Setup Guide

EIS behavior for ICMP: ICMP packets do not have TCP/UDP ports. In this case, to perform an EIS route lookup for ICMP-based
applications (ping and traceroute), you must configure ICMP as a management application. If the management port is down or the route
lookup fails, packets are dropped.
If source IP address does not match the management port IP address route lookup is done in the default routing table.
Default Behavior: Route lookup is done in the default routing table and appropriate egress port is selected.

Interworking of EIS With Various Applications
Stacking
• The management EIS is enabled on the master and the standby unit.
• Because traffic can be initiated from the Master unit only, the preference to management EIS table for switch-initiated traffic and all
its related ARP processing is done in the Master unit only.
• ARP-related processing for switch-destined traffic is done by both master and standby units.
VLT
VLT feature is for the front-end port only. Because this feature is specific to the management port, this feature can coexist with VLT and
nothing 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 IP
configured 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 avoid
unnecessary double ARP entries
Sflow
sFlow management application is supported only in standalone boxes and switch shall throw error message if sFlow is configured in
stacking environment
Designating a Multicast Router Interface
To designate an interface as a multicast router interface, use the following command.
Dell EMC Networking OS also has the capability of listening in on the incoming IGMP general queries and designate those interfaces as the
multicast router interface when the frames have a non-zero IP source address. All IGMP control packets and IP multicast data traffic
originating from receivers is forwarded to multicast router interfaces.
• Designate an interface as a multicast router interface.
