Preprovisioning a Port
Before a port can be configured, the slot must be preprovisoned with an allowed card type and the
MDA must be preprovisioned with an allowed MDA type.
Some recommendations to configure a port include:
•Ethernet
→ Configure an access port for customer facing traffic on which services are configured.
An encapsulation type may be specified in order to distinguish services on the port or
channel. Encapsulation types are not required for network ports.
To configure an Ethernet access port, refer to on page 197.
• SONET/SDH
→ SONET/SDH can be used only when configuring an OC-3, OC-12, OC-48, OC-192,
and OC-768 SONET paths on an appropriate MDA.
To configure a SONET path, refer to Configuring SONET/SDH Port Parameters on
page 199.
Configure a network port or channel to participate in the service provider transport or
infrastructure network.
Accounting policies can only be associated with network ports/channels and Service
Access Ports (SAPs). Accounting policies are configured in the config>log>
accounting-policy context.
To configure an Ethernet network port, refer to on page 197.
• Channelized
→ Channelized ports can only be configured on channel-capable MDAs or CMAs such
as the channelized DS-3, channelized OC-3-SFP, channelized OC-12-SFP, or
channelized Any Service Any Port MDAs or CMAs.
