Do you know something about the Cisco Catalyst 6900 Series 40 Gigabit Ethernet Interface Module for Cisco Catalyst 6500 Series Switches? Such as Cisco WS-X6904-40G-2T.

The module is designed to meet the increasing demand for aggregation of 10 Gigabit Ethernet on campus and data center, as well as for high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet transport in the core.

Each port can accept a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics module or be converted to four ports of 10 Gigabit Ethernet with a FourX adapter, enabling customers to deploy 10 Gigabit Ethernet to meet current needs and be ready to transition to 40 Gigabit Ethernet without any disruption. The module can also be used in mixed mode, where one side of the card uses two CFP modules for 2 times 40 Gigabit Ethernet ports and the other side uses two FourX adapters for 8 times 10 Gigabit Ethernet ports.

The Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module is compatible only with Cisco Catalyst 6500 Supervisor Engine 2T.

Cisco Catalyst 6900 Series 4-port 40 Gigabit Ethernet Fiber Module can operate in a number of modes. Performance mode enables 80 Gigabit Ethernet performance by using two ports without oversubscription. In Oversubscribed mode, the module uses four ports with 2:1 oversubscription.

The 4-Port 40 Gigabit Ethernet Fiber Module provides up to 44 x 40 Gigabit Ethernet Fiber ports in a single Cisco Catalyst 6513-E chassis and 88 x 40 Gigabit Ethernet ports in a Cisco Catalyst 6500 Virtual Switching System (VSS) 4T. The module has two 40-Gbps connections (for a total of 80 Gbps) to the 2-Tbps switch fabric of the Cisco Catalyst Supervisor Engine 2T, providing 2:1 oversubscription when all four ports of 40 Gigabit Ethernet or 16 ports of 10 Gigabit Ethernet ports are active.

Cisco Catalyst 6904 modules support two types of CFP optics: CFP-40G-LR4 and CFP-40G-SR4, providing operational distances of up to 10-km over single-mode fiber and 100m over OM3 multimode fiber, respectively. FourX adapters support a variety of Small Form-Factor Pluggable Plus (SFP+) optics

802.11ac vs. 802.11n
802.11ac vs. 802.11n

802.11ac is important? Do you want to upgrade to 802.11ac? Why? 802.11ac addresses the speed and capacity challenges facing the next-generation unified access network

● Wi-Fi is the primary access method for all new devices.

● Cisco VNI trend data shows that by 2016 over half of all IP traffic will originate on fixed Wi-Fi.

● Chip manufacturers have accelerated their delivery timetables for 802.11ac to meet device manufacturers’ demands.

● Wi-Fi is assumed. Device manufacturers have never included Ethernet ports on smartphones or tablets, and they are no longer including Ethernet ports on laptops.

Benefits of 802.11ac

802.11ac offers longer battery life, more bandwidth, greater client density, and fast client adoption.

Longer battery life: Better airtime utilization means devices are on and off the network more efficiently, conserving precious battery life.

More bandwidth: Three to four times higher throughput than 802.11n means users have better experience for data, voice, video, virtual desktops, etc.

Greater client density: More users and more devices per user can be accommodated.

Fast client adoption: Client devices such as smartphones and tablets are adopting 802.11ac faster than 802.11n.

802.11ac radios also support 802.11a/n clients.

● Most enterprise-grade access points provide at least two radios: 2.4 GHz for 802.11b/g/n and 5 GHz for 802.11a/n.

● 802.11ac is offered only in the 5-GHz band.

802.11g/a/n vs. 802.11ac

The differences are found in frequency, speed, modulation, battery savings, and channel width.

Frequency Band: 802.11n operates in both the 2.4-GHz and 5-GHz band. Both 802.11a and 802.11ac operate in 5 GHz band only.

Speed: Some of the latest generation of 802.11n access points have a maximum datarate of 450 Mbps. Wave 1 of 802.11ac provides a maximum datarate of 1.3 Gbps, and Wave 2 will offer a maximum datarate of 6.9 Gbps.

