#port_channel_load_balance ⇒ Object

port-channel load-balance is a complicated command and this has so many forms in the same device and in different devices. For ex: port-channel load-balance src-dst ip rotate 4 concatenation symmetric port-channel load-balance resilient port-channel load-balance ethernet destination-mac CRC10c port-channel load-balance ethernet source-ip port-channel load-balance dst ip-l4port rotate 4 asymmetric port-channel load-balance dst ip-l4port-vlan module 9 port-channel load-balance hash-modulo we need to eliminate all the clutter and get the correct line of config first and after that get index of each property and get the property value because some properties may or may not be present always. This method returns a hash
