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 79 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
136 on page 250 ).
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 screen afresh.
