Configuring LACP
LACP (Link Aggregation Control Protocol) is a network protocol defined in the IEEE 802.3ad standard. It is used to combine multiple physical links into a single logical link—known as a port channel or link aggregation group (LAG)—to increase bandwidth and provide redundancy
LACP Fallback: Enables the interface to fall back to standalone mode when LACP negotiation fails, ensuring continued traffic forwarding.
LACP Fast-Rate: Reduces the LACP negotiation interval to 1 second, allowing quicker detection of link status changes.
LACP Min-Links: Ensures the port-channel remains operational only when the minimum configured number of links are active, enhancing redundancy and stability.

Command
pbnoscli(config)# port-channel <channelid> ports <portname> lacp

<string>
fallback
<true/false>

minimum num of links
Example
pbnoscli# configure terminal
pbnoscli(config)# port-channel 1
ports Add physical ports to port channel
pbnoscli(config)# port-channel 1 ports
<portname> Add ports (Add multiple ports comma delimited)
pbnoscli(config)# port-channel 5 ports Ethernet1/1,Ethernet2/1 lacp
pbnoscli(config)# end
pbnoscli(config)# no port-channel 5 ports
<cr>
You can verify the configuration by using the command(s) below:
pbnoscli# show port-channel information
Flags: A - active, I - inactive, Up - up, Dw - Down, N/A - not available,
S - selected, D - deselected, * - not synced
