Extension Module Ports

EX2300-24MP has four 10GbE extension module ports and EX2300-48MP has six 10GbE extension module ports. The extension module ports support SFP and SFP+ transceivers.

Virtual Chassis Ports

You can use the extension module ports as network ports or VC ports. You can connect up to four EX2300 switches by using SFP+ transceivers to form a VC.

Note the following guidelines for EX2300 switches:

  • EX2300 switches are available with or without PoE/PoE+ capability. Models that support PoE/PoE+ provide that support on all RJ-45 network ports.

  • Supports multi-rate Ethernet over existing cabling infrastructure.

Extension Module Ports

EX3400 switches have extension module ports that you can use to:

  • Interconnect member switches of a Virtual Chassis (VC).

  • Connect an access switch to a distribution switch.

The extension module ports on the front panel are configured as network ports by default. To use the extension module ports as VC ports, configure the ports as VC ports. See Configuring an EX2300, EX3400, EX4100, EX4100-F, EX4300, or EX4400 Virtual Chassis.

The QSFP+ extension module ports are configured as VC ports by default. To use the QSFP+ ports as network ports, configure the ports as network ports.

Virtual Chassis Ports

You can interconnect a maximum of 10 EX3400 switches to form a VC. You can use the following ports to form VC:

  • QSFP+ ports configured as VC ports.

  • Extension module ports on the front panel that is configured as VC ports by using SFP+ transceivers.

Power Over Ethernet (PoE) Ports

Note the following guidelines for EX3400 switches:

  • All RJ45 ports support PoE or PoE+.

Auto speed detection mode (Enabled by default)

If you have disabled auto-channelization, then to channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10GbE or 25GbE If a 100-Gigabit Ethernet transceiver is connected, you can only set the speed to 25GbE For the SFP+ ports, you can set the speed to 25GbE or 1 G. There is no commit check for this, however.

On EX4650 switches, the extension module ports support auto-channelization.

The interface will not get created automatically on inserting 1-Gigabit Ethernet or 25-Gigabit Ethernet transceivers. You must use the CLI to configure the port speed to 1-Gigabit Ethernet or 25-Gigabit Ethernet mode manually.​

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.

You can revert to the default 25-gigabit mode by using set chassis fpc <fpc-slot> pic-slot 2 port 0 speed 25g or delete chassis fpc <fpc-slot> pic-slot 2 port 0 speed <1g/10g> command.

Note:
  • When the two 100 GbE QSFP28 ports of PIC 1 of EX4400 switches are configured to operate as network ports, they support channelization.

  • You can channelize the 100GbE/40GbE ports to 4x25G and 4x10G using CLI configuration for both PIC 1 and PIC 2. See Configure Port Speed at Chassis Level and Interface Level to configure channelization.

  • You can configure one port at 100 Gbps and the other at 40 Gbps at the same time, if needed.

  • By default, each of the two QSFP28 ports in PIC1 of EX4400 (except EX4400-24X) is configured as two logical 50-Gbps VCP interfaces.

Use the request virtual-chassis mode network-port command to convert 1x100 GbE VCPs to network mode and reboot the system. Use the request virtual-chassis mode network-port disable command to disable network-port mode and reboot the system.

Port Speed on EX4100 Switches

SUMMARY Describes the supported port speeds, channelization, and autonegotiation of the EX4100 650 switches.

The EX4100 family of switches contains the following:

  • Switches: EX4100-48P, EX4100-48T, EX4100-24P, and EX4100-24T.
  • Fixed switches: EX4100-F-48P, EX4100-F-48T, EX4100-F-24P, EX4100-F-24T, EX4100-F-12P, and EX4100-F-12T.
  • Multigigabit switch models: EX4100-24MP and EX4100-48MP

In the switches, you can replace the power modules and fans, where in the fixed switches you cannot replace.

The maximum MTU size supported on EX4100 switches is 9216 bytes. Packets above MTU+8 bytes are marked as oversized frames and those 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:

  • In the EX4100 switches family, all four dedicated ports on PIC 1 are VCPs by default. You can convert the VCPs to network ports. The ports work either as VCPs or network ports, where mixed mode is not supported. On conversion of VC ports to network ports, all the ports dynamically detect the port speed.
  • 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.
  • In the EX4100 switches family, we support 1G speed on PIC1 in network mode only and not as a virtual chassis port.
