Product
Description: The Cisco Systems WS-X6716-10G-3CXL is
a Catalyst 6500 Series 16-Port 10 Gigabit Ethernet network
module. This network module doubles the 10 Gigabit Ethernet
density of the Cisco Catalyst 6500 Series, and this module
has double the ports that a Cisco WS-X6708-10G-3CXL has.
The WS-X6716-10G-3CXL is perfect for installation in the
LAN (Local Area Network) campus aggregation or data center
access setups, where the strength of bandwidth, port density,
and fan out are all of high significance in this network
platform.
This module then allows customers to design
and build a strong, scalable, and easy-to-manage data
center to converge on the expanding business needs of
wireless applications and broadband video. The WS-X6716-10G-3CXL
allows for software virtual servers and storage to get
the most usage out of the resources available as well
as reducing overall cost.
There are 2 different versions of the Cisco Systems Catalyst
6500 Series WS-X6716-10G cards. There is the DFC3C distributed
forwarding card 3C, and the DFC3CXL distributed forwarding
card DFC3CXL. They both have 16 Ports, and both network
modules include the WS-X6716-10GE base board with a distributed
forwarding card. The base board that is similar to both
the WS-X6716-10G-3C and the WS-X6716-10g-3CXL maintains
up to 16 pluggable X2 Optics, like the X2-10GB-LR, and
the Cisco X2-10GB-SR, and the board has a 40-Gbps (Gigabit
per second) connection to the fabric board and is also
4:1 oversubscribed.
For both the WS-X6716-10G-3C and WS-X6716-10G-3CXL, the
distributed forwarding card gives hardware-based multicast
duplication, Cisco NetFlow, and MAC address learning.
Also, it forwards IP traffic at 48 Mpps (Million packets
per second). In addition to the advance in port strength,
the WS-X6716-10G-3C also has a decreased power consumption,
resulting again in lower overall operating costs. In actuality,
these network modules use only ½ of the power usage
per port as opposed to the 8-port 10 Gigabit Ethernet
module. This gives enormous potential power savings at
the end users’ side of the network. There are several
different modes that the WS-X6716-10G-3CXL can operate
in, allowing for an array of customer options in connecting
and deployment of their network. Customers can assign
some ports to servers, while others can be for wiring
closet uplinks. When the module is in operational mode,
the 10 Gigabit Ethernet ports are also able to make a
virtual switch link in a Cisco Catalyst 6500 Series VSS
(Virtual Switching System) software configuration.
There are only a few differences between the WS-X6716-10G-3C,
which utilizes the DFC3C Distribution Forwarding Card
daughter card, and the WS-X6716-10G-3CXL, which utilizes
the DFC3CXL Distribution Forwarding Card daughter card.
First of all, the IPv4 routes able are 256,000 on the
DFC3C card, and 1 million routes on the DFC3CXL –
more than 3 times the amount of IPv4 routes. For IPv6
routes, the DFC3C has 128,000 routes, and the DFC3CXL
has 500,000 routes. The amount of NetFlow Entries is 128,000
for the 10G-3C, and 256,000 for the 10G-3CXL. For Access
Control Lists (ACLs), the results are quite similar: 128,000
for the 10G-3C, and 256,000 for the 10G-3CXL. The module
itself is supported in the Cisco Catalyst 6500 Series
chassis. The NEBS 3 configuration is completely compliant
when utilizing the WS-X6716-10G-3CXL in an E-Series Chassis,
like the Cisco 6503-E, or the 6504-E, or the 6506-E, the
6509-E, or the 6509-V-E. Also, it supports temperatures
up to 55° Celsius. If the module is operating in a
non-E Series chassis, as with the Cisco 6506, Cisco 6509,
Cisco 6513, or 6509-NEB-A, the configuration is not NEBS
3 compliant.
Interestingly, the WS-X6716-10G-3CXL is able to be deployed
in all slots of a 3,4,6, or 9 slot chassis. However, in
a Cisco 13-slot chassis, like the Cisco WS-C6513, the
network module has to be installed in slots 9 through
13. It isn’t supported in the 6503 and non-E Series
chassis or Cisco 7600 Series Routers. The Cisco WS-X6716-10G-3CXL
works in all models of the Cisco Catalyst 6500 Series
VSS Engine 720 with 10 Gigabit Ethernet uplinks or Cisco
Catalyst 6500 Series Supervisor Engine 720. Of note, when
switching or swapping the Distributed Forwarding Cards
in the same 6500 Series chassis, this chassis will function
in the mode of the lowest common denominator of the two.
