Changing the default Gigabit negotiation mode

You can configure the default Gigabit negotiation mode to be one of the following:
•
•
•
Unless the ports at both ends of a Gigabit Ethernet link use the same mode (either auto-gig or
neg-off), the ports cannot establish a link. An administrator must intervene to manually configure
one or both sides of the link to enable the ports to establish the link.

Changing the negotiation mode

To change the mode for individual ports, enter commands such as the following.
BigIron RX(config)# int ethernet 4/1 to 4/4
BigIron RX(config-mif-4/1-4/4)# gig-default neg-off
This command changes the default auto-gig setting and sets the negotiation mode to neg-off for
ports 4/1 – 4/4.
Syntax: gig-default neg-full-auto | auto-gig | neg-off
Default is gig-default auto-gig
The neg-full-auto, auto-gig, and neg-off options are as described above.

Disabling or re-enabling flow control

You can configure full-duplex ports on a system to operate with or without flow control (802.3x).
Flow control is enabled by default.
To disable flow control on full-duplex ports on a system, enter the following.
BigIron RX(config)# no flow-control
