I will give an example of configuring LAG (LACP) on a Cisco Nexus 3064.
First of all, let’s enable the feature lacp:
At the time of writing, I needed to configure LACP (LAG) between Cisco Nexus 3064 and Cisco Nexus 3048TP in order to expand UPLINK to 20 Gb/s.
I added ports to port-channel:
interface Ethernet1/43-44 speed 10000 no negotiate auto duplex full channel-group 1 mode active
And then I configured the port-channel itself:
interface port-channel 1 description LAG1_UPLINK switchport access vlan 2 end
This completes the LACP configuration on the Cisco Nexus 3064, similarly you can configure on other Cisco Nexus switches.
Let’s save the configuration:
copy running-config startup-config
Make sure that “Input flow-control is off, output flow-control is off” (by default it turns off automatically):
show interface Ethernet1/43-44 show interface port-channel 1
Otherwise, turn it off so that later delays and traffic limitation do not appear:
no flowcontrol receive no flowcontrol send
I will give an example of viewing various information and statistics:
show lacp port-channel show lacp counters show lacp internal info show lacp internal mem-stats show lacp internal event-history ? show lacp internal event-history errors show lacp internal event-history interface ethernet 1/48 show logging | include 1/48 show logging | include port-channel