For example, if a 3C DFC is working, then the switch using
VSS will operate and function with the 3C DFC capabilities.
At this point, the X2 fiber optics that are supported
on the 16-port 10 Gigabit Ethernet module are: the Cisco
X2-10GB-LRM, the Cisco X2-10GB-SR, the Cisco X2-10GB-LR,
the Cisco X2-10GB-ER, the Cisco X2-10GB-LX4, and the Cisco
X2-10GB-CX4 optics. In order to qualify for EMI compliance,
SR and CX4 optics require version -02 or above; ER needs
version -03 or above; LR and LX4 need version -04 or above,
and there is no limitation on the LRM optic. Also, the
LRM optics give 220m over multi-mode fiber and are perfect
for installation in campus LAN (Local Area Network) uplink
ports and in data centers.
The Cisco IOS Software and Cisco IOS Software Modularity
Release 12.2(33)SXH2 or later supports both versions of
the 16-port module. Both the WS-X6716-10G-3C and WS-X6716-10G-3CXL
have complete support with IOS 12.2(33)SXH2. Over time,
Cisco Systems will release more fiber optic transceivers,
and they will issue a list of the latest supported fiber
optic transceivers.
The exact part number for the WS-X6716-10G-3CXL is the
Cisco WS-F6700-DFC3CXL, and for the WS-X6716-10G-3C is
the Cisco WS-F6700-DFC3C. However, both 16-port network
modules require X2 optics to be populated in it. There
are currently 6 fiber optics that are operational with
the WS-X6716 network modules. The X2-10GB-LRM is an X2
optic that has a range of 220 meters over multimode fiber.
The Cisco X2-10GB-SR supports 26m over FDDI grade multimode
fiber and 300m over 50um 2000 MHz km multimode fiber.
On the Cisco X2-10GB-LR, the distance range is 10 kilometers
over single mode fiber. The X2-10GB-ER extends the range
to 40 kilometers over single mode fiber. The X2-10GB-LX4
supports 300m over multimode fiber, and the X2-10GB-CX4
supports 15 meter over copper InfiniB and cable. Specialized
cabling is required for the CX4 fiber optic transceiver.
The cables for the CX4 transceiver range from 1 to 5 to
10 and 15 meters in patch cables for the CX4 XENPAK module.
The part numbers for the cables are: CAB-INF-28G-1 for
the 1 meter patch cable and using the XENPAK-10GB-CX4
module, CAB-INF-28G-5 for the 5 meter patch cable, CAB-INF-28G-10
for the 10 meter cable, and finally CAB-INF-28G-15 for
the 15 meter cable. All of these cables mentioned above
must use the CX4 module in conjunction with these cables.
MAIN BENEFITS AND FUNCTIONS
“Double Density” is the primary benefit of
the WS-X6716-10G-3C and WS-X6716-3CXL network modules.
The Cisco Catalyst 6500 Series 16-port 10 Gigabit Ethernet
module doubles the 10 Gigabit Ethernet port density supported
on a Cisco Catalyst 6500 Series Switch, now giving up
to 132 of 10 Gigabit Ethernet ports per chassis, or up
to 264 10 Gigabit Ethernet ports per VSS (Virtual Switching
System). Also, along with dual strength, the WS-X6716-10G-3CXL
has decreased power usage and utilizes only half the power
consumption when being compared to the 8-port 10 Gigabit
Ethernet module.
There are 2 modes of operation for both the WS-X6716-10G-3CXL
and the WS-X6716-10G-3C, which are oversubscription mode
or performance mode. This allows for maximum elasticity
in that customers can now choose to connect up some of
their ports to servers and some of their ports to wiring
closet uplink ports. Also, when the network modules are
utilized in a 6500 Catalyst E-Series switch chassis, both
the 8-port and the 16-port modules support fast switch
fabric fail-over time of less than 50 mili-seconds, which
improves the network’s high availability.
