Configuring Mirroring On An Ironstack; Configuration Notes - Dell PowerConnect B-FCXs Configuration Manual

Configuring mirroring on an Ironstack

You can configure mirroring on a Dell IronStack. An IronStack consists of up to 8 PowerConnect
B-Series FCX devices. The stack operates as a chassis. The following examples show how to
configure mirroring for ports that are on different members of a stack, and for ports that are on the
same stack member as the mirror port.

Configuration notes

The following mirroring configuration information applies to PowerConnect B-Series FCX devices
connected in an IronStack topology:

Example 1. Configuring mirroring for ports on different members in an IronStack
In this example, although 2 ports are configured as active ports, only one active mirror port (port
1/1/24) is allowed for the entire stack since the mirror ports and the monitored ports are on
different stack members.
PowerConnect(config)#mirror-port ethernet 1/1/24
PowerConnect(config)#mirror-port ethernet 2/1/24
PowerConnect(config)#interface ethernet 1/1/1
PowerConnect(config-if-e1000-1/1/1)#monitor ethernet 1/1/24 both
PowerConnect(config)#interface ethernet 2/1/1
PowerConnect(config-if-e1000-2/1/1)#monitor ethernet 1/1/24 both
PowerConnect(config)#int ethernet 4/1/1
PowerConnect(config-if-e1000-4/1/1)#monitor ethernet 1/1/24 both
Example 2. Configuring mirroring for ports on the same stack member in an
IronStack
PowerConnect(config)#mirror-port ethernet 1/1/24
PowerConnect(config)#mirror-port ethernet 2/1/24
PowerConnect(config)#mirror-port ethernet 3/1/24
PowerConnect(config)#mirror-port ethernet 4/1/24
PowerConnect(config)#interface ethernet 1/1/1
PowerConnect(config-if-e1000-1/1/1)#monitor ethernet 1/1/24 both
PowerConnect(config)#interface ethernet 2/1/1
PowerConnect(config-if-e1000-2/1/1)#monitor ethernet 2/1/24 both
PowerConnect(config)#int ethernet 4/1/1
PowerConnect(config-if-e1000-4/1/1)#monitor ethernet 4/1/24 both

The input or output mirroring port can be on different ports.
An IronStack can have one mirroring port that monitors multiple ports, but cannot have
multiple mirror ports for one monitored port.
If the mirror port and the monitored ports are on different stack units, only one active mirror
port is allowed for the entire IronStack.
If the mirror port and the monitored ports are on the same port region, multiple active mirror
ports are allowed for the entire IronStack. Devices in an IronStack support 24 ports per port
region.
The maximum number of monitored VLANs on an IronStack is 8.
