Various cisco platforms have built-in service names. The
list varies from platform to platform and over software releases.
Unless I miss something, there's no way to add or remove
service names. Also there is no way to tell a "show access list"
or "show run" command to use port numbers instead of service
These service names are not unified with the PAM, either.
It makes migrations a total pain.
So either allow config directives to put in missing service names
a-la PAM, or an editable /etc/services type file, or put a flag on the
show run command to get rid of service and hostnames a-la
the ASA's "no names" mode for hostnames.
