NOTE: The show interfaces status command displays link status, but not administrative status. For both link and
administrative status, use the show ip interface [interface | brief] [configuration] command.

In the previous example, several ports display “Auto” in the Speed eld, including port 0/1. In the following example, the speed of port 0/1 is
set to 100Mb and then its auto-negotiation is disabled.

Auto-Negotiation on Ethernet Interfaces
Setting Speed and Duplex Mode of Ethernet Interfaces
By default, auto-negotiation of speed and duplex mode is enabled on 1GbE and 10GbE Ethernet interfaces on an Aggregator.
The local interface and the directly connected remote interface must have the same setting. Auto-negotiation is the easiest way to
accomplish these settings, as long as the remote interface is capable of auto-negotiation.
NOTE
: As a best practice, Dell Networking recommends keeping auto-negotiation enabled. Auto-negotiation should only be
disabled on switch ports that attach to devices not capable of supporting negotiation or where connectivity issues arise from
interoperability issues.
For 100/1000/10000 Ethernet interfaces, the negotiation auto command is tied to the speed command. Auto-negotiation is always enabled
when the speed command is set to 1000 or auto. In Dell Networking OS, the speed 1000 command is an exact equivalent of speed auto
1000 in IOS.
To discover whether the remote and local interface require manual speed synchronization, and to manually synchronize them if necessary,
follow these steps.