The differences between the “oversubscription mode”
and “performance mode” for the WS-X6716-10G-3CXL
and 3C basically come to higher, reliable performance
versus tons of users in need of bandwidth, and thus the
need for all to be subscribed. Below, we describe how
to enable each mode. The default, standard mode for the
WS-X6716-10G-3CXL and 3C is “oversubscription mode”
and users can change the mode to performance mode by software
commands via telnet in the DB9 or USB ports depending
on the type of adapter that you are using. The 16-port
module divides up into 4 separate port groups. Port Group
1 is ports 1 through 4, and port 1 is automatically enabled
in performance mode. Port Group 2 is ports 5 through 8,
and port 5 is enabled in performance mode. Port Group
3 is ports 9 through 12, and port 9 is enabled in performance
mode. And Port Group 4 is ports 13 through 16, and port
13 is enabled in performance mode.
Each individual port group of 4 ports can function in
either the performance mode or the oversubscription mode.
In oversubscription mode, the network administrator can
take full advantage of all ports in the port group. However,
in performance mode, the only enabled and live port is
the first port in the port group, to a maximum of 4 ports.
In performance mode, the benefit is enhanced buffering
and quality-of-service (QoS) operations. With performance
mode enabled, the remaining 3 ports in the port group
are administratively shut down.
An example of how to switch from oversubscription mode
from performance mode is below. The software command when
connected administratively to the switch is “router(config)#[no]
hw-module slot x oversubscription port-group y”
will put port group y, which is ports 1 through 4 in performance
mode and override and disable the oversubscribed ports,
which would be all remaining ports that are not the first
in their port group. In performance mode, the network
technician can perform a “no shut” command
on the disabled ports. The configuration in Hyper terminal
or a different telnet program would look similar to this:
Port Group 1 – Enabled
Port Group 2 – Disabled
Port Group 3 – Enabled
Port Group 4 – Disabled
The multicast replication performance on the WS-X6716-10G-3CXL
gives less than 50 Gigabytes of replication bandwidth
per replication engine and 2 replication engines per network
module, giving advanced multicast replication performance
for multicast apps lie video conference, audio conference,
or collaboration applications.
The modes that are supported by the WS-X6716-10G-3CXL
are the egress and ingress multicast replication modes.
Egress replication mode gives extensively heightened fanout
because the multicast replication engine on the line card
is only utilized for hardwired, attached ports.
For power improvement, the 8-port 10 Gigabit Ethernet
module that was first displayed in 2006 uses 33 percent
less power per port than the 4-port 10 Gigabit Ethernet
module. And now, the 16-port 10 Gigabit Ethernet module
being displayed here uses half the power per port of an
8-port 10 Gigabit Ethernet module.
The power requirements of the WS-X6716-10G-3C are: 16-port
Gigabit Ethernet module with the distributing forwarding
card DFC3C is 457.8 Watts or 10.9 Amps at 42 Volts. The
base module has 389 Watts or 9.25 Amps at 42 Volts, or
with the DFC3C at 69.3 Watts or 1.65 Amps at 42 Volts.
For the WS-X6716-10G-3CXL, the wattage is 487.2 or 11.6
Amps at 42 Volts. This power standard is inclusive of
the power used by the 16 transceiver optics on a loaded
16-port network module.
The 16-port 10 Gigabit Ethernet module comes with a 40
Gigabit per second connection to the fabric board so is
4:1 ratio oversubscribed. The DFC card can move IP traffic
at a speed of up to 48 million packets per second. The
weight of the 16-port 10 Gigabit Ethernet module is roughly
13 lbs. (pounds), not including X2 optic modules. For,
each X2 optic weighs .25 pounds. For example, four X2
optic modules would weigh 1 pound.
For memory, both the WS-X6716-10G-3CXL and the WS-X6716-10G-3C
include 1 Gigabyte of DRAM. The primary differences between
the Cisco WS-X6716-10G-3C and the Cisco WS-X6716-10G-3CXL
are in IPv4 and IPv6 routes, and NetFlow Entries are increased
on the DFC3CXL. A company would prefer the WS-X6716-10G-3CXL
if they are conditioned to utilizing numerous IP routes,
and double the amount of NetFlow entries that might normally
be used. The DFC3CXL provides more scalability by allowing
more routes, and entries, and ACLs to be used at any time
for use or buffering.
