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
