First of all: why do you want

First of all: why do you want to put a port in span mode ? Which is your goal and which ISR router are you using ?

 

Depending on what you want to do and your hardware and IOS release you can proceed in many ways:

  • some ISR support SPAN as far as switch module, for example
    • http://www.cisco.com/c/en/us/td/docs/routers/access/1800/1801/software/configuration/guide/scg/dhcpvlan.html#pgfId-1013148
    • http://www.cisco.com/c/en/us/td/docs/routers/access/interfaces/software/feature/guide/eesm_sw.html#wp1898606
  • if you are using ISO 15.0 or later configure embedded packet capture
    • http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/epc/configuration/15-mt/epc-15-mt-book/nm-packet-capture.html
  • if you need a network analysis tool for a long time, install SRE board with Prime NAM software
  • finally you can connect router to a switch and monitor traffic on the switch

Hello.

I guess feature "IP traffic export" could suit you.

PS: more details - http://www.cisco.com/c/en/us/td/docs/ios/sec_user_services/configuration/guide/12_4/sec_securing_user_services_12-4_book/sec_ip_traff_export.html
