Assigning a mirror port and monitor ports
6
Configuration guidelines for monitoring traffic
Use the following considerations when configuring mirroring for inbound and outbound traffic:
•
Any port can be mirrored and monitored except for the management port.
•
There can be only one mirror port per packet processor on a 24 X 1G module.
•
For outbound traffic, there can be up to 8 active mirror ports system wide.
Configuring port mirroring and monitoring
You can configure multiple mirror ports on the same module. However, if you mirror inbound traffic
to any of the mirror ports on the module, the traffic is mirrored to all the mirror ports on the
module. If you plan to mirror outbound traffic only, you can use multiple mirror ports on the same
module without the traffic being duplicated on the other mirror ports on the module.
NOTE
You cannot monitor outbound traffic from one armed router traffic.
NOTE
Mirror (analyzer) ports cannot be assigned to the 16x10 card. You can monitor traffic on 16x10
ports.
The following example configures two mirror ports on the same module and one mirror port on
another module. It will illustrate how inbound traffic is mirrored to the two mirror ports on the same
module even if the traffic is configured to be mirrored to only one mirror port on the module.
BigIron RX
(config)# mirror-port ethernet 1/1
BigIron RX
(config)# mirror-port ethernet 1/2
BigIron RX
(config)# mirror-port ethernet 2/1
BigIron RX
(config)# interface ethernet 3/1
BigIron RX
(config-if-e10000-3/1)# monitor ethernet 1/1 both
BigIron RX
(config-if-e10000-3/1)# monitor ethernet 2/1 in
BigIron RX
(config-if-e10000-3/1)# interface ethernet 4/13
BigIron RX
(config-if-e10000-4/1)# monitor ethernet 1/2 both
This example configures two mirror ports 1/1 and 1/2 on the same module. It also configures input
and output traffic from port 3/1 to be mirrored to mirror port 1/1 and input and output traffic from
port 4/1 to be mirrored to mirror port 1/2. Because mirror ports 1/1 and 1/2 are configured on the
same module, mirror port 1/1 will receive the input traffic from port 3/1 as well as port 4/1 and
mirror port 1/2 will receive input traffic from port 4/1 as well as port 3/1 even if they are not
explicitly configured to do so. The outbound traffic from port 3/1 is mirrored to port 1/1 only, as
configured and the outbound traffic from port 4/1 is mirrored to port 1/2 only as configured.
This example also configures one mirror port 2/1 on another module, to which inbound traffic from
port 3/1 is mirrored. Because only one mirror port is configured on this module, the traffic is
mirrored as configured.
If input monitoring is enabled on two ports controlled by the same packet processor, then the input
traffic on these two ports will be mirrored to all the ports configured as mirror ports for these two
monitored ports. This restriction does not apply to outbound monitoring.
