Before a port can be configured, the slot must be preprovisioned 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 to distinguish services on the port or channel. Encapsulation types are not required for network ports.
To configure an Ethernet access port, see Ethernet access port.
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, see Configuring SONET/SDH port parameters.
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, see Ethernet network port.
Channelized
Channelized ports can only be configured on channel-capable MDAs, or TDM satellites such as the channelized DS-3, channelized OC-3-SFP, channelized OC-12-SFP, or channelized Any Service Any Port MDAs.
