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
Dell(conf)# int gigabitethernet 1/1
Dell(conf-if-gi-1/1)#neg auto
Dell(conf-if-gi-1/1-autoneg)# ?
end Exit from configuration mode
exit Exit from autoneg configuration mode
mode Specify autoneg mode
no Negate a command or set its defaults
show Show autoneg configuration information
Dell(conf-if-gi-1/1-autoneg)#mode ?
forced-master Force port to master mode
forced-slave Force port to slave mode
Dell(conf-if-gi-1/1-autoneg)#
For details about the speed, , and negotiation auto commands, refer to the Interfaces chapter of the Dell 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) stack-unit
interfaces.
When you use the configured keyword, only interfaces that have non-default congurations are displayed. Dummy stack-unit 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:
Dell#show interfaces configured
Dell#show interfaces stack-unit 1 configured
Dell#show interfaces tengigabitEthernet 1 configured
