Configure Switch C:

# Create a local mirroring group.

<3Com> system-view

[3Com] mirroring-group 1 local 

# Configure the source ports and destination port for the local mirroring group.

[3Com] mirroring-group 1 mirroring-port Ethernet 1/0/1 Ethernet 1/0/2 both

[3Com] mirroring-group 1 monitor-port Ethernet 1/0/3 

#

mirroring-group 1 local

#

interface Ethernet1/0/1

mirroring-group 1 mirroring-port both

#

interface Ethernet1/0/2

mirroring-group 1 mirroring-port both

#

interface Ethernet1/0/3

mirroring-group 1 monitor-port

# 

When configuring local port mirroring, note the following:

■

Packets sent from the switch CPU cannot be mirrored.

■

Packets received on the destination port are those processed and forwarded by 
the switch.

■

The local mirroring group takes effect only after a source port and a destination 
port are added to it.

■

The source port or destination port to be configured cannot be a fabric port 
(only the Switch 5500/5500G have this limitation), or a member port of an 
existing mirroring group; besides, a destination port cannot be a member port 
of an aggregation group, an LACP-enabled port, or an STP enabled port.

■

When you configure a mirroring destination port on the Switch 5500, if 
mirroring group 1 does not exist on the switch, the switch will automatically 
create local mirroring group 1 and add the destination port to the group; if 
port mirroring group 1 already exists but is not a local mirroring group, your 
configuration of the destination port will fail.

■

On a Switch 4500, if you execute the monitor-port command on different 
ports to configure the mirroring destination port for the switch, the last 
configuration takes effect.
