Related question: what traffic _is_ getting switched by MSFC? Is this
snmp/routing protocol/netflow export from msfc/cdp/telnet/ssh traffic to or
from MSFC itself or something more? If it is more, than what is it? Is
statement about 7.1 and visibility of MLS/SEF switched traffic on msfc (when
run in hybrid mode) true?

Thanks!
