Network Management and Monitoring

  • Operational command RPCs support returning JSON and XML output in minified format in NETCONF sessions (ACX1000, ACX1100, ACX2100, ACX4000, ACX5048, ACX5096, ACX5448, EX2300, EX3400, EX4300, EX4400-24P, EX4400-24T, EX4400-48F, EX4400-48P, EX4400-48T, EX4600, EX4650, EX9200, MX104, MX204, MX240, MX480, MX960, MX2008, MX2010, MX2020, MX10003, MX10008, MX10016, PTX1000, PTX5000, PTX10001, PTX10002, PTX10008, PTX10016, QFX5100, QFX5110, QFX5120, QFX5200, QFX5210, QFX10002, QFX10002-60C, QFX10008, QFX10016, SRX550HM, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, SRX5800, vMX, and vSRX)—Starting in Junos OS Release 21.1R1, operational command RPCs, including the <get-configuration> RPC, support the format="json-minified" and format="xml-minified" attributes in NETCONF sessions to return JSON or XML output in minified format. Minified format removes any characters that are not required for computer processing—for example, unnecessary spaces, tabs, and newlines. Minified format decreases the size of the data, and as a result, can reduce transport costs as well as data delivery and processing times.

  • sFlow support for IP-IP traffic (PTX1000, PTX10008, and QFX10002)—Starting in Junos OS Release 21.1R1, you can use sFlow technology to sample IP over IP (IP-IP) traffic on a physical port. sFlow sampling is supported for IP-IP tunnels that have an IPv4 outer header that carry IPv4 or IPv6 traffic. You can use sFlow monitoring technology to randomly sample network packets from IP-IP tunnels and to send the samples to a destination collector for monitoring. Devices that act as an IP-IP tunnel entry point, transit device, or tunnel endpoint support sFlow sampling.

  • Remote port mirroring to IPv6 address (GRE encapsulation)( EX4650, EX4650-48Y-VC, QFX5120, QFX5120-32C, QFX511120-48T, QFX5120-48T-VC, QFX5120-48Y, and QFX5120-48YM)—Starting in Junos OS Release 21.1R1, you can use remote port mirroring to copy packets entering a port or VLAN and sends the copies to the IPv6 address of a device running an analyzer application on a remote network (sometimes referred to as “extended port mirroring”). When you use remote port mirroring the mirrored packets are GRE-encapsulated.

    Add the address you would like to have the copied packets sent to in the CLI hierarchy. For example, set forwarding-options analyzer ff output ipv6-address 2000::1.
