Mapping Of Management Applications And Traffic Type - Dell S4820T Configuration Manual

Mapping of Management Applications and Traffic Type

The following table summarizes the behavior of applications for various types of traffic when the
management egress interface selection feature is enabled.
Table 33. Mapping of Management Applications and Traffic Type
Traffic type / Switch initiated traffic
Application
type
EIS Management is the
Management preferred egress port
Application selected based on route
lookup in EIS table. If the
management port is down
or the route lookup fails,
packets are dropped.
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
Internet Group Management Protocol (IGMP)
Switch-destined traffic
If source TCP/UDP port matches a
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
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
Traffic from
management port
to data port and
from data port to
management port
is blocked
