I have one branches that connected to my HQ, using lease line. the ETH 0 interface at router at HQ side is physically connected to port 8/19 on my cisco catalyst. I connecting another port 6/33 to my network sniffer. i did a span command as below :
span 8/19 6/33
Destination : Port 6/33
Admin Source : Port 8/19
Oper Source : Port 8/19
Direction : transmit/receive
Incoming Packets: disabled
Learning : enabled
Multicast : enabled
Filter : -
Status : active
I expected i can view all ip address that go through the link at port 8/19. but it seems like it only shows the IP from the same VLan (same subnet). where did i do wrong according to scenario above?
