Monitoring and Analyzing Switch Operation
Traffic Mirroring
The following commands are not supported:
monitor mac 111111-222222 src mirror 3
monitor mac 111111-222222 dest mirror 4
In addition, if you enter the monitor mac 111111-222222 both mirror 1 com-
mand, you cannot use the MAC address 111111-222222 in any other monitor
mac mirror configuration commands on the switch.
■ To re-use a MAC address that has already been configured as a source
and/or destination address for traffic selection in a mirror session, you
must first remove the configuration by entering the no form of the com-
mand, and then re-enter the MAC address in a new monitor mac mirror
command.
For example, if you have already configured MAC address 111111-222222
to filter inbound and outbound mirrored traffic, and decide to use it to
filter only inbound traffic in a mirror session, you could enter the follow-
ing commands:
monitor mac 111111-222222 both mirror 1
no monitor mac 111111-222222 both mirror 1
monitor mac 111111-222222 src mirror 1
■ A mirroring session in which you configure MAC-based mirroring is not
supported on a port, trunk, mesh or VLAN interface on which a mirroring
session with a classifier-based mirroring policy is configured.
Selecting Inbound Traffic Using Advanced
Classifier-Based Mirroring
In software release K.14.01 or greater, in addition to the traffic selection
options described in “4. Configure the Monitored Traffic in a Mirror Session”
on page B-55, traffic mirroring supports the use of advanced classifier-based
functions that provide:
■ A finer granularity for selecting the inbound IP traffic that you want to
mirror on an individual port or VLAN interface (instead of mirroring all
inbound traffic on the interface)
■ Support for mirroring both IPv4 and IPv6 traffic
■ The ability to re-use the same traffic classes in different software-feature
configurations; for example, you can apply both a QoS rate-limiting and
mirroring policy on the same class of traffic.
