Hub and T1

That's what I though. How would I do it with a CSU/DSU? From what I am looking at there isn't a way to do it with the csu/dsu.

what type of circuit is plugged into the CSU?  and do you see errors CRC Frame ect?

Thanks
scott

T1 circuit. No errors.

what type of T1 point to point or frame?  and what is on the other end?

Thanks
Scott

it's going into a PRN cloud. Encapsulation is HDLC.

so when you do a show int s0/0 or whatever what do you see or get?

Thanks
Scott

Hardware is GT96K with integrated T1 CSU/DSU
Internet address is xxxx
MTU 1500 bytes, BW 1500 Kbit, DLY 20000 usec,
   reliability 255/255, txload 50/255, rxload 5/255
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 1w5d
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 8
Queueing strategy: priority-list 1
Output queue (queue priority: size/max/drops):
   high: 0/20/0, medium: 0/40/0, normal: 0/60/8, low: 0/80/0
5 minute input rate 35000 bits/sec, 22 packets/sec
5 minute output rate 295000 bits/sec, 31 packets/sec
   6337012 packets input, 3326616677 bytes, 0 no buffer
   Received 295853 broadcasts, 0 runts, 0 giants, 0 throttles
   0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
   6515449 packets output, 3648942045 bytes, 0 underruns
   0 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

maybe I am missing something here so lets take a step back you are recieving packets on the serial .... what are you trying to do or determine?

5 minute input rate 35000 bits/sec, 22 packets/sec
5 minute output rate 295000 bits/sec, 31 packets/sec

are you trying to determine type of traffic???

Thanks
scott

no . We have an application that uses FTP to transfer data. at two of our locations the FTP traffic stops as soon as it starts sending 167 byte packets. According to a packet sniffer, the server site is sending the packets and when sniffing at the client location, that location is never receiving them. So i wanted to check to see if the packets are even getting out of the router and onto the T1.

clear counters and start your ftp when it supposedly stops sending look at the counters are they still incementing if so your data is still hitting the T1.

Thanks

The provider cannot see the info either since it's a PRN network.

Then if you want to add some hardware and software, look at these --
