Testing

To check LACP settings on the Cisco Switch side the used command “show ethernetchannel summary”

Switch#show etherchannel summary 
Flags:  D - down        P - in port-channel
        I - stand-alone s - suspended
        H - Hot-standby (LACP only)
        R - Layer3      S - Layer2
        U - in use      f - failed to allocate aggregator
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port


Number of channel-groups in use: 1
Number of aggregators:           1

In the above print, Gig0 / 1 (D) and Gig0 / 2 (D) ports need to be seen among the member ports.

For Antikor v2 LACP settings Antikor v2 LACP Configuration follow the documents.

From Cisco Switch to Antikor v2 sending ping;

Switch#ping 10.0.0.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.1, timeout is 2 seconds:
!!!!!
Success rate is 5 percent (5/5)

For Antikor v2 LACP settings Antikor v2 LACP Configuration follow the documents.
