Traffic type / Switch initiated traffic
Application
type
Non-EIS Front-end default route
management will take higher
application precedence over
management default route
and SSH session to an
unknown destination uses
the front-end default route
only. No change in the
existing behavior.
• EIS is enabled implies that EIS feature is enabled and the application might or might not be configured
as a management application
• EIS is disabled implies that either EIS feature itself is disabled or that the application is not configured
as a management application
Transit Traffic
This phenomenon occurs where traffic is transiting the switch. Traffic has not originated from the switch
and is not terminating on the switch.
• Drop the packets that are received on the front-end data port with destination on the management
port.
• Drop the packets that received on the management port with destination as the front-end data port.
Switch-Destined Traffic
This phenomenon occurs where traffic is terminated on the switch. Traffic has not originated from the
switch and is not transiting the switch.
The switch accepts all traffic destined to the switch, which is received on management or front-end data
port. Response traffic with management port IP address as source IP address is handled in the same
manner as switch originated traffic.
Switch-Originated Traffic
This phenomenon occurs where traffic is originating from the switch.
1. Management Applications (Applications that are configured as management applications):
The management port is an egress port for management applications. If the management port is
down or the destination is not reachable through the management port (next hop ARP is not
resolved, and so on), and if the destination is reachable through a data port, then the management
application traffic is sent out through the front-end data port. This fallback mechanism is required.
2. Non-Management Applications (Applications that are not configured as management applications as
defined by this feature):
Internet Group Management Protocol (IGMP)
Switch-destined traffic
management port is down or route
lookup fails, packets are dropped
If source TCP/UDP port matches a
management application and the
source IP address is a management
port IP address, the 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
Transit Traffic
Traffic from
management port
to data port and
from data port to
management port
is blocked
