Behavior of Various Applications for Switch-Destined Traffic

This section describes the different system behaviors that occur when traffic is terminated on the switch. Traffic has not originated from

the switch and is not transiting the switch. Switch-destined traffic is applicable only for applications which act as server for the TCP

session and also for ICMP-based applications like ping and traceroute. FTP, SSH, and Telnet are the applications that can function as

servers 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 is

management port IP address, management port is the preferred egress port selected based on route lookup in EIS table. If the

management 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 default

routing table.

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.
