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 7.7 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. |
