Description This command configures an Ethernet port, TDM channel, or SONET/SDH path (sub-port) for access, net-
work or hybrid 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, multi-
ple 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 net-
work 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.
