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.

Configure 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 configure up to eight secondary IP addresses.

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.

When you disable a port channel, all interfaces within the port channel are operationally down also.

Dell Networking OS uses hash algorithms for distributing traffic evenly over channel members in a port channel (LAG).

The hash algorithm distributes traffic among Equal Cost Multi-path (ECMP) paths and LAG members. The distribution is based on a flow,

except for packet-based hashing. A flow is identified by the hash and is assigned to one link. In packet-based hashing, a single flow can be

distributed on the LAG and uses one link.

Packet based hashing is used to load balance traffic across a port-channel based on the IP Identifier field within the packet. Load balancing

uses source and destination packet information to get the greatest advantage of resources by distributing traffic over multiple paths when

transferring data to a destination.
