• Enable the interface.
INTERFACE mode
no shutdown
• Congure a primary IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
The ip-address must be in dotted-decimal format (A.B.C.D) and the mask must be in slash format (/xx).
Add the keyword secondary if the IP address is the interface’s backup IP address.
Example of the show ip interface Command
You can only congure one primary IP address per interface. You can congure up to 255 secondary IP addresses on a single interface.
To view all interfaces to see with an IP address assigned, use the show ip interfaces brief command in EXEC mode as shown in
View Basic Interface Information.
To view IP information on an interface in Layer 3 mode, use the show ip interface command in EXEC Privilege mode.

Egress Interface Selection (EIS)
EIS allows you to isolate the management and front-end port domains by preventing switch-initiated trac routing between the two
domains. This feature provides additional security by preventing ooding 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.
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 conicts 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).
Conguring EIS
EIS is compatible with the following protocols: DNS, FTP, NTP, RADIUS, sFlow, SNMP, SSH, Syslog, TACACS, Telnet, and TFTP.
