Cisco Wireless :: 5508 Unable To Telnet Over Port 8090
Aug 19, 2012
I'm having some difficulties configuring my Cisco WLC (5508) - ver 7.0.230.0 .I'm have multiple client device residing on same vlan associated to the WLC but unable to telnet over port 8090. However, when inter-vlan, client device able to telnet over port 8090.Say Machine A as application hosted machine and Machine B as client machine; [code] i should be looking on the WLC to allow telnet port 8090 over from Machine A to B within the vlan .
5508 controller is at the headquarters which can be normally pinged, telnetted, http'd and tftp'ed....at the remote site, controller can be pinged and http'ed but cannot be telnetted and tftp'ed.there is a complete tracert from the remote site pc all the way to the controller.from a switch at a remote site, the controller can be telnetted. but from a pc on the remote site (which belongs to a remote site vlan), it is unable to telnet and tftp the controller.all active components can be telnetted from the remote site, such as the core switches and routers at the headquearters, except the controller.upgraded the controller code to 7.2.xxx in headquarters but still unable to telnet and tftp the controller from remote site.is there any more settings on the controller for telnet and tftp?what could be the problem why the controller is not available for telnet and tftp from the remote site?
I am facing an issue with a cisco 877 router. I am not able to telnet to this router from outside using the public IP. I have also notices this works when the Nat is removed.
I am unable to Telnet/SSH/RDP from my inside network to my DMZ. I am not sure where the problem lies, I am able to use VNC from the inside to the DMZ (ports 5800, 5900), and also establish connection on Ports (26700-26899). I have a computer connected directly to the DMZ and those services work to all networks on the DMZ.I have attached Logs of successful VNC connections, unsuccessful RDP and Telnet sessions, and the running config.
We have a router that was installed a few months ago which has the following version: 15.1(3)T
I am unable to reverse telnet to a new ASA firewall, however when I move the console to a second older router with an older version of code I am able to reverse telnet
Are there any known bugs, issues with version 15.1. I use the following command as normal: telnet x.x.x.x 2001
I was unable to telnet in to a SQL server on port 1433 to test the connection from the client PC.the application could connect and this alone verifies it is working on port 1433 for sql.My question is how can a telnet command on a specific port be blocked ?
I have a cisco asa 5520. i need to forward telnet to a router on the inside interface. Here is what i have done so far but it doesnt seem to be working.
I have created an access-list that looks like this:
access-list 102 extended permit tcp any host 10.10.60.2 eq telnet
But when do this it still doesnt forward my request to the router at 10.10.60.2 . So just to explain what im trying to do. I use Putty, i am putting the outside interface IP into putty, selecting telnet and opening the session. i need the outside interface to see this request and know to forward port 23 to the router on the inside interface with IP 10.10.60.2. The ASA is running version: asa842-k8.bin
We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,
SG 300-52 Port Gigabit Managed Switch Firmware Version (Active Image ) : 1.1.1.8 Firmware Version (Non-active ) : 1.1.0.73 Boot Version : 1.0.0.4
I have a new 877 that I am using for internet traffic for 3-4 internet only devices.I also have a clean network that i want to insure no cross contamination. However I plan on rolling this out to many sites, but for management I was hoping to set up a reverse telnet to the console port from our one of my clean switches. which should allow me to keep the units seperated and allow me to manage changes etc remotely. Unfortunatly there is no Aux port on the clean switch (3560). Is there still a way to acheive this? can i configure one of the ethernet ports to connect to the console of the 877?
We have several routers that can only be accessed on telnet port 6066 (vice 23). I have no global exec privilege so I can not provide config.So my question is: how do you configure the router to accept port 6066 for telnet and deny port 23?
I am having issues with 'telnet' on port 2821 to a range of servers connecting through vlan interface from my core switch 6513 running s72033_rp-DVIPSERVICESK9_WAN-VM) version 12.2(33)SXH7, RELEASE SOFTWARE (fc3). The telnet on port 1556 and 13724 is ok.
I'm currently configuring a HP Laserjet P4515 printer. It has its own built in Jetdirect so, all that jazz is done.
