I've only just started managing these switches so I don't know why flow-control
is off & mtu not set higher. I'm assuming mtu should be higher to allow some
overhead on the packet. I have noticed that there are quite a few gaint frames
in the network.
Also do I need to use the me0 interface for management of the switch for access
?
For a better view I've attached the configs of both switches.
Regards
Paul
