Post by shailu2014 »

Hi,

I have four 2960 switch (cisco WS-C2960S-48TD-L) all switch interface port is GigabitEthernet and switch connected within stack.

When configuration time of Cisco 2960 switch for monitoring some port showing 10.00 Mbps and some port showing 1.00 Gbps in Max speed and same things happen in Bandwidth Rate also (Rate In 500 Rate Out: 500) (Rate In 5 Rate Out: 8), all port should show same speed 1.00 Gbps and same bandwidth rate (Rate In 500 Rate Out: 500). Please help me, Why it is showing like that .....

Sjain

I believe this is polling the current negotiated speed, not necessarily the actual port speed, but I would have to check that to be 100%. Is it possible that some of these ports are connected to slower devices and thus this is accurate for active port speed not listed port speed?

But what speed was negotiated? If the link is slow, port negotiation may use a slower speed (like 100mb/s) if there were issues with 1gb/s.
What does the windows devices report for their interface properties? Is there another device between the cisco switch and the workstations?
