I have a Cisco 5508 setup at a host site with 3 other sites connected using hreap on 1252APs. When doing testing of network speed I find that the throughput from the wireless to wired network is at about 18mbps yet the same test on wired side is 85-100mbps and wireless to wireless is 18mbps
View 4 RepliesI have a wireless network with two WLC 5508 controllers and 220 LWAPs in the same location as the controllers. All APs are currently in local mode. I run a few guest networks as well as some other client networks. One client in particular uses their network to connect mobile machines to their VLAN. The only issue is that the machines do not have wireless adapters. Instead, the manufacturer put inside the chassis, a D-Link WGB, which has an ethernet cable, you then have to plug into the ethernet port. These devices cannot seem to connect to the network. I have found, the WGBs do associate on the network, but the wired client behind it cannot pass traffic onto the VLAN. I have also tried connecting PCs with different SOHO style WGBs from different manufacturers with the same result.
After going through Cisco's documentation, I found that using 1230s in WGB mode can resolve this issue since they use IAPP to communicate the MAC table of the wired side clients they service back to the controller. I have configured a 1230, and used it as the WGB for the client machine instead of the D-Link and it does seem to work, but this would mean configuring a considerable number of 1230s to hand over to the client.
The first question would be, Is there something I am missing that I would need to do in order to allow SOHO style WGBs to forward wired side client traffic onto the network while LWAPs are in local mode? Or would the WGB NEED to support IAPP?
The second question is that, I may have found another solution to this already, but would like some input prior to committing.
This client also uses these same machines with the same WGBs inside the chassis at another location where the client operates the network themselves. They also use the same WLC model with the same version, and same APs. The only difference is that they use H-REAP mode with local switching.
I also tested this idea, and it seemed to work. With the AP in H-REAP mode, and the client's WLAN set to local switching, the machine and WGB connected with no problem.
So the question with this, would be; would there be any disadvantages in running all 220 APs at this location in H-REAP mode? What would I be losing if anything? Also, I would like to keep all other WLANs centrally switched.
I understand what the difference would be for this client's WLAN if I ran in H-REAP mode with local switching, but what would the difference be in the other guest WLANs if I set them to be centrally switched? (Is there any difference between running APs in local mode vs running APs in H-REAP with central switching?)
I have been having an issue with random AP3602I's in HREAP mode disassociating from the 5508 controller. These AP's are in remote offices with 70Mb WAN back to the controller. Randomly one or two AP's disassociate from the controller and I have to bounce the switchport to bring them back online. The WLC is running 7.2. Again this only occurs to one or two AP's not all of the AP's.
View 8 Replies View RelatedWe have standart wireless deployment with 24 APs (1240G model) and wireless controller 4402-25 placed on same site.Most of clients (WMS RF terminals ) works with one WLAN (WPA2-PSK) and constantly roam over warehouse , and that works great.
But for better survivability(when controller dies) we are trying to configure HREAP on our APs with local swicthed local auth WLAN. And that also work , but client roaming occur much more slowly and RDP connection to WMS APP server sometimes stuck for 2-5 sec.Disabling "local switching" checkbox for WLAN make roaming almost momental.
And slow roaming are price for controllerless HREAP design ? And for fast roaming and survivability we must use N+1 wlc?
I have a new deployment of 44 3502i AP's in 3 buildings at one of my campus'.The 5508 wlc is running latest 7.0.116.0 code.I have some users who take their work with them as they go from location to location on this campus.They need to be able to smoothly switch from AP to AP without having to reauthenticate each time the next AP takes over in the handoff.On the ssid in question we run 802.1x back to 1 auth server; there is no failover auth server.All APs are in one AP Group.My thought is to add all 44 of the APs to one HREAP Group.

The FIOS (ActionTec) router provides the full advertised speeds with any speed test service I try. But with the 2500 connected to the FIOS router I get download speeds about 3MB. The MTU on the linksys is 1500. It's connected correctly and is running it's own DHCP server. (Why am I doing this?

