  39. Workshop Applications • During the workshop you will create several applications: • ETX‑5300A Out-of-Band (OOB) Management • E-Line – Ethernet Private Line Application • E-Line – Ethernet Virtual Private Line Application • E-LAN – In band Management from Central Location to Remote CPEs

  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.
