Port Speed on EX Series Switches
Learn supported port speeds, channelization, and interface naming conventions of EX Series switches.
EX Series switches support a mix of speeds from 10 Mbps up to 100 Gbps depending on the model and port type, with many models supporting multi-gigabit speeds (2.5 Gbps, 5 Gbps) on copper ports and 10/25/40/100 Gbps on fiber or QSFP ports. Port speeds can often be configured or negotiated based on network requirements.
Note the following about port speeds on EX Series Switches:
-
For information about platform support of all EX Series Switches, see Hardware Compatibility Tool (HCT).
-
1 G SFP-T port with 100 Mbps configuration using
set interfaces <interfaces-name> speed 100moperates only in 100 Mbps speed on EX Series Switches. If there is a link partner with speed other than 100 Mbps for the above 1 G SFP-T port with 100 Mbps configuration, the link does not come up. The same is applicable for 10 Mbps configuration on 1 G SFP-T port.

Use the speed command to set the speed on tri-rate copper SFP port. For information about how to configure the speed at the chassis level, see Table 1. For information about how to configure the speed at the interfaces level, see Table 2.
EX4650-48Y does not support autonegotiation when 1-gigabit fiber SFP transceiver is plugged in. In such cases, we recommend to disable auto-negotiation on the remote end device. But, EX4650-48Y switches with 1-gigabit copper SFP transceiver supports autonegotiation, as the physical layer within the transceiver handles autonegotiation.

Note the following guidelines for EX4400-24X switches:
-
You can configure PIC 1 port 0 in 100 GbE virtual chassis mode and port 1 in 100GbE network mode simultaneously and vice versa.
-
You can configure PIC 1 port 0 in 40 GbE virtual chassis mode and port 1 in 40 GbE network mode simultaneously and vice versa.
-
You can channelize 100GbE ports into 4x25G network ports and 40GbE network ports into 4x10G.
-
Virtual chassis ports do not support channelization.
-
When you change the speed of port 0 to 1 GbE, 10GbE, or 25 GbE in PIC 2, all the four ports change to the same speed.

The maximum MTU size supported on EX4100 switches is 9216 bytes. Packets above MTU+8 bytes are marked as oversized frames and the packets between MTU+4 and MTU+8 bytes with invalid errors.
Virtual Chassis Ports and Network Ports
You can use the request virtual-chassis mode network-port
command to enable network port mode, which converts the default VCPs on the
switch into network ports. After executing this command, you must reboot the
switch for this command to take effect.
To disable network port mode and return these ports to their default settings
as VCPs, use the network-port and disable options with the request
virtual-chassis mode command. You must reboot the switch for
network port mode changes to take effect, so you can include the reboot
option in the same command. For example:
request virtual-chassis mode network-port disable reboot
The following are some of the guidelines for configuring the VCPs:
- The default speed of VCPs in EX4100-48P, EX4100-48T, EX4100-24P, EX4100-24T, EX4100-24MP, and EX4100-48MP switches is 4x25G. You can convert the VCPs of these switches to network ports that operates at the speed of 25G, 10G, and 1G. You can configure the network ports in mixed speed. For example, port 0 with 1x25G, port 1 with 1x10G, and ports 2 and 3 with 2x1G.
- The default speed of VCPs in EX4100-F-48P, EX4100-F-48T, EX4100-F-24P, EX4100-F-24T, EX4100-F-12P, and EX4100-F-12T switches is 4x10G. You can convert the VCPs of EX4100-F-48P, EX4100-F-48T, EX4100-F-24P, EX4100-F-24T, EX4100-F-12P, and EX4100-F-12T switches to network ports that operates at the speed of 4x10G or 4x1G. The ports work either as VCPs or network ports, where mixed mode is not supported. But you can configure the network ports in mixed speed. For example, port 0 with 1x10G, port 2 with 1x10G, and ports 2 and 3 with 2x1G.
-
The EX4100 switches support HiGig over Ethernet (HGoE) mode. HGoE enables mixed mode operation where you can configure some ports as VCPs and other ports as standard network ports. HGoE is also the default VC mode for EX4100-H switches. The HGoE mode provides flexibility in network configuration.
- In the EX4100 switches family, we support 1G speed on PIC1 in network mode only and not as a virtual chassis port.

Follow these guidelines when you configure the port speed:
-
You must configure applicable speeds on mge interfaces. Unsupported speeds do not reflect on the link speed of interfaces.
-
Only network mode supports 1 Gbps on PIC 1. Virtual chassis (VC) mode does not support 1 Gbps.
-
Always enable flow control on MACsec configured ports. Packets above MTU+8 bytes are marked as oversized frames and dropped.
-
Supports maximum MTU size of 9216 bytes.
-
