Enterasys Networks 6H302-48 manual Remote Monitoring Rmon, Broadcast Suppression

Remote Monitoring (RMON)

SmartTrunk, also referred to as SmartTrunking, is Enterasys Networks’ terminology for load balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to provide additional throughput. The SmartTrunk application can be used with any of Enterasys Networks’ switch modules (except ATM modules).

For more information about SmartTrunk and how to configure the module, refer to the Matrix E7 Series and SmartSwitch 6000 Series Local Management User’s Guide.

1.5REMOTE MONITORING (RMON)

The module supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and History groups are enabled on all ports by default.

Enterasys Networks RMON Actions is a vendor-specific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast threshold is crossed.

1.6BROADCAST SUPPRESSION

Broadcast Suppression enables a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out the other ports on the module. Any broadcast frames above this specified limit are dropped. In the event that broadcast frames are being suppressed, multicast and unicast frames continue to be switched.

1.7PORT/VLAN REDIRECT FUNCTIONS

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map traffic from a single source port to a single destination port within the module. This feature allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe. The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment of the source port.
