How IGMP Operates

Internal VLAN Number for the Default VLAN

Note: Internal VLAN numbers reflect the sequence in which VLANs are created, and are not related to the unique VID assigned to each VLAN. (See the

Sequential Port Numbers

The 2 at the end of a port listing shows that Forced Fast-Leave is disabled on the corresponding port.

The 1 at the end of a port listing shows that Forced Fast-Leave is enabled on the corresponding port.

“Note on VLAN Numbers on page 4-19.)

Ports 1-6:6- Port 109/1000T Module in Slot A

To List the Forced Fast-Leave State for a Single Port. (See the “Note on VLAN Numbers” on page 4-19.)

Go to the switch’s command prompt and use the getmib command, as shown below.

Syntax:

getmib hpSwitchIgmpPortForcedLeaveState.<vlan number><.port number>

- OR -

getmib 1.3.6.1.4.1.11.2.14.11.5.1.7.1.15.3.1.5.<vlan number><.port number>

For example, the following command to list the state for port A6 (which, in this case, belongs to the default VLAN) produces the indicated listing:

The 2 shows that Fast Forced-Leave is disabled on the selected port.

The 6 specifies port A6.

The 1 indicates the default VLAN. (See the “Note on VLAN Numbers” on page 4-19.)
