We are pulling two wires to each location in all new construction.  As we
redesign our wireless deployment, we are pulling two wires to those
locations as well.

 When you have new construction, do you plan on running 2 drops so when
 phase 2 come into play you will be all set for it?

Brian,

While we are not planning to move to 802.11ac for a couple of years, we
are indeed running 2 drops per access point in preparation.

Dorms already have 2 because we are reusing the station wiring from the

RE: How many drops 802.11ac phase 2

[Peter P Morrissey]

For new construction we are doing two, but not for existing drops. The more 
interesting question I think is what kind of cabling people are using for them. 
We are going to start using Cat6a with the assumption that the lifecycle 
replacement of our cabling is 15-20 years and within that time, the AP's will 
be 10 Gig, maybe even a lot sooner.

To ALL:

  Well I guess we are the odd man out.  We are pulling one cat6a and 
will continue to so.  I just do not see the point in pulling two. First 
off the wired bandwidth is never the issue on the AP, I would bet most 
of my ap's run at 100meg, gig will be fine for a very long time.  
Second, I just do not see the AP vendors going to two ports with some 
type of bonding.  My Guess is they will eventually go one 10gig port if 
they ever get to the point where they need the bandwidth.  I guess we 
may pull two in some very select locations, I just don't see it for 
general deployment.  The other thing that would change our mind is if a 
vendor, went to and stuck with two ports on a AP, we might start pulling 
two.

Re: [WIRELESS-LAN] How many drops 802.11ac phase 2

[Hanset, Philippe C]

Is the main justification for two drops due to power/bandwidth/the-two?

With many services and most killer apps going to the cloud, I would suspect 
that the bandwidth to the WAN is so limiting,
that this excess of capacity on Wireless is a complete overkill (a vendor 
driven non-sense).

Yes, those 802.11ac Phase2 APs can generate a lot more than 1 Gbps, but that's 
is shared bandwidth (half-duplex),
and your uplink is 1 Gbps full-duplex (2 Gbps in Cisco math as we said in the 
old days).

So, you really plan to also uplink your switches with 40 Gbps, and then a core 
at many times 100 Gbps, all connected
to your ISP at a few Gbps... something doesn't add up here.

Am I alone making bad accounting here?

RE: [WIRELESS-LAN] How many drops 802.11ac phase 2

[Patrick Mauretti]

Keep in mind, the actual signal strength needed to achieve the 1Gbps rates 
that would actually require multiple cable runs is extremely high.  If you know 
of a classroom/environment where that type of data can be pulled down, by all 
means pull two cables.  But it's been my experience that most wireless traffic 
is not intranet, but internet, and as such is far more limited by your ISP 
bandwidth than it is by the AP (or its wiring) itself.

Re: [WIRELESS-LAN] How many drops 802.11ac phase 2

[James Helzerman]

Specifically speaking about WiFi locations, we have been running two CAT5e
since 2004.  The reasoning then was the second cable to attach to the
console port in case of an autonomous AP losing its config.  Today we are
still running two CAT5e since the cost of pulling a second wire is very
minimal compared to labor to go back later.  The intent now is for future
proofing not just for WiFi but for other devices such as cameras that may
be placed nearby.  In the future we may not need dual uplinks, but an
additional access point nearby.  How many classrooms and auditoriums have
had WiFi in the past but now need additional access points for density?

There are currently manufactures that do have dual uplinks.  Aruba is one
of them with their new 802.11ac wave one AP.  In my opinion, I see vendors
going both way, dual uplinks and 10Gbps at some point.  I believe vendors
will try to find ways to differentiate themselves from the others.  One way
to do this is to offer compatibility with existing wiring or a migration
path such as dual links with one or both 10Gb capable.  Not every location
will need 10Gb either and as others have mentioned at this point we are
bottleneck engineering.  We are starting to look at CAT6a to see if it is
time to switch but for now we are still pulling CAT5e even in new
construction.

