YANG Data Models for Interfaces and Hardware Component

This chapter provides information about the YANG data models for interfaces and hardware component features.

Physical interfaces preconfiguration

This chapter provides information on how to preconfigure physical interfaces on Cisco routers, including benefits, guidelines, and step-by-step configuration procedures.

Management ethernet interface

This chapter covers Management Ethernet interface configuration, a network management process enabling secure router access and out-of-band traffic control.

Ethernet interfaces

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.

MTU

This chapter describes the maximum transmission unit (MTU) on Cisco 8000 Series Routers, including Ethernet MTU that governs the largest frame size on the Ethernet network, IP MTU that governs the largest IP packet size without fragmentation, MTU checks and scale limits, platform-specific configuration guidelines, and the procedure to configure IPv4 and IPv6 MTU on an interface.

LLDP

This chapter the Link Layer Discovery Protocol (LLDP) chapter, which describes how the router uses IEEE 802.1AB LLDP as a neighbor discovery protocol to advertise device information over Layer 2, explains features, such as LLDP frame and TLV formats, user-defined TLV values, LLDP operation, and so on.

Configure Ethernet Link OAM

This chapter describes the Ethernet Link OAM (IEEE 802.3ah), which covers neighbor discovery, error disable forwarding, MIB retrieval, miswiring detection, SNMP traps, link monitoring, and remote loopback, and includes tasks to configure an Ethernet OAM profile.

Configure Ethernet CFM

This chapter describes the Ethernet Connectivity Fault Management (CFM) chapter, which covers maintenance domains, services, maintenance points, MEP and CFM processing, protocol messages, continuity check, loopback, linktrace, configurable logging, hardware offload, and CFM over bundles, and includes tasks to configure domains, services, MEPs, cross-check, AIS, and Y.1731 AIS.

Configure Ethernet Performance Monitoring

This chapter describes the Ethernet performance monitoring chapter, which covers Ethernet SLA statistics measurement in a profile, Ethernet frame delay measurement for L2VPN services, and minimum delay bin support, and includes tasks to configure SLA statistics, frame delay measurement, and minimum delay bin support.

Configure Unidirectional Link Detection

This chapter describes the Unidirectional Link Detection (UDLD) chapter, which covers UDLD operation, types of fault detection, modes of operation, aging mechanism, state machines, and limitations, and includes the task to configure UDLD on an Ethernet interface on the router.

Configure Advanced Fault Propagation

This chapter describes the Advanced Fault Propagation chapter, which covers Link Loss Forwarding (LLF), link state monitor and propagation by CFM, remote link state propagation, and restrictions for LLF, and includes tasks to configure LLF for CFM and for Layer 2 transport on the router.

Configure Integrated Routing and Bridging

This chapter describes the Integrated Routing and Bridging (IRB) chapter, which covers the Bridge-Group Virtual Interface (BVI), packet flows between bridged and routed domains, supported environments, and tasks to configure a BVI, Layer 2 attachment circuits, and bridge domains.

Configure IP event dampening

This chapter describes the IP Event Dampening feature, interface state change events and thresholds, affected components and supported protocols, guidelines and limitations, and how to enable and verify IP event dampening on the Cisco 8000 Series Router.

Link bundling

This chapter provides high bandwidth and link redundancy for Cisco 8000 series routers running IOS XR software.

Virtual loopback and null interfaces

This chapter describes configuring virtual loopback and null interfaces to improve routing reliability and manage network traffic effectively.

GRE Tunnels

This chapter describes configuring GRE tunnels, covering encapsulation, decapsulation, and NVGRE load-balancing for Cisco 8000 series routers.

802.1Q VLAN interfaces

This chapter describes configuring 802.1Q VLAN interfaces, subinterfaces, and attachment circuits for Cisco 8000 Series Routers.

IP-in-IP tunnels

This chapter describes configuring IP-in-IP tunnels, including encapsulation, decapsulation, TTL management, and load balancing.

Generic UDP encapsulation

This chapter details Generic UDP Encapsulation (GUE) configuration, covering tunnel setup, port assignment, and load balancing on Cisco routers.
