===== General Information =====
  * serial port is 9600 baud
  * to turn something off, put a ''no'' in front of the configuration
  * to see current configuration ''show configuration''
  * you can cut/past multiple commands/settings as once
  * see current virtual lans: ''show vlan''
  * fastethernet abbreviation is ''fa''
  * change hostname: ''hostname <HOSTNAME>''
  * ''ssh''ing in: ''ssh  -c 3des-cbc -oKexAlgorithms=+diffie-hellman-group1-sha1 <USERNAME>@<IP-ADDESS>''
  * set the channel only with physical Radio0 and not the "virtual" radios. All the SSIDs will always be on the same channel
  * vlans appear to be intended to be used only with Cisco switchports and perhaps when they are in trunk mode
    * it appears [[https://sites.google.com/site/chaseerry/cisco-routing/dhcp-relay-agent---one-dhcp-server-for-many-vlans|you can get around this]] by having the access point forward DHCPDISCOVER broadcast packets directly to our DHCP server using the ''ip helper-address'' command. 
<code>router#conf t
router(config)#int fa0.2
router(config-subif)#ip helper-address address_of_server
router(config-subif)#end 
</code>
  * 8266 with Arduino Wi-Fi library seem happiest with ''encryption mode ciphers aes-ccm''

note: see comment about vlans and switchports above. That configuration for the fastethernet **may** be required
