Hi Bonnie,


In the case of 2900XL switches you can see the flowcontrol status can be seen on the show int mod/port output.


Example:

Switch#show int fa 0/18

FastEthernet0/18 is down, line protocol is down

Hardware is Fast Ethernet, address is 0009.b75b.bd12 (bia 0009.b75b.bd12)

Description: Dave Shafer - Office Machine LINUX

MTU 1500 bytes, BW 100000 Kbit, DLY 1000 usec,

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

Full-duplex, 100Mb/s

input flow-control is off, output flow-control is off <<<<< Please see this line


To change the Flowcontrol you can use the following commands: (Only Supported on the Gigabit ports)


switch(config-if)#flowcontrol {asymmetric | symmetric}


asymmetric:Enable the local port to perform flow control of the remote port. If the local port is congested, it can request the remote port to stop transmitting. The local port requests that the remote port begin transmitting after the congestion clears.


symmetric: Enable the local port to perform flow control only if the remote port can also perform flow control of the local port. If the remote port cannot perform flow control, the local port also does not.
