Catalyst migration from 2950 to 2960S

[David Martinez Garcia]

We are migrating a network access switches in stack 2950 to 2960. There are hubs in the current network and they are working correctly but to migrate to the new network are errors and increases the number of collisions.

The configuration in the acces ports where the hubs are connected is always the same.

Thanks very much,

Hi David,

Did you configure the ports to the hubs on half duplex? It could be a mismatch in the auto-negotiation that causes errors and (late) collisions.

(of course it is always better to replace any hubs with the old 2950s...
