Command Parameters
- generate-log
- Sets the Internet Group Management
Protocol (IGMP) log.
- generate-trap
- Sets the Internet Group Management
Protocol (IGMP) trap.
- immediate-leave-mode <multiple-user|one-user>
- Enables immediate leave mode to
users which is either a single user or multiple users.
- ssm [dynamic-learning] [group-range {A.B.C.D/X}]
- Enables and sets the Source
Specific Multicast (SSM) features.
- The parameter dynamic-learning
enables SSM dynamic learning.
- The parameter group-range
{A.B.C.D/X} configures the range group address and mask. The SSM range parameter
extends the default SSM range of 232/8 to include an IP multicast address. You can
configure existing applications without having to change their group
configurations. This parameter specifies an IP multicast address within the range
of 224.0.0.0 and 239.255.255.255. The default is 232.0.0.0. The address mask is
the IP address mask of the multicast group. The default is 255.0.0.0.
- ssm-map {A.B.C.D} {A.B.C.D} [enable]
- Enables the Source Specific
Multicast (SSM) map table for a specific entry or creates a static entry for a
specific group.
- The parameter {A.B.C.D} {A.B.C.D}
creates a static SSM channel table entry by specifying the group and source IP
addresses. The first IP address is an IP multicast address within the SSM range.
The second IP address is the source IP address and it it is an IP host address
that sends traffic to the group. The default for {A.B.C.D}{A.B.C.D} enable is
enable for each entry. The default is enable for each entry.
- ssm-map all
- Enables the Source Specific
Multicast (SSM) map table for all static entries.
- ssm-map {A.B.C.D} {A.B.C.D} [enable]
- Enables the Source Specific
Multicast (SSM) map table for a specific entry or creates a static entry for a
specific group.
- The parameter {A.B.C.D} {A.B.C.D}
creates a static SSM channel table entry by specifying the group and source IP
addresses. The first IP address is an IP multicast address within the SSM range.
The second IP address is the source IP address and it it is an IP host address
that sends traffic to the group. The default for {A.B.C.D}{A.B.C.D} enable is
enable for each entry. The default is enable for each entry.
- stream-timeout <10-432000>
- Specifies the activity timeout for
IGMP snooping streams in seconds. The default is 300 seconds.

Usage Guidelines
Before you disable or delete an ssm-map, always send IGMPv1 or IGMPv2 leave messages
from hosts that operate in IGMPv1 or IGMPv2. If you do not perform this action,
receiving and processing reports in SSM range on an IGMP interface enabled with IGMPv1
or IGMPv2 can lead to unexpected behavior.
