hi bapat,

traceroute in cisco switch/routers.

From windows, Cisco or Linux machine for entering interface you can use tracert(trace) or pathping (on Windows)

tracert target_IP

pathping target_IP

For exit interface its more difficult you can use ping with record route option (on Windows)h

ping -n 1 -r 9 target_IP

n means number of packets, r means record route option , 9 is maximum number for record route...

Record-route uses Option field in IP packet header to record outgoing router interface. Record-route has limited value because space allocated for optios in IP header is only 9..

Also traffic for record route must be permited

ACL should looks like this

permit ip any any option record-route

Hope that helps rate if it does