When trying to access a database server using tcp port 1521 (sqlnet) it is about 10 to 20 times slower than when the database is not behind the firewall. We've been running the same software on a database behind an ASA 5520 running version 8.0 (3) with no problems for years. When I check the cpu usage on the 5540 at the ASDM home page, it is rarely above 20% and never above 30% while this is being tested. I tried testing ftp throughput over the same interface and it was normal with ~320 Mbps average rate transferring a 500 MB file.
View 6 Replies View RelatedI recently setup our small office network using the following setup:
Cablemodem <--> router <--> 1231AP(role root bridge with wireless clients) <-> 1231AP(role non-root bridge with wireless clients)Code on both APs: 12.3(8)JEE.Office network generally has less than 3 wireless clients connected at any one time to either AP. AP's are a mere 50' apart; clients are all less than 30' from either AP; they all show excellent signal and connected at 54mbps signaling rates.
All is/has been working very well & very stable with the exception of speed. We have business class service from RR, approx 25mbps dl, 2mbps ul. Any hardwired client to the router switch ports are able to download at speeds averaging 23mbps. Any wireless client connected to either AP is never able to exceed download speeds of 5mbps. With no other wireless clients connected except my one test client, I was not able to exceed 5mbps throughput from either AP that I connected to.
I can confirm that the ethernet connection between the router and root bridge is up at 100mbps-FD and not showing any errors: [code]
Are these very slow thoughput speeds normal of this hardware combination?I did much searching/googling and found claims that by eliminating TKIP it almost doubles the actual wireless speeds our clients can obtain.
I am experiencing slow throughput on a L2L IPsec tunnel that we have between one of our offices on the west coast (WC) US and another on the east coast (EC) US. The tunnel endpoint on the WC resides on a 5510 and a 5545x on the EC. The DIA circuit speed on the WC is 45 Mbps and 200 Mbps on the EC. The throughput of this IPsec tunnel is maxing out at approx. 4 – 5 Mbps. The utilization of the DIA circuits at both offices is under 5% when running various FTP test transfers. Both devices have low memory and CPU utilization.
We have a 2nd office on the EC (45 Mbps DIA) which I built a tunnel on a 5510 with the WC office and it is experiencing the same slow throughput. In covering all my bases we have a colocation facility on the WC and in building a tunnel between the 2 WC offices I WAS seeing close to full line rate speeds over the tunnel. Additionally, I built a tunnel between the 2 EC offices and I saw full line rate speeds. With the physical distance between the WC & EC offices I would expect some loss in throughput speeds but I would not expect it to drop as low as 4 – 5 Mbps. In thinking something may be up with the 5510 in our WC office we shipped a 5505 to the WC office and we built the same IPsec tunnels on it and it is experiencing the same.
In working with our support vendor to try and solve the WC <-> EC throughput issue they had me change the MTU, TCP mss, DF-bit, types of encryption/hash on the IPsec tunnel but nothing has resolved it. We are not showing fragmentation or PMTU issues on the tunnel. In contacting the ISP of our WC office they mentioned that they do not have any type or rate limiting in place. Our WC ISP had a CCIE review our configurations but nothing was found.
I have a device manufacture there are requesting the following change on a customer's WLC 5508.
-config advanced eap identity-request-timeout 60
-config advanced eap request-timeout 60
I have studied many guides but I can't find out if there is a down-side to setting the timeout this high.Could it result in slow roaming or re-authentication if there is a connection error? The customer have large areas with high client density and some outdoor areas with low client density.
We find that some of the utilized iPads (iPad2, iOS 5) have a significant delay to connect to the WiFi after waking up.. though some of them show the WiFi-icon instantly after wake-up.. That is causing the crestron App on it to "malfunction", which is to say that it can't connect to it's server and goes back to home screen to allow re-connect..
WLC and LAPs using the latest software (7.2.103.0).. encryption is WPA2/PSK..
I changed the WLAN to use 802.11g only.. changed Beacon-Time.. changed encyption.. changed WMM settings..Alas, the iPads that expose this behaviour do not show any difference with the changes..

View 15 Replies View RelatedWhen transferring traffic between two VLANs my throughput rate seems to drop to about 1.5 - 3.0 megabits / second.
