A: Yes. An onboard web GUI is available.
Q: What is the purpose of the blue beacon LED on the Cisco Catalyst 9000?
A: The blue beacon LED is common across the Cisco Catalyst 9000 Series Switches to simplify the operations. It makes chassis identification easier when several such switches are mounted on racks. A remote administrator can enable the LED to blink to help the local operator quickly locate the chassis. The local operator presses the mode button to acknowledge.
Q: What is the maximum number of VRF instances that I can configure on a Cisco Catalyst 9000?
A: The maximum number of VRFs that you can configure on a Cisco Catalyst 9000 is 256.
Q: What is Cisco’s direction for wireless?
A: Cisco believes that the best solution for a wired or wireless network is achieved when integrated into SD-Access, Cisco’s lead architecture for the next-generation enterprise network. This solution delivers consistency with wired infrastructure around policy, segmentation, orchestration and automation, and assurance. This new architecture delivers the best experience for mobility, guest, IoT, multicast services, and overall network performance with its distributed data plane and centralized control-plane architecture.
Q: What wireless support is provided with the Cisco Catalyst 9000 platforms?
A: Cisco Catalyst 9000 products are instrumental in supporting the following wireless capabilities in the SD-Access architecture:
• Connect access points and integrate them into the SD-Access fabric. The switch integrates with the fabric control plane (LISP), thereby providing reachability for the access points and clients in the fabric.
• Deliver macro (VRF) and micro (Scalable Group Tag (SGT) [SGT] group-based) segmentation to the access points to deliver end-to-end policies.
• Can terminate guest VXLAN traffic, so there is no need for a dedicated guest anchor controller.
The support for wireless capability at launch will be together with the AireOS 8.5 Controller running on an Cisco 8540 Wireless Controller, Cisco 5520 Wireless Controller, or Cisco 3504 Wireless Controller appliance with the Cisco Catalyst platforms functioning as Fabric Edge and Fabric Border nodes.
Q: What are the SD-Access wireless capabilities?
A: The new Cisco Catalyst 9000 Series switches provide a complete solution for Campus with Cisco AireOS Conrollers and Wave 2 access points.
Q: What are the advantages of integrating wireless in the SD-Access fabric architecture?
A: • Highest performance and scale: Distributed data-plane forwarding in hardware distributed in the network paired with the large control-plane scale offered by the dedicated controller appliances.
• Best guest: You don’t need a dedicated guest anchor controller in the Demilitarized Zone (DMZ): Traffic is sent directly to the fabric border to exit the fabric. Also, there is no sub-optimal traffic forwarding such as from an access point to a foreign controller and on to a guest anchor controller.
• Best mobility: IP addressing is simpler; there is one subnet for the entire wireless SSID across the network, and no hairpin of traffic when roams occur.
• Simple operation: Operation is simple because wired and wireless are treated the same and operated together; they have common policies and controller-based automation.
• Wired innovations applied to wireless: First-hop security innovations available for wired can also be applied to wireless; for example, Dynamic ARP Inspection (DAI), IP Source Guard (IPSG), and DHCP Snooping.
• Segmentation across wired and wireless:
-The virtual network now passes all the way to wired as well as wireless devices.
-This segmentation is important for separation of certain devices from others, such as IoT and building automation devices connected over wireless.
-It is also important for security reasons to reduce attack the surface; if someone gets into a segment, the person can move only within that segment.
-Because segmentation is handled by the fabric, the number of SSIDs can be limited.
• Best multicast:
-The solution offers the best performance of distributed replication in hardware across the network.
These switches truly deliver the best of wired and wireless together.

Q. What cellular modems are integrated in the C880G Series ISRs?
A. There are two different types of carriers. One type supports third-generation Partner Project (3GPP) HSPA+, HSPA, Universal Mobile Telecommunications Service (UMTS), Enhanced Data rates for Global Evolution (EDGE), and General Packet Radio Service (GPRS), and the other supports 3GPP2 EVDO RevA/Rev0 and 1xRTT. Two cellular modems support 3GPP2: MC8705 and MC8795V, and one cellular modem supports 3GPP2: MC5728V.
Q. What is the cellular modem form factor in C880G Series ISRs?
A. The external 3G ExpressCard socket on Cisco 880G Series routers has been replaced by an internal PCIe mini-card slot on C880G Series routers. The external ExpressCard modems, therefore, have been replaced by the internal PCIe mini-card cellular modems.
Q. What is the function of the mini-USB port in C880G Series ISRs?
A. C880G Series routers have a mini-USB type B port that enables the modem to be connected to a PC and run PC-based modem provisioning and the carrier customization tool.
Q. Do the C880G Series ISRs support the Diagnostic Monitoring (DM) port?
A. C880G Series routers have removed the Diagnostic Monitoring port from the chassis front faceplate. The remote Diagnostic Monitoring function is required to collect the modem Diagnostic Monitoring log.
Q. Do the C880G Series ISRs support the National Marine Electronics Association (NMEA)?
A. C880G Series routers support NMEA. A virtual serial port is implemented to export NMEA format GPS data to external NEMA 2.0-compliant user applications.
