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.
