Configuring the Port User Part of the Address
The port user part of an AESA address consists of the ESI and SEL portions of the
address. It is used for the DTE (user) ports on a Lucent switch and provides
information for the address table on the DCE device attached to the UNI on the public
network side (see “About Address Registration” on page 16-8). When the attached
DCE device receives prefixes, the user part(s) are concatenated to form full addresses.
The full addresses are then written back to the DCE device’s ILMI address table.
When you configure the port user part to complete an address connection with the
attached DCE device, you can supply any 7-octet value as the user part (it does not
have to be a real IEEE MAC address and SEL combination). Also, you should enter
any user addresses in your network that you want to make known to the attached
public network. To do this, collect Media Access Control (MAC) addresses from
attached devices and enter them as user parts at the public UNI port.
You may have to define user parts only on UNI DTE ports where the device attached
to that port expects address registration completion. That is, the attached device is
broadcasting its network prefixes to the Lucent port, and expects the Lucent switch to
respond with the user part of the address.
