Interface Capabilities
This section describes interface capabilities like speed and Forward Error Correction (FEC). For additional information, see the EOS User's Guide. These capabilities are displayed with the following command:
show interfaces <INTF> hardware default
The speed/auto-negotiation depends on the MAC/P capabilities, the front panel connector, and the type of transceiver inserted. The default capabilities of the Arista AWE-7230R-4TX-4S Enterprise WAN router are as follows:
| Ports | Speed | Auto-negotiation |
|---|---|---|
| RJ45 (Et1/1-Et1/4) | 1G/2.5G/5G/10G full duplex | 1G/2.5G/5G/10G full duplex |
| SFP (Et1/5-Et1/8) | 1G/10G | 1G/10G full duplex
1G full duplex |
When a transceiver is inserted, EOS recognizes the transceiver type. To see which types of transceivers are supported, refer to the Supported Transceivers. EOS decides the capable speed/auto-negotiation that the hardware and the modules satisfy. To view the show commands and example outputs, refer to the Show Commands for Speed and Auto-negotiation Capabilities.
When the interface does not have a speed configuration, EOS applies the default speed. On an RJ45 port, the default configuration is auto-negotiation enabled with 10G. On an SFP port, the default configuration is auto-negotiation disabled with 10G.
Speed Configuration
This section describes the configuration of interface speed and auto-negotiation.
Interface speed and auto-negotiation are configured using the speed speed-lane-token command, as shown in the following examples:
To configure 10G speed with auto-negotiation disabled:
switch(config-if-Et1/1)# speed 10g
To configure 1G speed with auto-negotiation disabled:
switch(config-if-Et1/1)# speed 1g
To configure 10G speed with auto-negotiation enabled:
switch(config-if-Et1/1)# speed auto 10gfull
To configure 5G speed with auto-negotiation enabled:
switch(config-if-Et1/1)# speed auto 5gfull
To configure 2.5G speed with auto-negotiation enabled:
switch(config-if-Et1/1)# speed auto 2.5gfull
To configure 1G speed with auto-negotiation enabled:
switch(config-if-Et1/1)# speed auto 1gfull
To remove speed configuration:
switch(config-if-Et1/1)# no speed
Note: If the selected speed and auto-negotiation combination is unsupported (either based on the inserted transceiver or due to the interface capabilities), the interface is put into an error-disabled state with “speed-misconfigured” as the cause.
Use the following show command to check whether interfaces are connected, not connected, or error-disabled:
switch(config)# show interfaces status

For details about the different transceivers, modules, and cables, visit https://www.arista.com/en/products/transceivers-cables.
Transceiver Configuration Command Support
The first eight ports (ports 1-8) are subject to minor differences in transceiver configuration.
The shut and no shut configuration commands may not use the SFP transceiver’s TX Disable control register software. Instead, the TX Disable hardware low-speed pin signal will always be used. This does not result in operational or behavioral differences for Arista Networks transceivers.
The configuration commands transceiver frequency and transceiver channel are not supported on the first eight ports (ports 1-8).
Front Panel Port LEDs
When using the locator-led interface CLI command, the first eight port LEDs (ports 1-8) may flash at a different rate than the last eight port LEDs (ports 9-16).
Caveats
Auto-negotiation parallel detection on ports 1-8.
Parallel detection is used on Arista AWE 7250R-16S Enterprise WAN router ports 1-8, where the port can auto-negotiate. This happens when the link partner might not support auto-negotiation or the auto-negotiation is disabled on the router. In this condition, the port capable of auto-negotiation can determine if it should use auto-negotiation and can match the speed with the other router.
Parallel detection is enabled by default and cannot be disabled. Links can come up with a mismatch in the auto-negotiation configuration. If auto-negotiation is enabled on Arista AWE-7250R-16S Enterprise WAN router ports 1-8 but not on the link partner and links can be established, auto-negotiation status is successful.

Configuring the Router
Arista routers ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the router without user intervention by downloading a startup configuration file or a boot script from a location specified by a DHCP server.
To manually configure an Arista router, bypass ZTP. The initial configuration provides one username (admin) that is accessible only through the console port because it does not have a password.
When bypassing ZTP, access the router by logging in as admin, with no password, through the console port. Then, you can configure a password for the admin and other password-protected usernames.
The manual configuration procedure described below cancels ZTP mode, logs into the router, assigns a password to the admin, assigns an IP address to the management port, and defines a default route to a network gateway.
As the router boots without a startup-config file, it displays the following through the console:
The device is in Zero Touch Provisioning mode and is attempting to
download the startup-config from a remote system. The device will not
be fully functional until either a valid startup-config is downloaded
from a remote system or Zero Touch Provisioning is cancelled. To cancel
Zero Touch Provisioning, login as admin and type 'zerotouch cancel'
at the CLI.
