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.
Threshol
d 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
8.6 on page 110 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 177 on page 352 ).
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.
