menu path you can configure S4224 Ethernet services in
terms of ports, bandwidth profiles, EVCs (Ethernet Virtual Circuits) and ECEs (EVC Control Entries).
These pages configure Ethernet Virtual Connections (EVCs) and their configurations using the ECEs.
The MEF standards describe services provided to customers at User Network Interfaces (UNIs). Inside
provider networks, nodes are connected using Internal Network-to- Network Interfaces (I-NNIs).
Connections between service providers are done using External Network-to-Network Interfaces (E-NNIs).
An Ethernet Virtual Connection (EVC) is an association of two or more UNIs. Three EVC types are
defined:
E-Line: Point-to-point connection of two UNIs.
E-LAN: Multipoint-to-multipoint connection of two or more UNIs.
E-Tree: Rooted-multipoint connection between leaf and root UNIs. Frames are not forwarded
between leaf UNIs.
The MEF defines a number of attributes associated with a UNIs and EVCs. These attributes include
mappings of customer VLAN IDs to EVCs, ingress bandwidth profiles, processing of L2 control protocols
(L2CP) etc.
The S4224 EVC (Ethernet Virtual Connection) commands let you configure S4224 Ethernet services in
terms of EVCs and ECEs (EVC Control Entries). Only Provider Bridge based EVCs are supported on the
S4224.
The EVC is an association of two or more UNIs that limits the exchange of frames to UNIs in the Ethernet
Virtual Connection. The User Network Interface (UNI) is the physical interface or port that is the
demarcation between the customer and the service provider / Cable Operator /Carrier / MSO. The UNI is
the physical demarcation point between the responsibility of the Service Provider and the responsibility of
the Subscriber.
EVC
(Ethernet Virtual Connection): An association of two or more UNIs that limits the exchange of frames
to UNIs in the EVC. Generally, an EVC allows Ethernet service frames to be exchanged between UNIs
that are connected via the same EVC.
ECEs
(EVC Control Entries): Unique ECE IDs are automatically assigned to ECEs added. The possible
range is from 1 through 128. The ECE ID identifies the ECE.
Note
: You must set up an EVC before trying to set up a related ECE.
An Ethernet Services configuration procedure will include:
1. EVC Configuration
2. ECE Configuration
3. VLAN Configuration
4. MEP Configuration Procedure
a. Down MEP Configuration
b. Up MEP Configuration
c. Fault Management Configuration
5. EPS Configuration Procedure
