Cisco 5520 and 8540 Wireless Controller

Troubleshooting Guide

Overview of Cisco 5520 Wireless Controller

The Cisco 5520 Wireless Controller provides centralized control, management, and troubleshooting for

high-scale deployments in service provider and large campus deployments. It offers flexibility to support

multiple deployment modes in the same controller: for example, centralized mode for campus, Cisco

FlexConnect mode for lean branches managed over the WAN, and mesh (bridge) mode for deployments

where full Ethernet cabling is unavailable. As a component of the Cisco Unified Wireless Network, this

controller provides real-time communications between Cisco Aironet access points, the Cisco Prime

Infrastructure, and the Cisco Mobility Services Engine, and is interoperable with other Cisco controllers.

Logging in to CIMC

CIMC is a separate management module that is built into the motherboard. CIMC has its own

ARM-based processor which runs the CIMC software. It is shipped with a running version of the

firmware. Users can update CIMC firmware through the Firmware Update Management page. You need

not worry about installing the initial CIMC firmware.

Logging in to CIMC

Before starting

Check if Adobe Flash Player 10 or higher is installed on your local machine.

Step 1 Type or select the web link for CIMC in your web browser.

Step 2 A security dialog box is displayed, do the following:

a. Optional: Check the check box to accept all content from Cisco.

b. Click Yes to accept the certificate and continue.

Step 3 Enter your Username and password in the log in window.

Step 4 Click Log In.

Setting up CIMC

Setting up CIMC for 5520 and 8540 Wireless Controller

To setup the CIMC interface follow the given steps:

Step 1 Connect the CIMC cable to the 10/100/1000 port in base T.

Step 2 Use the command imm dhcp enable on WLC CLI to enable DHCP to set the IP.

Step 3 If DHCP is not available, use the command imm address <ip address> <net mask> <gateway ip>.

View the IP and details, using the command imm summary.

Cisco 5520 and 8540 Wireless Controller Troubleshooting Guide

Setting up CIMC

Note Default password will be either ‘password’ or ‘Cisco1234’. You can change this via the username

command

CIMC Configurations that are required for reliable WLC operation

Note Once the user logs in to CIMC the following should not be changed. This will cause issues for WLC

operation.

•Do not change the NIC mode to shared. It should be in dedicated mode

•Do not change the FlexFlash Mode

•Do not change the SSD/Virtual disk settings

•BIOS parameters should not be changed

Expectations when logged in via CIMC

•FlexFlash is configured for RAID but only one flash is populated this causes CIMC to show the

FlexFlash as degraded.We can safely dis-regard the FlexFlash degradation warning in our case.

•Expect to see only one CPU populated

•Do not configure Software Raid on SSD
