Restrictions
Example usage:
To configure IGMP snooping:
DES-3800:4#config igmp_snooping default host_timeout 250 state
enable
Command: config igmp_snooping default host_timeout 250 state
enable
Success.
DES-3800:4#
config igmp_snooping querier
Purpose
Syntax
Description
Parameters
Switch receiving a host membership report. The default is 260
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.
fast_leave [enable | disable] – This parameter allows the user to
enable the 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.
NOTE: The Fast Leave function in the config
igmp_snooping command can only be implemented if IGMP
is disabled for all IP interfaces on the Switch. Configuring this
function when IGMP is enabled will produce the error
message "Cannot set Fast leave when IGMP is running" and
consequently will not be implemented.
This command configures IGMP snooping querier.
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]
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.
<vlan_name 32> − The name of the VLAN for which IGMP snooping
