Interface Configuration
Module 3A - Physical Interface
3A-2
Objectives • Identify Interface Types
• Define Physical Interfaces
• L2 ports
• L3ports
• Management
• Define Logical Interfaces
• Loopback
• Null
• Port-Channel
• VLANs
• Utilize show interface commands
• Familiarize with the Management Route Table
• Discuss Loopback Interfaces
3A-3
Interface Types
Interface Type Modes
Possible Default Mode
Require Creation
Default State
Physical 1-Gigabit Ethernet, 10-Gigabit Ethernet
interfaces, and SONET interfaces L2, L3 Unset No
Shutdown (disabled)
Management Located on the RPM and provides
management access N/A N/A No
Shutdown (disabled)
Loopback Virtual interface in which the software
emulates a physical interface L3 L3 Yes
No Shutdown (enabled)
Null Virtual interface that is always up, but no
traffic flows on this interface N/A N/A No Enabled
Port Channel Virtual interface that provides redundancy
by allowing the aggregation of up to 16 physical interfaces
Simultaneously Configuring More Than One Interface
NOTE: Correct syntax needs spaces before and after the comma or hyphen.

• If an interface range definition will be used many times, a macro can be defined to represent the interface range – Force10(conf)# define interface-range {name}
GigabitEthernet slot/{port {–|,} port}
• To apply the macro, use the same command as the interface range, but specify a macro instead – Force10(conf)# interface range macro {name}
Force10#sh ip management-route all Destination Gateway State ----------- ------- ----- 10.11.4.0/24 172.16.1.250 Active 172.16.1.0/24 ManagementEthernet 0/0 Connected 0.0.0.0/0 172.16.1.250 Inactive
Force10#sh ip route Codes: C - connected, S - static, R - RIP B - BGP, IN - internal BGP, EX - external BGP, LO - Locally Originated O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1 N2 - OSPF NSSA external type 2, E1 - OSPF external type 1 E2 - OSPF external type 2, i - IS-IS, L1 - IS-IS level-1 L2 - IS-IS level-2, IA - IS-IS inter area, * - candidate default - non-active route + - summary route
Gateway of last resort is 1.2.3.4 to network 0.0.0.0
Destination Gateway Dist/Metric Last Change ----------- ------- ----------- ----------- *S 0.0.0.0/0 via 1.2.3.4, Po 1 1/0 00:00:06 C 10.0.0.0/24 Direct, Gi 0/0 0/0 1d19h C 34.94.168.0/21 Direct, Vl 12 0/0 2d17h C 92.68.251.0/24 Direct, Gi 0/10 0/0 2d17h
Management Route Table Example
A. A host with an IP address (10.11.4.18) can telnet to the Ma0/0 interface (172.16.1.181)
B. …because a management route to the 10.11.4.0/24 subnet was configured
C. …using the default gateway, 172.16.1.250, of the management network
D. The configured default management route 0.0.0.0/0 via 172.16.1.250 is inactive
E. …because it exists in the main system route table

A. Configure the IP address for the Management Ethernet interface(s)
B. Enable the interface using the command “no shutdown”
C. Configure static routes to networks that will have management hosts
D. Verify static management routes are active using the command “show ip management-route all”
