The Tx data rate at one end of a serial connection doesn't match the Rx rate at the other end (both BW 3072 Kbit), with Sprint in the middle; Sprint says there is no problem:


Hssi2/0.6 is up, line protocol is up
Hardware is M1T-HSSI-B
Description: PVC to Augusta, GA (ga-augusta-river) - DLCI 54
Internet address is 10.0.0.5/30
MTU 1500 bytes, BW 3072 Kbit, DLY 200 usec,
reliability 255/255, txload 140/255, rxload 42/255 <<----------- Tx load of 55%
Encapsulation FRAME-RELAY




Serial0/0.1 is up, line protocol is up
Hardware is DSCC4 Serial
Description: PVC to Atlanta, GA (ga-atlanta-cumberla) - DLCI 31
Internet address is 10.0.0.6/30
MTU 1500 bytes, BW 3072 Kbit, DLY 20000 usec,
reliability 255/255, txload 14/255, rxload 51/255 <<-------- 20% Rx load
Encapsulation FRAME-RELAY


Does this make sense to anyone?
 
There is definately no problem here. While in theory they should be the same there may be a difference on both ends of the circuit. Maybe its the cable type, cable age, weather... Also for future reference you may want to x-out your IP address and DLCI's and description.

Also as a side note: I believe that in a PVC or SVC Frame-relay network you can be switched up to fifteen times before reaching your destination. Your path in either direction can take a different path. Hope this helps.
 
What's Sprint's CIR? Also, since both are subinterfaces, what's the bandwidth of the major interface on each end?
