SMON
SMON Overview
SMON is Avaya’s standard-setting switch monitoring technology that has now
been adopted as IETF standard RFC 2613. SMON extends the RMON standard to
provide the switch monitoring tools and features you need to analyze the switched
network and all its components.
SMON provides the basis for top-down network monitoring. Top-down monitoring
starts when the you notice particular traffic flow patterns in a global view of the
network. The network manager can progressively focus in and find the specific
source or sources of the traffic.
Using this method, the amount of information the network manager must assess is
kept to a minimum. Top-down monitoring is robust enough to enable control of
even the most complex and sophisticated networks.
SMON is an extension of the RMON standard. SMON adds to the monitoring
capabilities of RMON in the following ways:
• It provides additional tools and features for monitoring in the switch
environment.
• It allows monitoring of ATM networks that are based on cells rather than
packets.
• It provides a global view of traffic flow on a network with multiple switches.
SMON monitoring provides:
• A global view of traffic for all switches on the network
• An overall view of traffic passing through a specific switch
• Detailed data of the hosts transmitting packets or cells through a switch
• An analysis of traffic passing through each port connected to a switch, and
• A view of traffic between various hosts connected to a switch.
SMON extends both RMON I for the MAC layer, and RMON 2 for the network
layer and higher. SMON monitoring collects and displays data in real-time.
Top-down view of all traffic:
• Network view for selected switches
• Network view for selected ports
•VLAN view
•History
L In order to use SMON, you need to install the SMON license on the P330 switch
and use Avaya MSNM with SMON. See “Basic Switch Configuration“ in the
Avaya P330 Installation and Maintenance Guide.
L SMON for the network layer is not supported in this version of the P330.
