Configuring the Port Type on QFX3600 Node Devices

The QFX3600 Node device provides 16 40-Gbps QSFP+ ports. By default, four ports (labeled Q0 through Q3) operate as 40-gigabit data plane (fte) uplink ports for uplink connections between your Node device and your Interconnect devices. Twelve ports (labeled Q4 through Q15) operate as 10-Gigabit Ethernet (xe) ports to support 48 10-Gigabit Ethernet interfaces for connections to either endpoint systems or external networks. Optionally, you can choose to configure ports Q0 through Q7 to operate as 40-gigabit data plane uplink ports, and ports Q2 through Q15 to operate as 10-Gigabit Ethernet ports.

Note: You can use QSFP+ to four SFP+ breakout cables or QSFP+ transceivers with fiber breakout cables to connect the 10-Gigabit Ethernet ports to other devices.

Note: When you delete the port type configuration for an individual port or a block of ports, the ports return to operating in their default port type.

This topic explains how to configure the port type on QFX3600 Node devices.

Before you configure the port type on QFX3600 Node devices:

• Make sure your QFabric system is operational.
• Issue the show fabric administration inventory node-groups command to display the existing Node groups and the Node devices in each Node group.

Only ports Q0 through Q7 can be configured to operate as 40-gigabit data plane (fte) uplink ports. Only ports Q2 through Q15 can be configured to operate as 10-Gigabit Ethernet (xe) ports.

Caution: The Packet Forwarding Engine on the QFX3600 Node device is restarted when you commit the port type configuration changes. As a result, you might experience packet loss on the Node device. The following message may be displayed in the system log file when the Packet Forwarding Engine is restarted. You can ignore this message. Pipe write error: Broken pipe flush operation failed

1. To configure a block of ports to operate as 40-gigabit data plane uplink (fte) ports, specify a port range:
   [edit chassis node-group name node-device name pic 1]root@qfabric# set fte port-range port-range-low port-range-high

   For example, to configure ports Q4 through Q7 to operate as 40-gigabit data plane uplink ports:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 1]root@qfabric# set fte port-range 4 7
2. To configure an individual port to operate as a 40-gigabit data plane uplink (fte) port, specify a port number:
   [edit chassis node-group name node-device name pic 1]root@qfabric# set fte port port-number

   For example, to configure port Q4 to operate as a 40-gigabit data plane uplink port:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 1]root@qfabric# set fte port 4
3. Review your configuration and issue the commit command.
   [edit]root@qfabric# commitcommit complete
4. To delete the 40-gigabit data plane uplink (fte) port configuration for a block of ports, specify a port range:
   [edit chassis node-group name node-device name pic 1]root@qfabric# delete fte port-range port-range-low port-range-high

   For example, to delete the 40-gigabit data plane uplink port configuration for ports Q4 through Q7:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 1]root@qfabric# delete fte port-range 4 7
5. To delete the 40-gigabit data plane uplink (fte) port configuration for an individual port, specify a port number:
   [edit chassis node-group name node-device name pic 1]root@qfabric# delete fte port port-number

   For example, to delete the 40-gigabit data plane uplink port configuration for port Q4:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 1]root@qfabric# delete fte port 4

1. To configure a block of ports to operate as 10-Gigabit Ethernet (xe) ports, specify a port range:
   [edit chassis node-group name node-device name pic 0]root@qfabric# set xe port-range port-range-low port-range-high

   For example, to configure ports Q4 through Q7 to operate as 10-Gigabit Ethernet ports:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 0]root@qfabric# set xe port-range 4 7
2. To configure an individual port to operate as a 10-Gigabit Ethernet port, specify a port number:
   [edit chassis node-group name node-device name pic 0]root@qfabric# set xe port port-number

   For example, to configure port Q4 to operate as a 10-Gigabit Ethernet port:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 0]root@qfabric# set xe port 4
3. Review your configuration and issue the commit command.
   [edit]root@qfabric# commitcommit complete
4. To delete the 10-Gigabit Ethernet (xe) port configuration for a block of ports, specify a port range:
   [edit chassis node-group name node-device name pic 0]root@qfabric# delete xe port-range port-range-low port-range-high

   For example, to delete the 10-Gigabit Ethernet port configuration for ports Q4 through Q7:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 0]root@qfabric# delete xe port-range 4 7
5. To delete the 10-Gigabit Ethernet (xe) port configuration for an individual port, specify a port number:
   [edit chassis node-group name node-device name pic 0]root@qfabric# delete xe port port-number

   For example, to delete the 10-Gigabit Ethernet port configuration for port Q4:

   [edit chassis node-group BBAK8281 node-device BBAK8309 pic 0]root@qfabric# delete xe port 4
