Arista 7148S switches

Core switches (Arista 7148S)

The 7100 series from Arista switches are different from all others. A few hints:

• The serial port setting is 9600 8N1 with NO flow control
• The local user is admin
• It is not possible to configure the management part of this switch over the 10Gb fiber optics, you need to use the special RJ45 ports on the switch for this

Basic Configuration

enable
configure terminal
interface management 1
ip address <ip> <netmask>
ip route 0.0.0.0 0.0.0.0 <gateway>
hostname <name of switch>
username admin secret 0 <password>
end
copy running-config startup-config

Update OS

enable
copy http://webserver/EOS-4.2.2.swi flash:EOS-4.2.2.swi
