Cisco Cisco IOS Software Release 12.2(58)SE

Download the image file from the TFTP server to the switch. If you are installing the same version of 
software that is currently on the switch, overwrite the current image by entering this privileged EXEC 
command:

Switch# archive download-sw /overwrite /reload 

[[//location]/directory]/image-name.tar

The /overwrite option overwrites the software image in flash memory with the downloaded one. 

The /reload option reloads the system after downloading the image unless the configuration has been 
changed and not saved.

For //location, specify the IP address of the TFTP server.

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory 
and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite 
the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/image-name.tar

You can also download the image file from the TFTP server to the switch and keep the current image by 
replacing the /overwrite option with the /leave-old-sw option.

For additional recovery procedures, see the “Troubleshooting” chapter in the software configuration 
guide for this release.

You can assign IP information to your switch by using these methods:

The Express Setup program, as described in the switch getting started guide.

The CLI-based setup program, as described in the switch hardware installation guide.

The DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigning an IP address, as described in the switch software configuration guide.

Protocol storm protection to control the rate of incoming protocol traffic to a switch by dropping 
packets that exceed a specified ingress rate. 

VACL Logging to generate syslog messages for ACL denied IP packets. 

Memory consistency check routine enhancements to detect and correct invalid ternary content 
addressable memory (TCAM) table entries that can affect switch performance. 

Call Home to provide e-mail-based and web-based notification of critical system events. Users with 
a service contract directly with Cisco Systems can register Call Home devices for the Cisco Smart 
Call Home service that generates automatic service requests with the Cisco TAC.
