I need to know if Service TCP-Keepalives-IN and OUT has any production impact. I am planning to apply this feature for incoming and outgoing TCP connections on my edge routers in a production environment.
As these are the key routers and I am very much concern about the impact of executing these commands.
I hope this makes you feel comfortable deploying the commands!
Here are a couple others I use: no service pad no service finger no ip source-route no ip gratuitous-arps no service dhcp (only on devices that don't offer DHCP relay or addresses) no ip finger no tcp-small-servers (IOS 11.2 and older) no udp-small-servers (IOS 11.2 and older)