So, I've been running 2 WiSM-2 HA clusters running 7.6.100.0 in non-VSS for 
about a month.  In the last week one of the clusters has had every AP (1142's 
and 3502's) drop the CAPWAP tunnel to the controller.  The controller has not 
failed over, the 6500 chassis either reside in have not failed, OSPF or BGP 
flapped, the APs haven't even rebooted - just dropped the CAPWAP tunnel.

The only thing I've seen in logs is this:

AP 'ap-NAME_HERE, MAC: 00:25:45:XX:XX:XX disassociated previously due to AP 
Reset. Uptime: 0 days, 00 h 01 m 11 s . Reason: watchdog timer reset.

I do have a TAC case open, but wanted to reach out and see if anyone else has 
seen similar behavior.

RE: [WIRELESS-LAN] Cisco 7.6.100.0 question......

[Danny Eaton]

Thanks Lee - The APs are using DHCP, and the DHCP seems to be fine (both
servers up/passing IPs).  Only 1 HA cluster (700+ APs) has had this problem,
the other HA cluster has not (over 600 APs).  The APs are not losing IP, nor
rebooting - just dropping CAPWAP.

So, I've been running 2 WiSM-2 HA clusters running 7.6.100.0 in non-VSS for
about a month.  In the last week one of the clusters has had every AP
(1142's and 3502's) drop the CAPWAP tunnel to the controller.  The
controller has not failed over, the 6500 chassis either reside in have not
failed, OSPF or BGP flapped, the APs haven't even rebooted - just dropped

Re: [WIRELESS-LAN] How many drops 802.11ac phase 2

[Jeffrey Sessler]

Pulling two during construction is a lot less expensive then going back at a later date to add more. I'd consider the additional cable more for expanding the number of AP's at a later date rather than trying to satisfy any theoretical max bandwidth in 11ac phase 2. After all, if you're designing for real-time applications in 5GHz e.g. VoIP, the number of AP's will be high enough that your clients-per-ap will be very low, andthus unlikely to ever operate at the theoretical max.

My residence halls have had "gigabit to the pillow" since 2003, and even at it's peak usage,the 1Gbstrunks from each80-100 bed hallnever got much above 20-15% utilization. I have serious doubts that my WiFi in any of the same halls will ever be higher.

 I just do not see the point in pulling two. First off the wired bandwidth is 
 never the issue on the AP, I would bet most of my ap's run at 100meg, gig 
 will be fine for a very long time.

 That is our bet.

 Second, I just do not see the AP vendors going to two ports with some type

 Well some vendors at least do support multiple wired ports already.  How they 
 divide up traffic between those ports varies.

RE: [WIRELESS-LAN] How many drops 802.11ac phase 2

[Peter P Morrissey]

Hi Philippe,

This is a great discussion and I'm glad to see we're not the only ones 
struggling with these issues. I'll add my 2 cents on a number of issues brought 
up in the thread, and yes I think some of your accounting is a bit off.

First off I don't think it helps to have this discussion without recognizing 
that the life cycle of cabling is generally 15-20 years, sometimes more. There 
are exceptions, but this is the general practice for a number of reasons. I 
don't know anybody who is concerned about 11ac phase 1 bandwidth, and even the 
phase 2 that you mention, there is a lot of skepticism about how much it will 
really utilize. It is important to recognize however, that full duplex does not 
help you if the traffic is asymmetric, weighted towards the consumer, which is 
what we see. You still only get one gigabit at a time in each direction. I 
think it is also important to consider that the network is 100% utilized 
whenever there is data transmitted. The game we play is engineering so that 
that happens infrequently enough so as not to cause excessive queuing, or 
worse, excessive packet loss that would be noticed by the end user. We often 
see five minute averages of utilization that round out a lot of this, and it 
isn't a problem until there are periods of time when it happens enough to cause 
delay, packet loss, and retransmissions that impact the end users experience. 
Whether this is going to happen with 11ac phase 2 or not seems unlikely to me, 
but I think it is a legitimate debate. I would be concerned, except we see 
utilization at five minute averages that is often not much more than 25% for a 
whole residence of AP's. But does anyone really think it is wise to assume that 
an AP won't exceed a gig per AP during the lifespan of the cable? If you look 
at the rate of growth of bandwidth on the Internet over the past and the 
projections for the future, assuming they are even close, and the rate of 
change and innovation, I think this would be a very risky assumption to make.

