 B<ciscodump> is an extcap tool that relys on Cisco EPC to allow a user to run a remote capture
 on a Cisco router in a SSH connection. The minimum IOS version supporting this feature is 12.4(20)T. More details can be

-The remote filter on the router. This is a capture filter that follows the Cisco IOS standards (http://www.cisco.com/c/en/us/support/docs/ip/access-lists/26448-ACLsamples.html). Multiple filters can be specified using a comma between them. BEWARE: when using a filter, the default behavior is to drop all the packets except the ones that fall into the filter.
