● Half duplex cannot be configured when the flow control configuration is on (default is rx on tx
on). The following error is returned:
Can’t configure half duplex when flowcontrol is on, config ignored
NOTE: The flow control must be off (rx off tx off) before configuring the half duplex.
● Speeds less than 1 Gig cannot be configured when the asymmetric flow control configuration is on.
The following error is returned:
Can’t configure speed <1G when Asymmetric flowcontrol is on, config
ignored
● Dell Networking OS only supports rx on tx on and rx off tx off for speeds less than 1 Gig
(Symmetric).
NOTE: If you use the disable rx flow control command, Dell Networking recommends
rebooting the system.
