+## LACP / PortChannel
+
+You can find a example in [SONiC Command Line Interface Guide](https://github.com/sonic-net/sonic-utilities/blob/master/doc/Command-Reference.md#portchannels). If you're using this to connect to other switches and routers, make sure to set fallback to false (so that you don't make a L2 loop).
+
+If the PortChannel isn't showing up correcty, check if teamd feature is enabled and running:
+```
+(vrf:mgmt)root@sonic:~# show feature status teamd
+Feature    State    AutoRestart
+---------  -------  -------------
+teamd      enabled  enabled
+```
