WiSM Service IP vs Management IP

Hello Hamilan,

please check the following two links:

1) management interface

http://www.cisco.com/en/US/docs/wireless/controller/7.0MR1/configuration/guide/cg_ports_interfaces.html#wp1117168

The management interface is the default interface for in-band management of the controller and connectivity to enterprise services such as AAA servers. It is also used for communications between the controller and access points. The management interface has the only consistently "pingable" in-band interface IP address on the controller. You can access the controller's GUI by entering the controller's management interface IP address in Internet Explorer's or Mozilla Firefox's address field.

For CAPWAP, the controller requires one management interface to control all inter-controller communications and one AP-manager interface to control all controller-to-access point communications, regardless of the number of ports.

2) service

http://www.cisco.com/en/US/docs/wireless/controller/7.0MR1/configuration/guide/cg_ports_interfaces.html#wp1117020

he service port is controlled by the service-port interface and is reserved for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. It is also the only port that is active when the controller is in boot mode. The service port is not capable of carrying 802.1Q tags, so it must be connected to an access port on the neighbor switch

- now with WISM the situation is little bit different.

WISM Service port is used also for carrying communication between WISM module and 720 Supervisor.

the communication is carried using WCP protocol.

- managment , is the WLC access IP that you can telnet / HTTP. and also all intercontroller communication carried over management IP.

Trying to answer your questions:

1) Which IP is uded to communicate AP and which used for data?

the communication between AP's and WLC is done using AP-Manager interface.

except discovery request sent on management.

now data clients are carried inside LWAPP/CAPWAP tunnel.

so client connect to AP.

AP tunnel that client to WLC using the LWAPP/CAPWAP tunnel.

2) which range wireless client will get?

this depends on which VLAN's you configure on WLC.

you can map the WLAN to managment interface ->> so clients are in same VLAN as management.

or you can map it to any dynamic interface (new VLAN) you create. so they take IP from That VLAN.

Kind regards

Talal
