41. Management Flow Configuration
There are several procedures for configuring management flow:
SVI (Switched Virtual Interface) – Defines a logical port used to associate the router interface with the remote device (peer).
Flow Classifications – Define the types of traffic.
Flow – Defines the In/Out paths.
Router Interface – Makes the ETX accessible from different access points. The router provides a logical path at L3.

51. Bridge Bridge Entity enables E-LAN services
Bridge ports may be bounded to physical port or to Logical port. Bridge port which is flow based should be bounded to SVI and connected to Physical ports with flows.
VLAN aware bridge, configure for each VLAN port membership list needed.
When a bridge port is bounded to a physical port or any of the logical ports except SVI, the forwarding to/from the BP and the Eth port will be done according to the VLAN membership. In case that the BP will be bounded to SVI, the forwarding to/from the BP and the SVI will be done through flows configuration.
