Based on the Ethernet data Layer 2 switch function, EPLAN services allow the accessed data to be transported to its destination media access control (MAC) address. This section describes the method to set the EPLAN service.
It applies to the LEM18, 11LEX4, 11LEM24, L4G and TBE board.
The electrical cross-connect services between the Ethernet board and the OTU board supporting GE service grooming must be created.
Each Ethernet board must support at least one virtual bridge (VB).
One VB can be created in each Ethernet board in the system. Inside VBs, the MAC address learning function is used to complete the forwarding of Ethernet data. The MAC address table is updated periodically based on the address learning result.
Setting the parameters of a port affect the service of the board. Before setting the parameters of a port, configure State of the port as OOS at the Ethernet Interface. After setting the parameters, restore State of the port to IS.
.

Table 1 lists the main parameters involved in the configuration of EPLAN services.
| Field | Value | Description |
|---|---|---|
Board |
- |
Displays the name of the board. |
VB ID |
- |
Allocated automatically when an Ethernet LAN service is created. |
VB Name |
- |
Specifies a VB name that contains a maximum of 16 characters or numerals, or eight Chinese characters. |
VB Type |
802.1q, 802.1d, 802.1ad Default: 802.1q |
Sets the type of a bridge. |
Bridge Switch Mode |
|
Selects the bridge switch mode. By default, the bridge switch mode is the virtual bridge in the case of 802.1q or 802.1ad and is the pure bridge in the case of 802.1d. |
Bridge Learning Mode |
IVL, SVL Default: IVL |
Displays the bridge learning mode. Independent VLAN learning (IVL): Isolates MAC address during forwarding based on the VLAN tag. Shared VLAN learning (SVL): destination MAC address based forwarding and learning. |
Ingress Filter |
Enabled, Disabled |
Displays the status of an ingress filter of the port. It is not configurable. Enabled: Checks the validity of a VLAN ID on the basis of bridge. If the ingress receives a packet that does not belong to the VLAN associated to the port on the bridge, the ingress discards the packet. Disabled: Does not check the validity of a VLAN ID. All packets that want to enter the bridge are valid. |
MAC Address Learning |
Enabled, Disabled Default: Enabled |
Enables or disables MAC address learning. It is not configurable. Enabled: MAC addresses are dynamically learnt. Disabled: MAC addresses are statically configured. |
Table 2 provides the port mounting parameters.
| Field | Value | Description |
|---|---|---|
VB Port |
- |
Allocated automatically when the VB mount port is configured. |
Mount Port |
- |
Set the mount port. |
Port Type |
UNI, C-AWARE, S-AWARE Default: UNI |
Sets the network attributes for a port. If the port is of the UNI type, the port processes the TAG attributes in 802.1q and the port has the Tag Aware, Access and Hybrid attributes. If the port is of the C-AWARE type, the port does not process the tag attributes in 802.1q. It determines that the data packet carries no S-VLAN tag and processes only the data packet that has the C-VLAN tag. If the port is of the S-AWARE type, the port does not process the tag attributes in 802.1Q. It determines that the data packet carries the S-VLAN tag and processes only the data packet that has the S-VLAN tag. QinQ services support C-Aware and S-Aware ports. EPL services support only UNI ports. |
Port Enable |
Enabled, Disabled Default: Enabled |
Enables or disables a port. Enabled: This port can access services. Disabled: This port cannot access services. When the Mount Port is VCTRUNK port, Port Enable is Enabled by default. |
Hub/Spoke |
Hub, Spoken |
Sets the Hub/Spoke attribute of the port. Services are interoperable between a Hub port and a Spoken, or between two Hub ports, but not between two Spoke ports. |
TAG |
Tag Aware, Access, Hybrid |
TAG is used to set the type of the messages to be processed. The tag aware port only processes the messages with a tag, and those messages without a tag are discarded. However, the Access port is quite the contrary. The hybrid port processes the two types of messages. It adds a tag to the messages without a tag according to the VLAN ID of this port. |
Default VLAN |
|
Displays the ID of the default VLAN that passes through the port. |
Working Mode |
Auto-negotiation, 1000M Full_Dulex |
Sets the working mode of the port. For example: Auto-negotiation: The port can use a protocol to automatically find out the optimum working mode in which it communicates with its interconnected port. 10M Half_Dulex: The highest transmission rate of the port is 10 Mbit/s, and the communication mode is half-duplex. NOTE:
Currently, the 1000M Half_Dulex mode is not supported. |
Service Detection |
Bidirectional |
Displays the direction of services. |
C-VLAN |
|
Displays the C-VLAN value. |
S-VLAM |
|
Displays the S-VLAN value. |
