The post-obit example shows the startup configuration being copied to a TFTP server:

Copying from Flash Memory to a TFTP Server: Example

The post-obit example uses the

dir flash0:
privileged EXEC command to obtain the proper noun of the system image file and the

copy flash0: tftp:
privileged EXEC command to copy the organization image to a TFTP server. The router uses the default username and password.

Define the WAN Interface on the Router

To define a WAN interface to connect to a TFTP network for image download, follow these steps, starting time in global configuration mode.

DETAILED STEPS

Secure an IP Address on the Access Point

To secure an IP address on the admission point and then it can communicate with an external server where a Cisco IOS epitome is located, use the DHCP server functionality on the router. The host router provides the access point DHCP server functionality through the DHCP pool. The access indicate communicates with the external server and setup option 43 for the controller IP address in the DHCP pool configuration.

Instance

The following example shows a dhcp pool configuration:

Confirm Connectivity and Settings

Perform the following steps to confirm connectivity.

1.

Ping the external server from the router to confirm connectivity.

2.

Enter the

service-module wlan-ap 0 session

control to establish a session into the access point. For instructions, see
“Starting a Wireless Configuration Session” section.

3.

Ping the external server from the access bespeak to ostend connectivity.

The following case shows a sample router and access signal configuration:

Note

If the access betoken enters Bootloader fashion, manually configure the IP address, default router, netmask, and default gateway to upgrade the IOS image.

Note

The IP address must be assigned to the aforementioned subnet equally the VLAN1 interface on the router. Here is an example configuration.

Example

ap: set

CONTROLLER_TYPE=0x05A4

DEFAULT_ROUTER=192.168.10.ane

ENABLE_BREAK=yes

IOS_STATIC_DEFAULT_GATEWAY=192.168.x.ane

IP_ADDR=192.168.10.ii

MANUAL_BOOT=yes

NETMASK=255.255.255.0

PEP_PRODUCT_ID=AP801AGN-A-K9

PRODUCT_MODEL_NUM=AP801AGN-A-K9

TOP_ASSY_SERIAL_NUM=FHKTESTTEST
