Juniper Networks M120 manual Hierarchical shaping

M120 Internet Router PIC Guide

Software features	■	Intelligent handling of oversubscribed traffic for Type 1 and Type 2 PICs
	■ Optical diagnostics and related alarms
	■ Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection
		(RED), weighted random early detection (WRED)
	■ Virtual Router Redundancy Protocol (VRRP) support
	■	Hierarchical shaping
	■ Fine-grained queuing and shaping per logical interface at both ingress and egress
	■ 802.1q virtual LANs (VLANs)
	■ VLAN stacking and rewriting
	■ Channels defined by two stacked VLAN tags
	■ Point-to-Point Protocol over Ethernet (PPPoE) over VLAN (JUNOS Release 8.5 and later.)
	■ Multiple tag protocol identifiers (TPID) support
	■ IP service for nonstandard TPID and stacked VLAN tags
	■ 802.1p rewrite per channel
	■ Flexible mapping of channels and scheduler resources at both ingress and egress
	■	Flexible Ethernet encapsulation
	■ MAC learning, policing, accounting, and filtering
Cables and connectors	■	You can install any transceiver supported by the PIC. For information about installing
		and removing transceivers, see the PIC and Transceiver Installation Instructions.
	NOTE: Do not install SONET/SDH SFPs in the Gigabit Ethernet port. The port will not recognize
	the SFP.
	■ Fiber-optic small form-factor pluggable transceivers (SFPs):
		■ Duplex LC/PC connector (Rx and Tx)
		■ Optical interface support—See Table 17 on page 69
	■	Copper 1000Base-T SFPs:
		■ Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45
		connector
		■ Pinout: MDI crossover
		■ Length: 328 ft/100 m
LEDs	OK or Status LED, one tricolor:
	■ Off—PIC is offline and it is safe to remove it from the router.

■ Green—PIC is operating normally. ■ Amber—PIC is initializing.

■ Red—PIC has an error or failure.

APP LED, one bicolor:

■Off—Monitoring application is not running.

■Green—Monitoring application is running under acceptable load.

Port LEDs, one per port:

■Off—Port is not enabled.

■Green—Port is online with no alarms or failures.
