Cisco Cisco IOS Software Release 12.2(2)XK Notas de publicación

The following sections describes the new features supported by the Cisco 806 router for 
Release 12.2(2)XK and above.

The Cisco 806 router connects corporate telecommuters and small offices to corporate LANs and the 
Internet through Internet Service Providers (ISPs), using a broadband or Ethernet connection. The router 
provides bridging and multiprotocol routing between LAN and WAN ports.

The following sections list the new software features supported by Cisco IOS Release 12.2(2)XK on the 
Cisco 806 router.

Release 12.2(2)XK supports committed access rate (CAR) on Cisco 806 routers, to limit bandwidth 
transmission rates to traffic sources and destinations. The CAR feature also specifies policies for 
handling traffic that breaches the specified bandwidth allocations. To enable CAR, enter the command 
rate-limit in ATM-interface-configuration mode. Additional feature configuration instructions and 
examples are available in the 

publication.

Prior to Release 12.1(5), DHCP options on the IOS DHCP server could only be configured through the 
command-line interface (CLI). You can now configure the same DHCP options on multiple DHCP 
servers by configuring one remote master DHCP server located on the corporate backbone. Using this 
capability causes all local DHCP servers to have the same DHCP options as those on the remote 
DHCP server. 

To enable this feature, the Cisco IOS DHCP server allows configuration information to be updated 
automatically by PPP. You can enable PPP to automatically configure the Domain Name Server (DNS), 
the Windows Information Name Server (WINS), or the NetBIOS Name Service (NBNS), and the server
