Cisco Wireless :: AP 3500 Configuring Antenna Port Parameters
Oct 24, 2012
a customer has bought a new AP 3500 with external antennas and he would like use his old antenna AIR-ANT2485P-R.
We have the option to configure the antenna parameter in WLC under Wireless > Access Points > Radios > 802.11a/n or 802.11b/g/n for external antenna and and using only port A.
But if we enable only one port (Example: port A) we will get a warning message: Need to have at least both dual mode antennas (antennas A and B) enabled
Is it not possible to use an antenna like ANT2485P-N together with an Access Point like 3502E?

I am currently working on a project where I need to design a complete wireless solution for a huge building. I performed the wireless rf survey by configuring the wap's to broadcast a SSID and walked around gathering rf coverage data. When configuring the test WAP's i did not join them to a lan controller ( AIR-WLC4402-50-K9 ) but simply created a static ip and ssid to broadcast but modified the internal antenna gain to +128 to change the direction of the broadcast. There are two other ap's already joined to the lan controller on a guest network (configured by another contractor) but when I go into the lan controller web gui I do not see anywhere that allows me to modify antenna gain on the individual WAPs. Also, once the waps join the lan controller they dont seem to be accessible via web. How I can I modify gain per wap?

Region : India
Model : TL-WR941ND
Hardware Version : V3
Firmware Version : 3.6
ISP :
We need to configure the AP in such a way, only 1 antenna to be used & not other two, to meet some mounting requirements/limitations. Will I be able to do this using any test/debug commands?
Essentially I want this AP to be operating in 1x1 spatial stream, & with no antenna diversity, so that I can connect only 1 antenna & be deterministic about AP using only connected Antenna RF port & not others
With out configuring anything, when I connect only 1 Antenna, I observed that signal is fluctuating on Client Application & causing the applications traffic stream disconnect.

I just bought a DIR 615 (firmware 4.0) which I am using as an access point linked to a Netopia router. The Netopia has QoS enabled and needs to keep it, however I was hoping to use the DIR615 without QoS. I am using a ReadyNas Duo as storage for music, videos etc.Now, here are my issues which I think are all linked.
1) I have a very slow connection wireless, between 1'500 and 2'000kbits/sec download. This was not the case with my very old Linksys router
2) When I try to rip a CD from iTunes to the NAS, it brings up error messages of lost connection and impossibility to rip in the middle of the songs. I did not have that problem with the Linksys router neither.
3) I would like to change the QoS parameters to see how it affects this connection issue, as well as change other Wifi parameters, but they show up as greyed out and I can't change them. (I feel that the DIR 615 might inherit some parameters from the main router, since it is used as an Access Point).

I have a 2500 and I have successfully joined a 1600 AP to it; however I have noticed that I cannot enable CleanAir in the Global Parameters with just the 1602 AP joined. This feature was enable when I had my 2602 AP connected.So, is the problem that the 1602 doesn't fully support CleanAir? If that is the case, how do I enable CleanAir Express or is that something you can even enable thru the GUI?

I created a LAP Template in NCS to configure some new 1142 LAPs that were installed in a remote office. These LAPs need to be in Flex Connect mode with V LAN support. The template is being applied with partial success on every access point. Details of the partial success say the Flex Connect Parameters fail with the following error.
Provision Failure: { URL}.Object Not Found Exception cannot be cast to [URL]
Am I doing something wrong? The Flex Connect portion of the template has V LAN Support enabled, Native V LAN ID, and the Profile Name- V LAN Mappings configured.
Prime NCS version 1.1.1.24 Access Points are AIR-LAP1142N-A-K9s running 7.2.110.0

And the firewall allowing that traffic through and client software is working fine. However I need this FTP to be running on port 990 and anytime I change the NAT and the firewall, the external FTP clients connect but then drop when recieving the directory listing.

I just installed a HWIC-2T in a Cis co 3845 running IOS 15.1(3) T New build.The IOS self installed the port configuration including the command line "clock rate 2000000." I can edit everything but that entry using the CLI. When I enter the "no clock rate" it will not take in the running conf.

I have a DVR machine that I've been trying to carry out port forwarding to view cameras from outside the network. It lies on 192.168.1.31. The confusing thing is the ports. The configuration on the DVR lists a device port: 8000 and a http port: 80. I am torn between which port to forward.

I have a Cisco home rack lab which is behind my ASA 5505. I use my ASA to connect to the internet. My situation is I travel a lot for work, and I am unable to do my labbing practice. I am pretty new to ASA and would like to do a port forwarding to access my access server which is connected to my Cisco routers and switches.My network topology is this: (internet)-------(ASA 5505)----------(3550)-------(CM32 Access Server)----------(Cisco Rack) This is how I setup my remote access:
Code:
ssh 0.0.0.0 0.0.0.0 outside

I have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)
Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200
I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.
Restrictions:
1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.

