Cisco Cisco IOS Software Release 12.2(8)YJ Release Notes

The following sections contain important notes about Cisco IOS Release 12.2(8)YJ1 that can apply to 
SOHO 70 and Cisco 800 series routers. (Also, see the 

In Cisco 800 series routers, the Ethernet 0 LAN interface defaults to the primary IP address of 10.10.10.0 
in a private network. If you need to change this IP address to match the local network configuration, you 
can use the command ip address or the Cisco Router Web Setup (CRWS) web interface. 

Using the CRWS interface to change the IP address preserves the existing IP address as the primary 
address of the interface and assigns the new IP address as the secondary address on the interface. This 
CRWS interface functionality maintains (does not break) the existing connection between the PC web 
browser and the Cisco 800 series router and thereby does not interfere with normal router operations for 
most configurations.

Because of this behavior, the Cisco Easy VPN client feature assumes that if a secondary IP address exists 
on the Ethernet 0 interface, the secondary address should be used as the IP address for the inside interface 
for the NAT/PAT configuration. If no secondary address exists, the primary IP address will be used for 
the inside interface address, as is normally done on other platforms. If this behavior is not desired, use 
the ip address CLI command instead of the CRWS web interface to change the interface address.

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most 
serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these 
three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS Release 12.2(8)YJ1. For 
information on caveats in Cisco IOS Release 12.2, see

 Caveats for Cisco IOS Release 12.2

. For 

information on caveats in Cisco IOS Release 12.2 T, see 

. These 

two documents list severity 1 and 2 caveats and are located on 

CCO

and the Documentation CD-ROM.

This section describes unexpected behavior in Release 12.2(8)YJ1.

When acting as a PPPoE client, the Cisco 806 router a crashes after the DDR idle timeout expires. This 
problem might be seen only in lab scenarios.
