Parameter Description
Port
Displays the port from which packet samples are being extracted.
Analyzer Server ID
Displays the ID of the Analyzer Server where datagrams, containing the packet sampling
information taken using this sampling mechanism, will be sent.
Configured Rate
Displays the configured rate of packet sampling for this port based on a multiple of 256. For
example, if a figure of 20 is in this field, the switch will sample one out of every 5120 packets
(20 x 256 = 5120) that pass through the individual port.
Active Rate
Displays the current rate op packet sampling being performed by the Switch for this port,
based on a multiple of 256. For example, if a figure of 20 is in this field, the switch will sample
one out of every 5120 packets (20 x 256 = 5120) that pass through the individual port.
Max Header Size
Displays the number of leading bytes of the sampled packet header. This sampled header will
be encapsulated with the datagram to be forwarded to the Analyzer Server.
