This feature provides additional security by preventing flooding attacks on front-end ports. The following protocols supportEIS: DNS, FTP, NTP, RADIUS, sFlow, SNMP, SSH, Syslog, TACACS, Telnet, and TFTP. This feature does not support sFlow onstacked units.When you enable this feature, all management routes (connected, static, and default) are copied to the management EIS routingtable. Use the management route command to add new management routes to the default and EIS routing tables. Use the showip management-eis-route command to view the EIS routes.372 Interfaces
