Cabletron Systems 2208 manual Local Management, Broadcast Suppression

Chapter 1: Introduction

1.4LOCAL MANAGEMENT

Management of the 2H22-08R is accomplished using Local Management tools or remote Simple Network Management Protocol (SNMP) management stations. Out-of-band Local Management is accessible through the RS232 COM port on the front panel using a VT100 terminal, or a remote VT100 terminal emulator via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management provides the tools to manage the 2H22-08R, and its two Fast Ethernet Interface Modules. It also allows the following tasks to be performed:

•Assign an IP address and subnet mask to the 2H22-08R.

•Select a default gateway and default interface.

•Control local and remote access.

•Designate workstations to receive SNMP traps from the 2H22-08R.

Chapter 5 provides detailed information about Local Management of the 2H22-08R, and its two optional Fast Ethernet Interface Modules. Local Management also provides the features detailed in Section 1.4.1 through Section 1.4.4.

1.4.1Broadcast Suppression

Broadcast Suppression allows a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out of 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 without suppression.
