This case is provided to illustrate how to configure L2 LCAS 100M Ethernet Service. Here the 4×FE/C board is used as an example to show how to configure this service.
Step 1: Set Bridge’s property of NE
Right-click the data board card (such as 4× FE/C), and select <Bridge Configuration> in the pop-up menu. (See Fig. 19.5). The <Bridge Properties> window will appear. Note: If user click the port, the right-click menu will be different.
(See Fig. 19.6)
Fig. 19.5 Bridge Configuration Menu
Fig. 19.6 Bridges Properties
In the <Bridge Mode> field, there are two options: <Double Tag> (default value) and <IEEE 802>. Generally, <Double Tag> is chosen. If the double tag mode is chosen, PVID must be set on LAN ports. (Refer to Step 2).
Step 2: Configure LAN port of NE
Select <LAN Ports Property Configuration> in Fig. 19.5, the corresponding window will appear (see Fig. 19.7). Since there are many LAN ports in every data card, click <Port> in the top right corner of the window, and then select the corresponding port in the drop-down menu (the first LAN port is chosen in the example).
Fig. 19.7 LAN Port Configuration
The parameters that usually need to set are as follows:
<PVID>: Add a private VLAN mark to the signal from the LAN port. The optional value is from 1 -- 4094. If the double tag mode is chosen in step 1, the PVID must be set on LAN ports.
<Monitored Mode> – Can be set as <Auto>, <Monitor>, or <Non-Monitor>.
<Admin Mode> – Can be set as <Enabled> or <Disabled>.
<Egress Tag Mode> – Can be set as <Untag> or <Tag>.
Check <BRL Enable> to make the BRL available.
In the <Auto-Negotiation Parameter> section, if selecting <Enable> in the <Auto Negotiation>
field, the other three parameters will turn grey. If not, setup these three parameters manually.
Click <Apply> and <Close> to complete the LAN port configuration.
Step 3: Configure WAN port of NE
Right-click a card and select <WAN Ports Property Configuration> in the pop-up menu (See Fig. 19.5), the <WAN Port Config> window will appear. (See Fig. 19.8). Since there are many WAN ports in every data card, the port can be selected in the <Port> drop-down menu.
Fig. 19.8 WAN Port Config
The following parameters need to be set:
<PVID>: Add a private VLAN mark to the signal gotten from WAN port. The optional value is from 1 -- 4094.
<Egress Tag Mode>: There are two optional values: <Untag> and <Tag>. It is suggested that the default tag mode is chosen, which makes sure that additional PVID can be mapped to the load of SDH when the signals leave the data card from WAN port.
<BandWidth Management>: Select the <LCAS Enable> mode. There are two options: <LCAS Enable> and <LCAS Disable>. Select <Enable LCAS> to enable the Ethernet’s traffic
bandwidth user requires to be adjusted flexibly according to the network.
When the BandWidth configuration mode is confirmed, click <Bandwidth Management> to assign the capacity of WAN port. The <Bandwidth Configuration> window will appear. (See Fig. 19.9).
Fig. 19.9 Bandwidth Configuration
There are two options in the <Direction Config> field: <bi-direction>t and <uni-direction>.
<Bi-direction> means configuration to both source and destination, which is the mainly application. <Uni-direction> means source and destination configuration respectively.
The slots in the optional AUG in the left side are idle (the slots which haven’t been taken);
however the slots shown in the right side are the slots configured to this WAN port. Select 46 AUGs in the left side, and click the ==> button to add the slots used by those ports to WAN port. To decrease the number of slots used by this port, select corresponding slots in the right side and click the <== button.
Click <Apply> to confirm setting.
Click <OK> to close this window and return to the <WAN Port Config> window.
Click <Apply> and <Close> to complete the WAN port configuration.
Step 4: Set VLAN management of NE
PVIDs can be set to pass the WAN port through VLAN management. If the double tag mode is chosen in step 1, PVID must be set on LAN ports.
Right-click a card and select <VLAN Management> in the pop-up menu (See Fig. 19.5), the VLAN Management> window will pop up. (See Fig. 19.10)
Fig. 19.10 VLAN Management
Click <VLAN Config>, and then VLAN Config menu will pop up. (see Fig. 19.11)
Fig. 19.11 VLAN Config
There are two ways to modify VLAN: Based on VLAN and Based on Ports.
If the user wants to configure multiple ports with the same VLAN ID, the Based on VLAN mode is recommended. If the user wants to configure a port with multiple VLAN IDs, the Based on Ports mode is recommended. Here the Based on VLAN mode is chosen for an example.
Select the configured WAN port from the <Available Ports> list on the left side, click the ==>
button to move it to the <Selected Ports> list. Input the VLAN ID configured for selected port in the <VLAN ID> field. The value range of VLAN ID is from 0 to 4095, which is divided with eight subsections in every 512 IDs and only one section is effective at the same time, which means if a VLAN ID belonged to one of the above 8 ranges, other VLAN IDs belonged to other ranges can not be configured again. But among the range, 0, 1001-1024,4095 are reserved by system and not used by customer. Enter the VLAN name in the <VLAN Name>
field for the sake of remembrance.
Click <Apply> to confirm the changes.
Click <Close> to close the window.
Note: To query the VLAN ID of all the ports of data unit, click <Query> in the <VLAN Management> window. (See Fig. 19.12). The detail information will appear.

Step 5: Create Cross Connection
After all setting about Ethernet, a cross connection between SDH port and Ethernet port should be created.
To open the <Cross-Connect Management> window, select
<Configuration>→<Cross-Connect Management> from the main menu, or select the cross-connect and synchronize unit board in the Chassis View, right-click it, then select
<Cross-Connect Management> in the pop-up menu.
Click <Create>, and then the <Create Cross-Connect> window will appear.
Select the property of the cross connection to be created in this drop-down menu: <Capacity>
is <VC-12>; <Direction> is <Bi-Direction>; source card is #1<MainBoard(2×STM-1+8×E1)>;
source port is P01(S1); destination card is #2<4×FE/C)>; destination port is vP01(S1). Select 46 slots in left and 46 slots of WAN port configured in step1.
Fig. 19.13 Create Cross-Connect
Click <Apply> to create those Cross Connections. Click <OK> to close this window. Those Cross Connections will be listed in the <Cross-Connect Management> window. (See Fig.
19.14) The layer2 Ethernet service is configured successfully. Click <Close> to close
<Cross-Connect Management> window.
