16.5. Troubleshooting
Problem One
One of my links seems to be fine at low traffic levels, but starts to fail as traffic rates increase.
One of my links pings OK but has problems with FTP/SQL/HTTP/…
A possible cause of intermittent operation is that of a ‘duplex mismatch’. If one end of the link is fixed to
full-duplex and the peer auto-negotiates, the auto-negotiating end falls back to half-duplex operation.
At lower traffic volumes, the link may display few if any errors. As the traffic volume rises, the fixed
negotiation side will begin to experience dropped packets while the auto-negotiating side will experience
collisions. Ultimately, as traffic loads approach 100%, the link will become entirely unusable.
The ping command with flood options is a useful tool for testing commissioned links. The
command “ping 192.168.0.1 500 2” can be used to issue 500 pings each separated by two
milliseconds to the next switch. If the link used is of high quality, then no pings should be
lost and the average round trip time should be small.
Problem Two
I am trying to use the LFI protection feature but my links won’t even come up.
