Disney Toon Studios

I was fortunate enough to get invited for a lunch trip to Disney Toon Studios in Glendale, Ca. This was a chance to visit friends and see their new building.  It's really a neat campus.  I was told that the large atrium area was designed by Allied Works Architecture which is the same firm that designed the new building for Pixar Animation studios. I got to visit Pixar while up in San Francisco for WWDC 2010 and really enjoyed seeing their facility as well. Both sites are great facilities with wonderful open spaces.

When you first walk in, you see a large open area. 

The nice thing about a space like this is it makes folks cross paths.  I find that meetings in the hallway tend to be my most productive ones. When meeting in the hallway, you are talking because you have something you really need to talk about, and the meeting ends on time because everyone is standing.


The open area has a Pool Table, Video Games, and Cereal Bar.  These things do a great job of drawing folks into the common area.

Conference rooms are adjacent to the common area as well.

The wood is beautiful.

There is a nice outdoor garden area and lunch tables as well.

Tuesdays With TED

Every Tuesday morning, the faculty and staff at SCVi Charter school, gather together to watch a TED Talk.  After the talk we discuss what we learned and how it is relevant to our lives and work. This blog posting is meant to be a running tally of the talks we have reviewed. It will consistently be edited as we watch more.

SCVi Summer 2011 Wireless Project

Overview Of The Project

Wireless devices are now an important part of the learning environment. Students make use of laptop computers, iPods, iPads, and  Netbooks in their learning at our school. In summer 2011, we decided to increase our wireless usage by adding 30 school owned iPads and about 70 new Netbooks.  We also greatly increased the number of school-issued teacher and staff laptop computers and increased our school enrollment from around 500 to over 750.  This warranted a substantial improvement in our wireless network.

What We Started With

For the first three years of Operation, SCVi had a total of 4 wireless access points. These were located throughout the building, but the largest concentration was upstairs in the south wing. This document shows these as "Old AP" and are represented by the blue circles. It also shows some places we were considering adding new AP's for a more optimal coverage and these are marked as Meraki AP's because that is the first vendor we looked at. 

All access points were Cisco Aironet 1200's which we felt could service about 20 users each before we started to see significant performance issues.  With this many access points, we could service about 80 simultaneous users, which meant the school wireless network would come to a crawl by mid morning.

Wireless Research

We started investigating vendors for our wireless upgrade. We knew we wanted to go to Wireless N technology which would give our access points greater speed, greater range, and more concurrent users. We started looking at different vendors. The following table shows some of the vendors we talked with.

Vendor	Option	Hardware Included	Recurring Cost ( per year)	Notable Features
Meraki / IMT	New Access Points Only	Meraki MR16 Cloud Managed AP	Mandatory Fee For Cloud Controller Access. Pay per AP.	Cloud controller ONLY. Cloud controller has an annual fee per access point Great features on the cloud controller and overall very polished product.  Would be nice for multiple sites.
Meraki / IMT	New Access Points + New Router	Meraki MR16 Cloud Managed 1x Meraki MX70 Cloud Managed Router	Mandatory Fee For Cloud Controller Access. Pay per AP. + License Fee for Router.	Router has two inputs and automatic failover. Router will not act as the controller, you still need to pay for a cloud controller.
Aerohive / Altaware	New Access Points Only	Aerohive AP-120	Mandatory Fee For Cloud Controller Access. Pay per AP.	Cloud controler. Cloud controller has an annual fee per access point, but fee is less than Meraki.  You can buy a controller for in-house control, but is very expensive.
Blue Socket / Intuitive Networks	New Access Points Only	Bluesocket vWLAN Server Blue Socket 1800 Access Points	Optional Support Only.	Controller is in-house. No cloud needed.  Was the only vendor that provided us with a Demo access point. This was very nice.  We were able to get a single access point up and running using their cloud controller without too much trouble.
Blue Socket /CDW	New Access Points Only	Blue Socket 1800 Access Points	Optional Support
Aruba / CDW	New Access Points Only	Aruba AP-15 Acces Points	Optional Support	This is the Aruba Instant solution. It maxes out with 16 AP's. After that, you have to buy a controller. Very nice and simple config. Check out the video from Aruba.
Aruba / CDW	New Access Points + Aruba Controller	Aruba AP-15 Acces Points Aruba Controller  $100 per AP License Fee For Controller	Optional Support	Controller required for more than 16 ap's. Could buy controller later. I like their tutorial videos If using the controller, you can no longer use Aruba Instant so you have to pay $100 per AP licensing fee.
DLink / 110 Technology	New Access Points Only	DLink DAP2553	-	Cheapest possible solution and still a huge upgrade from what we have now.
DLink / 110 Technology	New Access Points Only	DLink DAP2590	-	Plenum rated version of the DAP2553. Put above ceiling.
DLink / 110 Technology	New Access Points Only	Dlink DAP 2555	Mandatory Fee For Cloud Controller Access. Pay per AP.	This is DLink's Cloud solution Cloud based solution. Fee is $100 per access point. If we want cloud controlled, this is the cheapest.
DLink / Computer1	New Access Points + Controller	DLink DWL-8600AP DLink DWS-4026 Controller	Optional Warranty	Most robust hardware solution. Scales to 64 access points. Includes a 24 port switch - Nice. Best overall value of Hardware for $$

