Configuring the Port Type on QFX3600 Standalone Switches
The QFX3600 standalone switch provides 16 40-Gbps QSFP+ ports. By default, all 16 ports operate as 40-Gigabit Ethernet (xle) ports. Optionally, you can choose to configure the 40-Gbps ports to operate as four 10-Gigabit Ethernet (xe) ports. 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 servers, storage, and switches.
 | Note: Port Q0 supports only three (not the typical four) 10-Gigabit Ethernet ports, because one port is reserved. Therefore, you can configure up to 63 (not 64) 10-Gigabit Ethernet ports on ports Q0 through Q15. |
This topic explains how to configure the port type on QFX3600 standalone switches.
 | Caution: The Packet Forwarding Engine on the QFX3600 standalone switch is restarted when you commit the port type configuration changes. As a result, you might experience packet loss on the switch. 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 |
The following steps describe how to configure either a block of ports or an individual port to operate as 10-Gigabit Ethernet (xe) ports, as well as how to delete a 10-Gigabit Ethernet (xe) port configuration.
| Note: When you delete the xe port type configuration for an individual port or a block of ports, the ports return to operating as 40-Gigabit Ethernet (xle) ports. |
- To configure a block of ports to operate as 10-Gigabit
Ethernet (xe) ports, specify a port range:
For example, to configure ports Q4 through Q7 to operate as 10-Gigabit Ethernet ports:
[edit chassis fpc 0 pic 0]user@switch# set xe port-range 4 7 - To configure an individual port to operate as a 10-Gigabit
Ethernet (xe) port, specify a port number:[edit chassis fpc 0 pic 0]user@switch# set xe port port-number
For example, to configure port Q4 to operate as a 10-Gigabit Ethernet port:
[edit chassis fpc 0 pic 0]user@switch# set xe port 4 - Review your configuration and issue the commit command.[edit chassis fpc 0 pic 0]user@switch# commitcommit complete
- To delete the 10-Gigabit Ethernet (xe) port configuration
for a block of ports (and return to the default 40-Gigabit Ethernet
configuration), specify a port range:[edit chassis fpc 0 pic 0]user@switch# 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 fpc 0 pic 0]user@switch# delete xe port-range 4 7 - To delete the 10-Gigabit Ethernet (xe) port configuration
for an individual port (and return to the default 40-Gigabit Ethernet
configuration), specify a port number:[edit chassis fpc 0 pic 0]user@switch# delete xe port port-number
For example, to delete the 10-Gigabit Ethernet port configuration for port Q4:
[edit chassis fpc 0 pic 0]user@switch# delete xe port 4
