Arista devices ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the device 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 device, 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 device by logging in as admin, with no password, through the console port. Then, you can configure a password for admin and other password-protected usernames. The manual configuration procedure described below cancels ZTP mode, logs into the device, 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 device 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. localhost login: 1. Connect the device to a power source (Cable the Device). Note: Arista fixed devices take approximately 5 to 10 minutes to boot completely. 2. Connect the console port to a computer (Connecting Serial and Management Cables). 3. Log into the device by typing admin at the login prompt. localhost login: admin 4. Cancel ZTP mode by typing zerotouch cancel Important: This step initiates the device to reboot. localhost> zerotouch cancel 5. After the device reboots, log into the device again by typing admin at the login prompt. Arista EOS localhost login: admin Last login: Fri Mar 15 13:17:13 on console 6. Enter global configuration mode. localhost>enable localhost#config
- Assign a password to the admin username using the username secret command. In this example, the assigned password is "pxq123". localhost(config)#username admin secret pxq123 localhost(config)#interface management 1/1 localhost(config-if-Ma1/1)#ip address 192.0.2.8/24 10. Save the configuration by typing write memory or copy running-config startup-config. localhost#copy running-config startup-config 11. When configuring the management port IP address, select the following command to access the device from a host using the address configured in Step 9. ssh admin@192.0.2.8 Refer to the Arista Networks User Manual for the complete device configuration information.

If the transceiver is supported, EOS decides the capable speed and auto-negotiation satisfied by both the hardware and the modules. To view the show commands and examples output, refer to Show Commands for Speed and Auto-negotiation Capabilities. When there is no speed configuration on the interface, 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: Arista(config-if-Et1/1)# speed 10g To configure 1G speed with auto-negotiation disabled: Arista(config-if-Et1/1)# speed 1g To configure 10G speed with auto-negotiation enabled: Arista(config-if-Et1/1)# speed auto 10gfull
Interface Configuration and Behavior To configure 5G speed with auto-negotiation enabled: Arista(config-if-Et1/1)# speed auto 5gfull To configure 2.5G speed with auto-negotiation enabled: Arista(config-if-Et1/1)# speed auto 2.5gfull To configure 1G speed with auto-negotiation enabled: Arista(config-if-Et1/1)# speed auto 1gfull To remove speed configuration: Arista(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: Arista(config)# show interfaces status Port Name Status Vlan Duplex Speed Type Flags Encapsulation Et1/1 connected routed full 10G 10GBASE-T Et1/2 connected routed full 10G 10GBASE-T Et1/3 connected routed full 10G 10GBASE-T Et1/4 connected routed full 10G 10GBASE-T Et1/5 connected routed full 10G 10GBASE-CR Et1/6 connected routed full 10G 10GBASE-CR Et1/7 connected routed full 10G 10GBASE-CR Et1/8 errdisabled routed full 100G 10GBASE-CR Use the following show command to display why an interface is error-disabled: Arista(config)# show interfaces ET1/8 status errdisabled Port Name Status Reason Et1/8 errdisabled speed-misconfigured When a transceiver is in an error-disabled state due to a misconfigured speed, the following syslog message is logged: bessd[4392]: %ETH-4-LINKMODEUNSUPPORTED: Unsupported link mode 100G/full for interface Ethernet1/8 Ebra: %ETH-4-ERRDISABLE: speed-misconfigured error detected on Ethernet1/8. Show Commands for Speed and Auto-negotiation Capabilities Supported speed and auto-negotiation are displayed by the following command when the transceiver is inserted: show interfaces <INTF> hardware Arista(config)#show int ET1/1 hardware Ethernet1/1 Model: ZTX-7250F-16S-F Type: 10GBASE-SR Speed/duplex: 10G/full(default) Flowcontrol: rx-(off),tx-(off) Error correction: unsupported
The onboard SFP ports support a wide range of 1G and 10G pluggable transceivers. The first eight ports (ports 1-8) support the following transceivers:
- CAB-SFP-SFP (10GBASE-CR)
- AOC-S-S-10G (10GBASE-AOC)
- SFP-10G-SRL
- SFP-10G-SR
- SFP-10G-LRL
- SFP-10G-LR
- SFP-1G-SX
- SFP-1G-LX
- SFP-1G-T The last eight ports (ports 9-16) support the following transceivers:
- CAB-SFP-SFP (10GBASE-CR)
- AOC-S-S-10G (10GBASE-AOC)
- SFP-10G-SRL
- SFP-10G-SR
- SFP-10G-LRL
- SFP-10G-LR
- SFP-10G-ER
- SFP-10G-ZR
- SFP-10G-DZ (10GBASE-DWDM)
- SFP-10G-T
- SFP-1G-SX
- SFP-1G-LX
- SFP-1G-T 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 the ports 1-8, where the ports can perform auto-negotiation. This happens when the link partner might not support auto-negotiation, or the auto-negotiation is disabled on the device. In this
Interface Configuration and Behavior condition, the port capable of auto-negotiation can determine if it should use auto-negotiation and can match the speed with the other device. Parallel detection is enabled by default and cannot be disabled. Links can come up with a mismatch in auto- negotiation configuration. If auto-negotiation is enabled on Arista ZTX-7250F-16S-F ports 1-8, but not on the link partner and links can be established, then auto-negotiation status is successful.