We decided to go with Aruba for these reasons:

• The solution scales nicely. You can start with Aruba Instant, then go to Aruba with a controller or cloud based as you get larger.
• Good tutorials and videos on web site.
• Software looks polished and is easy to use. 
• We got a really good quote. 

Implementing The Access Points

Our old access points had three separate SSID's.  Each had different routing to different VLAN's.  All three were open, but only one broadcast the SSID.  Here is an overview of the config from one of our Cisco access points.

Each of the access points is routed to a separate network with different filtering in Open DNS. This allows us to filter the content for teachers separately than the content from the student population.  Since the SSID's of the old access points were not very descriptive, we decided to change them.

Old SSIDs	Security	New SSIDs	New Security	VLAN Purpose	IP Domain	Internet Supplier
Stars	Open	SCVi-Learner	Open	Student usage	172.168.128.xx, 172.168.129.xx	Fireline Broadband 10Mbit
Ambassadors	Open - Hidden SSID	SCVi-Facilitator	WPA2 - Password Protected	Teacher, Admin, and Staff usage	172.168.12.xx	Telepacific 10Mbit
guru	Open - Hidden SSID	SCVi-Admin	WPA2- Password Protected	Network Administration by IT Staff	192.168.250.xx	Telepacific 10Mbit

When the Aruba access points arrived, we started setting them up.  Configuration is pretty easy. You plug in the first access point and connect to it with a computer. You then navigate a web browser to http://instant.arubnetworks.com and use a web page to configure the device. Here is how the network configuration for the above SSIDs looked in the Aruba software.

The Learning Really Begins

As soon as we plugged in the access point, it became evident that our old Cisco Catalyst 3550 was not going to be able to power the new Aruba AP's. The AP's would cycle on and off but never started up. For the first AP, we simply constructed a external power supply to get started and worked with it plugged into the 3550. This worked for one AP, but this was not going to work for the rest of the network.

In order to power the new AP's properly, we purchased a DLink DGS-3100-40 managed POE switch.  This powered the AP's nicely, but after a few days of trying to get it to work, we realized the configuration was going to take some learning.  We needed to get the VLAN's used by the AP's to properly propagate through the new switch.  Otherwise, we could only get them working on the administration network.  It was time to call in some help!

We were able to get some expertise from Earl Rolley who helped design our original network.  He helped work out a lot of our configuration problems with our Cisco equipment. However, after plenty if tinkering, we still were not able to get the DLink switch up and running. So, we are running off the old switch and using POE Power injectors.  Still, we have learned a lot. Some highlights of the config are as follows.

• We replicated all of the VLAN's from the cisco hardware on the DLink switch and configured it to tag the ports for these VLAN's.
• Any switch on the Cisco hardware that fed the Dlink Switch or an Access Point must be set to mode "trunk".  (See cisco commands below.)
• The drop to POE#3 Kindergarten had significant configuration problems that I simply didn't understand. Earl figured them out and set things correctly. 
• What Cisco calls "Trunking" and DLink calls "Trunking" are totally different things. When Cisco configures a port to "Trunk" that means it's meant to feed another switch. However, in DLink, it is port aggregation. 
• We enabled Spanning Trees on the DLink switch, but still not sure if that was the right thing to do. 
• Since we use VLAN 250 as our admin VLAN; To talk to the Dlink switch as an admin plugged into a port, configure all the VLANs to be off except 250.

