can't access to cisco 5508 web management on service port

Hello, i have dual 5508 installation in HA mode. I configured ip on management and service interfaces and connect them to the switch. RP port on controllers connected to each together. HA status is ok, i can access to the ssh but not to the web GUI on service port nor management. Please help what could be wrong?

Can you clarify this response:

+ No, i`m using gateway

The service port can only be accessed on the same subnet. It has no concept of a default gateway therefore any traffic you are trying to send to it from an outside subnet will never make it back.

I don't know the reasoning behind this and it's annoying to be sure, but that is definitely the case for that particular interface.

Are you able to access the WLC from wired network? Ar e you trying to access the WLC through telnet/SSH or GUI? In order to access the WLC you should use the managment interface of WLC.If you are trying to access this via GUI ensure that you have enabled the http server using "config network webmode enable" from the command prompt. Also you should be able to see the status of webmode and managment by wireless interface is enabled using "show network summary" command.

Hello! I`ve read this topic already but it`s not my case, cause i would like to manage via service port not wireless.

- Are you able to access the WLC from wired network?

+ Yes, only ssh

Ar e you trying to access the WLC through telnet/SSH or GUI?

+ all of them, but works only ssh

+ did it already

What exactly happens when you try to reach the WLC via the web GUI? Timeout? Connection refused?

Are you specifying https://<IP>; ?

Are you trying to ssh/http into the WLC on the same subnet as the service port? If not, I'd recommend tracing packets to see why the ssh connections are making it through but the http/https attempts are not.

Hello! I`m trying to acces service port IP http://X.X.X.X but it says connection time out. And in the same time i can access by ssh to this address

Specify https://<IP> instead of http://<IP>

Hello! Thanks for your advice with https but it didn`t get access. Now i see the message:

Unable to connect

Firefox can't establish a connection to the server at X.X.X.X

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Are you on the same network segment as the management or service port?

Do you have a CPU ACL setup on the WLC that would be restricting connections to it?

Do you have other ACL's or firewalls that could be blocking the traffic?

Assuming you are not on the same network segment and you can get in with ssh but not http/https I would recommend tracing the packets as you try to connect via http/https to see where the breakdown is.

- Are you on the same network segment as the management or service port?

+ No, i`m using gateway

+ Tracing is ok, there are no firewalls. I`m sure the problem is on the controller side. Are there some debugging methods?

the service port is ONLY accessible from the same subnet

I wonder where Javier moved this thread to... WLCCA?
Anyway Eric, the service port is a 'mother-board down' interface that supports telnet/ssh interface almost as soon as the hardware wakes up. before the app is alive. Yes one can GUI into it whenever the unit is online in a non-redundancy mode. However you and I have no purpose in the Standby unit.. other than curiosity. All tweaks are the responsibility of the Active device of a pair. So only the Active device GUI is alive. besides the IP's of both units are the same. Only the RP, RM and SVC ip's remain 'different' all other ip's are identical on both unit.
"the service port is ONLY accessible from the same subnet" if the host switch knows the default gateway for the segment your service port is on, it will work. Mine does. but the usually only the switch management segment has a default gateway so packets get lost.
