LABEL DESCRIPTION
Active Select Active to enable DVMRP on the switch. You should do this if you want the switch to
act as a multicast router.
Threshold Threshold is the maximum time to live (TTL) value. TTL is used to limit the scope of
multicasting. You should reduce this value if you do not wish to flood Layer 3 devices many
hops away with multicast traffic. This applies only to multicast traffic this switch sends out.
Index Index is the DVMRP configuration for the IP routing domain defined under Network . The
maximum number of DVMRP configurations allowed is the maximum number of IP routing
domains allowed on the switch. See Section 7.6 on page 75 for more information on IP
routing domains.
Network This is the IP routing domain IP address and subnet mask you set up in IP Setup.
VID DVMRP cannot be enabled on the same VLAN group across different IP routing domains,
that is, you cannot have duplicate VIDs for different DVMRP configurations (see Figure 94
on page 192 ).
Active Select Active to enable DVMRP on this IP routing domain.
Apply Click Apply to save your changes to the switch’s run-time memory. The switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel
to save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this part of the screen afresh.
