Ethernet Port Commands

Description This command enables access to the context to configure Ethernet port attributes.
This context can only be used when configuring Fast Ethernet, gigabit, or 10Gig Ethernet LAN ports
on an appropriate MDA.

Description This command configures an Ethernet port for access, network, or hybrid mode of operation. It also
configures a TDM channel or SONET/SDH path (sub-port) for access or network mode operation.
An access port or channel is used for customer facing traffic on which services are configured. A
Service Access Point (SAP) can only be configured on an access port or channel. When a port is
configured for access mode, the appropriate encap-type must be specified to distinguish the services
on the port or SONET path. Once an Ethernet port, a TDM channel or a SONET path has been
configured for access mode, multiple services can be configured on the Ethernet port, a TDM channel
or SONET path. Note that ATM, Frame Relay, and cHDLC port parameters can only be configured
in the access mode.
A network port or channel participates in the service provider transport or infrastructure network
when a network mode is selected. When the network option is configured, the encap-type cannot be
configured for the port/channel.
When network mode is selected on a SONET/SDH path, the appropriate control protocols are
activated when the need arises. For example, configuring an IP interface on the SONET path activates
IPCP while the removal of the IP interface causes the IPCP to be removed. The same applies for
MPLS, MPLSCP, and OSICP. When configuring a SONET/SDH port, the mode command must be
entered in the channel context or an error message is generated.
A hybrid Ethernet port allows the combination of network and access modes of operation on a per-
VLAN basis and must be configured as either dot1q or QinQ encapsulation.
