speed (Chassis Cluster)



The SRX4600 supports three different PIC types—8-port 10-Gigabit Ethernet PIC, 4-port 40-Gigabit or 100-Gigabit Ethernet PIC, and 4-port 10-Gigabit Ethernet PIC (in a chassis cluster). Out of the four ports on the 10-Gigabit Ethernet PIC in a chassis cluster, two ports are fabric ports and the other two ports are chassis cluster control ports. The two fabric ports do not support 1-Gbps speed. Only the two control ports of the chassis cluster support a port speed of 1 Gbps. When you replace a node through return merchandise authorization (RMA), set the speed and reboot the node to activate the control-link.

On chassis cluster control interfaces, you can configure the operating speed of the 4-port 10-Gigabit Ethernet PIC from default 10-Gbps port speed to 1-Gbps port speed. You must reboot the device for the changed configuration to take effect.

The chassis cluster control interfaces do not support multiple speeds.

Following are the list of optics supported on SRX4600:





Autonegotiation is automatically disabled when 1-Gbps speed is configured on the interfaces.

  • The interface name for any xe interface remains same after converting its speed from 10G to 1G.

  • To view the speed configured for the interface, execute the show interfaces extensive command. The Speed Configuration field's value of 1G or AUTO in the command output indicates whether the current operation speed of the interface is 1 Gbps or the default 10 Gbps, respectively.


  • 1g — Link speed of 1 Gbps

  • 10g — Link speed of 10 Gbps
