ML-Series Feature List
The ML100T-12, ML100X-8, and ML1000-2 cards have the following features:
Layer 1 data features:

100BASE-FX full-duplex data transmission with Auto-MDIX (ML100X-8)
1000BASE-SX, 1000BASE-LX full-duplex data transmission
IEEE 802.3z (Gigabit Ethernet) and IEEE 802.3x (Fast Ethe rnet) Flow Control
SONET/SDH features:
High-level data link control (HDLC) or frame-mapped generic framing procedure (GFP-F)
framing mechanism for POS
Two POS virtual ports
LEX, Cisco HDLC, or Point-to-Point Protocol/Bridging Control Protocol (PPP/BCP)
encapsulation for POS
VCAT with SW-LCAS
G-Series card and ONS 15327 E-Series card compatible (with LEX encapsulation only)
Layer 2 bridging features:
Transparent bridging
MAC address learning, aging, and switching by hardware
Protocol tunneling
Multiple Spanning Tree (MST) protocol tunneling
255 active bridge group maximum
60,000 MAC address maximum per card and 8,000 MAC address maximum per bridge group
Integrated routing and bridging (IRB)
IEEE 802.1P/Q-based VLAN trunking
IEEE 802.1Q VLAN tunneling
IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1W Rapid Spanning Tree Protocol
(RSTP)
IEEE 802.1D STP instance per bridge group
Ethernet over Multiprotocol Label Switching (EoMPLS)
EoMPLS traffic engineering (EoMPLS-TE) with RSVP
VLAN-transparent and VLAN-specific services (Ethernet Relay Multipoint Service [ERMS])
RPR-IEEE data path features supported:
Bridging is supported, as specified in the IEEE 802.17b spatially aware sublayer amendment.
Shortest path forwarding through topology discovery is supported.
Addressing is supported, including unicast, multicast, and simple broadcast data transfers.
Bidirectional multicast frames flood around the ring using both east and west ringlets.
The time to live (TTL) of the multicast frames is set to the equidistant span in a closed ring and
the failed span in an open ring.
