Operate and maintain
Documents under this category provide functional descriptions and procedures for configuring, operating, and maintaining 7705 SAR software.
- Basic System Configuration Guide
  This guide provides an overview of the CLI and describes 7705 SAR boot options file (BOF) configuration, file system management, and basic system management such as node timing and synchronization.
- Interface Configuration Guide
  This guide describes the functionality of the 7705 SAR cards, modules, and ports and how to configure these components.
- MPLS Guide
  This guide describes how to configure MPLS, RSVP-TE, PCEP, and LDP protocols on the 7705 SAR.
- Quality of Service Guide
  This guide describes the Quality of Service (QoS) functionality provided by the 7705 SAR and how to configure and implement QoS on the router.
- Router Configuration Guide
  This guide describes how to configure logical IP routing interfaces, VRRP filtering, routing policies, and the cflowd tool on the 7705 SAR.
- Routing Protocols Guide
  This guide describes how to configure unicast routing protocols (OSFP, IS-IS, BGP, RIP) and multicast routing protocols (IGMP, MLD, PIM, MSDP) supported on the 7705 SAR.
- Services Guide
  This guide describes how to configure service parameters such as service access points (SAPs) and service destination points (SDPs), Layer 2 and Layer 3 services, security functions (IPSec), and encryption functions (NGE) on the 7705 SAR.
- System Management Guide
  This guide describes how to configure system security and access features, SNMP functionality, and event and accounting logs on the 7705 SAR.

802.1x tunneling and multihop MACsec

MACsec is an Ethernet packet and, as with any other Ethernet packet, can be forwarded through multiple switches using Layer 2 forwarding. The encryption and decryption of the packets is performed on 802.1x (MKA)-capable ports.

To ensure that MKA is not terminated on any intermediate switch or router, 802.1x tunneling can be enabled on the corresponding port using the config>port>ethernet>dot1x command. By enabling tunneling, the 802.1x MKA packets transit the port without being terminated. MKA negotiation does not occur on a port that has 802.1x tunneling enabled.

Note: If the intermediate port is enabled for both 802.1x tunneling and MACsec, MKA packets will still terminate on the node. However, if the port of the intermediate node is enabled only with 802.1x tunneling, the MKA packets will transit the node.

Use the info command to verify that 802.1x tunneling is enabled.
