DES-30XX Layer 2 Switch CLI Reference Manual
fast leave function. Enabled, this function will allow members of a multicast
group to leave the group immediately (without the implementation of the
Last Member Query Timer) when an IGMP Leave Report Packet is received
by the Switch.
Only administrator-level users can issue this command.
Used to configure the time in seconds between general query
transmissions, the maximum time in seconds to wait for reports from
members and the permitted packet loss that guarantees IGMP snooping.
config igmp_snooping querier [vlan_name <vlan_name 32> | all]
{query_interval <sec 1-65535> | max_response_time <sec 1-25> |
robustness_variable <value 1-255> | last_member_query_interval <sec
1-25> | state [enable | disable]}
This command configures IGMP snooping querier.
vlan_name <vlan_name 32> − The name of the VLAN for which IGMP
snooping querier is to be configured.
all – Selecting this parameter will configure IGMP for all VLANs on the
Switch.
query_interval <sec 1-65535> − Specifies the amount of time in seconds
between general query transmissions. The default setting is 125 seconds.
max_response_time <sec 1-25> − Specifies the maximum time in seconds
to wait for reports from members. The default setting is 10 seconds.
robustness_variable <value 1-255> − Provides fine-tuning to allow for
expected packet loss on a subnet. The value of the robustness variable is
used in calculating the following IGMP message intervals:
•
Group member interval—Amount of time that must pass before a
multicast router decides there are no more members of a group on
a network. This interval is calculated as follows: (robustness
variable x query interval) + (1 x query response interval).
•
Other querier present interval—Amount of time that must pass
before a multicast router decides that there is no longer another
multicast router that is the querier. This interval is calculated as
follows: (robustness variable x query interval) + (0.5 x query
response interval).
•
Last member query count—Number of group-specific queries sent
before the router assumes there are no local members of a group.