I'm having issue when I telnet to port 9100. I type the typical Jetdirect commands: ? / MENU yet I receive no information back from any commands I type. Even configuration commands. Typically, all this gets me is a printed page (since 9100 is also the print port) with the commands I've attempted to type. Some garbled, some not.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode 3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
I have a 5508 WLC connected to 2950 Switch and the LAP 1262 connected to the same default VLAN. My AP's are able to join the controller since they are in the same broadcast domain but They are NOT able to download the image from WLC. When I am looking at the wireless TAB of WLC.. it says... Downloading Image.
what all needs to be done to make UP the APs. Also, Following is the error i am seeing at the AP.

I have an (AIR-LAP1310G-E-K9R) and I tried to join it to WLC 5508 but I'm facing an error, I get this error from the LAP 1310 console as below:

I had configured a Cisco 5508 series WLC. The APs used are Cisco 3502 LAP. The APs are configured to use DHCP for this ip addresses.
We had configured the DHCP server on the 2 Windows AD server previously and the APs were not able to get an IP address when the WLC was rebooted. To isolate the cause, we configured the DHCP server on a cisco 6500 switch. When we reboot the WLC, most of the APs are not able to grab an IP address. We had to remove and reconfigure the DHCP pool on the cisco 6500 for the APs to capture the IP addresses.
My colleague had feedback that they gotten a message that the DHCP pool had been used up. We tried to do a "show ip DHCP pool" but the switch did not recognise the command. IOS version used is Version 12.2(50r)SYS2.
We had a problem with the wireless client getting ip addresses from the windows DHCP server previously but problem was resolved after we disabled the DHCP proxy on the WLC.
What we are curious is why was the DHCP pool fully used on the Cisco switch and how could we check the number of addresses used other than running "show ip dhcp binding" and doing a count of the IP addresses?
Also why did we have to disable the DHCP proxy on the cisco WLC for the wireless clients to be able to get an IP address from the windows DHCP server?
We seem to be facing a number of problems with the DHCP functions for the wireless setup.
I have a 5508 wireless controller running version 6.0.199.4 (the image installed when the device was shipped) and I am trying to install by tftp version 7.3.112.0
The issue is when using tftpd32 gets to 82% transfered then fails with the error "% Error: Code file transfer failed - Error while writing output file"
I have a 5508 at a remote site and a 5508 at my main campus. I was doing some work on the remote site's controller, so I changed option 43 on our DNS/DHCP system, then applied an LWAPP template from NCS to the AP's to migrate them to the controller at my main campus (so users could still utilize the wireless at the remote site). They all moved over to the temporary (main campus) controller without an issue.
When I was ready to migrate the AP's back to their local (remote site) controller - I changed option 43 for each sub net that contained AP's @ the remote site to point back to their local controller's management IP address, pushed an LWAPP template again (pointing it to the local controller obviously) and apply template/reboot AP.
The AP reboots, disassociates from the main campus (temporary) controller, but when it comes back up a few minutes later - it associates BACK to the main campus controller it was on instead of to the remote site/local controller like option 43, the LWAAP template (and my frustrated screams) are now telling it to. I'm certain I'm just missing something.
Guestconnect SSID configured on 5508 WLC with Pass through athentication (NAC guest server). No issue with Laptops and Iphone/Ipad ver 4and 5. Only Iphone Ver 6 users unable to access Guest connect .
We have two SSID's Guest and Corp. We are using 5508 controllers.
The problem is that if an iPad user is connected to Guest SSID and then try to connect to Corp then it fails saying "Unable to connect to Corp". After 10-15 retires the same iPad connects successfully. The problem doesn't happen on windows PC. I have attached debug for one of the clients.
Background: Wireless credit card machines can't stay connected to the 5508 controller 7.0.116 / 1142 ap wireless system. MAC address of one of the wireless hosts is 00:12:0e:ec:ce:97. AP servicing them is d4:a0:2a:99:34:60. Hosts are able to connect to the network after a reboot and stay connected for random periods of time but then don't come back unless you manually reload them. I have 3 in total in the same room services by the same ap.
I have the output of debug client 00:12:0e:ec:ce:97. Output showed 802.1x 'timeoutEvt' Timer expired for station 00:12:0e:ec:ce:97 so I increased the value to 4000ms on the controller but am still having the issue.
