Fact Sheet

Cisco 12000 Series Four-Port OC-12c/STM-4c ATM Line Card

The Cisco 12000 series four-port OC-12c/STM-4c ATM line card complements the existing suite of ATM line cards for the Cisco 12000 series router product line, providing increased port density while delivering high-performance packet forwarding. The primary use of this card is for backbone applications. The new line card performs the segmentation and reassembly (SAR) of IP packets in accordance with RFC 1483, Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5).

Feature Summary

Packet Layer

  • 2.8-Mpps IP forwarding rate (bidirectional OC-12 line rate for 64 byte packets on all four ports)
  • Cisco Express Forwarding (CEF) table that can accommodate up to one million of forwarding entries
  • Interleaved IP Version 4 (IPv4) and MPLS (Tag Switching) packets
  • Buffering up to 128 MB in both Tx and Rx directions
  • Class of service (CoS) of up to eight levels per output port using modified deficit round robin (MDRR)
  • Random early detection (RED) on all output queues
  • Weighted random early detection (WRED) (per port)
  • IP and Multiprotocol Label Switching (MPLS) load balancing for up to six paths
  • Packet/byte count, SONET/SDH errors, queue size, and WRED statistics (per port)
  • Multicast forwarding
  • Maximum transfer unit (MTU) of 9188 bytes
  • 64 MB of route table memory, expandable to 256 MB
  • 256 MB of packet buffer memory, expandable to 512 MB

ATM Layer

  • Unspecified bit rate (UBR) traffic class, simple first-in, first-out (FIFO) queuing
  • RFC 1577 classical IP over ATM
  • RFC 1483 Multiprotocol Encapsulation over AAL5
  • ATM AAL5
  • UNI 3.0 and 3.1 (including ILMI)
  • OAM F5
  • Support for up to 2047 VCs per port
  • Per-VC accounting for both transmitted and received packets
  • Per-port ATM layer dropped packets and CRC error counting
  • Support for 227 simultaneous resembles per port at a 9 KB maximum transmission unit (MTU) size
  • NLPID encapsulation
  • Flexible VP number assignment

SONET/SDH Layer

  • Standards-compliant Synchronous Optical Networking/Synchronous Digital Hierarchy (SONET/SDH) interface
  • Alarm processing, which includes loss of signal (LoS), loss of frame (LoF), line alarm indicator signal (LAIS), path alarm indicator signal (PAIS), loss of pointer (LOP), line remote defect indicator (LRDI), path remote defect indicator (PRDI), signal failure (SF), signal degrade (SD), line remote error indicator (Line REI), path remote error indicator (Path REI)
  • Synchronization, which includes local (internal) or loop timed (recovered from network), 20 ppm clock accuracy over full operating temperature range, and pointer activity monitoring
  • Local (diagnostic) and line (network) loopback
