Cli Configuration Commands - Avaya 1000 Series Configuration Manual

IGMP snooping currently supports the following configurations:
• Global enabling or disabling of IGMP snooping. When disabled, IGMP snooping does not
process any IGMP related packets. When enabled, the packets are processed only on
the VLANs on which IGMP snooping is enabled
• Enabling or disabling of IGMP snooping on a specified VLAN. By default, IGMP snooping
is disabled on all VLANs.
• Configuring the Secure Router to specify the interface and VLAN on which a layer 3
multicast router is configured
• Enabling or disabling of querier on a VLAN. On enabling the querier, the Secure Router
will send periodic query messages on the VLAN
• Enabling or disabling of fast leave. If enabled, the VLAN leaves the group immediately
after receiving a membership leave message. If disabled, the router sends query
messages 3 times to verify whether any host is still interested in receiving the multicast
stream on this VLAN.
• Configuring IGMP version on a VLAN. This parameter specifies the version of IGMP
message to be used on a VLAN. Version 1 and 2 are supported.
• Configuring query interval on a VLAN. This parameter specifies the query interval in
milliseconds for query messages to be sent on a VLAN (default is 125 000 milliseconds).
• Configuring last member query interval. This parameter specifies the interval in
millisecond of the query message to be sent upon receiving a membership leave message
(default is 1000 milliseconds)
• Configuring maximum response time in centi-seconds (default 100 centi-seconds or 1000
milliseconds). This value is used to calculate the membership expiry timer using the
following formula:
Membership expiry = 2 x query interval + maximum response time in seconds
