Asanté IntraCore 36000 Series 

Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. 
Otherwise, back pressure jamming signals may degrade overall performance for the segment attached to 
the hub. 

Example 

The following example enables flow control on port 5. 

Console(config)#

interface ethernet 1/5

 

Console(config-if)#

flowcontrol

 

Console(config-if)#

no negotiation
