ML-Series Feature List
The ML100T-12, ML100X-8, and ML1000-2 cards have the following features:
• Layer 1 data features:
– 10/100BASE-TX half-duplex and full-duplex data transmission
– 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 Ethernet) 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.
