What’s Changed

In order to monitor vmhost storage usage:

A new minor alarm, VMHost RE 0 Disk 1 inode usage breached threshold is introduced. The existing minor alarm, VMHost RE 0 Disk 1 Usage is above threshold is changed to VMHost RE 0 Disk 1 Size usage breached threshold.

PTP configuration might not function correctly on an MX10008 Router with JNP10K-LC2101 Line card: - when Hypermode is enabled. Hypermode can be enabled by default when MX10008 Router has Switch Fabric Board 2 (SFB2), or by using the command set forwarding-options hyper mode. Hence, such PTP interfaces (slave, master, stateful) are unsupported. - if an aggregated Ethernet (AE) interface is configured and either the primary or secondary links on the AE do not support PTP with Hypermode, then the whole AE is marked as unsupported.

An optics configuration mismatch alarm may be triggered when there is a discrepancy between the configured speed of an interface and the supported speed of the optic. This alarm indicates that the optic installed in the specified FPC is incompatible with the speed configured on the interface.

Change the output of the show arp command to display IP addresses and hostnames (MX Series routers)—You can force the show arp command output to display the IP address next to the hostname of each device. To do this, enable the force-show-arp-resolve statement at the [edit system services subscriber-management overrides] hierarchy level. This makes it easier to manage subscriber access if your subscriber configuration relies on the IP addresses of the devices.

Support for the junos:cli-feature YANG extension (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The cli-feature YANG extension identifies certain CLI properties associated with some command options and configuration statements. The Junos YANG modules that define the configuration or RPCs include the cli-feature extension statement, where appropriate, in schemas emitted with extensions. This extension is beneficial when a client consumes YANG data models, but for certain workflows, the client needs to generate CLI-based tools.

[See Understanding the Junos DDL Extensions YANG Module.]

New options for the request system snapshot command (ACX Series, EX Series, MX Series, PTX Series, QFX Series, and SRX Series)—The request system snapshot command includes new options for non-recovery snapshots. You can include the name option to specify a user-defined name for the snapshot, and you can include the configuration or no-configuration option to include or exclude configuration files in the snapshot. By default, the snapshot saves the configuration files, which include the contents of the /config and /var directories and certain SSH files.

[See request system snapshot (Junos OS with Upgraded FreeBSD).]

The file copy command supports only text-formatted output in the CLI (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The file copy command does not emit output when the operation is successful and supports only text-formatted output when an error occurs. The file copy command does not support using the | display xml filter or the | display json filter to display command output in XML or JSON format in any release. We've removed these options from the CLI.
