Hardware configuration

The following sections describe the hardware configurations.

Configuring line cards

Define line card types explicitly based on the system type.

Configuring line card type configuration for the 7750 SR-1 with one pluggable MDA card

configure card 1 card-type iom-1
configure card 1 level he
configure card 1 mda 1 mda-type me6-100gb-qsfp28
Use the following command to show the operational status of the card.
show card state

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 124 }

Configuring 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 128 }
Use the following command to display the port information. 
show port
