1.4.2 Remote Monitoring (RMON)
The 6E12X-26 and 6E13X-25 supports all Ethernet RMON groups,
which include Statistics, Alarms, Events and History. These groups are
enabled on all ports by default.
Cabletron Systems 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.
1.4.3 Broadcast Suppression
Broadcast Suppression allows 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 up to the set limit. 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.
1.4.4 Port Redirect Function
The port redirect function, also referred to as “Port Mirroring,” is a
troubleshooting tool used to map traffic from a single source port or
multiple source ports to a destination port(s) within the chassis. This
feature functions at the bit level, which allows all packets, 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 is directly connected to
the LAN segment of the source port(s).
