Dave,
One way of letting you know what type of traffic is going through
your router is to define access-list on your interfaces and send all
your syslogging to an external system for real-time or later viewing.
You would have to log all lines of the access-list to capture what
traffic is trying to come and go. This will not actually capture the
traffic itself, but will allow you to see what type of IP traffic is
flowing across the router. Don't know if this is remotely what you
are looking for, but works well for identifying who and what type of
traffic is banging on you. (Also, these can cause some latency
through the router if you run massive access-list)

Subject: Re: capturing traffic on cisco routers
Hello Dave
You can configure one of the ports of your router to send a copy of
all the
traffic that it receives on that port to another port, where you
connect a
PC with a packet sniffer. Depending on your speed you would like
eather to
analyse packets on the fly or to save them for later analyse.
