RxPause on Catalyst 5500

Hi, I have a server connected to a Gigabit Ethernet Port on a catalyst 5509 with flowcontrol enable. We lost connectivity to the server and the number of RxPause in the "sh port" output of the Catalyst GE port increased a lot. We already solved the problem by decreasing the number of connections to the server, but´I´d like to know what exactly means the RxPause counter on the "sh port " output. Thanks ahead!

Re: RxPause on Catalyst 5500

RxPause is the Catalyst count of a Gigabit Ethernet Flow Control Pause frame. These are sent from hosts connected to it basically saying "back off" with regards to data transmission. Here is a link to discuss this more on your Catalyst.

Snip from the link

Flow control is a feature that Gigabit Ethernet ports use to inhibit the transmission of incoming packets. If a buffer on a Gigabit Ethernet port runs out of space, the port transmits a special packet that requests remote ports to delay sending packets for a period of time. This special packet is called a pause frame.

Hope this helps you,

Don
