On aggregated Ethernet interfaces, you can set the required link speed for all interfaces included in the bundle. All interfaces that make up a bundle must be the same speed. If you include in the aggregated Ethernet interface an individual link that has a speed different from the speed you specify in the link-speed parameter, an error message will be logged.

The speed value is specified in bits per second either as a complete decimal number or as a decimal number followed by the abbreviation k (1000), m (1,000,000), or g (1,000,000,000).

Aggregated Ethernet interfaces on SRX3000 and SRX5000 line devices can have one of the following speed values:

• 100m—Links are 100 Mbps.
• 10g—Links are 10 Gbps.
• 1g—Links are 1 Gbps.

Only on the following devices you might configuremixed rate of link speeds for the aggregated Ethernet bundle; link speeds of 10G, 40G, and 100G are supported.

• QFX5100
• QFX5120
• QFX10002 
• QFX5100 
• QFX5200 
• QFX5210 
• EX4600
   

On SRX4600 load balancing does not work if you configure link speeds that are not supported.

Configure link-speed as 10G.

NOTE: On QFX5100, QFX5120, EX4600, QFX10002 standalone switches, and on a QFX5100 Virtual Chassis and EX4600 Virtual Chassis, you can configure a mixed rate of link speeds for the aggregated Ethernet bundle. Link speeds of 10G, 40G, and 100G are supported. QFX5200 and QFX5210 switches support mixed link speeds. QFX5200 and QFX5210 switches also support load balancing with the mixed link speeds. Load balancing does not work if you configure link speeds that are not supported.
