Hardware configuration
The following sections describe the hardware configurations.
Configuring power shelf and power modules
For systems with modular power shelves and power modules, define the power shelf and module type used in the system.
Configuring power shelf and power module type for 7750 SR-2se with one shelf and four modules
configure chassis router chassis-number 1 power-shelf 1 power-shelf-type ps-a4-shelf-dc
configure chassis router chassis-number 1 power-shelf 1 power-module 1 power-module-type ps-a-dc-6000
configure chassis router chassis-number 1 power-shelf 1 power-module 2 power-module-type ps-a-dc-6000
configure chassis router chassis-number 1 power-shelf 1 power-module 3 power-module-type ps-a-dc-6000
configure chassis router chassis-number 1 power-shelf 1 power-module 4 power-module-type ps-a-dc-6000Use the following command to display the operational status of the power shelf and modules.

Define line card types explicitly based on the system type.

===============================================================================Configuring ports and interfaces
Configure the physical port first, followed by an interface with an IPv4 or IPv6 address.
Each port is considered a connector that supports breakout. Configure the connector with the breakout type so that the appropriate ports are created and can be configured.
Configuring the connector breakout type
The following example displays the configuration of a connector breakout. The default port MTU value is 9212.
configure port 1/1/c1 admin-state enable
configure port 1/1/c1 connector breakout c1-100g
configure port 1/1/c1/1 admin-state enable
configure port 1/1/c1/1 description “To Peering LAN"Configuring the router interface
The interface is provided a name, an IP address, and is associated with a physical port as shown in the following example.
configure router "Base" interface "To-Peering-LAN" port 1/1/c1/1
configure router "Base" interface "To-Peering-LAN" ipv4 primary address 192.168.0.1 prefix-length 24
configure router "Base" interface "To-Peering-LAN" ipv6 address 2001:a8::4 prefix-length 124Configuring the system interface
The system interface is the router's loopback interface (like lo0 or loopback0) and is configured as shown in the following example.
configure router "Base" interface "system" ipv4 primary address 10.0.0.1 prefix-length 32
configure router "Base" interface "system" ipv6 address 2001:1::101 prefix-length 128show portPort status output

===============================================================================SR OS allows the user to enable a single instance of BFD in the interface context, in addition to timers, for both IPv4 and IPv6. The interface BFD state can be shared by specific protocols by enabling the bfd-liveness command under protocol-specific CLI context.
Enabling BFD for IPv4 and IPv6
configure router "Base" interface "Interface-to-R1" ipv4 bfd admin-state enableconfigure router "Base" interface "Interface-to-R1" ipv6 bfd admin-state enableUse the following command to display the protocol-specific BFD session on the router.
show router bfd sessionBFD session information output
The following example shows BFD sessions when bfd-liveness is enabled for the OSPF interface.
