The following example shows how to configure an Ethernet SPAN destination port (HIF):
switch# configure terminal
switch(config)# interface ethernet100/1/24
switch(config-if)# switchport monitor
switch(config-if)# exit
switch(config)# monitor session 1
switch(config-monitor)# destination interface ethernet100/1/24
switch(config-monitor)#
The following example shows how to configure a virtual ethernet (VETH) SPAN destination port:
switch# configure terminal
switch(config)# interface vethernet10
switch(config-if)# switchport monitor
switch(config-if)# exit
switch(config)# monitor session 2
switch(config-monitor)# destination interface vethernet10
switch(config-monitor)#
Configuring Source Ports
Source ports can only be Ethernet ports.
Procedure
PurposeCommand or Action
Enters global configuration mode.switch# configure terminal
Step 1
Enters monitor configuration mode for the specified
monitoring session.
switch(config) # monitor session
session-number
Step 2
Adds an Ethernet SPAN source port and specifies the traffic
direction in which to duplicate packets. You can enter a
switch(config-monitor) # source
interface type slot/port [rx | tx |
both]
Step 3
range of Ethernet, Fibre Channel, or virtual Fibre Channel
ports. You can specify the traffic direction to duplicate as
ingress (Rx), egress (Tx), or both. By default, the direction
is both.
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)#
Configuring Source Port Channels or VLANs
You can configure the source channels for a SPAN session. These ports can be port channels and VLANs.
The monitored direction can be ingress, egress, or both and applies to all physical ports in the group.
