Default Behavior: Route lookup is done in the default routing table and appropriate egress port is selected. Protocol ftp Behavior when EIS is Enabled EIS Behavior Behavior when EIS is Disabled Default Behavior http EIS Behavior Default Behavior ssh EIS Behavior Default Behavior Snmp (snmp mib response) EIS Behavior Default Behavior telnet EIS Behavior Default Behavior icmp (ping and traceroute) EIS Behavior for ICMP Default Behavior 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 406 Internet Group Management Protocol (IGMP)
