sh int se0/0

Hi Guys ,

I want to the details of output shown below ,

Router#sh int se0/0

Serial0/0 is up, line protocol is up

Hardware is PowerQUICC Serial

Description: Connected to Leeds on 2Mb

Internet address is 177.198.91.203/30

MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec,

reliability 255/255, txload 4/255, rxload 24/255

Encapsulation HDLC, loopback not set

Keepalive set (10 sec)

Last input 00:00:04, output 00:00:00, output hang never

Last clearing of "show interface" counters 37w3d

Input queue: 4/75/453/0 (size/max/drops/flushes); Total output drops: 7190

Queueing strategy: weighted fair

Output queue: 0/1000/64/7112 (size/max total/threshold/drops)

Conversations 0/235/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

Available Bandwidth 1488 kilobits/sec

5 minute input rate 189000 bits/sec, 26 packets/sec

5 minute output rate 37000 bits/sec, 21 packets/sec

486926690 packets input, 682966098 bytes, 0 no buffer

Received 2260668 broadcasts, 169 runts, 1957 giants, 0 throttles

6011579 input errors, 470371 CRC, 2773444 frame, 0 overrun, 0 ignored, 276

0 output errors, 0 collisions, 1878 interface resets

0 output buffer failures, 0 output buffers swapped out

864 carrier transitions

DCD=up DSR=up DTR=up RTS=up CTS=up

I want to understand what is DCD=up DSR=up DTR=up RTS=up CTS=up

then what is DCE...........

& why input errors are there & what is the solution for input errors

Re: sh int se0/0

DCD = Data Carrier Detect - Set by DCE to imply working link

DSR = Data Set Ready - Set by DCE to imply that the DCE is ready to signal using pins leads

DTR = Data Terminal Ready - Set by the DTE to imply that the DTE is ready to signal using pins leads

RTS = Request To Send - Set by the DTE to tell the DCE that the DTE wants to send data

CTS = Clear To Send - Set by the DCE to tell DTE that the DTE is allowed to send data.
