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.

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.

The 4xSFP+ ports in EX4100-F can be network ports or VCPs, but not both at the same time. See EX4100 and EX4100-F System Overview for EX4100 and EX4100-F PIC terminology.
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.
