I have 34.368Mbps internet link. On the remote site there is a Juniper router. And as encapsulation type it uses Cisco HDLC. In the recive site i have a satellite modem. I recieve the signal. I configured my HSSI interface with HDLC encapsulation. On the HSSI interface of my router i see only 500Kbps of data rate in fact it should be about 30 Mbps. (I use show interface HSSI command, HSSI 1/0 is up, line protocol is up ).
At least i have to see the correct input on my interface but i cant.
Do you have any idea about this problem.
Do you think that is that because i did something worng on my cisco configuration.

could you post any interface info? sh int? sh run int hssi1/0?

Not really clear what the sattellite modem is or how that falls into play here?

interface Hssi1/0
 ip address 192.168.2.112 255.255.255.0
 no ip mroute-cache
 load-interval 30
 no keepalive
 no cdp enable
 hold-queue 4096 in
 hold-queue 4096 out
end
Sorry to tell that i dont have a chance to write the output of "show interface hssi" command. But the main thing is that "30 second output rate 510 bits/sec" and there are a lot of crc errors. But the link is E3 so i should see that date rate on the interface but i cant.

I mean this is a link via satellite. It is a one way link. The remote site transmits and i am trying to recieve. I have a similar link that uses Frame-Relay as encapsulation. On that configuration there is no problem. But this link uses HDLC and even i cant see the correct input data value on the interface.

hmmm...i didn't think I had answered the question yet ;)

A lot of CRC errors? You could just have a bad feed from your provider. Clear the counters fresh and verify if the counters are incrementing. if so, how quickly? if it's negligible or nothing, do an extended ping from hssi interface to juniper interface. Start with 500 or so pings or so to see if anything jumps at you.

Also, if it's not the 'circuit' that causing problems, does the FR circuit and the sattellite connect to the same provider? What routing protocols are you using(if any).

I also wouldn't be surprised if the satellite just has a boatload of latency on top of it, which can't be helping, but you should still be able to get a bit more throughput than 500K/s

I'd call your carrier about your circuit after making sure that all your wiring is clean.

This kind of noise on a link is killing you:

  Last clearing of "show interface" counters 00:10:06
    5719140 input errors, 4587362 CRC, 0 frame, 14 overrun, 0 ignored, 1131764 abort

That's a boatload of errors for 10 minutes.
