Multimedia Traffic Control with IP Multicast (IGMP)
How IGMP Operates
Figure 4-5. Example Listing the Forced Fast-Leave State for a Single Port on the Default
VLAN
Configuring Per-Port Forced Fast-Leave IGMP
In the factory-default configuration, Forced Fast-Leave is disabled for all ports
on the switch. To enable (or disable) this feature on individual ports, use the
switch’s setmib command, as shown below.
Configuring Per-Port Forced Fast-Leave IGMP on Ports. This
procedure enables or disables Forced Fast-Leave on ports in a given VLAN.
(See the “Note on VLAN Numbers” on page 4-18.)
Syntax:
setmib hpSwitchIgmpPortForcedLeaveState.< vlan number >< .port number >
-i < 1 | 2 >
- OR -
setmib 1.3.6.1.4.1.11.2.14.11.5.1.7.1.15.3.1.5.< vlan number >< .port number > -i
< 1 | 2 >
where:
1 = Forced Fast-Leave enabled
2 = Forced Fast-Leave disabled
For example, suppose that your switch has a six-port gigabit module in
slot A, and port C1 is a member of the default VLAN. In this case, the port
number is “49” (In the MIB, slot A = ports 1-24; slot B = ports 25-48; slot
C = ports 49-72, and so on.) To enable Forced Fast-Leave on C6 (53), you
would execute the following command and see the indicated result:
The 2 shows that Fast Forced-Leave
is disabled on the selected port.
The
6 specifies port A6.
The
1 indicates the default VLAN.
