==Fix PoE port resetting==

The Cisco switch power cycles PoE ports when the link goes down or takes too long to come up, causing the Aruba APs to keep powercycling without coming up.

To fix this:

  Switch>enable
  Switch#configure terminal
  Switch(config)#interface range FastEthernet 0/1-24
  Switch(config-if-range)#power inline delay shutdown 20 initial 300

This saves it to running-config, but because of a bug, the running-config does not actually show it when you run "show running-config". Instead, use "show running-config all" (which also shows the defaults) to display the values, even though they are not defaults.

<b>NOTE: to make this config persistent, you need to run "copy running-config startup-config all". The 'all' circumvents the bug above. After this, "show startup-config" also shows the necessary PoE settings and the switch reboots correctly.</b>

=Unifi Edgerouter X=

*dhcp servers:
**let erop dat je de pool start/end moet invullen, anders is de pool size 0 en krijg je geen leases
**mgmt 10.138.64.0/24
**villanova 10.138.65.0/24
**hsn 10.138.66.0/24
*in de config tree: service -> gui -> listen-address "10.138.64.1" zodat ie alleen bereikbaar is via management vlan

==Ports==

*eth0 wan --> kpnrouter
**dhcp client
*eth1 lan --> cisco poe port 1 trunkport
**vlan 1 (untagged)
**vlan 64 (dhcp-server)
**vlan 1336 (dhcp-server)
**vlan 1337 (dhcp-server)
*eth2
**vlan 1 (untagged)
**vlan 64 (dhcp-server)
**vlan 1336 (dhcp-server)
**vlan 1337 (dhcp-server)
*eth3
**vlan 1 (untagged)
**vlan 64 (dhcp-server)
**vlan 1336 (dhcp-server)
**vlan 1337 (dhcp-server)
*eth4
**vlan 1 (untagged)
**vlan 64 (dhcp-server)
**vlan 1336 (dhcp-server)
**vlan 1337 (dhcp-server)

== Firewall ==
Reject traffic from guest VLANs (villanova & HSN) to management VLAN:

* Firewall/NAT -> Firewall/NAT Groups -> create "management" group, then Actions -> Config and set network "10.138.64.0/24" and save
* Firewall Policies -> Add ruleset "GUEST_NET_LOCAL" :
** Description "Guest to router"
** Default action DROP
** add rule 1 "allow DNS" action Accept protocol TCP+UDP destination port 53
** add rule 2 "allow DHCP" action Accept protocol UDP destination port 67
** go to Interfaces and add switch0.1336 direction local, and switch0.1337 direction local
* Firewall Policies -> Add ruleset "GUEST_NET_IN"
** Description "From villanova/HSN nets"
** Default action ACCEPT
** add rule 1 "drop guestnet to mgmt" action Drop protocol All protocols destination network group Management subnet
** go to Interfaces and add switch0.1336 direction In, and switch0.1337 direction In

Now, hosts on villanova & HSN nets can use DHCP and DNS, but nothing else on the router; also, they can't access the management subnet at all.

=Aruba Accesspoints=

==Setup==

*hang aan HSN-poortje (5/6) en wacht tot ie een lease krijgt in het HSN-subnet
*log in op de controller, klik op AP -> Configuration -> Edit -> Uplink -> management vlan is 64
*maintenance -> reboot -> AP -> reboot selected
*reboot --> na de reboot, trek hem uit poortje 5/6 en zet hem in poortje 2/3/4 (de AP-poortjes)
*hij moet nu een lease krijgen in het management-subnet
*hij vindt dan automatisch zijn controller, en biedt dezelfde netwerken aan

==Individuele settings==
Op de controller zijn alle APs online. Maak een nieuw wired network genaamd "passthrough" met:

*Primary usage employee
*PoE enabled
*Admin status Up
*Mode Access
*Client IP Network Assigned
*Access VLAN 1336 (villanova)
*VLAN Assignment Rule "If AP-Name equals AP233 assign VLAN 1337" (AP233 is de accesspoint waar de netwerkkabel naar ons atelier doorheen lust)

Stel "passthrough" in op alle wired poortjes behalve 0/0 (die blijft op default_wired_port_profile).
