DHCP PROPERTIES
DHCP SERVER
Dynamic Host Configuration Protocol (DHCP).
Disabled
(default).
Enabled
: Only one switch on a given VLAN may have an active DHCP service, and that VLAN must have a static IP itself.
One switch with multiple VLANs may have multiple DHCP servers.
DHCP SERVER RANGE START
Sets start IP address in the DHCP pool. Pool must begin at an address higher than the IP address of the server.
DHCP SERVER RANGE END
Sets last available IP address in the DHCP pool. Cannot exceed the last valid IP value in the IP/Subnet Mask range.
IGMP
Intergroup Management Protocol (
IGMP
) allows for packet filtering and forwarding by the switch based on multicast groups.
Networks using sACN can take full advantage of IGMP by reducing the traffic on the link to the gateway to just the Network
DMX Universes the gateway is configured to listen to.
IGMP QUERIER
Disabled
(default).
Enabled
: Allows switch to query and construct a forwarding-table based on end device subscriptions to multicast group
addresses. (i.e., the Querier can tell that a 2-port DMX512 gateway is interested in Univ 8 and Univ 37, if so patched, and
will route those sACN Universes, and only those, on the link on which the gateway is connected.) One querier is required
be active on a given VLAN using IGMP routing. However, for reliability reasons, it is highly recommended to have two or
more.
IGMP SNOOPING
Disabled
(default)
Enabled
: Allows the switch to forward multicast data packets according to IGMP forwarding-tables build by the Querier.
All switches on a VLAN using IGMP should have snooping enabled, including the switches acting as an IGMP Querier.
