set gmrp interfacemode

This command enables GARP Multicast Registration Protocol on a selected interface. If an

interface which has GARP enabled is enabled for routing or is enlisted as a member of a port-

channel (LAG), GARP functionality will be disabled on that interface. GARP functionality will

subsequently be re-enabled if routing is disabled and port-channel (LAG) membership is removed

from an interface that has GARP enabled.

no set gmrp interfacemode

This command disables GARP Multicast Registration Protocol on a selected interface. If an

interface which has GARP enabled is enabled for routing or is enlisted as a member of a port-

channel (LAG), GARP functionality will be disabled on that interface. GARP functionality will

subsequently be re-enabled if routing is disabled and port-channel (LAG) membership is removed

from an interface that has GARP enabled.

set gmrp interfacemode all

This command enables GARP Multicast Registration Protocol on all interfaces. If an interface

which has GARP enabled is enabled for routing or is enlisted as a member of a port-channel

(LAG), GARP functionality will be disabled on that interface. GARP functionality will

subsequently be re-enabled if routing is disabled and port-channel (LAG) membership is removed

from an interface that has GARP enabled.

all interfaces.

Join Timer

Specifies the interval between the transmission of GARP PDUs registering (or

re-registering) membership for an attribute. Current attributes are a VLAN or

multicast group. There is an instance of this timer on a per-Port, per-GARP par-

ticipant basis. Permissible values are 10 to 100 centiseconds (0.1 to 1.0 sec-

onds). The factory default is 20 centiseconds (0.2 seconds). The finest

granularity of specification is 1 centisecond (0.01 seconds).

Leave Timer

Specifies the period of time to wait after receiving an unregister request for an

attribute before deleting the attribute. Current attributes are a VLAN or multi-

cast group. This may be considered a buffer time for another station to assert

registration for the same attribute in order to maintain uninterrupted service.

There is an instance of this timer on a per-Port, per-GARP participant basis. Per-

missible values are 20 to 600 centiseconds (0.2 to 6.0 seconds). The factory

default is 60 centiseconds (0.6 seconds). The finest granularity of specification

is 1 centisecond (0.01 seconds).

LeaveAll Timer

This Leave All Time controls how frequently LeaveAll PDUs are generated. A

LeaveAll PDU indicates that all registrations will shortly be deregistered. Par-

ticipants will need to rejoin in order to maintain registration. There is an

instance of this timer on a per-Port, per-GARP participant basis. The Leave All

Period Timer is set to a random value in the range of LeaveAllTime to

1.5*LeaveAllTime. Permissible values are 200 to 6000 centiseconds (2 to 60

seconds). The factory default is 1000 centiseconds (10 seconds). The finest

granularity of specification is 1 centisecond (0.01 seconds).

Port GMRP Mode

Indicates the GMRP administrative mode for the port. It may be enabled or dis-

abled. If this parameter is disabled, Join Time, Leave Time and Leave All Time

have no effect. The factory default is disabled.

show mac-address-table gmrp

This command displays the GARP Multicast Registration Protocol (GMRP) entries in the

Multicast Forwarding Database (MFDB) table.

Mac Address

A unicast MAC address for which the switch has forwarding and or filtering

information. The format is 6 or 8 two-digit hexadecimal numbers that are sepa-

rated by colons, for example 01:23:45:67:89:AB. In an IVL system the MAC

address will be displayed as 8 bytes.

Type

This displays the type of the entry. Static entries are those that are configured by

the end user. Dynamic entries are added to the table as a result of a learning pro-

cess or protocol.

Description

The text description of this multicast table entry.

Interfaces

The list of interfaces that are designated for forwarding (Fwd:) and filtering

(Flt:).

Internet Group Management Protocol (IGMP) Commands

This chapter provides a detailed explanation of the IGMP commands. The commands are divided

into two functional groups:

•

Show commands display switch settings, statistics, and other information.

•

Configuration commands configure features and options of the switch. For every

configuration command, there is a show command that displays the configuration setting.

set igmp

This command enables IGMP Snooping on the system. The default value is disable.

Note:

The IGMP application supports the following:

•

Global configuration or per interface configuration. Per VLAN configuration is unsupported

in the IGMP snooping application.

•

Validation of the IP header checksum (as well as the IGMP header checksum) and discarding

of the frame upon checksum error.

•

Maintenance of the forwarding table entries based on the MAC address versus the IP address.

•

Flooding of unregistered multicast data packets to all ports in the VLAN.

Snooping enabled is enabled for routing or is enlisted as a member of a port-channel (LAG),

IGMP Snooping functionality will be disabled on that interface. IGMP Snooping functionality will

subsequently be re-enabled if routing is disabled or port-channel (LAG) membership is removed

from an interface that has IGMP Snooping enabled.

set igmp groupmembership-interval

This command sets the IGMP Group Membership Interval time on the system. The Group

Membership Interval time is the amount of time in seconds that a switch waits for a report from a

particular group on a particular interface before deleting the interface from the entry. This value

must be greater than the IGMP Maximum Response time value. The range is 2 to 3600 seconds.

Default

260

Format

set igmp groupmembership-interval

<2-3600>

Mode

Global Config

no set igmp groupmembership-interval

This command sets the IGMP Group Membership Interval time on the system to 260 seconds.

This command sets the IGMP Maximum Response time on the system. The Maximum Response

time is the amount of time in seconds that a switch will wait after sending a query on an interface

because it did not receive a report for a particular group in that interface. This value must be less

than the IGMP Query Interval time value. The range is 1 to 3599 seconds.
