boot configuration file (by using the command delete file), without first setting

 

 

 

 

 

 

 

 

 

 

 

 

 

 

a new preferred release or boot configuration file. Therefore, it was possible to

 

 

 

 

 

 

 

 

 

 

 

 

CR00013683

 

 

accidentally delete these files, which caused network disruptions if the router or

 

 

 

 

 

 

 

 

 

 

 

 

 

 

switch restarted. If the router or switch restarted after the user had deleted the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

preferred release, it booted from the default software. Similarly, if the router or

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

switch restarted after the user had deleted the current boot configuration file, it

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

started up with no configuration.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This enhancement ensures that users can no longer delete the preferred software

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

release or the current boot configuration file. If you want to delete the files

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

without specifying new preferred files, first use the commands delete

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

install=pref or set config=none to stop the files from being preferred.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note that this enhancement does not apply to routers or switches that are

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

manufactured for the Japanese market. Japanese users can still delete the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

preferred software release and the current boot configuration file.

netmask. This results in a slightly non-standard subnet that has no network

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

address or broadcast address. This has become a popular extension to IP, because

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

it reduces wastage of IP addresses on point-to-point links.

policy has been increased from 40 to 100, so that IPsec can now support up to

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

100 concurrent roaming Microsoft Windows hosts.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Site-to-site VPN connections are not usually limited by the number of SA bundles

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

per policy, because different IPsec policies with different traffic selectors can be

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

configured to support more IPsec VPN connections. However, the number of SA

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

bundles per policy did limit configurations that support roaming Windows

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

laptops (IPsec transport mode connections over L2TP), because the only traffic

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

selectors known ahead of time are lport=1701 and transportprotocol=udp.
