Important Considerations
The port to which the analyzer is attached and the port you wish to
monitor must be on the same module.
You can connect up to 16 network analyzers. For more accurate
analysis, attach the analyzer to a dedicated port instead of through a
repeater.
After a port is selected to serve as an analyzer port, it cannot receive
or transmit any other data. Instead, it receives only the data from the
ports to be monitored. If you have enabled the Spanning Tree Protocol
(STP) on the port, STP is automatically disabled.
When you configure a port that is part of a virtual LAN (VLAN) as an
analyzer port, a warning is displayed because adding the port removes
the port from all VLANs. When the port is restored (when you remove
the analyzer port), it becomes a member of the default VLAN.
If the probe is attached to a 10 Mbps Ethernet analyzer port and the
roving analysis port (RAP) is monitoring a 100 Mbps Ethernet port
with a sustained traffic rate greater than 10 Mbps, the analyzer may
not see all of the frames.
After you enter a bridge port number, the module displays the MAC
address of the analyzer port. Record this information for setting up the
port that you want to monitor.
Trunked ports and resilient link ports can not be configured as analyzer
ports.
