LACP enables ports to dynamically bundle as members of a port-channel. To congure a port for LACP operation, use the channel-
group mode {active|passive} command. Active and Passive modes allow LACP to negotiate between ports to determine if they
can form a port channel based on their conguration settings.
OS10(config)# interface port-channel 100
OS10(conf-if-po-100)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# channel-group 100 mode active
Minimum links
Congure minimum links in a port-channel LAG that must be in oper up status to consider the port-channel to be in oper up status.
NOTE:
If the minimum links criteria that you have congured is not met, the port channel operationally goes down only in the device in which
you have congured the minimum links and not on the device at the other side of the port channel.
For the port channel to go down operationally on both sides when the minimum links criteria is not met, you must congure minimum
links on both sides of the port channel.
Enter the number of links in a LAG that must be in oper up status in PORT-CHANNEL mode, from 1 to 32, default 1.

Congure minimum operationally up links
OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# minimum-links 5
Assign Port Channel IP Address
You can assign an IP address to a port channel and use port channels in L3 routing protocols.
• Congure an IP address and mask on the interface in INTERFACE PORT-CHANNEL mode.
ip address ip-address/mask [secondary-ip-address]
– ip-address/mask — Specify an IP address in dotted-decimal A.B.C.D format and the mask.
– secondary-ip-address — Specify a secondary IP address in dotted-decimal A.B.C.D format, which acts as the interface’s
backup IP address.
Assign Port Channel IP Address
OS10# configure terminal
OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# ip address 1.1.1.1/24
OS10(conf-if-po-1)#
Remove or disable port-channel
You can delete or disable a port-channel.
1 Delete a port-channel in CONFIGURATION mode.
no interface port-channel channel-number
2 Disable a port-channel to place all interfaces within the port-channel operationally down in CONFIGURATION mode.
