Installing Wireless Controller on Cisco SRE
First Published: April 14, 2011Last Updated: April 14, 2011The Wireless Controller on Cisco SRE enables systemwide wireless functions in small to medium-sized businesses and branch offices. This document describes Wireless Controller installation on Cisco Integrated Services Routers Generation 2 (Cisco ISRs G2) running Cisco IOS Release 15.1(3)T.01 or a later software release. The Wireless Controller is supported on the following modules:
•
Cisco SRE Internal Service Module-Services Ready Engine (Cisco SRE ISM): ISM-SRE-300
•
Cisco SRE Service Module-Services Ready Engine (Cisco SRE SM): SM-SRE-700, SM-SRE -900
Although the Cisco ISR G2 can support more than one Cisco SRE, only one Wireless Controller per host platform is supported.

Cisco Wireless Controller Software Support
Cisco Wireless Controller requires the following software:
•
Cisco Wireless LAN Controller (WLC) version 7.0.115.0 and higher versions
•
Cisco Wireless Control System (WCS) version 7.0.172.0 and higher versions
•
Cisco IOS Release 15.1(3)T.01 and later releases
Limitations and Restrictions
•
Wireless Controller on Cisco SRE does not support the following features:
–
Datagram Transport Layer Security (DTLS) data encryption
–
OfficeExtend Access Point (OEAP)
•
Wireless Controller on Cisco SRE supports a maximum of 20 Hybrid Remote Edge Access Point (H REAP) groups with up to 25 access points (APs) per group.
•
The following restrictions apply to MGF and Wireless Controller on Cisco SRE:
–
MGF is enabled on the Cisco SRE only after Wireless Controller is successfully installed. MGF is not enabled on a blank Cisco SRE.
–
The interface on the EtherSwitch module must be in the same VLAN as the Wireless Controller on SRE to utilize MGF; otherwise, interVLAN communication still uses the PCIe interface on the Cisco SRE.
–
MGF check happens on each router bootup or reboot. You must reconfigure MGF if an EtherSwitch that does not support MGF is added or removed. For example, if you add a Cisco EtherSwitch HWIC or Cisco EtherSwitch Network Module switch to the host router, MGF will be disabled. All data traffic will no longer use the slot/1 interface of the Cisco SRE.
Preparing to Install Wireless Controller
Perform these tasks to prepare for installing Wireless Controller on the Cisco SRE:
•
Configuring Server for Installation Files
•
Placing Installation Files on Server
Configuring Server for Installation Files
Decide on the location of a directory for the Wireless Controller installation files. This location can be either an FTP server or HTTP server. These Wireless Controller installation files are later remotely accessed by the Cisco SRE module during the installation of Wireless Controller.
The following two examples show how to set up FTP server software on Windows or HTTP server software on Linux.
You may also choose to use different HTTP or FTP server software than the software that is used in these examples.

The following example shows files being installed from an FTP server. To install files from an HTTP server, change the url in the service-module sm install or service-module ism install command
from "ftp://<ftpserver>/AIR-WLC-SRE-K9-7.0.115.0.aes"
to "http://<httpserver>/AIR-WLC-SRE-K9-7.0.115.0.aes".where, an example of <ftpserver> is: myuser:mypassword@172.19.150.32
an example of <httpserver> is: myuser:mypassword@192.168.1.2:8000
In the following example, the following IP addresses are used:
•
FTP server: 172.19.150.32
•
Cisco SRE: 10.1.0.40
•
Cisco SRE gateway: 10.1.0.30
Follow these steps to verify connectivity between the Cisco SRE, the Cisco SRE gateway, and the FTP server:
Step 1
Verify connectivity from the router that will host Wireless Controller to your FTP server:
Router# ping 172.19.150.32Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 172.19.150.32, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 msRouter#Step 2
Verify connectivity from the host router to the Cisco SRE:

Troubleshooting Tips
TFTP/FTP/HTTP server can not ping the SRE
1.
Check if NAT configuration is applied on interfaces.
2.
Check if access list is correctly configured.
Cisco SRE and [interface ism | sm ] 0/0 interface can't ping each other
1.
Check service-module ip address is configured on Cisco IOS software.
2.
Check that the service-module ip default-gateway command is configured.
3.
Check that IP address of SRE in SRE bootloader, using show config command, has same IP address as that configured by the service-module ip address command.
4.
Check that TFTP server IP address in SRE bootloader, using show config command, has same IP address as that configured by the service-module ip default gateway address command.
Example:
ServicesEngine boot-loader> show configIP addr: 40.1.0.30Netmask: 255.255.0.0TFTP server : 30.1.1.115GW IP addr: 40.1.0.2Default Boot: chainloaderBootloader Version: 2.1.29Bootloader Name: bootloaderDefault Helper-file: AS_SMWLC_7_0_114_9.aes.installerDefault bootloader: secondaryCannot access Wireless Controller via HTTPS (GUI)
If NAT is used, check that extendable TCP and UDP port 443 pair are configured.
No connectivity between Wireless Controller management interface to host interface and external network
1.
If MGF is enabled, check that Wireless Controller Management Interface is in the same subnet of the native VLAN on the Cisco IOS software side.
2.
Verify that interface [ism | sm] slot/1 is in no shutdown and has switchport mode trunk configured.
or
1.
If MGF is disabled because of the presence of a legacy EtherSwitch module, check that VLAN sub-interfaces are created and bridged to use the BVI interface.
2.
Verify that encapsulation dot1q and `bridge irb are configured.
Cannot add Wireless Controller to WCS
1.
If NAT is used, check that extendable UDP port 161, 162 are configured.
2.
Debug the connectivity issue between WCS and Wireless Controller if they are not in the same network.
Cisco SRE can ping the FTP server but installation will not start
1.
Check username and password.
2.
Check the directory or path to the files on the FTP server.
