Column Meaning
Interface The unit/slot/port of the interface that this row in the table describes.
Join Timer The interval between the transmission of GARP PDUs registering (or reregistering) 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 participant basis. Permissible values are 10 to 100 centiseconds (0.1 to 1.0
seconds). The factory default is 20 centiseconds (0.2 seconds). The finest granularity of
specification is 1 centisecond (0.01 seconds).
Leave Timer The period of time to wait after receiving an unregister request for an attribute before deleting the
attribute. Current attributes are a VLAN or multicast group. This may be considered a buer 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. Permissible
values are 20 to 600 centiseconds (0.2 to 6.0 seconds). The factory default is 60 centiseconds (0.6
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. Participants 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).
Port GMRP
Mode
The GMRP administrative mode for the port. It may be enabled or disabled. If this parameter is
disabled, Join Time, Leave Time and Leave All Time have no eect.
show mac-address-table gmrp
This command displays the GMRP entries in the Multicast Forwarding Database (MFDB) table.
Format
show mac-address-table gmrp
Mode Privileged EXEC
Column Meaning
VLAN ID The VLAN in which the MAC Address is learned.
MAC Address A unicast MAC address for which the switch has forwarding and or filtering information. The format
is 6 two-digit hexadecimal numbers that are separated by colons, for example 01:23:45:67:89:AB.
Type 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 process 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:).
Port-Based Network Access Control Commands
This section describes the commands used to configure port-based network access control (IEEE
802.1X). Port-based network access control allows you to permit access to network services only to and
devices that are authorized and authenticated.
