Hi
Thats a good one.So far I have heard only about "IP Routing" is enabled by default which does not reflect in the active running config.It is hard to say that what will be the default service which will be enabled.
Every IOS set has different "default" values.For Eg. a C1721 with 12.2 IP Plus has following :
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
logging queue-limit 100
ip subnet-zero
ip cef
ip audit notify log
ip audit po max-events 100
ip classless
This may vary with a C2600 config 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
boot-start-marker
boot-end-marker
no network-clock-participate slot 1
no network-clock-participate wic 0
no aaa new-model
ip subnet-zero
ip cef
no ftp-server write-enable
control-plane
ip audit notify log
ip audit po max-events 100
But these commands are visible in show running-config. unlike ip routing.You can always negate a running command.
There is no written document about this, hence I am not able to explain more.But above is what I have concluded.Also it will be a great help if you can tell me" what you want to do?"
