Link Aggregation
Link aggregation provides a method for aggregating two or more 1 Gigabit ethernet links into a single logical link known as
a Link Aggregation Group (LAG):
Benefiting from larger capacity links without the costs of 10 Gigabit interfaces
Reducing the number of IP/IPv6 addresses required per chassis
Reducing the number of interfaces to be configured.
LAGs can also help operators manage their data networks. They do this by:
Dynamically bringing down a link-aggregate if the number of its operational ports falls below a certain level as defined
by the min-links configuration
Using Link-Aggregation Control Protocol (LACP) to detect bad configurations between the C4/c CMTS and its neighbors
Increase fault tolerance by allowing the bundling of interfaces from both RCMs.
Provisioning
Operators provisioning ports and configuring LAGs should be aware of the following:
The C4/c CMTS does not support dynamic formation of LAGs; they must be manually provisioned by the operator.
All member ports of a link-aggregate must be connected to the same partner (remote) system.
TenGigabit interfaces are not allowed to be members of a LAG.
