The administrator can configure the user on a switch port (GE/LAG port) belonging to which
multicast group and restrict the number of multicast group that the user on the switch can
join. Then the administrator is able to control the network service (e.g, IP/TV service) that
the user can enjoy.
The Throttling page is used for configuring the maximum number (0~255) of IGMP group that a
user on a switch port can join
. After defined the maximum number, each switch port
interface can be set to deny the IGMP join report or set to replace randomly selected
multicast interface with received IGMP join report.
Available settings are explained as follows:
Item Description
Ports Use the drop down list to specify LAN Port (GE/LAG).
Max Group Define the maximum number of IGMP group profile that a user
on the switch can join. If “0” is selected, then such interface
(port) can join all of the IGMP group profiles (defined in
Filtering Profile).
Exceed Action VigorSwitch will perform the action defined below when the
number of IGMP join report for the specified interface exceeds
value defined in Max Group.
Deny – It is default setting. The IGMP join report (for multicast
service) received by such interface will be discarded.
Replace – When it is selected, a new group with IGMP report
received will replace the existing group.
Apply Apply the settings to the switch.
Edit
- Click it to modify port setting (max group and exceed
action).
