DLP-A222 Provision G-Series Ethernet Ports
DLP-A222 Provision G-Series Ethernet Ports
Step 1 In the 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—Select the service state for the port. See the “DLP-A214 Change the Service State for
a Port” task on page 19-9 for more information.
• 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-A421
Provision G-Series Flow Control Watermarks” task on page 21-7.
• 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). ISL adds 30 bytes of overhead and might
cause the frame size to exceed the traditional 1518 byte maximum.
Step 4 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.
Step 5 Click Apply.
Step 6 Refresh the Ethernet statistics:
a. Click the Performance > Statistics tabs.
b. Click Refresh.
Note Reprovisioning an Ethernet port on the G-Series card does not reset the Ethernet statistics for
that port.
Step 7 Return to your originating procedure (NTP).
Purpose This task provisions G-Series Ethernet ports to carry traffic.