Note that the output below is the state the client stays in after receiving the timeout (802.1x 'timeoutEvt') showing subsequent attampts. The only way to get them back on is a reload of the credit card machine.
I'm having an issue with the 5508 management port .. I can't seem to ping it from the switch connected to it .. ( the Show cdp command shows that the two can see each other .. but no ping is possible ! [code]
I connect a copper SFP on port 2 of WLC 5508 to a ASA 5510 firewall. The links between two devices are down. Since ASA 5510 only support 100 full, how do I change port speed on port 2 to 100.
We are trying to set up Out of band connection for Cisco 5508 WLC and when we try to ssh to the Service port from a remote switch, this fails. SSH or Telnet to the Management IP address works fine. The Service port and Managment IP are in the same IP scope but different subnet..i.e 172.16.10 for Management and 172.16.99 for Service port. Also, as this set up will be HA (AP SSO) in future, for which DHCP is recommended for the service ports, just wondering if SSh will be possible.
I have problems with an AP AIR-CAP1552C-E-K9 (MAC: 2c:36:f8:73:e8:a0 )this AP cannot join to WLC 5508 software version 7.2.110.0.The AP ever gets associated to WLC.
I saw timeout messages and this error message:
%CAPWAP-3-ECHO_ERR: capwap_ac_sm.c:5656 Did not receive heartbeat reply; AP: 2c:36:f8:73:e8:a0
I don´t see any connectivity issues between the AP and WLC thorugh HFC network.One time the AP join to WLC and I saw this messages in debug CAPWAP:

I have a 5508 WLC and 40+ LAP1142N APs spread across 19 locations that allows staff to connect to our private network via wireless. I recently deployed about 40 new laptops all identical make and model HP ProBook 4530's and all have the same client setup for the wireless. Out of those 40 laptops I have 4 that will not connect to the private network. However, these same laptops will connect to my public, open wireless network without issue. In addition to the 4 that will not connect all the others will prompt twice for network authentication.Now, I have about 10 other laptops that are not the HP model and all connect without issue and without dual propt. I don't think this is a wireless network issue but could be some type of issue with this model of laptop.
We use a wlc model AIR-CT5508-K9 with eight built-in ports. I would like to know if it is possible to change the speed of these ports down to 100Mb. At this time, they are set to auto and 1000Mbps.
I have 2 x 5508 Wireless Controllers, 1 mgmt port on each as standard. I noticied something different between these controllers running the same code.I can bound a physical port to the mgmt interface on one controller but not the other (both interfaces are untagged)see below, this config appears on one controller but not the other? Is this something to do with the initial setup? How can I add Phyiscal information to the other controller mgmt interface, I cannot delete the mgmt interface. Physical InformationPort Number Backup Port Active Port Enable Dynamic AP Management?
Since WLC5508 MGMT interface is configured a AP-Mgr at the same time, can I set a Backup Port to WLC5508 MGMT interface? Refer to WLC configuration Guide:
In the Backup Port text box, enter the number of the backup port assigned to the management interface. If the primary port for the management interface fails, the interface automatically moves to the backup port.
Note Do not define a backup port for an AP-manager interface. Port redundancy is not supported for AP-manager interfaces. If the AP-manager interface fails, all of the access points connected to the controller through that interface are evenly distributed among the other configured AP-manager interfaces
if I need to configure the backup port for MGMT interface, i need to remove the AP-manager on MGMT interface and create a network dynamic interface for AP-Manager ?
I have setup LAG for one of our 5508 controllers and have connected 4 of the 8 ethernet ports to a 4507 switch. After configuring 2 port channels on the switch we are receiving a host flapping error between the port channels and it seems to be causing a serious slowdown on the switch. When I shutdown one of the port channels the error goes away and traffic returns to normal. I have the same configuration at other locations with the only difference being the switches used are 3750G-12S and I do not see the host flapping error. It appears to only be a problem with modular switches.
One other thing of note: I read a Cisco white paper on LAG and it suggested creating the port channels over 2 different modules. For example, put ports G4/24 and G5/24 in port channel 1 and G4/25 and G5/25 in port channel 2. I tried this but I still got the host flapping error.
