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.
