NETSCREEN-SCHEDULE-MIB

Description: Manages time-based schedule objects used by firewall policies and VPN rules on Juniper NetScreen devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

NETSCREEN-SCHEDULE-MIB is a Juniper NetScreen private MIB (from the NetScreen firewall/VPN line later absorbed into Juniper ScreenOS) that manages time-based schedule objects used by firewall policies and VPN rules to activate or deactivate at specific times. It exposes configuration data describing one-time schedules (name, start time, stop time, comments) and recurring schedules, each optionally scoped to a virtual system (vsys) in a multi-tenant firewall deployment. Rather than hardware health, this is a configuration/software-state MIB: it lets an administrator confirm which named schedules exist, their active windows, and which virtual system they belong to, essential for auditing why a firewall policy is or isn't currently in effect. It sits within the broader NetScreen/ScreenOS private MIB tree alongside firewall-policy MIBs, since schedules are referenced by policy objects elsewhere. It is deployed on Juniper NetScreen (ScreenOS) firewalls/VPN gateways in enterprise perimeter security deployments, especially those using virtual systems. Engineers can download the NETSCREEN-SCHEDULE-MIB file directly to load it into their MIB browser.

An administrator would poll the nsSchOnceTable/nsSchOnceEntry rows, indexed by nsSchOnceIndex, to check nsSchOnceName against nsSchOnceStartTime and nsSchOnceStopTime, confirming whether a maintenance-window firewall rule is currently active. Similarly, the nsSchRecurTable/nsSchRecurEntry rows (indexed by nsSchRecurIndex, named via nsSchRecurName) let the admin verify a recurring schedule, such as a nightly VPN policy window, is correctly defined. If nsSchOnceVsys shows a schedule scoped to the wrong virtual system, that would explain a firewall policy unexpectedly failing to activate for a particular tenant.
