Cisco 7600-ES20-10G3CXL designed for Carrier Ethernet, IP/MPLS PE Edge in mid-size and smaller service provider and enterprise WAN applications, the Cisco 7600 Series Ethernet Services 20G supports up to 20 Gbps of bandwidth. The cards feature hierarchical QoS, locally significant VLANs, and up to 32K VLAN IDs per line card for rich services at scale. These line cards provide the unique ability to combine both Layer 2 and Layer 3 services on the same line card. The combination of native Ethernet Layer 2 switching, bridging, VPLS, Ethernet over MPLS (EoMPLS), and Layer 3 IP/MPLS routing distinguishes this line card among other products on the market, particularly in Carrier Ethernet applications. The innovative architecture of these industry-leading, premium Ethernet services line cards is designed to deliver cost-effective high-touch features, combining both ASIC and Network Processor technology for an optimal combination of performance and flexibility. The cards provide distributed forwarding with proven ASIC technology in the forwarding path (routing, switching, Netflow, ACLs), as well as for queuing and shaping functions to provide the maximum performance for these foundational features. Additionally, two programmable network processors are included in the forwarding plane to facilitate flexibility a(more...)
Introduction to the Cisco 7600 Series Ethernet Services 20G Line Card
The Cisco 7600 Series Ethernet Services 20G (ES20) line cards are a multiple-fabric, fixed-port Ethernet line card for the Cisco 7600 series routers that are capable of 20 Gbps of traffic forwarding using a fixed port interface design. The two versions of the Cisco 7600 Series Ethernet Services 20G line card are:
•2-port version: 7600-ES20-10G
•20-port version: 7600-ES20-GE
The difference between the two versions are the link interface daughter cards that accept small form-factor pluggable (SFP or XFP1 ) optical transceivers. Additionally, each of the two versions has a packet engine daughter card and a control processor daughter card.
The SFP and XFP modules allow the line cards to be configured for different media types (copper or fiber) and different optical requirements (single mode fiber or multimode fiber) as available.
The 7600-ES20-10G uses a 2-port 10GE fixed interface daughter card that accepts pluggable XFP modules.
The 7600-ES20-GE uses a 20-port GE fixed interface daughter card that accepts pluggable SFP modules.
The Cisco 7600 Series Ethernet Services 20G line cards have the following features:
•Large output buffers to prevent spurious packet loss. These output buffers provide up to 200 milliseconds (ms) of round-trip time buffer at an aggregate bandwidth of 10 Gbps
•Up to 8,000 queues per port, 16,000 queues total, for combined input and output queueing and scheduling
•The PXF processor provides programmable ingress and egress feature processing capability.
•NT3PE-500 with 128MB reduced latency DRAM (RLDRAM) per column
•40+ Mpps Layer3/Layer4 forwarding, 125 Mpps Layer 2 forwarding
•Dual fabric attachment providing an aggregate bandwidth of 40 GBs, full duplex (each fabric channel provides 20 GBs full duplex)
Cisco 7600 Series Ethernet Services 20G Line Card Product Numbers
Table 1-1 lists the Cisco product numbers for the line cards.
Table 1-1 Cisco 7600 ES20 Line Card Product Numbers
Cisco Product Number
Field-Replaceable Unit (FRU) Product ID
Cisco 7600 ES20 line card, 20xGE SFP with DFC 3C
Cisco 7600 ES20 line card, 20xGE SFP with DFC 3CXL
Cisco 7600 ES20 line card, 2x10GE XFP with DFC 3C
Cisco 7600 ES20 line card, 2x10GE XFP with DFC 3CXL
Note The Distributed Forwarding Card (DFC) on a7600-ES20-GE will function at the lowest common denominator with the rest of the system. Therefore if a 7600-ES20-GE with a DFC 3CXL is configured in a system with the PFC3BXL present, then the system will function only at the 3BXL level.
Similarly, if a DFC 3CXL is configured on a different line card then the system would function at the 3BXL level regardless of other 3CXL ASICs installed in the system.
