Setting Auto-Negotiation Options
The negotiation auto command provides a mode option for configuring an individual port to forced master/
forced slave after you enable auto-negotiation.
Table 22-5. Auto-Negotiation, Speed, and Duplex Settings on Different Optics
Figure 22-27 showstheauto‐negotiationoptions.
Caution: Ensure that only one end of the node is configured as forced-master and the other is configured as
forced-slave. If both are configured the same (that is, both as forced-master or both as forced-slave), the
show
interface
command flaps between an auto-neg-error and forced-master/slave states.
