Assigning an IP Address to a Port Channel
You can assign an IP address to a port channel and use port channels in Layer 3 routing protocols.
To assign an IP address, use the following command.
• Congure an IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
– ip-address mask: enter an address in dotted-decimal format (A.B.C.D). The mask must be in slash format (/24).
– secondary: the IP address is the interface’s backup IP address. You can congure up to eight secondary IP addresses.
Deleting or Disabling a Port Channel
To delete or disable a port channel, use the following commands.
• Delete a port channel.
CONFIGURATION mode
no interface portchannel channel-number
• Disable a port channel.
shutdown
When you disable a port channel, all interfaces within the port channel are operationally down also.
Load Balancing Through Port Channels
Dell EMC Networking OS uses hash algorithms for distributing trac evenly over channel members in a port channel (LAG).
The hash algorithm distributes trac among Equal Cost Multi-path (ECMP) paths and LAG members. The distribution is based on a ow,
except for packet-based hashing. A ow is identied by the hash and is assigned to one link. In packet-based hashing, a single ow can be
distributed on the LAG and uses one link.
Packet based hashing is used to load balance trac across a port-channel based on the IP Identier eld within the packet. Load balancing
uses source and destination packet information to get the greatest advantage of resources by distributing trac over multiple paths when
transferring data to a destination.
