Introduction to the Cisco 7600 ES+ and ES+ Combo Low Queue Line Cards
The Cisco 7600 Series ES+ line cards are a multiple-fabric, fixed-port Ethernet line card for the Cisco 7600 series routers that are capable of 40 gbps full-duplex traffic forwarding using a fixed port interface design. The Cisco 7600 Series ES+ line card versions are:

The difference between the 7600-ES+20G3CXL思科原装线卡模块versions are the link interface daughter cards that accept small form-factor pluggable (SFP, SFP+, or XFP1 ) optical transceivers. Additionally, each of the versions has a common baseboard card and a control processor daughter card, except for the 8 port version (76-ES+T-8TG) which has a different baseboard.
The SFP, 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.7600-ES+20G3CXL思科原装线卡模块
See Table 1-4 for information about which SFPs, SFP+, or XFPs are accepted on the different Cisco 7600 Series ES+ line cards.
Product Overview
7600-ES+20G3CXL思科原装线卡模块

The Cisco 7600 Series ES+ line cards have the following features:
The system features listed here specify some of the key performance metrics and capabilities of the line cards. The information below applies to all four line cards unless stated otherwise.
•Line rate feature processing performance with 64 byte packets for four ports of 10 GE or forty ports of GE (59.52Mpps). Note that the line card throughput is limited by the system switch fabric. The packet processor and internal sections of the line card are full line rate throughput capable for 40GbE.
7600-ES+20G3CXL思科原装线卡模块

•Large output buffers provide up to 200 mS of round-trip-time buffer (100 mS in each direction) per 10GE port or 10xGE ports to prevent transient output overloads from causing spurious packet loss.
•Up to 32K queues (per 10GE port or 10xGE ports) per direction for input or output queuing and scheduling.
•Programmable ingress and egress feature processing capability through the Trident.
•40+ Mpps Layer 3 or Layer 4 forwarding, 125Mpps Layer 2 forwarding.
•Dual fabric attachment providing an aggregate bandwidth of 40Gb/s, full duplex (each fabric channel provides 20Gb/s, full duplex).
•512-MB boot disk

Note The Distributed Forwarding Card (DFC) on a 7600 ES+ line card functions at the level of the lowest common denominator DFC in the system. If the only DFC in a system is a DFC 3CXL, then the system would operate at the 3CXL level. If a DFC 3CXL is configured in a system with a DFC3BXL present, then the system will function at the DFC 3BXL level. Additionally, a DFC 3CXL provides for more TCAM entries than does a DFC 3C.  7600-ES+20G3CXL思科原装线卡模块

Cisco IOS Software Release and Hardware Revision Requirements
The Cisco 7600 ES+ line cards have certain Cisco IOS software requirements. Also, to ensure compatibility with the software, your Cisco 7600 ES+ line card should have a specific hardware revision number. The number is printed on a label affixed to the component side of the card and is displayed by the show diag command.
Table 1-3 lists the hardware and software requirements for Cisco 7600 ES+ line cards.

The show diag slot_number, show version, and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running, and the hardware revision number. For complete descriptions of show commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference for the installed Cisco IOS release.
If the command displays indicate that the Cisco IOS software is a version earlier than you need, check the contents of flash memory to determine if the required images are available on your system. The dir devicename command displays a list of all files stored in flash memory. If you do not have the correct software version, contact Cisco customer service.
For software configuration information, refer to the Cisco IOS software configuration and command reference publications for the installed Cisco IOS release. Also refer to the Cisco IOS software release notes for additional information.
Modular Optics Compatibility
The Cisco 7600 Series ES+ line cards use small form-factor pluggable (SFP, SFP+, or XFP) optical transceivers to provide network connectivity. Table 1-4 provides links to tables showing the supported modules for the different Cisco 7600 Series ES+ line cards.
