To Know about the New 32-port 10-Gb Line Cards on Catalyst 6800 &6500-E Series

Gigabit Ethernet modules play a vital role on in Cisco’s campus aggregation and core switches. Recently, Cisco released several new 32-port 10-Gb line cards on Cisco Catalyst 6800 and 6500-E Series Switches that help you make the transition from 1 Gigabit to 10 Gigabits, and allow for twice the 10-Gb density. These Gigabit Ethernet modules provide rich network services that you have come to expect from these platforms. And flexibility is built in so you can convert to 40-Gigabit speeds in future.

The Cisco Catalyst 6800 Family Switches offer a variety of 10-Gigabit Ethernet modules. Working in conjunction with the Catalyst 6500-E/6807-XL Supervisor Engine 2T/2TXL (VS-S2T-10G & VS-S2T-10GXL), they can serve different needs on campus deployments. The family includes three modules: the Catalyst 6800 32-port, 16-port, and 8-port 10-Gigabit Ethernet Fiber Modules.

The modules support hardware-based multicast replication, quality of service (QoS), access control lists (ACLs), jumbo frames, and low latency to enable secure and predictable performance for bandwidth-intensive applications. All three share a common ASIC architecture and support the same set of features in hardware. They support Small Form-Factor Pluggable (SFP/SFP+), 10/100/1000M GLC-T (1G copper SFP) transceivers, and 100M FX. The modules are designed to meet the increasing demand for aggregation of 10-Gigabit Ethernet streams in campus deployments, as well as for high-density 10-Gigabit Ethernet transport in the core.

The modules consist of port groups of eight ports each. The 32-port and 16-port modules can operate in either of two modes: 1) oversubscribed mode (default), which provides for maximum port density, using all of the ports with 2:1 oversubscription; and 2) performance mode, which uses half of the ports, enabling line rates and double the port buffer size. The mode of operation can be changed for each eight-port port-group (mixed mode), and is described in more detail in the following sections. The eight-port 10-Gigabit Ethernet Module always operates in performance mode.

The modules are based on the WS-X6904-40G module and provide the same level of advanced enterprise features and large table sizes that have proven essential to successful operation as a campus aggregation or core switch. They include hardware features such as Virtual Switching System (VSS), Instant Access (IA), Location ID Separation Protocol (LISP), Security Group Tagging (SGT) and Access Control (SGACL), MACsec (802.1ae), traffic shaping, and hierarchical quality of service (HQoS), among others.

Performance Mode

Cisco Catalyst 6800 Family 32-Port and 16-Port 10-Gigabit Ethernet Fiber Module can operate in performance mode to provide line-rate operation. The 8-Port 10-Gigabit Ethernet Fiber Module provides line rate by default, so there is no performance mode for the eight-port module.

In performance mode, a set of eight ports is grouped as a port-group. Performance mode enables line-rate performance by using half (4) of the ports in each port-group. Oversubscribed mode uses all eight ports in a port group and provides 2:1 oversubscription. Details for the default mode and performance mode are shown in Figure 4 and the description below it.

6800 Family 32-Port 10-Gigabit Ethernet Fiber Module Port Groups and Performance Mode

●Oversubscribed mode (default)

  1. ◦For the 32-Port 10-Gigabit Ethernet Module, ports are numbered from left to right. As shown, the top row has odd number ports and the bottom row has even number ports.
  2. ◦For the 16-Port 10-gigabit Ethernet Module. ports are numbered from left to right.

●Performance Mode

  1. ◦In performance mode, the second four ports in each port group operate in shutdown mode.
  2. ◦The first half of the ports can achieve line rate
  3. ◦The ingress and egress buffer sizes are also doubled

Note: When the 32-Port 10-Gigabit Ethernet Fiber Module is operating in the Catalyst 6500-E chassis, the oversubscription mode is 4:1 and the performance mode is 2:1.
