Query Response Interval
: Enter the response interval time (sec).
Last Member Query Interval
: Enter the interval time (sec) the multicast router query the specified
group after it has received leave message.
Robustness Value
: Enter the router robustness parameter, 2-7, the greater the robustness value, the
more robust the Querier is.
Maximum Multicast Groups
: Enter the Maximum Multicast Groups.
Maximum Multicast Data Sources (for IGMP v3):
Enter the Maximum Multicast Data Sources,1- 24.
Maximum Multicast Group Members
: Enter the Maximum Multicast Group Members.
Fast leave:
Check to determine whether to support fast leave. If this value is enabled, IGMP proxy
removes the membership of a group member immediately without sending an IGMP membership
query on downstream. This is very helpful if user wants fast channel (group change) changing in cases
like IPTV environment.
LAN to LAN (Intra LAN) Multicast:
Check to determine whether to support LAN to LAN (Intra LAN)
Multicast. If user want to have a multicast data source on LAN side and he want to get IGMP snooping
enabled, then this LAN-to-LAN multicast feature should be enabled.
Membership Join Immediate (IPTV):
When a host joins a multicast session, it sends unsolicited join
report to its upstream router immediately. The Startup Query Interval has been set to 1/4 of the
General Query value to enable the faster join at startup.
MLD
Default Version
: Enter the supported MLD version, 1-2, default is MLDv2.
Query Interval
: Enter the periodic query interval time (sec) the multicast router sending the query
message to hosts to understand the group membership information.
Query Response Interval: Enter the response interval time (sec).
Last Member Query Interval: Enter the interval time (sec) the multicast router query the specified
group after it has received leave message.
Robustness Value
: Enter the router robustness parameter, default is 2, the greater the robustness
value, the more robust the Querier is.
Maximum Multicast Groups
: Enter the Maximum Multicast Groups.
Maximum Multicast Data Sources(for MLDv2
): Enter the Maximum Multicast Data Sources,1-24.
Maximum Multicast Group Members
: Enter the Maximum Multicast Group Members.
Fast leave
: Check to determine whether to support fast leave. If this value is enabled, MLD proxy
removes the membership of a group member immediately without sending an MLD membership query
on downstream. This is very helpful if user wants fast channel (group change) changing in cases like
IPTV environment.
LAN to LAN (Intra LAN) Multicast
: Check to determine whether to support LAN to LAN (Intra LAN)
Multicast. If user want to have a multicast data source on LAN side and he want to get MLD snooping
enabled, then this LAN-to-LAN multicast feature should be enabled.
Management
SNMP Agent
SNMP, Simple Network Management Protocol, is the most popular one in network. It consists of
SNMP Manager
,
SNMP Agent and MIB. Every network device supporting SNMP will have a SNMP
Agent which is a management software running in the device.
SNMP Manager, the management software running on the server, it uses SNMP protocol to send
GetRequest
、
GetNextRequest, SetRequest message to Agent to view and change the information of
the device.
SNMP Agents, the management software running in the device, accepts the message from the
manager, Reads or Writes the management variable in MIB accordingly and then generates Response
message to send it to the manager. Also, agent will send Trap message to the manager when agent
finds some exceptions.
