[output omitted]
In the previous example, several ports display “Auto” in the Speed field, 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.
Example of Setting Port Speed and Disabling Auto-Negotiation
FTOS#configure
FTOS(config)#interface tengig 0/1
FTOS(conf-if-te-0/1)#speed 100
FTOS(conf-if-te-0/1)#duplex full
FTOS(conf-if-te-0/1)#no negotiation auto
FTOS(conf-if-te-0/1)#show config

interface GigabitEthernet 0/1
no ip address
speed 100
duplex full
no shutdown
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
FTOS(conf)# int tengig 0/0
FTOS(conf-if-te-0/1)#neg auto
FTOS(conf-if-te-0/1)# ?
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
FTOS(conf-if-te-0/1)#
mode ?
forced-master Force port to master mode
forced-slave Force port to slave mode
FTOS(conf-if-te-0/1)#
For details about the speed, duplex, and negotiation auto commands, refer to the Interfaces chapter of the
FTOS Command Reference Guide .
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.