Understanding Switch Ports and VLANs
Virtual LANs allow different ports on a switch to be configured to talk to different networks. Our old access points were plugged into ports 1-4 on POE switch #2.  We actually were set up to talk to them on 8 total ports. This document shows how things are configured. For the new DLink switch, we plugged it into the Gigabit Ethernet port on SW1 and configured the port to trunk.

Learned Some Cisco Commands

There were several cisco commands I learned while configuring the switches. These commands can be performed by logging into the switch using telnet or ssh.

Command	Type	What it does
show vlan	Read	Shows the VLAN's configured on the device
show run	Read	Shows the entire switch config as currently running
show ip dhcp server	Read
show ip dhcp server statistics	Read
show interfaces	Read	show the interfaces on the device
show version	Read	shows software version, but more importantly, shows Uptime
show power inline	Read	shows POE status on POE switches/td>
show interface status	Read	show status of each interface.
show startup-config	Read
show cdp neighbor	Read	Show who is connected to a port. (Handy!) Must be in switchport mode.
show run interface fastethernet 0/1	Read
show run interface fa 0/46	Read	Notice that you can abbreviate the word fastethernet
show run interface gig 0/1	Read
config	-	Puts you into configuration mode so you can change settings.
interface fastethernet 0/6	-
switchport access vlan 250	Write	Adds the port to VLAN 250
no switchport access vlan 128	Write	Removes VLAN 128 from a port
switchport mode access	Write	Tells a port to auto-detect for Trunk or VLAN mode.
switchport mode trunk	Write	Change the switchport to TRUNK mode
switchport trunk encapsulation dot1q	Write	Change port mode to 802.1q (Allows TRUNK mode)
do show run interface fastEthernet 0/48	Read	When in config mode, you can use "do" to run the regular Read commands
write	Write	Set's the configuration to be saved for next time the switch reboots

Using the above comamnds, we were able to learn some really useful things. For instance to see what VLANs are available on a particular port, you can use the "show vlan" command.

SCVI-POE-SW2#show vlan
VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    
2    gateway_network                  active    
4    VLAN0004                         active    
12   VLAN0012                         active    
20   network_printers                 active    
30   teacher_network                  active    
40   student_network                  active    
50   VoIP_phone_network               active    Fa0/9, Fa0/10, Fa0/11, Fa0/12, Fa0/13, Fa0/14, Fa0/15, Fa0/16
                                                Fa0/17, Fa0/18, Fa0/19, Fa0/20, Fa0/21, Fa0/22, Fa0/23, Fa0/24
60   office_administration_network    active    
128  VLAN0128                         active    
250  network_administration_network   active    Fa0/5, Fa0/6, Fa0/7, Fa0/8, Fa0/9, Fa0/10, Fa0/11, Fa0/12, Fa0/13, Fa0/14
                                                Fa0/15, Fa0/16, Fa0/17, Fa0/18, Fa0/19, Fa0/20, Fa0/21, Fa0/22 Fa0/23, Fa0/24

This is the typical config for a "Trunk" port on the cisco switch. i.e. Ports that power either an Access Point, or a Phone. (The phones are a Trunk device)

description NetworkAdministration
switchport access vlan 250
switchport trunk encapsulation dot1q
switchport trunk native vlan 250
switchport mode trunk
switchport voice vlan 50
mls qos trust dscp
priority-queue out
spanning-tree portfast

Here is a config from the "Student" ports on the POE switch that feeds high school.

switchport access vlan 128
 switchport mode access
 switchport voice vlan 50
 power inline never
 spanning-tree portfast

Network Overview - For Technical Parents

Since our school relies heavily on parent volunteers, We have documented our entire network here.  This is to help future parents understand how we are configured.

iPad Resources

Our school has decided to buy iPads for student use. This was a big decision in many ways because we want to make sure they are actually used for educational purposes instead of as a easy way to sneak an update to your facebook status. (although we block facebook right now).  Here are some links that were being passed around as we did our research.

• Lessons From an iPad Rollout
• This is a decent post talking about many of the concerns involved in rolling out iPads.  Issues such as wireless coverage and training of staff and parents is discussed.
• The Proper Care and Feeding of iPads
• This is a fun little video from a school that issues ipads to its students. For our first pass, we'll probably go with an iPad cart. Though, in the long run we'll probably have some issued to students as well.

• Do You Know Where Your School iPads Are?
• This article talks about keeping track of your mobile devices. In the end, it just becomes a sell job for some software called Absolute Software's Computrace product. Though, there's some good advice in there about keeping track of your hardware.
