PurposeCommand or Action
To enable the virtual ethernet port
as destination interface in the
monitor configuration, you can use
the destination interface vethernet
slot/port command.
Note
Example
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
switch(config-monitor) # source interface type
slot/port [rx | tx | both]
Step 3
duplicate packets. You can enter a 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.
