Te 1/7 Up Te 1/8 Down Te 1/9 Down Te 1/10 Down Te 1/11 Down Te 1/12 Down [output omitted] 1000 Mbit Auto Auto Auto Auto Auto Auto Auto Auto Auto Auto Auto 1502,1504,1506-1508,1602 ------ In the previous example, several ports display "Auto" in the Speed field. In the following example, the speed of port 1/1 is set to 100Mb and then its auto-negotiation is disabled. Dell#configure Dell(config)#interface tengig 1/1 Dell(conf-if-te-1/1)#speed 100 Dell(conf-if-te-1/1)#duplex full Dell(conf-if-te-1/1)#no negotiation auto Dell(conf-if-te-1/1)#show config ! interface TenGigabitEthernet 1/1 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 autonegotiation 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 Dell(conf)# int tengigabitethernet 1/1 Dell(conf-if-te-1/1)#neg auto Dell(conf-if-te-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-te-1/1-autoneg)#mode ? forced-master Force port to master mode forced-slave Force port to slave mode Dell(conf-if-te-1/1-autoneg)# For details about the speed, duplex, and negotiation auto commands, refer to the Interfaces chapter of the Dell Networking OS 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. • Change the default interval between keepalive messages. INTERFACE mode keepalive [seconds] • View the new setting. INTERFACE mode Interfaces 391
