Auto-Negotiation On Ethernet Interfaces; Setting Speed And Duplex Mode Of Ethernet Interfaces - Dell PowerEdge M IO Aggregator Command Reference Manual

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 Force10 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
Auto-negotiation is always enabled when the
command is an exact equivalent of
1000
To discover whether the remote and local interface require manual speed synchronization, and to manually
synchronize them if necessary, follow these steps (also refer to
Step Task
1 Determine the local interface status. Refer
to Figure
2 Determine the remote interface status.
3 Access CONFIGURATION mode.
4 Access the port.
5 Set the local port speed.
6 Optionally, set full- or half-duplex.
7 Disable auto-negotiation on the port. If the
speed is set to 1000, you do not need to
disable auto-negotiation
8 Verify configuration changes.
