Important Considerations
■On CoreBuilder® 3500 and CoreBuilder 9000 syst ems, you can
connect as many as 16 network analyzers to a system. On other
platforms, you can connect one network analyzer. 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 oth er data. Instead, it re ceives only the data fro m the
ports to be monitored. If you have enabled the Spanning Tree Protocol
(STP) on the port, STP is automatically disabled.
■If the physical port configuration changes in the system (tha t is, if you
remove or rearrange modules), the MAC address of the analyzer port
remains fixed. If you replace the module with the analyzer port with a
module of a different media type, the roving analysis port ( RAP)
configuration for that port is cleared.
■When you configure a port that is part of a virtual LAN (VLAN) as an
analyzer port, a warning is displayed b ecause 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 1 00 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 system displays the MAC
address of the analyzer port. Record this information for setting u p the
port that you want to monitor.
■On the CoreBuilder 9000, the port to which the analyzer is attached
and the port you wish to monitor must be on the same blade.
■Trunked ports and resilient link ports can not be configured as analyzer
ports.
