Assign An Ip Address To A Port Channel; Delete Or Disable A Port Channel - Dell Force10 S4810P Configuration Manual

Assign 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 in the INTERFACE mode:
Command Syntax
ip address
ip-address mask

Delete or disable a port channel

To delete a port channel, you must be in the CONFIGURA TION mode and use the
channel-number
When you disable a port channel (using the

Load balancing through port channels
FTOS uses hash algorithms for distributing traffic evenly over channel members in a port channel (LAG).
The hash algorithm distributes traffic among 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.
FTOS allows you to modify the hashing algorithms used for flows and for fragments. The
hash-algorithm
implementation are somewhat different between the E-Series and the C-Series and S-Series.
Note: Hash-based load-balancing on MPLS does not work when packet-based hashing (
