Setup Guide

Set Auto-Negotiation Options
The negotiation auto command provides a mode option for conguring an individual port to forced master/ forced slave once auto-
negotiation is enabled.
CAUTION: Ensure that only one end of the node is congured as forced-master and the other is congured as forced-slave. If
both are congured the same (that is, both as forced-master or both as forced-slave), the show interface command aps
between an auto-neg-error and forced-master/slave states.
Example of the negotiation auto Command
For details about the speed, duplex, and negotiation auto commands, refer to the Interfaces chapter of the Dell EMC Networking
OS Command Reference Guide.
NOTE: While using 10GBASE-T, auto-negotiation is enabled on the external PHY by default, and auto-negotiation should be
enabled on the peer for the link to come up.
Adjusting the Keepalive Timer
To change the time interval between keepalive messages on the interfaces, use the keepalive command. The interface sends keepalive
messages to itself to test network connectivity on the interface.
To change the default time interval between keepalive messages, use the following command.
• Change the default interval between keepalive messages.
INTERFACE mode
keepalive [seconds]
• View the new setting.
INTERFACE mode
show config
View Advanced Interface Information
The following options have been implemented for the show [ip | running-config] interfaces commands for (only)
interfaces.
When you use the configured keyword, only interfaces that have non-default congurations are displayed. Dummy interfaces (created
with the
stack-unit command) are treated like any other physical interface.
Examples of the show Commands
The following example lists the possible show commands that have the congured keyword available:
In EXEC mode, the show interfaces switchport command displays only interfaces in Layer 2 mode and their relevant
conguration information. The
show interfaces switchport command displays the interface, whether it supports IEEE 802.1Q
tagging or not, and the VLANs to which the interface belongs.
Conguring the Interface Sampling Size
Although you can enter any value between 30 and 299 seconds (the default), software polling is done once every 15 seconds. So, for
example, if you enter “19”, you actually get a sample of the past 15 seconds.
All LAG members inherit the rate interval conguration from the LAG.
The following example shows how to congure rate interval when changing the default value.
To congure the number of seconds of trac statistics to display in the show interfaces output, use the following command.
