto
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:33, output hang never
Last clearing of "show interface" counters never
Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 1000 bits/sec, 3 packets/sec
150413 packets input, 9836822 bytes, 0 no buffer
Received 169 broadcasts (126 multicasts)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 3 frame, 0 overrun, 0 ignored
0 watchdog, 0 multicast, 0 pause input
0 input packets with dribble condition detected
284178 packets output, 359390954 bytes, 0 underruns
0 output errors, 0 collisions, 2 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier, 0 PAUSE output

Router#
#sh queueing int gi10/3
Interface GigabitEthernet10/3 queueing strategy: Weighted Round-Robin
Port QoS is enabled
Trust boundary disabled
Trust state: trust DSCP
Extend trust state: not trusted [COS = 0]
Default COS is 0
Queueing Mode In Tx direction: mode-cos
Transmit queues [type = 1p3q8t]:
Queue Id Scheduling Num of thresholds
-----------------------------------------
01 WRR 08
02 WRR 08
03 WRR 08
04 Priority 01
My question is why does the show int stats show the queueing strategy as FIFO but when you issue the sh queuing int xxx command it says the strategy is WRR, which one sould I take notice of?
Would appreciate if any one has an answer.
Thanks,
Ricky
