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 2. Mapping of Management Applications and Traffic Type
Traffic type /
Application
type
Switch initiated traffic Switch destined traffic Transit Traffic
EIS
Management
Application
Management is the
preferred egress port
selected based on route
lookup in EIS table . If the
management port is down
or route lookup fails
packets are dropped.
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
Traffic from
management port
to data port and
from data port to
management port
is blocked
Non-EIS
management
application
Front-end default route
will take higher
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.
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
Traffic from
management port
to data port and
from data port to
management port
is blocked
• 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 is the case 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 is the case where traffic is terminated on the switch. Traffic has not originated from the switch and is
not transiting the switch.
All traffic destined to the switch which is received on management or front end data port is accepted by
the switch. 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 is the case where traffic is originating from the switch.
