• Port-based mirroring
• Address-based mirroring
A sample Port Mirroring Configuration screen accompanies each network
configuration example. Note that the displayed screens do not show all of the
screen prompts that precede some actions.
For example, when you configure a switch for port mirroring or when you modify
an existing port mirroring configuration, the new configuration does not take
effect until you respond [Yes] to the following screen prompt:
Port-based mirroring configuration
Figure 46 shows an example of a port-based mirroring configuration where port
23 is designated as the monitor port for ports 24 and 25 of Switch S1. Although
this example shows ports 24 and 25 monitored by the monitor port (port 23), any
of the trunk members of T1 and T2 can also be monitored.
In this example, Figure 46 shows port X and port Y as members of Trunk T1 and
Trunk T2. Port X and port Y are not required to always be members of Trunk T1
and Trunk T2.
Figure 46 shows the Port Mirroring Configuration screen setup for this example.
Note: Trunks cannot be monitored and trunk members cannot be
configured as monitor ports (see “MultiLink Trunking configuration
rules ”).
Is your port mirroring configuration complete? [ Yes ]