My setup is like this...
Two Nexus 5020 switches. (switch01 and switch02)
Two Nexus 2232PP fabric extender switches. (switch03 and switch04)
Two Dell R815s with Chelsio and Intel NICs. (host1 and host2)
The servers run Xenserver 6.0, but as part of testing with this I've tried installing RedHat 6.2, VMware ESX 5.0 (vsphere 5).
The issue occurs when using trunking and transferring data from one VLAN to another. Example...
VM1 is in VLAN401 with an IP address of 10.100.40.40. The VM is on Host1. VM2 is in VLAN402 with an IP address of 10.100.50.50. The VM is on Host2.
I've been using a network throughput tool called iPerf to test and I find that I can only get a throughput rate of about 3.0megabits.
If I switch VM2 to be in VLAN401 with an IP address of 10.100.40.41 I get a throughput rate of about 6.7gigabits/sec.
In the above scenario, I'm using a Layer3 interface on the Nexus 5020, but in production we use a Vyatta virtual firewall.
I worked with Citrix for about 3 months and that was a dead end.
I realize this is just a small business switch, basically a rebranded Linksys, but why I'm only getting 200Mbits/s
- 48 port - 10/100/1000 , set to standalone mode
- 3 separate PCs on this switch , all are fast machines with Core 2 duo / plenty of RAM etc...
- all 3 auto-sense 1Gbps connection
I use iperf tool for bandwidth testing and no matter which PC I pick as server, which as client I get about 150 to 250Mbits/s
I am not looking for full 1000 here, but 200 seems rather sad....
- jumbo frames seem to make no difference
- I am using TCP test in iperf , standard no extra flags , 10 seconds, 20 seconds or even 30 seconds all come out the same.
- wiring is shady as some of it is just Cat5 , but when going from one laptop on the switch to another with brand new Cat6 cables I STILL only got 200.
I have quick question about wlc software version upgrade : currect version of 5500 WLC : 7.0.220.0,However i am planning to upgrade to version 7.2.110.0,currectly all remote site AP's are connected to this WLC , nearly 150 AP's all are in H-reap mode however once i upgrade to 7.2.110.0 version , all default should come into Flexconnect mode.Do i need to make any configuration or any changes in AP's to get Flexconnect mode or will it be default mode as Flexconnect mode in new version of WLC ?

View 14 Replies View RelatedI have a tale of woe for you who may be considering Hybrid REAP with local switching.
My client has a varied configuration, but the requirements basically screamed HREAP with local switching. They have 15 sites, had already purchased a single WLC 4404 and they needed between 4 and 24 APs at each of the sites. Each of these locations are connected by a WAN link of good quality, but only a single link so there is no assurance of availability; the client has local resources so it would be useful if wireless stayed working during an outage.
So I setup the WLC for HREAP local switching. I setup AP Groups VLANs, but I noticed it had no effect on the VLAN allocation for HREAP. This was unfortunate, because not every site has the same VLAN configuration - some sites had a L3 switch and others only a L2 switch. But I suffered through this and configured each AP manually with the appropriate VLAN mappings.
The infuriating thing, is now that they have bought a second WLC 4404 (they expect to increase the number of APs beyond 100) all these VLAN mappings are messed up when APs connect to the second WLC. I've been going through them one by one again - it is really unfortunate that the AP Groups VLAN mappings don't apply to HREAP local switching.
I'm going to get back to the next 80 APs - but if some of you have a system for handling the VLAN mappings of a large number of APs.
I'm configuring AP in Hreap mode. Objective for me is th have a "plug & play" installation method for HREAP. I configure on HREAP AP, Native VLAN set to 1 and the WLAN and Vlan mapping for the current wlan is set to 1 too. WLC version is 7.0.230.0 and AP version is 12.4(23c)JA4
on my cisco switch (WS-C3560-24PS with 12.2(55)SE1), the port configuration is as below:
switchport trunk encapsulation dot1q
switchport trunk native vlan 45
switchport trunk allowed vlan 45,74
switchport mode trunk
no logging event link-status
no logging event power-inline-status
no snmp trap link-status
spanning-tree portfast trunk
spanning-tree bpduguard enable
AP receives a DHCP IP in Vlan 45 and users connected in vlan 45 too. I would like to undestand why the AP is working properly because normally vlan 1 is not configured as allowed vlan on my switch and the native vlan is dedicated only to untagged ethernet packet.
