What means "Available Bandwidth ...." in a show interface s0/0 cmd ?

We configured a bandwidth 2048 and in the below show cmd we see an available bandwidth of 1536 k/sec.

What does it mean ?

Serial0/0 is up, line protocol is up

Hardware is PowerQUICC Serial

Internet address is 62.134.9.34/30

MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec,

reliability 255/255, txload 36/255, rxload 28/255

Encapsulation HDLC, loopback not set

Keepalive set (10 sec)

Last input 00:00:00, output 00:00:00, output hang never

Last clearing of "show interface" counters 00:25:00

Input queue: 1/75/0/0 (size/max/drops/flushes); Total output drops: 2148

Queueing strategy: weighted fair

Output queue: 0/1000/64/2148 (size/max total/threshold/drops)

Conversations 0/37/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

Available Bandwidth 1536 kilobits/sec

5 minute input rate 225000 bits/sec, 31 packets/sec

5 minute output rate 291000 bits/sec, 46 packets/sec

61464 packets input, 37440496 bytes, 0 no buffer

Received 150 broadcasts, 0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

86019 packets output, 61969076 bytes, 0 underruns

0 output errors, 0 collisions, 0 interface resets

0 output buffer failures, 0 output buffers swapped out

0 carrier transitions

Re: What means "Available Bandwidth ...." in a show interface s0

The inferface "bandwidth" command is primarily used to alter routing decisions rather than effecting the data rate of an interface. So, your BW setting of 2048 has nothing to do with the actual data rate (or clockrate) of an interface. On serial ptp interfaces, if you are trying to change a datarate you can use the clockrate command on the DCE side to accomplish this.

Hope this helps,

Don
