      Command Parameters
         
         
            
               - maxadvertinterval <2-180>
 
               - Configures the maximum number (in
                  seconds) between successive advertisements. For this change to take effect, you
                  must save the configuration, and then reset the switch. The default is 20.
 
            
            
               - maxinitadvertinterval <2-180>
 
               - Configures the maximum number (in
                  seconds) between successive initial advertisements. For this change to take
                  effect, you must save the configuration, and then reset the switch. The default is
                  2.
 
            
            
               - maxinitadvertisements <2-15>
 
               - Configures the maximum number of
                  initial multicast advertisements after initialization. For this change to take
                  effect, you must save the configuration, and then reset the switch. The default is
                  3.
 
            
            
               - minadvertinterval <3-180>
 
               - Configures the minimum number (in
                  seconds) between successive advertisements. For this change to take effect, you
                  must save the configuration, and then reset the switch. The default is 15.
 
            
            
               - neighdeadinterval <2-180>
 
               - Configures the multicast router
                  discovery dead interval-the number of seconds the multicast route neighbors for
                  the switch must wait before assuming that the multicast router is down. The
                  default is 60.
