Configuring Physical Ethernet Interfaces
-
NC55-MPA-12T-S supports 1G optics in eight ports. The ports are 0 to 3 and 8 to 11.
-
NC55-MPA-12T-S supports 10G optics in ports 4 to 7.
Use this procedure to create a basic Ethernet interface configuration.
Procedure
Step 1 |
show version Example:
(Optional) Displays the current software version, and can also be used to confirm that the router recognizes the interface module. |
||
Step 2 |
show interfaces [GigE | TenGigE | TwentyFiveGigE| FortyGigE | HundredGigE] interface-path-id Example:
(Optional) Displays the configured interface and checks the status of each interface port. |
||
Step 3 |
configure Example:
Enters global configuration mode. |
||
Step 4 |
interface [GigE | TenGigE| TwentyFiveGigE| FortyGigE | HundredGigE] interface-path-id Example:
Enters interface configuration mode and specifies the Ethernet interface name and notation rack/slot/module/port. Possible interface types for this procedure are:
|
||
Step 5 |
ipv4 address ip-address mask Example:
Assigns an IP address and subnet mask to the interface.
|
||
Step 6 |
mtu bytes Example:
(Optional) Sets the MTU value for the interface.
|
||
Step 7 |
no shutdown Example:
Removes the shutdown configuration, which forces an interface administratively down. |
||
Step 8 |
show interfaces [GigE TenGigE TwentyFiveGigE TwentyFiveGigE FortyGigE HundredGigE ] interface-path-id Example:
(Optional) Displays statistics for interfaces on the router. |
Example
This example shows how to configure an interface for a 100-Gigabit Ethernetinterface module:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface HundredGigE 0/7/0/0
RP/0/RP0/CPU0:router(config-if)# ipv4 address 172.18.189.38 255.255.255.224
RP/0/RP0/CPU0:router(config-if)# mtu 2000
RP/0/RP0/CPU0:router(config-if)# no shutdown
RP/0/RP0/CPU0:router(config-if)# end
