After a default reset, the Passport 4400 automatically creates a PANL-DTE netlink. This netlink is called the Primary Netlink, and the port carrying the primary netlink is called the primary port. See Managing Primary and Backup Ports for more information about primary ports. See the figure below for an example of a Primary Netlink.
