Multimedia Traffic Control with IP Multicast (IGMP)
How IGMP Operates
Listing the Forced Fast-Leave Configuration
The Forced Fast-Leave configuration data is available in the switch’s MIB
(Management Information Base), and includes the state (enabled or disabled)
for each port and the Forced-Leave Interval for all ports on the switch.
Note on Port For the IGMP MIB commands that are described on the next few pages, the
Numbers
HP Procurve Switch 5300xl uses 26 ports for each slot. This is true regardless
of the type of modules that you have installed in the slots. The following port
numbering is used:
■ Slot A = ports 1-24 (ports 25 and 26 are reserved)
■ Slot B = ports 27-50 (ports 51 and 52 are reserved)
To List the Forced Fast-Leave State for all Ports in the Switch. Go to
the switch’s command prompt and use the
walkmib command, as shown below.
1. From the Main Menu, select:
5. Diagnostics . . .
4. Command Prompt
2. Do one of the following:
• If VLANs are not enabled on the switch, go to step 3.

i. You will be prompted to select a VLAN. For example:
ii. Because you can list the Forced Fast-Leave state for all ports on
the switch from any VLAN, just press
[Enter] to select the
displayed VLAN.
3. Enter either of the following walkmib command options:
walkmib hpSwitchIgmpPortForcedLeaveState
- OR -
walkmib 1.3.6.1.4.1.11.2.14.11.5.1.7.1.15.3.1.5
The resulting display lists the Forced Fast-Leave state for all ports in the
switch, by VLAN. (A port belonging to more than one VLAN will be listed
once for each VLAN, and if multiple VLANs are not configured, all ports
will be listed as members of the default VLAN.) The following command
produces a listing such as that shown in figure
