Group Policies

Security Configuration Policies

 

Special multicast routers/queriers communicate by using three message

 

types - query, report, and leave group. The query message, sent by a querier,

 

is used to discover which network interfaces belong to a multicast group. Each

 

host responds to the query message with a report message that tells the querier

 

the host is a member of the multicast group. The host also can send a report

 

message to join a group or a leave message to leave a group.

 

 

N o t e

Using the console you can designate specific ports to always or never forward

 

multicast packets.

Forward with High Priority

When Forward with High Priority is checked, any IGMP packets received by the switch will be forwarded in a prioritized manner, preceding packets with normal priority.

The Spanning Tree Protocol

The Spanning Tree Protocol (IEEE 802.1d) maintains a loop-free topology in networks with redundant bridges or switches. The spanning tree devices determine which devices will be active and which will be backups so that no two nodes in a network have more than one active path between them at any time. The Spanning Tree Protocol uses the most efficient path between segments. If a bridge or switch fails, the other bridges and switches reconfigure the network automatically. When the problem is repaired, the bridges and switches automatically return to the original network configuration.

Security Configuration Policies

To configure Security policies for a group, click on the Security button in the Configuration Policies main page. The Security Policies page for that group displays.

Communities

You can create up to five communities for each group. The default community is “public”.

Do not delete the “public” community.
