Hi all,
I have a little question for you.
I have a FR 2 Mbits on my serial 1 (1721 router)
When i do a show int serial 1 i get the following
CAPOROUTER#show int serial 1
Serial1 is up, line protocol is up
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec,
reliability 255/255, txload 58/255, rxload 57/255
Encapsulation FRAME-RELAY IETF, loopback not set
Keepalive set (10 sec)
LMI enq sent 249017, LMI stat recvd 249016, LMI upd recvd 0, DTE LMI up
LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
LMI DLCI 0 LMI type is CCITT frame relay DTE
FR SVC disabled, LAPF state down
Broadcast queue 0/64, broadcasts sent/dropped 40165/0, interface broadcasts 0
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters 4w0d
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 49182
Queueing strategy: weighted fair
Output queue: 0/1000/64/49182 (size/max total/threshold/drops)
Conversations 0/48/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
<b> Available Bandwidth 1536 kilobits/sec<b>
5 minute input rate 464000 bits/sec, 141 packets/sec
5 minute output rate 473000 bits/sec, 148 packets/sec
172430598 packets input, 474513113 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
9 input errors, 0 CRC, 1 frame, 0 overrun, 8 ignored, 0 abort
186554447 packets output, 379233418 bytes, 8 underruns
8 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
Can you please clarify the bold statements in the show command
I jknow bandwidth is set to 2000 cause i declare it.
Why do i have then the Available bandwidth to 1530 Kbps ?????
Can you pleae shed some light on this?
thanks,
George

It earmarks a nominal 25% for overheads and routing protocols. The "available" bandwidth is a typical figure. If you are not running any routing protocols, you will be able to get closer to the 2 Mbps through the pipe.

If you want to check the CIR configured on the telco switch debug the frame-relay lmi on your serial 1.
router# debug frame-realy lmi int serial 1
router# terminal monitor
look for a line like this one under
8w4d: PVC IE 0x7 , length 0x6 , dlci xxx, status 0x2 , bw 2048000
if the bw is 2048000 the cir on the switch FR is
configured right, otherwise call the telco.
Once you have finished to check the interface type
router# undebug all
router# terminal no monitor
enjoy your debug,
Marco.
