Ethernet Operation
The Cisco ONS 15454 integrates Ethernet into a SONET time-division multiplexing (TDM) platform.
The ONS 15454 supports both E series Ethernet cards and the G series Ethernet card. This chapter
describes the Ethernet capabilities of the ONS 15454, including:
• G Series Card (G1000-4)
– 802.3x flow control and frame buffering
– End-to-end link integrity and Gigabit EtherChannel
– GBICs
– Ethernet circuit provisioning
– Ethernet performance and maintenance screens
– Ethernet alarm thresholds (RMON)
• E Series Cards
– E100T-12/E100T-G cards
– E1000-2/E1000-2-G cards
– GBICs
– Multicard and Single-card Etherswitch
– Ethernet circuit combinations, configurations and provisioning
– VLAN and IEEE 802.1Q support
– Spanning tree and IEEE 802.1D support
– Ethernet performance and maintenance screens
– Ethernet alarm thresholds (RMON)
9.1 G1000-4 Card
The G1000-4 card reliably transports Ethernet and IP data across a SONET backbone. The G1000-4 card
maps up to four gigabit Ethernet interfaces onto a SONET transport network. A single card provides
scalable and provisionable transport bandwidth at the signal levels up to STS-48c per card. The card
provides line rate forwarding for all Ethernet frames (unicast, multicast, and broadcast) and can be
configured to support Jumbo frames (defined as a maximum of 10,000 bytes).The G-series card
incorporates features optimized for carrier-class applications such as:
