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 (uni t 0) and assigns it to f ami l y ether net-

swi t chi ng (except on EX8200 switches and Virtual Chassis)

Specifies Rapid Spanning Tree Protocol (RSTP) and Link Layer Discovery Protocol

(LLDP)

This topic describes:

Configuring VLAN Options and Interface Mode

Configuring the Link Settings

Configuring the IP Options

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 def aul t . You

can optionally configure another VLAN and use that instead of defaul t . You can also

configure a port to accept untagged packets from the user-configured VLAN. For details on

this concept (native VLAN), see Understanding Bridging and VLANs on EX Series

Switches

If you are connecting either a desktop phone, wireless access point or a security camera to a

Power over Ethernet (PoE) port, you can configure some parameters for the PoE interface.

PoE interfaces are enabled by default. For detailed information about PoE settings, see

Configuring PoE (CLI Procedure).

If you are connecting a device to other switches and to routers on the LAN, you need to

assign the interface to a logical port and configure the logical port as a trunk port. See Port

Role Configuration with the J-Web Interface (with CLI References) for more information

about port configuration.

If you are connecting to a server that contains virtual machines and a VEPA for packet

aggregation from those virtual machines, configure the port as a tagged-access port. See

Understanding Bridging and VLANs on EX Series Switches for more information about

tagged access.

To configure a 1-Gigabit, 10-Gigabit, or 40-Gigabit Ethernet interface for trunk port mode:

EX Series switches include a factory default configuration that enables interfaces with the

link settings provided in Table 1.
