Because this feature is specific to the management port, this feature can coexist with VLT andnothing specific needs to be done in this feature to handle VLT scenario.DHCP• If DHCP Client is enabled on the management port, a management default route is installed to the switch.• If management EIS is enabled, this default route is added to the management EIS routing table and the default routing table.ARP learn enable• When ARP learn enable is enabled, the switch learns ARP entries for ARP Request packets even if the packet is not destined to an IPconfigured in the box.• The ARP learn enable feature is not applicable to the EIS routing table. It is applicable to the default routing table only to avoidunnecessary double ARP entriesSflowsFlow management application is supported only in standalone boxes and switch shall throw error message if sFlow is configured instacking environmentDesignating a Multicast Router InterfaceTo designate an interface as a multicast router interface, use the following command.Dell Networking OS also has the capability of listening in on the incoming IGMP general queries and designate those interfaces as themulticast router interface when the frames have a non-zero IP source address. All IGMP control packets and IP multicast data trafficoriginating from receivers is forwarded to multicast router interfaces.390 Internet Group Management Protocol (IGMP)
