: 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 utilites), 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.
For applications such as RADIUS, TACACS, SSH, and sFlow, user-specified port numbers are also
processed by the switch. 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.
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.
