Pause input frames

Hello all, I'm a bit of a novice at this and I could do with a bit of advice on some interface output. We have had problems with data transfer involving the server on this Gb port. The only anomalous output I can see is the high incidence of pause input frames. Can anyone shed any light on what these are? Do they signify a problem?

Output is below (I have tried running through the Output Interpreter, but it didn't tell me anything useful)

gigswc2#sh int g0/8

GigabitEthernet0/8 is up, line protocol is up

Hardware is Gigabit Ethernet, address is 000b.4601.9e08 (bia 000b.4601.9e08)

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

Full-duplex mode, link type is force-up, media type is SX

output flow-control is unsupported, input flow-control is unsupported, 1000Mb/

input flow-control is off, output flow-control is on

Take a look at the link below. It explains what paused input packets are. It has to do with flow control which is turned on for output packets. You should turn flow off since it is not supported on this interface.
