# Switch configuration
#
# Use swconfig list to see available switches. Use swconfig dev <switch-name> show
# to show actual switch configuration. Use swconfig dev <switch-name> help to show 
# available features. More information:
# https://wiki.openwrt.org/doc/techref/swconfig
#
# This example assumes:
#
# CPU   5      - swconfig dev switch0 help | grep "cpu @"
# -------
# LAN   4      - vlan 1
# LAN   3      - vlan 1
# LAN   2      - vlan 1
# LAN   1      - vlan 1
# WAN   0      - vlan 2
#
# The 't' in vlan ports make sure that a vlan tag is set and
# visibile on the virtual network device in linux. Each switch
# device (like switch0) has a virtual network interface counter-
# part in Linux (eth0 for example).
