Today, I need to upgrade a WLC 5508 and 4402 from 6.0.199.4 and 6.0.188.0. to 7.0.240.0. On Thursday, I will upgrade a 3750G with WLC module to 7.0.240.0.
To reduce the down time of the AP, predownload image of AP is used. Only 25 AP can be predownload at the same time =.=

SSH configuration
Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices.
The Cisco IOS image used must be a k9(crypto) image in order to support SSH. For example c3750e-universalk9-tar.122-35.SE5.tar is a k9 (crypto) image.

Set Up an IOS Router or Switch as SSH Client
There are four steps required to enable SSH support on a Cisco IOS router:
- Configure the hostname command.
- Configure the DNS domain.
- Generate the SSH key to be used.
- Enable SSH transport support for the virtual type terminal (vtys).
