Chapter 8 Advanced Configuration for Compex CGX3224
44
Hello Time
(from 1 to 10s)
Determines how often the switch broadcasts hello
messages to other switches.
Forward Delay
Determines how long each of the listening and
learning states last before the interface begins
forwarding. This wait is necessary so that other
switches on the network ensure no loop is formed
before they allow the port to forward packets.
Max Age
Determines the amount of time the switch stores
protocol information received on an interface.
Procedures
1. Select Spanning Tree state option and set Root Priority from 0 - 65535
s, and Hello Time from 1 - 10 s.
2. Key in the Forward Delay Time, Maximum Age and Hold Time.
3. Click Apply and Save button to update your configuration.
NOTE
The screen is divided into two sections. Current Spanning Tree Root section
displays the read-only Spanning Tree settings for the current root switch and the
parameters this switch is to use when it becomes the root switch only when you
click on Apply button.
8.2 IGMP Configuration
Internet Group Management Protocol (IGMP) is an Internet protocol that provides a
way for an Internet computer to report its
multicast group membership to adjacent
routers. It allows Compex CGX3224 to forward multicast traffic intelligently. The
switch "snoops" the IGMP query and report messages and forwards traffic to only the
ports that request the multicast traffic. This prevents the switch from broadcasting the
traffic to all ports and possibly affecting network performance.