Modulation: 802.11ac provides 256 quadrature amplitude modulation (QAM) vs. 64-QAM for 802.11n. Basically, when you have better modulation, you can transport more data. 802.11ac can operate up to three times faster than 802.11n.

Battery savings: Since 802.11ac devices are more efficient over the air, they transmit for shorter intervals, conserving battery life. 802.11ac has been shown to improve battery life by up to 2x over 802.11n.

Channel width: 802.11n allows a 20 MHz and 40-MHz channel. 802.11ac allows up to 80-MHz channels in Wave 1 and 160-MHz Channel in Wave 2.

Has the 802.11ac standard been ratified? Yes; the ratification and publication of 802.11ac by IEEE was completed December 9, 2013, and ANSI approved it on December 11, 2013. (The 802.11 timeline updates can always be found under the “RevCom & Standards Board Final or Continuous Process Approval” at http://www.ieee802.org/11/Reports/802.11_Timelines.htm.)

What is the difference between Wave 1 and Wave 2 of 802.11ac?

The biggest difference is that Wave 1 802.11ac is available now and the expectation is that 802.11ac Wave 2 will come to market in CY15.

● 802.11ac Wave 2 will require new hardware, so it will not simply be a software upgrade to current 802.11ac platforms.

The main features of 802.11ac Wave 1 include: The maximum datarate is 1.3 Gbps; Channel bonding support for 80 MHz (mandatory); Three spatial streams, single-user multiple-input and multiple-output (MIMO); Two spatial streams are mandatory for non-battery-powered access points; Only one spatial stream is mandatory for battery-powered access points and clients; Faster modulation: 256-QAM

The main features expected in 802.11ac Wave 2 include: Multi-user MIMO; Up to 8 spatial streams; 160-MHz-wide channels; Maximum datarate is 6.9Gbps

Why deploy 802.11ac Wave 1?

◦ You can expand your network and adopt 802.11ac Wave 1 today, instead of buying 802.11n or waiting for Wave 2, which won’t be available until 2015.

◦ 802.11ac Wave 1 represents fundamental improvements and enhancements to 802.11n in terms of client performance due to three to four times higher throughput than 802.11n.

◦ Device users can expect to have better experience for data, voice, video, virtual desktop, etc.

◦ Wider channel bandwidth in 802.11ac means more real estate to support higher client density in conference rooms, auditoriums, and stadiums.

◦ Client devices are adopting 802.11ac faster than 802.11n.

◦ Smartphones, tablets, and laptops are on and off the network faster with 802.11ac, thereby conserving battery life.

What benefits can I expect with 802.11ac Wave 2?

◦ MU-MIMO switch-like behavior will allow for an even higher number of concurrent Wi-Fi devices.

◦ Higher throughput is expected with the additional spatial streams and 160-MHz-wide channels.

How does Cisco support 802.11ac? Cisco also offers the Aironet 2700 and 3700 Series Access Points, both of which have integrated 802.11ac Wave 1 radios. Cisco also offers an 802.11ac module that can be added to the Cisco Aironet 3600 Series Access Points.

● The Cisco Aironet 3700 Series also support a modular architecture that allows expansion to the Wireless Security Module, the 3G Small Cell Module, and support for future technology such as 802.11ac Wave 2.

Both the Cisco Aironet 3700 and 2700 Series supports Cisco’s High Density Experience (HDX) technology.

● Cisco’s HDX High-Density Experience is a purpose-built Innovative Chipset designed specifically for the high performance environments of 802.11ac.

● The features of HDX includes:

◦ Turbo Performance which Scales to Support More Devices

◦ Running High Bandwidth Apps

◦ Optimized Roaming which Intelligently Decides the Proper

◦ Access Point as People Move

◦ Cisco’s CleanAIr with 80MHZ channel support which mitigates interference and improves channel capacity

◦ Cisco’s ClientLink 3.0 which improves legacy and 802.11ac Client performance

◦ Cross AP Noise Reduction (future) which enables dense Access Point Coexistence/implementation

Each of the WLCs that receives the LWAPP discovery message replies with a unicast LWAPP discovery response message to the LAP.