Cisco Systems, Inc. does not intend to make a 16-port
10 Gigabit Ethernet module without either DFC card. The
reason is that the 16-port 10 Gigabit Ethernet base board
comes with a 40 Gigabits per second connection to the
fabric. Cisco says that most of their end user customers
that would make use of this card would intend and like
to utilize it with the switching operation for maximum
utilization of such a high-density network module.
For network operators desiring to also utilize CFC daughter
cards like the centralized forwarding card (CFC) in the
same 6509 will be able to do so. Cisco has blended the
E Series chassis to be able to perform with both CFC and
DFC daughter cards in the exact same chassis. By doing
this, the chassis will function in the mode of the lowest
common denominator of daughter card. For example, if a
chassis had both a DFC3C and a DFC3CXL in it, then it
would function at the level of the DFC3C. In order to
maximize on the full potential of the WS-X6716-10G-3CXL,
the entire chassis would have to have like modules to
utilize the benefits of the DFC3CXL card.
The DFC3C supports all of the capabilities and functions
of the DFC3B. Also, it is able to support VSL (Virtual
Switch Link) and 96K MAC entries as well. If a customer
has already procured a WS-X6716-10G-3C, Cisco makes an
upgrade kit to enhance the 3C with a DFC3CXL daughter
card. Standard on both cards is the 1 GB of DRAM, so customers
have a DRAM hot swappable spare they can utilize if necessary.
Every Cisco Catalyst 6500 Series chassis supports the
16-port 10 Gigabit Ethernet module. The E-Series chassis
contains the NEBS 3 compliant configuration and supports
temperatures as high as 55 degrees Celsius. If the end
user is working with a Non-E Series Cisco Catalyst 6500
chassis, like a WS-C6506, WS-C6509, WS-C6513, or WS-C6509-NEB-A,
then 2500 watt power supplies are definitely required.
Also, the configuration is not NEBS 3 standardized, so
it only carries working temperatures up to 40 degrees
Celsius. To our surprise, the WS-X6716-10G-3C and WS-X6716-10G-3CXL
modules are not supported in the 6503 non-E 6500 Series
switch chassis.
The supervisor engine that works compatibly with the
WS-X6716-10G-3CXL is basically any Cisco supervisor engine
that utilizes Cisco’s VSS technology. This would
be any 720-10G supervisor engine or any Supervisor Engine
720 that would qualify for use. Also, this module is supported
on the Cisco VS-S720-10G-3C, the Cisco VS-S720-10G-3CXL,
the Cisco WS-SUP720, the Cisco WS-SUP720-3B, and the Cisco
WS-SUP720-3BXL. The software that comes with the unit
standard and which is supported is the Cisco 12.2(33)SXH2
IOS. Both the IOS modularity and Native IOS release are
carried.
Also, one of the benefits is being able to establish
a virtual switch link utilizing the WS-X6716-10G-3C or
the WS-X6716-10G-3CXL by using the 10 Gigabit Ethernet
ports working in performance mode. Ports in oversubscribed
mode will not work to make a virtual switch link. Another
benefit is that VACL can be captured on the 16 Port 10
Gigabit Ethernet module with the base IOS or above. Cisco
7600 hybrid router/switches do not support the WS-X6716-10G-3C
or WS-X6716-10G-3CXL.
It is important to use the newest versions of optics
as the early versions did not contain EMI advances, but
the newer versions of the SR, ER, LR, LX4, and CX4 have
the necessary EMI enhancements.
In summary, the Cisco Systems WS-X6716-10G-3CXL and Cisco
WS-X6716-10G-3C have enormous density, and with the flexibility
of dual modes of operational mode and oversubscription
mode, network administrators can choose which areas can
be utilized most. And yet again, with mobile applications
and video broadband being used more and more, the 16-port
10 Gigabit Ethernet network modules meet the challenge
where LAN campuses and data centers alike can greatly
benefit from the new and enhanced density and flexibility,
not to mention the dramatic increase in IPv4 and IPv6
routes reaching one million routes. These are great network
modules, and they are ready to sell here at GGI Networks.
