Configuring Switch 3:
On
Switch 3
, LACP is enabled in active mode on interfaces 1/1/3 and 1/1/4, as an aggregated
link to Switch 1.
1. Enter into Protocol Configuration mode and enable the LACP on switch 3:
Switch3
#
configure terminal
Switch3
(config)#
protocol
Switch3
(cfg protocol)#
link-aggregation lacp enable
Switch3
(cfg protocol)#
end
2. Display the LACP configuration:
Switch3
#
show link-aggregation lacp
System ID = 00 a0 12 10 94 c0
System priority = 32768
No LAC ports configured
3. Enable LACP on interfaces 1/1/3 and 1/1/4:
Switch3
#
configure terminal
Switch3
(config)#
interface 1/1/3
Switch3
(config-if 1/1/3)#
link-aggregation lacp
Switch3
(config-if 1/1/3)#
interface 1/1/4
Switch3
(config-if 1/1/4)#
link-aggregation lacp
Switch3
(config-if 1/1/4)#
end
4. Display the LACP configuration:
Switch3
#
show link-aggregation lacp
System ID = 00 a0 12 10 94 c0
System priority = 32768
