NOTE: Egress Interface Selection (EIS) works only with IPv4 routing.
When the feature is enabled using the
management egress-interface-selection
command, the
following events are performed:
• The CLI prompt changes to the EIS mode.
• In this mode, you can run the
application
and
no application
commands
• Applications can be configured or unconfigured as management applications using the
application
or
no application
command. All configured applications are considered as management applications
and the rest of them as non-management applications.
• All the management routes (connected, static and default) are duplicated and added to the
management EIS routing table.
• Any new management route added is installed to both the EIS routing table and default routing table.
• For management applications, route lookup is preferentially done in the management EIS routing table
for all traffic. management port is the preferred egress port. For example, if SSH is a management
application, an SSH session to a front-panel port IP on the peer box is initiated via management port
only, if the management port is UP and management route is available.
• If SSH request is received on the management port destined to the management port IP address, the
response to the request is sent out of the management port by performing a route lookup in the EIS
routing table
• If the SSH request is received on the front-end port destined for the front-end IP address, the response
traffic is sent by doing a route lookup in the default routing table only.
• If the management port is down or route lookup fails in the management EIS routing table, packets are
dropped.
• For all non-management applications, traffic exits out of either front-end data port or management port
based on route lookup in default routing table.
• Ping and traceroute are always non-management applications and route lookup for these applications is
done in the default routing table only.
• For ping and traceroute utilities that are initiated from the switch, if reachability needs to be tested
through routes in the management EIS routing table, you must configure ICMP as a management
application.
• If ping and traceroute are destined to the management port IP address, the response traffic for these
packets is sent by doing route lookup in the EIS routing table.
When the feature is disabled using the
no management egress-interface-selection
command, the
following operations are performed:
• All management application configuration is removed.
• All routes installed in the management EIS routing table are removed.
