SMC Networks SMC6724L3 manual System Defaults, Function Parameter Default

INTRODUCTION

Multicast Filtering – Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and Query at Layer 2 and IGMP at Layer 3 to manage multicast group registration.

Multicast Routing – Routing for multicast packets is supported by the Distance Vector Multicast Routing Protocol (DVMRP) and Protocol-Independent Multicasting - Dense Mode (PIM-DM). These protocols work in conjunction with IGMP to filter and route multicast traffic. DVMRP is a more comprehensive implementation that maintains its own routing table, but is gradually being replacing by most network managers with PIM, Dense Mode and Sparse Mode. PIM is a very simple protocol that uses the routing table of the unicast routing protocol enabled on an interface. Dense Mode is designed for areas where the probability of multicast clients is relatively high, and the overhead of frequent flooding is justified. While Sparse mode is designed for network areas, such as the Wide Area Network, where the probability of multicast clients is low. This switch currently supports DVMRP and PIM-DM.

System Defaults

The switch’s system defaults are provided in the configuration file “Factory_Default_Config.cfg.” To reset the switch defaults, this file should be set as the startup configuration file (page 3-24).

The following table lists some of the basic system defaults.

Function	Parameter	Default
Console Port	Baud Rate	9600
Connection
	Data bits	8
	Stop bits	1
	Parity	none
	Local Console Timeout	0 (disabled)
