The following fields are displayed:
Parameter
Description
Status
This displays
Powered
if the corresponding Redundant Power Supply
(RPS) is powering the switch.
Output Voltage
This displays
Normal
if the power supply is operating properly.
If one of the
RPSs is not functioning normally, a beep will sound from the switch, and
Not
Normal
will be displayed.
Fan1
This displays the status of the first of the two fans that cool the Redundant
Power Supply (RPS).
Fan2
This displays the status of the second of the two fans that cool the
Redundant Power Supply (RPS).
System Fan
This displays the operating status of the four internal fans that cool modules
installed in the DES-6500.
MAC Address
This allows the switch’s dynamic MAC address forwarding table to be viewed. When the
switch learns an association between a MAC address and a port number, it makes an entry
into its forwarding table. These entries are then used to forward packets through the switch.
To view the
MAC Address
forwarding table, from the
Monitoring
menu, click the

IGMP Snooping Table
IGMP Snooping allows the switch to read the Multicast Group IP address and the
corresponding MAC address from IGMP packets that pass through the switch. The number of
IGMP reports that were snooped is displayed in the
Reports
field.
To view the
IGMP Snooping
table, click
IGMP Snooping Group
on the
Monitoring
menu:
Figure 6- 18. IGMP Snooping Table
The following fields are displayed:
Parameter
Description
VLAN ID
The VLAN ID (VID) of the multicast group.
Multicast Group
The IP address of the multicast group.
MAC Address
The MAC address of the multicast group.
Queries
A read only field showing the status of the Querier State. Disabled implies
that the Switch is not transmitting IGMP Snooping Query packets, while
Enabled means those packets are being transmitted.
Reports
The total number of reports received for this group.
Note
: To configure IGMP snooping for the DES-6500, go to
the Configuration folder and select IGMP. Configuration and
other information concerning IGMP snooping may be found in
Section 4 of this manual under Configuring IGMP.