I have one cisco wlc 2112 with ios 7.0.230.0 with license to support 12 access points. My access points are nine (9) lap1231ag and one (1) lap1310.I just have one wlan (ssid). My scenario of deployment is in layer 3. I have one interface management and ap manager in the WLC. All my Access Points have differents ip address that WLC. I need to configure a unique ssid to associate my six (6) dynamics interfaces (each dymanic interface with different vlan subnet).Each wlan profile (ssid) should have the same security in phase 2 (wpa2/psk). My cisco access points don't support hreap. My wlc support only (4) interface into an interface group, and i need six (6) dynamics interfaces.
View 6 Replies View RelatedI'm doing some throughput calculation test between a wireless client and a wired desktop computer, and I'm a bit confused about the result i've got. According to the client's card and the WLC, the client is connected to 802.11g, at a speed of 54Mbps. To perform my test, i'm using IPERF (available here [URL) The result is as follow:

As you can see, i'm far away the maximum theorical speed of 802.11g. Any software wich is able to test the throughput of a connection? The client wireless card is a Dlink DWA-652 and the wlc is running code 7.0.116, the AP is a cisco LAP1042N.
If I do a speed test (bandwidthplace.com) while connected to a remote locations 1140 standalone access point, the download/upload speeds are roughly 100kbps. There are no other devices connected to the access point at the time. Wired PCs on the LAN that the access point is connected to are not having a problem.Pings from the laptop, through the access point, to our central WAN router are at <10ms.The WAN circuit (remote location to headquarters) is 5Mbps. No congestion.Circuit out from headquarters to I'net is 50Mbps. No congestion.Access point and router interfaces show no errors or collisions, etc. The configuration is the same as 28 other standalone access points in 28 different LANs on the WAN. They have no problems.
View 5 Replies View RelatedWhat is the maximum throughput of a 2600 AP when using CLient Link 2.0. I see that the datasheet states that it is 450mbps, however, from my understanding of transmit beamforming (client link 2.0), when traffic is "beamformed" to a client it cannot use spatial multiplexing on the same antenna as well. If this is the case, with the 2600 only having 3 transmit antennas, does this mean that the max throughput to a client when using clientlink is 300mb ?
If not, how the AP transmit at 450mbps and beamforms at the same time.
I have two WLC5508 controllers running 7.0.230.0, which having the two of them probably is inconsequential because all the APs are added to only one controller. The problem I'm facing is that I have several LAP1552E's deployed throughout my facility, and I have several that are doing Ethernet bridging to some Cisco switches using G0. In this, I have a PC at the end of one of these switches, and using Iperf and PingPlotter to get some metrics, and what I'm seeing is >400ms latency with <3 Mbit throughput to the PC. On the 802.11a radios I have 18 Mbit set as mandatory, with everything below disabled and everything above Supported, with all MCS indexes under 802.11n enabled.
My channel is set to 161 with a 40 MHz channel-width, and a power of 3 configured.After many days of trying different power settings, channel settings, and such, I can't get better results than above and my channel utilization stays > 75% at all times. I do have video cameras attached to the other bridges switches, and have video QoS set to Bronze and the cameras configured to ~ 1 Mbit bandwidth maximum. Also, average RAP-MAP distance is ~ 1100 ft and average MAP-MAP distance is 400 ft, with the longest RAP-MAP being 1400 ft and MAP-MAP distance being 875 ft.
I have 2 - 1410 bridges ( point to point) between two buildings approx 600' apart. They seem to be aligned well ( Signal -52dBm, SNR 41 ) and have been very reliable. However, I cannot seem to run more than 26Mbps thru them.is there any recommended tweaking that can increase my throughput ?
