packet loss problem

I have 4 network ports on our T5240 sun server.

all but 1 gives packet losses (nxge1)

nxge0 gives on average 50% packet loss, very bad.

nxge2 gives on average 1-2% packet loss.

nxge3 gives on average 20% packet loss.

Is there a tool or something to help me find the problem?

NAME
aecho - send AppleTalk Echo Protocol packets to network hosts SYNOPSIS
aecho [ -c count ] ( address | nbpname ) DESCRIPTION
aecho repeatedly sends an Apple Echo Protocol (AEP) packet to the host specified by the given AppleTalk address or nbpname and reports whether a reply was received. Requests are sent at the rate of one per second. address is parsed by atalk_aton(3). nbpname is parsed by nbp_name(3). The nbp type defaults to `Workstation'. When aecho is terminated, it reports the number of packets sent, the number of responses received, and the percentage of packets lost. If any responses were received, the minimum, average, and maximum round trip times are reported. EXAMPLE
Check to see if a particular host is up and responding to AEP packets: example% aecho bloodsport 11 bytes from 8195.13: aep_seq=0. time=10. ms 11 bytes from 8195.13: aep_seq=1. time=10. ms 11 bytes from 8195.13: aep_seq=2. time=10. ms 11 bytes from 8195.13: aep_seq=3. time=10. ms 11 bytes from 8195.13: aep_seq=4. time=10. ms 11 bytes from 8195.13: aep_seq=5. time=9. ms ^C ----8195.13 AEP Statistics---- 6 packets sent, 6 packets received, 0% packet loss round-trip (ms) min/avg/max = 9/9/10 OPTIONS
