We have several Catalyst 2950 switches over multiple sites that are connected via a BT LES (fibre) 10Mb deditacted lines.
When looking at the port statistics for these lines they are showing multiple Transmit errors (at both ends of the connection), more specifically Total collisions and Late collisions.
I am trying to find out why this is and what we can do about it, as I'm sure it should not be happening.
These ports are all set to 10Mb half duplex.
Any advice gratefully received!
