Management
Management of the 9E531-24 module and SmartSwitch chassis and any optional
equipment is accomplished using the Local Management application or remote
SNMP management stations. Local Management is accessible through the RS232
COM port on the Environmental Module using a local VT100 terminal, or a
remote VT100 terminal via a modem connection, and in-band via a Telnet
connection. In-band remote management is possible through Webview or any
SNMP compliant Network Management Software.
Local Management provides the ability to manage the 9E531-24. Local
Management information for non-Ethernet HSIMs or VHSIMs is included in their
respective user’s guide. For details on how to get manuals, refer to the Related
Manuals section in the Introduction.
WebView
The 9E531-24 modules can be managed by Cabletron WebView, a browser-based
utility. There is no software to install as this management capability is built into
each module.
Remote Monitoring (RMON)
The 9E531-24 supports all nine Ethernet RMON groups. The Statistics, Alarms,
Events and History 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 setting an 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.
Broadcast 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 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.
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 to a destination
port within the chassis. This feature 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.
Flow Control
Flow Control is a method of managing the flow of frames between two devices. It
ensures that a transmitting device does not overwhelm a receiving device with
data. This enables the receiving device to communicate with the transmitting
