2.10.17 Fast Ethernet Physical Interface Card for M-series Routers
The four-port Fast Ethernet Physical Interface Card (PIC) for M-series Internet
backbone routers provides economic 100-Mbps performance with high reliability
and low maintenance costs. The Fast Ethernet PIC is an attractive interface for a
variety of applications, including intra-POP switching, content Web hosting, and
both public and private peering.
Features
§ Wire-rate throughput on all ports at speeds up to 100 Mbps
§ Auto-senses full- and half-duplex modes
§ Supports large Ethernet frame sizes (up to 4,500 bytes)
§ Supports Virtual Router Redundancy Protocol (VRRP)
§ Supports 802.1Q Virtual LANs (VLANs)
§ RMON EtherStats

2.10.18 Gigabit Ethernet Physical Interface Cards for M-series Routers
The Gigabit Ethernet Physical Interface Card (PIC) provides the performance
needed for scaling POP infrastructures to support immense growth in
backbone capacity.
As the backbone scales, intra-POP connections between core routers and
access aggregation routers must also scale. The Gigabit Ethernet PIC
connects routers to intra-POP Gigabit Ethernet switches, enabling the
aggregation of large numbers of access circuits onto high-speed Internet
backbone circuits.
As backbone bandwidth scales to meet traffic demands, interconnects
between service providers at NAPs must also scale. The Gigabit Ethernet
PIC connects M-series routers to NAPS that are migrating to Gigabit
Ethernet as a shared medium.
With the Gigabit Ethernet PIC, the routers can support Web and content
hosting applications where traffic demands require Gigabit Ethernet up-links
from server farms. Combined with the wire-rate performance of M-series
routers, the Gigabit Ethernet PIC enables you to connect to an Internet
backbone circuit for faster Web response times.
Features
§ Wire-rate throughput on all ports at speeds up to 1 Gbps
§ Autonegotiation between Gigabit Ethernet circuit partners
§ Full-duplex mode
§ SX and LX optical interface support
§ Large MTUs of up to 9,192 bytes eliminates the need to do
fragmentation of packets larger than 1,500 bytes and enables you to
take advantage of the efficiencies of larger payload sizes
§ Virtual Router Redundancy Protocol (VRRP) support
§ 802.1Q Virtual LANs (VLANs) support
§ 32 source MAC address filters per port
§ 992 destination MAC filters per port
§ Packet buffering, Layer 2 parsing
§ RMON EtherStats
