interface.

Egress Interface Selection (EIS)
EIS allows you to isolate the management and front-end port domains by preventing switch-initiated traffic routing between the two
domains. This feature provides additional security by preventing flooding attacks on front-end ports. The following protocols support
EIS: DNS, FTP, NTP, RADIUS, sFlow, SNMP, SSH, Syslog, TACACS, Telnet, and TFTP. This feature does not support sFlow on
stacked units.
When you enable this feature, all management routes (connected, static, and default) are copied to the management EIS routing
table. Use the
management route
command to add new management routes to the default and EIS routing tables. Use the
show
ip management-eis-route
command to view the EIS routes.
