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, HTTP, IGMP, NTP, RADIUS, SNMP, SSH, Syslog, TACACS,
Telnet, and TFTP.
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.
Important Points to Remember
•
Deleting a management route removes the route from both the EIS routing table and the default routing
table.
•
If the management port is down or route lookup fails in the management EIS routing table, the outgoing
interface is selected based on route lookup from the default routing table.
•
If a route in the EIS table conflicts with a front-end port route, the front-end port route has precedence.
•
Due to protocol, ARP packets received through the management port create two ARP entries (one for
the lookup in the EIS table and one for the default routing table).
Configuring EIS
EIS is compatible with the following protocols: DNS, FTP, NTP, RADIUS, sFlow, SNMP, SSH, Syslog, TACACS,
Telnet, and TFTP.
To enable and configure EIS, use the following commands:
1
Enter EIS mode.
