config igmp_snooping
seconds.
leave_timer <sec 1-16711450> − Specifies the amount of time a
Multicast address will stay in the database before it is deleted, after it
has sent out a leave group message. An entry of zero (0) specifies
an immediate deletion of the Multicast address. The default is 2
seconds.
state [enable | disable] − Allows you to enable or disable IGMP
snooping for the specified VLAN.
Restrictions Only administrator-level users can issue this command.
Example usage:
To configure IGMP snooping:
DES-3526:4#config igmp_snooping default host_timeout 250 state
enable
Command: config igmp_snooping default host_timeout 250 state
enable
Success.
DES-3526:4#
config igmp_snooping querier
Purpose This command configures IGMP snooping querier.
Syntax
config igmp_snooping querier [<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]
Description 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.
Parameters
<vlan_name 32> − The name of the VLAN for which IGMP snooping
querier is to be configured.
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:
