Continuando con etherchannel, vamos a ver como montarlo contra un router y ademas que soporte enrutamiento de VLAN en esquema router on a stick.
Configuracion del switch:
Cat2950(config)# interface port-channel 1
Cat2950(config-if)# exit
!— Asignamos puertos al canal logico para formar el EtherChannel.
Cat2950(config)# interface fa0/2
Cat2950(config-if)# channel-group 1 mode on
Cat2950(config-if)# exit
Cat2950(config)#
00:25:38: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up
00:25:39: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed
state to up
Cat2950(config)# interface fa0/3
Cat2950(config-if)# channel-group 1 mode on
Cat2950(config-if)# exit
!— Ahora ponemos el etherchannel como troncal y al igual
!— que los troncales tradicionales configuramos la VLAN nativa
Cat2950(config)# interface port-channel 1
Cat2950(config-if)# switchport mode trunk
Cat2950(config-if)#
