Hi Team,

           Kindly suggest regarding following practical case If I connect a p.c/laptop with 10/100 lan card capacity to a 1 gbps port switch port congestion/packet drop might happen???

My switch is X440G2-48p-10G4

Thanks in advance

Roy,

I think you should test the different settings because the behavior can be different depending on the specific environment and devices.

There is no negative effect on the switch. The only impact is to drop more or less packets on the device interface.

Flow Control:    Rx-Pause: Enabled    Tx-Pause: Disabled

Above is my each port status, kindly suggest what should I do to minimise packet drops, should I disable both against all ports or enable to minimise packet drops, or just disabled/enable this against one port for testing purpose, is their any negative affect on switch for disabling flow control?

Thnx

Roy,

In this case check the status before to see if it is activated or not.

Commands disable it are mentioned in the following post:

show / enable / disable have to be used with the arguments.

Roy,

This analysis domain is quite tricky because the impacted devices are not necessarily the triggers of the packet drops.

For this you need specific devices to analyze the network traffic.

• Extreme Application Analytics can be a good starting point.
• Fluke Optiview is an example of dedicated device but it has his cost…
