DLP- D222 Provision G-Series Ethernet Ports
DLP-D222 Provision G-Series Ethernet Ports
Step 1 In node view, double-click the G-Series card graphic to open the card.
Step 2 Click the Provisioning > Port tabs.
Step 3 For each G-Series port, provision the following parameters:
• Port Name—If you want to label the port, type the port name.
• Admin State—Complete the “DLP-D214 Change the Service State for a Port” task on page 19-10.
• Auto Negotiation—Click this check box to enable autonegotiation on the port (default). If you do
not want to enable autonegotiation control, uncheck the box.
• Flow Control—Click this check box to enable flow control on the port (default). If you do not want
to enable flow control, uncheck the box. To set custom flow control watermarks, see the “DLP-D353
Provision G-Series Flow Control Watermarks” task on page 20-58.
• Max Size—To permit the acceptance of jumbo size Ethernet frames, choose Jumbo (default). If you
do not want to permit jumbo size Ethernet frames, choose 1548.
Note The maximum frame size of 1548 bytes enables the port to accept valid Ethernet frames that
use protocols, such as Inter-Switch Link (ISL) protocol. ISL adds 30 bytes of overhead and
might cause the frame size to exceed the traditional 1518 byte maximum.
• Payload Type—Click in the Payload Type field and select a cyclic redundancy check (CRC) size to
set the G-Series card’s LEX encapsulation:
–
LEX-FCS-16 is 16-bit (2 byte) CRC.
–
LEX-FCS-32 is 32-bit (4 byte) CRC.
Note An Encapsulation Mismatch Path alarm appears when a point-to-point circuit is created between two
Ethernet card ports with incompatible Encapsulation payload types.
Step 4 Click Apply.
Step 5 Refresh the Ethernet statistics:
a. Click the Performance > Statistics tabs.
b. Click the Refresh button.
Purpose This task provisions G-Series Ethernet ports.
