A source port can be an Ethernet
port, port channel, Fiber Channel port, SAN port channel, VLAN, or a VSAN port.
It cannot be a destination port.
The
following example shows how to configure an Ethernet SPAN source port:
switch# configure terminal
switch(config)# monitor session 2
switch(config-monitor)# source interface ethernet 1/16
switch(config-monitor)#
The following example shows how to configure
a virtual Fibre Channel SPAN source port:
switch# configure terminal
switch(config)# monitor session 2
switch(config-monitor)# source interface vfc 129
switch(config-monitor)#
