Configuring SPAN
The following example shows configuring an Ethernet SPAN destination port:
switch# configure terminal
switch(config)# interface fc 2/4
switch(config-if)# switchport mode SD
switch(config-if)# switchport speed 1000
switch(config-if)# exit
switch(config)# monitor session 2
switch(config-monitor)# destination interface fc 2/4
Configuring Source Ports
You can configure the source ports for a SPAN session. The source ports can be Ethernet, Fibre Channel,
or virtual Fibre Channel ports.
To configure the source ports for a SPAN session, perform this task:
The following example shows configuring an Ethernet SPAN source port:
switch# configure terminal
switch(config)# monitor session 2
switch(config-monitor)# source interface ethernet 1/16
The following example shows configuring a Fibre Channel SPAN source port:
...
switch(config-monitor)# source interface fc 2/1
The following example shows configuring a virtual Fibre Channel SPAN source port:
...
switch(config-monitor)# source interface vfc 129
Configuring Source Port Channels, VLANs, or VSANs
You can configure the source channels for a SPAN session. These ports can be port channels, SAN port
channels, VLANs, and VSANs. The monitored direction can only be ingress and applies to all physical
ports in the group.
