In the previous example, several ports display “Auto” in the Speed eld, including port 0/1. In the following example, the speed of port 0/1 is
set to 100Mb and then its auto-negotiation is disabled.
Dell#configure
Dell(config)#interface tengig 0/1
Dell(conf-if-te-0/1)#speed 100
Dell(conf-if-te-0/1)#no negotiation auto
Dell(conf-if-te-0/1)#show config

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.
