If you configure a source interface is for any EIS management application, EIS might not coexist with that
interface and the behavior is undefined in such a case. You can configure the source interface for the
following applications: FTP, ICMP (ping and traceroute utilities), NTP, RADIUS, TACACS, Telnet, TFTP,
syslog, and SNMP traps. Out of these applications, EIS can coexist with only syslog and SNMP traps
because these applications do not require a response after a packet is sent.
The switch also processes user-specified port numbers for applications such as RADIUS, TACACS, SSH,
and sFlow. The OS maintains a list of configured management applications and their port numbers. You
can configure two default routes, one configured on the management port and the other on the front-
end port.
Two tables, namely, Egress Interface Selection routing table and default routing table, are maintained. In
the preceding table, the columns Client and Server indicate that the applications can act as both a client
and a server within the switch. The Management Egress Interface Selection table contains all
management routes (connected, static and default route). The default routing table contains all
management routes (connected, static and default route) and all front-end port routes.

Enabling and Disabling Management Egress Interface Selection

You can enable or disable egress-interface-selection using the management egress-interface-
selection command.
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.
