Details on the bandwidth requirements
The recommended bandwidth described above is a conservative figure that is meant to
ensure that the performance of 5620 SAM and its ability to manage successfully each
network element will not be affected by unusual network conditions.
Specifically, the bandwidth recommendation ensures that 5620 SAM can fully discover
(or resynchronize) all of the objects contained in the network element, within a reasonable
amount of time, usually no more than a few minutes for a densely populated network
element.
The following are the main operations that result in significant amounts of information
being exchanged between 5620 SAM and the network elements. These factors are
therefore the principal contributors to the bandwidth requirements.
•
Network Element Discovery: Upon first discovery of the network element, a
significant amount of data is exchanged between 5620 SAM and the network element.
•
SNMP traps: SNMP traps do not result directly in significant data being sent from the
network element to the 5620 SAM. Several of the SNMP traps however do not
contain all of the information required for 5620 SAM to completely represent the new
status of the network element. As a result, 5620 SAM will subsequently perform a
poll of a certain number of the SNMP MIBs to obtain the required information from
