Description
This is the VLAN ID that, along with the VLAN Name, identifies the VLAN the user
wishes to modify the IGMP Snooping Settings for.
This is the VLAN Name that, along with the VLAN ID, identifies the VLAN the user
wishes to modify the IGMP Snooping Settings for.
The Query Interval field is used to set the time (in seconds) between transmitting
IGMP queries. Entries between 1 and 65535 seconds are allowed. Default = 125.
This determines the maximum amount of time in seconds allowed before sending an
IGMP response report. The Max Response Time field allows an entry between 1 and
25 (seconds). Default = 10.
Adjust this variable according to expected packet loss. If packet loss on the VLAN is
expected to be high, the Robustness Variable should be increased to accommodate
increased packet loss. This entry field allows an entry of 1 to 255. Default = 2.
This field specifies the maximum amount of time between group-specific query
messages, including those sent in response to leave group messages. Default = 1.
This is the maximum amount of time in seconds allowed for a host to continue
membership in a multicast group without the Switch receiving a host membership
report. Default = 260.