It certainly does seem like more is moving to the cloud. I would say we haven't 
found it to be cost effective, or secure enough and we still offer a lot of 
services on our local campus network which are faster, closer and more reliable 
than the internet. We also have Akamai appliances that cache Internet content 
and improve the response time for our users while helping cut down on bandwidth 
utilization. We have all kinds of programs that move large amounts of data 
including 3d drawings and video. If we did move more to the cloud, we would 
likely have to upgrade our Internet connection which is already at 6 Gigabits, 
and we will continue to upgrade over the coming years whether we move to the 
cloud or not. But I suppose if you keep your bandwidth low enough upstream, 
then you don't have to worry about these things at all.

Right now we do indeed have 10 Gig in the core, and are putting in 10 Gig to a 
lot of our buildings. We are also putting in some 40 Gig to the core, although 
that at the moment is admittedly more driven by researchers. In theory we are 
still oversubscribed by quite a bit in regards to how much every user or AP can 
theoretically use, and that model works very well as long as the nature of user 
traffic is as bursty as it has tended to be thus far. But bottlenecks can occur 
in practice, and we watch for them so they don't impact performance.

I have to say that I don't think it is necessarily a bad idea to run one cable 
(assuming it is cat6a) instead of two, even though we run two. And we may 
re-evaluate this approach ourselves as we see things develop. If you do run one 
Cat6a you just have to bank on the AP vendors switching to 10 Gig connectivity 
before bandwidth becomes an issue for you.  I don't think that amounts to a big 
risk, but we've decided for now that given the incremental cost to pull two, we 
are going to do it for the insurance. One of the challenges with running two is 
that we will need space in closets to support the extra cable which could also 
be a bit of a challenge.

Subject: Re: [WIRELESS-LAN] How many drops 802.11ac phase 2

Is the main justification for two drops due to power/bandwidth/the-two?

With many services and most killer apps going to the cloud, I would suspect 
that the bandwidth to the WAN is so limiting,
that this excess of capacity on Wireless is a complete overkill (a vendor 
driven non-sense).

Yes, those 802.11ac Phase2 APs can generate a lot more than 1 Gbps, but that's 
is shared bandwidth (half-duplex),
and your uplink is 1 Gbps full-duplex (2 Gbps in Cisco math as we said in the 
old days).

So, you really plan to also uplink your switches with 40 Gbps, and then a core 
at many times 100 Gbps,

Strange 802.1x behavior with single signon

[John Kaftan]

We have a number of laptops that are mobile labs (Tanks) and in the library
for students to check out.

We push the 802.1x settings via AD and it works very well.  The problem we
have run into is that when we have login set to 'user or computer' and
check single sign-on it comes up and logs into the network using the
computer name just fine.  But then when the user logs in it immediately
authenticates 802.1x as the user and then proceeds to churn until
ultimately failing with No logon servers found.

The strangest thing about this is that packet captures reveal that while
the machine is churning it is sending out ARPs for its gateway.  The
gateway replies but the client ignores it.  It does this 30-40 times before
giving up.

If the user has logged onto the machine before they will get on with cached
credentials and they will be fine, other than being grumpy over how long it
takes to get on.  If they have never logged on before they will get the
dreaded No logon servers found

Doing a 'ARP -a' at the command line reveals the gateway address is listed
and the machine is able to browse just fine.

I don't think this is a wireless\policy issue as I set up the client to get
our IT_Admins profile no matter what and also after the client finally
stops asking for the gateway's mac address everything is fine.

Our work around is to just set it to Computer authentication only.  This is
a bummer because we lose visibility as well as the ability to apply user
based profiles.

Re: How many drops 802.11ac phase 2

[Green, William C]

We pull one 6a also.  That makes enough of us to drink together comfortably at 
the next Educause party.

