Set Auto-Negotiation Options
The negotiation auto command provides a mode option for conguring an individual port to forced master/ forced slave after
you enable auto-negotiation.
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 tengig 0/0
Dell(conf-if)#neg auto
Dell(conf-if-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-autoneg)#mode ?
forced-master Force port to master mode
forced-slave Force port to slave mode
Dell(conf-if-autoneg)#
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.
When you use the configured keyword, only interfaces that have non-default congurations display.
Example of show Commands that Use the configured Keyword
Example of the show interfaces switchport Command
The following example lists the possible show commands that have the congured keyword available:
Dell#show interfaces configured
Dell#show interfaces tengigabitEthernet 0 configured
Dell#show ip interface configured
Dell#show ip interface tengigabitEthernet 1 configured
Dell#show interfaces fortygigabitEthernet 0 configured
Dell#show ip interface fortygigabitEthernet 1 configured
Dell#show ip interface brief configured
Dell#show running-config interfaces configured
Dell#show running-config interface tengigabitEthernet 1 configured
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.
