cant turn on flowcontrol as need to disable admin state

[robertkwild]

hi all,

i know the command to turn on flow control for an interface port

(config interface ethernet 1/19/3) # flowcontrol receive on

but getting this error

Interface is admin state enabled, please disable it first, and wait 3 seconds prior to Flow Control configuration.

but surely admin state needs to be enabled?

thanks,

rob

ok solved, i had to "shut" to disable the port then i could change the flowcontrol send/recieve on and then i did "no shut" on the port

BTW, I can see why the error message is confusing.  It's saying the current admin state for the interface is enabled. To change flow control, the admin state for the interface must be set to disabled and then wait 3 seconds before making the configuration change.  (I believe flow control is an option determined when link first comes up.  I.e. if you change it with interface "up", other side of link won't process the change.)

Also BTW, flow control, especially the all or nothing original variant, is often inadvisable to use.
