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.

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.

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

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
