Hardware features | - High-performance throughput: speeds up to 1 Gbps on each
port
- Full-duplex mode
- Large maximum transmission units (MTUs) of up to 9192
bytes
|
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)
- Drop statistics reported per queue for each of four priority-based
drop profiles
- Four levels of strict priorities with priority propagation
among scheduling levels
- Hierarchical shaping and hierarchical scheduler
- Virtual Router Redundancy Protocol (VRRP) support
- 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
- 16,000 schedulers (2,000 schedulers with 8 queues each
or 4,000 schedulers with 4 queues each)
- Scheduler resources dynamically allocated across ports
- Flexible Ethernet encapsulation
- MAC learning, policing, accounting, and filtering

Cables and connectors | |
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.
- 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.
