Traffic has not originated fromthe switch and is not transiting the switch. Switch-destined traffic is applicable only for applications which act as server for the TCPsession and also for ICMP-based applications like ping and traceroute. FTP, SSH, and Telnet are the applications that can function asservers for the TCP session.EIS Behavior: If source TCP or UDP port matches an EIS management or a non-EIS management application and source IP address ismanagement port IP address, management port is the preferred egress port selected based on route lookup in EIS table. If themanagement port is down or the route lookup fails, packets are dropped.If the source TCP/UDP port or source IP address does not match the management port IP address, a route lookup is done in the defaultrouting table.EIS behavior for ICMP: ICMP packets do not have TCP/UDP ports. In this case, to perform an EIS route lookup for ICMP-basedapplications (ping and traceroute), you must configure ICMP as a management application. If the management port is down or the routelookup 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.Internet Group Management Protocol (IGMP) 389
