Configuring Gigabit Ethernet Interfaces (CLI Procedure)
NOTE: This task uses Junos OS for EX Series switches with support for the
Enhanced Layer 2 Software (ELS) configuration style. If your switch runs
software that does not support ELS, see Configuring Gigabit Ethernet Interfaces
(CLI Procedure). For ELS details, see Getting Started with Enhanced Layer 2
Software.
An Ethernet interface must be configured for optimal performance in a high-traffic
network. EX Series switches include a factory default configuration that:
•
Enables all the network interfaces on the switch
•
Sets a default interface mode (access)
•
Sets default link settings
•
Specifies a logical unit (unit 0) and assigns it to family ethernet-switching (except on
EX8200 switches and Virtual Chassis)
•
Specifies Rapid Spanning Tree Protocol (RSTP) and Link Layer Discovery Protocol
(LLDP)

Configuring VLAN Options and Interface Mode
By default, when you boot a switch and use the factory default configuration, or when
you boot the switch and do not explicitly configure a port mode, all interfaces on the
switch are in access mode and accept only untagged packets from the VLAN named
default. You can optionally configure another VLAN and use that instead of default. You
