Set Auto-Negotiation Options
The negotiation auto command provides a mode option for configuring an individual port to forced master/ forced slave
once auto-negotiation is enabled.
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.
Example of the negotiation auto Command
DellEMC(conf)# int tengigabitethernet 1/1/1
DellEMC(conf-if-te-1/1/1)#neg auto
DellEMC(conf-if-te-1/1/1-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
DellEMC(conf-if-te-1/1/1-autoneg)#mode ?
forced-master Force port to master mode
forced-slave Force port to slave mode
DellEMC(conf-if-te-1/1/1-autoneg)#
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)
stack-unit interfaces.
When you use the configured keyword, only interfaces that have non-default configurations are displayed. Dummy stack-unit
interfaces (created with the stack-unit command) are treated like any other physical interface.
The following example lists the possible show commands that have the configured keyword available:
DellEMC#show interfaces configured
DellEMC#show interfaces stack-unit 1 configured
DellEMC#show interfaces tengigabitEthernet 1 configured
DellEMC#show ip interface configured
