Configure the interfaces
These sections describe how to configure Gigabit interfaces and also provide examples of configuring the router interfaces:
Configure Gigabit Ethernet interfaces
Procedure
|
Step 1 |
enable Example:Enables privileged EXEC mode. Enter your password if prompted. |
|
Step 2 |
configure terminal Example:Enters global configuration mode. |
|
Step 3 |
interface TwoGigabitEthernet slot/subslot/port Example:Configures a GigabitEthernet interface.
|
|
Step 4 |
ip address ip-address mask [secondary] dhcp pool Example:Assigns an IP address to the GigabitEthernet
|
|
Step 5 |
negotiation auto Example:Selects the negotiation mode.
|
|
Step 6 |
end Example:Ends the current configuration session and returns to privileged EXEC mode. |
Configure the interfaces: Example
This example shows the interface TwogigabitEthernet command being used to add the interface and set the IP address. 0/0/1 is the slot/subslot/port. The ports are numbered 0 to 5.
Router# show running-config interface TwogigabitEthernet 0/0/1
Building configuration...
Current configuration : 108 bytes
!
interface TwoGigabitEthernet0/0/1
no ip address
shutdown
negotiation auto
mka policy priority100
end
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface TwogigabitEthernet 0/0/1 Note |
Several Cisco platforms, NIMs, and SM cards support configuring multiple-rate SFPs on same interface, e.g., 1G SFP or 10G SFP+ on a 10G port. In a port-channel bundle, all member interfaces should be of same speed, and duplex. It is recommended to use duplex interfaces of the same speed as member interfaces for configuring a port-channel. For more information about interfaces that support multiple-rate SFPs, see the corresponding datasheets. |
View a list of all interfaces: Example
In this example, the show interfaces summary, and show platform software status control-process brief commands are used to display all the interfaces for C8375-E-G2:
