7.6. Channels
If you click the Channels tab on the top navigation bar, the Channels category and links appear.
The pages in the Channels category enable you to view and manage the channels and packages
associated with your systems. In addition, you can obtain ISO images here.

7.6.1. Software Channels

The Software Channels page is the first to appear in the Channels category. A software channel is a
list of Red Hat Enterprise Linux packages grouped by use. Channels are used to choose packages to
be installed on a system.
There are two types of software channels: base channels and child channels.
7.6.1.1. Base Channels
A base channel consists of a list of packages based on a specific architecture and Red Hat Enterprise
Linux release. For example, all of the packages in Red Hat Enterprise Linux 5 for the x86 architecture
make up a base channel. The list of packages in Red Hat Enterprise Linux 5 for the Itanium
architecture make up a different base channel.
A system must be subscribed to one base channel only. This base channel is assigned automatically
during registration based upon the Red Hat Enterprise Linux release and system architecture selected.
In the case of public free channels, the action will succeed. In the case of paid base channels, this
action will fail if an associated entitlement does not exist.
7.6.1.1.1. Extended Update Support (EUS)
In addition to base channels for major versions of Red Hat Enterprise Linux, there are channels for
update versions of Red Hat Enterprise Linux, which are also separated by architecture and which
can have child channels. These Extended Update Support (EUS) channels are for administrators
who want to stay with one major or update version of Red Hat Enterprise Linux and customize their
package updates for their particular version, rather than upgrade their systems to a new update
version that installs new software, hardware drivers, and features on production systems.
