Software release
  • JUNOS 6.0 and later
Description
  • One Gigabit Ethernet port
  • Power requirement: 0.46 A @ 48 V (22 W)
  • Intelligent queuing (IQ) PICs support fine-grained queuing per-logical interface.
Hardware features
  • High-performance throughput at speeds up to 1 Gbps
  • Full-duplex mode
  • Large MTUs of up to 9192 bytes
Software features
  • Optical diagnostics and related alarms (JUNOS Release 8.2 and later)
  • Quality of service (QoS) per channel: Weighted round-robin (WRR), Random early drop (RED), Weighted random early drop (WRED)
  • Virtual Router Redundancy Protocol (VRRP) support
  • 802.1Q Virtual LANs
  • VLAN stacking and rewriting
  • MAC policing, accounting, and filters
  • JUNOS Release 7.0 or later is required to configure graceful Routing Engine switchover (GRES).
Cables and connectors
  • The Gigabit Ethernet IQ PICs use small form factor-pluggables (SFPs) that allow different interfaces to be used on the PIC. For information about installing and removing SFPs, see the M20 Internet Router Hardware Guide.
  • SX, LX, and LH SFPs:
    • Duplex LC/PC connector (RX and TX)
    • Optical interface support—See Table 13
  • 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
  • Status LEDs, one tricolor:
    • Off—Not enabled
    • Green—Online with no alarms or failures
    • Amber—Online with alarms for remote failures
    • Red—Active with a local alarm; router has detected a failure
  • Port LEDs, one per port:
    • Off—Port is down
    • Green—Link is established