Most of our APs are one 5e.  As well discussed, I also expect GE to be 
sufficient for a number of years, but I never bet against more bandwidth (we 
consume 3 orders of magnitude more WAN bandwidth than from when I started my 
career).  Power use to be my concern driving the consideration for two cables 
(and I think we have that in several buildings), but not with the new POE 
standards.

Given the amount of 5e out there (thinking beyond WiFi), the magic of market 
forces will likely provide additional options for more bandwidth across 5e 
(just look at the  options for Cat 3 as ugly as they might be).  

10G capable ports on APs will be an after-thought in 4-5 years.  Vendors would 
have to look hard to find chips that don't do 100/1000/1 (etched glass, 
moore's law, all that).

If I had the funds, I would consider two, but I don't have funds or 
pathways/facility space.  Should other tech (60GHz, LiFi, UWB [time-domain, not 
that lazy standard]) gain wide adoption, we'll all be sad, because two cables 
at a location probably won't help much in relation to the scale of the new 
challenge.

I've heard rumors from several sources about a multi-Gig network
interface model that can push 1Gbps  some-rate  10Gbps over Cat5e.

It would be a forklift upgrade to take advantage, but it was an
interesting compromise that would be appealing for an older installed
base.

And while I'm replying...  we are just doing single runs, but we're
doing Cat6 in recent projects and no 5e yet.  We haven't jumped to Cat6A
(yet).  We considered double runs with 11ac coming, and we're an Aruba
shop (they have two ports on newer APs) but we're rethinking some of
that mainly due to density / coverage collapse (if 11ad rolls out, with
it's 60Ghz band, coverage area/interference get to be a major pain).

We've also ditched 62.5u MM fiber for 50u OM3/OM4 similarly (there was a
ton of 62.5 done initially that is absolutely useless beyond 1Gbps).

RE: [WIRELESS-LAN] How many drops 802.11ac phase 2

[Jason Cook]

We have also always run 2 for AP's and everything else, it's always a pair(or 
4, 6, 8etc) whether for phone, computer, projects, ip camera, bms ,wireless 
etc. We've investigated singles a few time, but barely  a 20% drop in price so 
we have continued with 2. Each building has  a standard, so we remain with 
that, if the building is Cat 6, then the new duals are 6 if it's 6a then we run 
that. New buildings/reno's are all 6a. Often enough we have found the extra 
port gets used, particularly for lower ports, but even in roof space for ip 
camera's and projects for example and vice versa.

I generally agree at the moment though that it's unlikely we'll see any major 
requirement for more than 1Gbps in the near future Can we actually run 160 
channel width in high density? 802.11ad might be a different story, but that's 
a while away and would require re-design and new cabling anyway.

I may be crazy but what if the 2nd

  that it provides a second source of power. Right now 802.3at is
  good for wave 1, at least with Cisco, but do we know what the

  Not having to forklift 802.3at switching/mid-spans is a big deal,

We
have also always run 2 for APs and everything else, its
always a pair(or 4, 6, 8etc) whether for phone, computer,
projects, ip camera, bms ,wireless etc. Weve investigated
singles a few time, but barely a 20% drop in price so we
have continued with 2. Each building has a standard, so we
remain with that, if the building is Cat 6, then the new
duals are 6 if its 6a then we run that. New
buildings/renos are all 6a. Often enough we have found the
extra port gets used, particularly for lower ports, but even
in roof space for ip cameras and projects for example and
vice versa.

I
generally agree at the moment though that its unlikely
well see any major requirement for more than 1Gbps in the
near future. Can we actually run 160 channel width in high
density? 802.11ad might be a different story, but thats a
while away and would require re-design and new cabling
anyway.

phase 2

We
always run 2 cables per drop location (wireless or
otherwise).

  Bulk
  of the cost is labor, so makes sense to do so.

All,
I
  wanted to see how many people were planning on running
  2 drops to 802.11ac phase 2 access points?
  
Currently
  we are just doing a one for one swap when replacing an
  older a/b/g APs with 802.11ac phase 1 APs
  
When
  you have new construction, do you plan on running 2
  drops so when phase 2 come into play you will be all
  set for it?
