• Large maximum transmission units (MTUs) of up to 9192 bytes

Software features

• Intelligent handling of oversubscribed traffic
• 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
• 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 hardware guide for your router.
• Duplex LC/PC connector (Rx and Tx)
• Fiber-optic small form-factor pluggable transceivers (SFPs):
  • 1000Base-LH (model number: SFP-1GE-LH)
  • 1000Base-LX (model number: SFP-1GE-LX)
  • 1000Base-SX (model number: SFP-1GE-SX)
  • 1000Base-T (model number: SFP-1-GE-T)

  Optical interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical Specifications

  Note: Do not install SONET/SDH SFPs in the Gigabit Ethernet port. The port will not recognize the SFP.

LEDs

OK LED, one tricolor:

• Off—PIC is offline and it is safe to remove it from the router.
• Green—PIC is operating normally.
• Yellow—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.
