Management

Introduction

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
