This chapter describes the introductory information for configuring Ethernet interfaces on Cisco 8000 Series Routers, including the module scope and the prerequisites that must be met before configuration.
Ethernet interface configuration
Describes the scope of Ethernet interface configuration on Cisco 8000 Series Routers, including the distributed 10-Gigabit, 25-Gigabit, 40-Gigabit, 100-Gigabit, and 400-Gigabit Ethernet architectures and features that interconnect the router with core routers, edge routers, and Layer 2 and Layer 3 switches in POPs.
Prerequisites for configuring Ethernet interfaces
Lists the prerequisites that must be met before you configure Ethernet interfaces on Cisco 8000 Series Routers, including access to supported hardware, knowledge of the interface IP address, and the generalized interface naming notation.
Ethernet interface fundamentals
This topic covers the fundamentals of Ethernet interface, such as supported hardware, ethernet protocol standards, flow control and so on.
Network interface speed and autonegotiation
Describes autonegotiation as an IEEE 802.3 Ethernet standard that enables connected routers to determine the highest common transmission parameters, such as mode, speed, and flow control, to optimize link bandwidth utilization.
Interfaces and subinterfaces on the router
In Cisco IOS XR, interfaces are, by default, main interfaces (also known as trunk interfaces) on Cisco 8000 Series Routers, under which the system creates logical subinterfaces for efficient network segmentation and management.
Layer 2 VPN on Ethernet interfaces
Describes Layer 2 Virtual Private Network (L2VPN) connections that emulate LAN behavior across a Layer 2 switched, IP, or MPLS-enabled IP network.
Carrier delay on physical interfaces
Describes how the carrier delay introduces a delay in processing interface link-state notifications on physical Ethernet interfaces so that the interface link has time to stabilize.
Interface statistics
This topic covers interface statistics, traffic rate displays, and real-time monitoring commands.
