It's hidden, and you have to configure "service internal" in orderto bring it into existence. I.e.

as5300-1(config)#service internalas5300-1(config)#no ip cache-invalidate-delay

It's generally recommended for systems running 12.0T/12.1 code ifthey have lots of interfaces (>300) and are not doing CEF.

[...]

"ip route profile" was implemented way back in late '96 by CSCdi76662.However we have historically refrained from documenting this (CSCdk01634,CSCdz19775) as this has been declared to be a hidden command that "shouldnot be used by customers".However, in fact this is NOT a hidden command ... so I've just nowgone ahead and reopened CSCdz19775.

Introduction

The Route Table Profiling feature was developed to assist network engineersin monitoring routing table fluctuations, which may be the result of routeflapping, network failure, or network service restoration. This feature wasadded in CSCdi76662 to the 11.1CC train of Cisco IOS.

The Route Table Profiling feature is an undocumented and unsupportedfeature. There is no MIB support provided.

ConfigurationThe Route Table Profiling feature is enabled globally. The command is "iproute profile" in global configuration mode. This feature can be disabledwith the command "no ip route profile" in global configuration mode.Routing table change statistics can be viewed with the "show iproute profile" command in exec mode.

I assume you have preauthentication already configured? By default, wesend Service-Type = Outbound-User. In 12.1(4)T and later, you canconfigure the (hidden) command "radius send service-type call-check"to change the value from Outbound-User to Call-Check. I submittedCSCdt85947 to get the command unhidden and documented. Here is therelease-note I attached:

The command "radius send service-type call-check" is hidden. Thiscommand is available in 12.1(4)T and later and is used to change thevalue of the Service-Type RADIUS attribute the access server sendswhen doing pre-authentication. The default is to send Outbound-User(5). With this command configured, we will send Call-Check (10). Thisis useful in a multi-vendor environment as well as when migrating anexisting RADIUS database for use withe Cisco access server.