How to assign static ip to lightweight Access Point 1131AG before registering to controller? Some user raised the question like that: He has Wireless LAN controller (WLC) is installed in corporate office with H-reap enabled so that remote office access point can be registered with corporate office controller. This AP was registered with WLC on different subnet and he has shifted this AP to other remote office and want to assign static IP address.

More Notes: APs are “lightweight,” which means that they cannot act independently of a wireless LAN controller (WLC). The WLC manages the AP configurations and firmware. The APs are “zero touch” deployed, and individual configuration of APs is not necessary. The APs are also lightweight in the sense that they handle only real-time MAC functionality. The APs leave all the non-real-time MAC functionality to be processed by the WLC. This architecture is referred to as the “split MAC” architecture. We cannot configure the LAP to operate independent of a wireless LAN controller (WLC). LAPs cannot function independent of WLCs. LAPs function in conjunction with a WLC only. The reason is that the WLC provides all the configuration parameters and firmware that the LAP needs in the registration process.

While assigning static IP address to remote site AP through console before registering to the controller, after login into the AP, we got the console with below name:

......MAC Address....>

But when we try any command to assign IP address, it shows the error "Command Disabled"

Condition

We can connect this AP to corporate office LAN and get registered with WLC and then through WLC GUI and can assign static IP address but we need solution to assign static IP before getting registered to WLC.

We Also tried the following command, but got error "Command disabled "

AP#lwapp ap ip address <IP address> <subnet mask>
AP#lwapp ap ip default-gateway <IP-address>
AP#lwapp ap controller ip address <IP-address>
AP#lwapp ap hostname <name>

By Default in LWAPP APs the config commands are disabled. We need to issue the command:

"debug lwapp console cli"
or
"debug capwap console cli"

(depending on the version of the sw of the AP)

After this you can use the AP config as you would do in IOS APs.

Workaround

There is one Bug CSCsy17745 filed for this issue. The workaround will be helpful to fix the issue: http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsy17745

The command DEBUG LWAPP CONSOLE CLI is a HIDDEN command. Please enter the complete command and then you need to perform the work around mentioned in this Bug.

"lwapp ap" CLI always returns "ERROR!!! Command is disabled.".

Symptom:

When attempting to configure a lightweight AP using the "Ease of Deploy" CLI, i.e. the "lwapp ap" exec mode command, from the console, the following error is returned:

ERROR!!! Command is disabled.

Conditions:

The access point is running the lightweight IOS featureset (k9w8) or recovery image (rcvk9w8).

Workaround 1:

1. configure the AP to boot the recovery image:
ap#debug lwapp console cli (use "debug capwap console cli" if running 5.2 or above)
ap#dir flash:/ (look for a folder with "rcvk9w8" in its name)
ap#configure terminal
ap(config)#boot system flash:/c1250-rcvk9w8-mx/c1250-rcvk9w8-mx

2. disconnect the AP from the LAN (e.g. shutdown the switchport)

3. reload the AP

4. from the AP console, clear the LWAPP (CAPWAP) configuration:

ap#clear lwapp private-config

5. You can now enter the "lwapp ap" "Ease of Deploy" CLI commands.

Workaround 2:

1. Disconnect the AP from the LAN (e.g. shutdown the switchport)

2. ap#debug lwapp console cli (use "debug capwap console cli" if running 5.2 or above)

3. ap#write erase

4. ap#reload

5. After reloading, you can now use the "lwapp ap" (or "capwap ap")

"Ease of Deploy" CLI commands.

Workaround 3:

ap#test lwapp controller ip a.b.c.d [w.x.y.z] (or "test capwap controller")

More information:

Even with the resolution of this bug, the "capwap ap hostname" CLI is still disabled. See CSCtl96208.
