Documentation Updates

This section lists the errata and changes in Junos OS Release 16.1R1 documentation for MX Series.

Security Services Administration Guide

  • The “Distributed Denial-of-Service (DDoS) Protection Overview” topic has been updated to describe the built-in login overload protection mechanism that is available on MX Series routers.

    The login overload protection mechanism (also called a load-throttling mechanism) monitors the incoming subscriber login packets and admits only what the system is capable of handling in accordance with the prevailing load on the system. Packets in excess of what the system can handle are discarded. By shedding this excess load, the system is able to maintain optimal performance and prevent any degradation of login-completion rate under overload conditions. This mechanism uses minimal resources and is enabled by default; no user configuration is required.

    The protection provided by this mechanism is secondary to what distributed denial-of-service (DDoS) protection provides as a first level of defense against high rates of incoming packets. DDoS protection operates on the Packet Forwarding Engine and protects against all packet types of all protocols. In contrast, the login overload protection mechanism is located on the Routing Engine and specifically operates only on incoming connection-initiation packets such as DHCPv4 DHCPDISCOVER, DHCPv6 SOLICIT, and PPPoE PADI packets.

SNMP MIBS and traps reference

  • SNMP MIBs and Traps Reference deprecation—Starting in Junos OS Release 16.1, the SNMP MIBs and Traps Reference has been deprecated. To access information about SNMP MIB objects, tables, and notifications, use the SNMP MIB Explorer. For an overview of the MIBS supported on Junos OS, see the Network Management Administration Guide.

Syslog Reference Guide

  • System Log Messages Reference deprecation—Starting in Junos OS Release 16.1, the System Log Messages Reference has been deprecated. To access information about system log messages, use the System Log Explorer or continue to use the CLI by executing the ‘help syslog <tag> command, where the tag is the unique identifier of the error message. For an overview of system log messages, see System Log Messages Configuration Guide.

Standards Reference

  • The Supported Network Management Standards topic incorrectly states that Junos OS supports mplsL3VpnIfConfTable as part of compliance with RFC 4382, MPLS/BGP Layer 3 Virtual Private Network (VPN) MIB. Junos OS does not support this table.