I have configured SSL offloading and redirection on a 4710 appliance. Everything works fine. The issue I am facing is that some parameters in url are getting lost.
I have https://%h/%p configured as a redirect server which works fine as far as hostname and path is concerned. i.e. full hostname and path are preserved, but that there are some parameters after the full path in encrypted format which are getting lost. I think 307 redirect can resolve this issue but ACE does not support that.

I configure two WIC-1DSU-T1-v2 interfaces with a T1 crossover cable. What are the mimimum configurations to do to communicate from LAN1 (int fa0/0 of one 1841 router) to LAN2 (int fa0/0 of the second 1841 router) ?
Do I need a routage protocole ? And if yes wich one ? Interne or externe (RIP or BGP) Or static route is enough ? Also, is that I should put a encapsulation, like ppp ? Is it neccessary on a point to point line ?
Finally what about the following commands, do I need it ?
service-module t1 clock source internal
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs

We've been configuring our swtichports as follows for our 7945 and 6941 type VoIP Phones, but are having problems witht the 6901.
VLANS
Vlan 900 is a VoIP VLAN
Vlan 999 is a NULL VLAN and is shut down:
interface g0/1
switchport access vlan 999 {VLAN to direct data traffic to the bit bucket becuase a PC shouldn't be connected to this port}
switchport mode access
switchport voice vlan 900
mls qos trust cos
spanning-tree portfast
The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.
switchport voice vlan 900
mls qos trust cos
spanning-tree portfast
solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?

I have problems with setting the snmp retry / timeout parameters for our devices. I managed to import our devices with bulk import , but after it I realized that for some devices the snmp retry / timeout values were different ( created the bulk file with 3 retries and 30 sec timeout , but in the system the appear with 2 retries and 1 sec timeout). I tried to change it manually , but after a while it goes back to the wrong values.

I have had this router for about 5 years now, I had problems setting it up from the start as I was fairly young but I eventually found a way around it - no problems since. Through memory I am sure I had this problem previously but I had the disk to give me guidelines on what to do(which I don't have any more). I have phoned up virgin (my ISP) and they said it was an issue to do with the router, to which I searched into the routers address, in this case 192.168.50.1. Scrolling down, I noticed that under the WAN section it says:
MAC Address:00-16-0A-09-CC-69IP Address:0.0.0.0Dynamic IPSubnet Mask:0.0.0.0 Default Gateway:0.0.0.0 Obtaining Network Parameters...DNS Server:0.0.0.0 , 0.0.0.0
I have spent a good part of today trying soloutions to get this to work again but I just can't seem to find a way around it. As I said, the router has been working fine for pretty much 5 years now and I really do not know why the WAN went. In addition, it was set up wireless. How can I obtain the newtork parameters?

Following the chat with the technical support of CISCO.In few words, the LINKSYS X3000 is the only router in the world that can't shows the DSL line parameters ( SNR and LINE ATTENIATION ) so you can't evaluate the line quality without using another router.... INCREDIBLE!!!!Let's see how long it will be before the firmware update!Me: simple question: is rather embarrassing but I can't find the SNR value (Adsl status) in the Linksys X3000 interface. Same for the Line Attenuation values. These are the standard DSL information and they are essential to evaluate the DSL line quality.Unfortunately, you are right, these parameters are not available on the Gateway (X3000) Setup page.Me:It's unbelievable I use routers for my work and this is the first product that can't shows the DSL line parameters...The only parameters available under DSL Connection Subta are Status, Downstream Rate and Upstream Rate.Me:Do you think it's serious? The price of this product and the target to which it is oriented suggest a more professional approach.I agree, but as of now, this is how it is however, you need to keep an eye on future updates for the device that might include these paraters/features.Me:Please could you send a notification to the DEVELOP TEAM to quickly update this product FIRMWARE and close the gap that separates it from other products in the same category?

I would like to configure a 3750 switch port to be able to use two vlans. I know you can do this with a voice and data vlan, but what about two data vlans ? Say I have two devices, one on a 10 subnet and the other on a 172 subnet, but i only have one wall jack for both devices to plug into. So I use a mini switch to connect both devices and connect the switch to the wall jack; and of course this all leads back to one switch port. When I go to enter the switchport access vlan 172 cmd, how would I also make it so the device on the 10 subnet could route out ?

Purchased a 2911 router for a customer, and I'm sure I'm missing a module here.
Teleco installed T1 and left connection to smart jack. Router only has 2-3 copper ports.
Can I get away with configuring the blackbox with RJ45 to the copper port on the router ethernet or do I need to purchase a HWIC ?

Just loaded the 7.2.103.0 software onto the brand new WiSM2. Going throught the options and have found that under the global parameters for 802.11a/n, 802.11b/g/n radios is now the "Maximum Allowed Clients" option. The allowed setting is from 1 - 200 clients.
Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
Doesn't seems to make sense... I have the 500 AP license on this WiSM2... I know this option used to be an optional setting under a WLAN in previous releases.