Q. How do I configure NMEA on C880G Series ISRs?
A. To enable NMEA GPS data streaming, C880G Series routers have introduced two new command-line interfaces (CLIs): cdma|gsm gps modem standalone and cdma|gsm gps nmea. A virtual serial port has been implemented in the Cisco IOS Software to export NMEA-formatted GPS data. If end users connect the router to a Microsoft Windows-based PC through an Ethernet connection COM port emulation software is required on the PC side to emulate the COM port over the Ethernet link.
Q. What NMEA sentences do the C880G Series ISRs support?
A. C880G cellular modems support the following NMEA sentences: GGA, GSA, GSV, RMC, and VTG.
Q. How many SIM card slots do the C880G Series ISRs support?
A. C880G Series routers support two SIM card slots, which allow cellular modem failover to the secondary SIM card to continue service when the modem loses services to the primary SIM card.
Please refer to the Cisco 819 Integrated Service Router Q&A and “ Configuring Cisco EHWIC and 880G for 3.7G (HSPA+)/3.5G (HSPA)” for more information about how to use and configure dual-SIM.
Q. Is dual-SIM supported on CDMA 3GPP2 based C880G Series ISRs?
A. C880G CDMA 3GPP2 Series routers do not support the SIM card; therefore, the dual-SIM feature is not supported on these routers.
Q. How do I send, display, delete, and archive SMS on C880G Series ISRs?
A. C880G Series routers have an SMS function that enables the routers to send and receive SMS messages. This feature also enables the routers to save and store the SMS messages in an FTP server. SMS is enabled by default. You can send, display, delete, and archive SMS through the router CLI.
Q. Is encapsulation ppp supported by C880G Plus 7 Series ISRs?
A. No. C880G Plus 7 Series routers support encapsulation slip by default.
Q. What is Direct IP on C880G Plus 7 Series ISRs?
A. C880G Series routers are integrated with a Sierra Wireless MC8705 cellular modem that is running under Direct IP mode to maintain HSPA+ data throughput. Direct IP is a Sierra Wireless proprietary framing protocol used to transfer data between the host platform and the modem. Direct IP framed data have a dedicated USB connection, meaning the host can still send AT commands after the direct IP data session is established. Cisco IOS Software sets encapsulation to SLIP based on the data link protocol between the host and the modem.
Q. What WLAN antenna options are available for C880W Series ISRs?
A. All C880W Series routers embed three dual-band 2.4- or 5-GHz Planar inverted-F antenna (PIFA)-type omnidirectional antennae. External swivel-mount dipole antennae are no longer used. Antennae are attached to the cover of the chassis and covered by the front bezel, and U.FL-type RF connectors attach to the radio.
Q. Do the Cisco 880 WLAN Series routers have removable WLAN antennae?
A. Only Cisco 881 WLAN Series routers have removable swivel-mount dipole antennae. Other products in these routers have captive default dipole antennae. Removal of them and support for other types of external WLAN antenna is not supported by Cisco.
For all kinds of customers, what can they expect from Cisco in 2017? In the following article, Zeus Kerravala (the founder and principal analyst with ZK Research, and provides a mix of tactical advice to help his clients in the current business climate.) listed the main points that users and clients expect from Cisco in 2017.
- Cisco will take a chunk of the security market. The security market is easily the most fragmented of all of the IT submarkets. It’s currently a $75 billion market, with no single vendor having anywhere close to double-digit share. Cisco, in particular, has fumbled around in security for years with different initiatives and architectures that have been ineffective.
Times are different today. As I pointed out in an earlier post, Cisco has never been positioned better in the security industry, and the company is finally using its greatest asset—its dominance in the network—to create tangible differentiation. Look for 2017 to be the year it breaks away from the competition and takes a chunk of the security share.
- Cisco breaks away in collaboration. Collaboration at Cisco has had its ups and downs over the past few years, but the company now pointed in the right direction. Spark was launched as a Slack-like team collaboration tool, but in actuality, it’s much more than that. It’s a fully integrated cloud, hardware and software experience that can deliver seamless, easy-to-use experiences on a mobile phone, desktop or meeting room. Expect Cisco to continue to innovate around Spark and create its next wave of growth in collaboration.
- The data center gets a shot in the arm with an acquisition. The Unified Computing System (UCS) carried the data center business unit at Cisco for years. Recently, though, the growth of the product has slowed. In fact, this past quarter saw the data center revenue fall 3 percent.
UCS is a great product, but the compute industry is shifting to hyperconverged infrastructure (HCI). Cisco’s current offering, HyperFlex, is an OEM from SpringPath, and channel feedback has been that they would prefer Cisco to own the product rather than OEM it. The OEM allows Cisco to dip its toe in the water, and in 2017 Cisco will jump in with both feet by acquiring SpringPath, which will stimulate data center growth.
- Expect Cisco to focus on analytics. When one thinks of analytics, the name Cisco is rarely top of mind. However, analytics is becoming a core component of Cisco’s strategy. Not only is it at the core of the recently announced Tetration product, but it is also fundamental to the company’s differentiation in security, Internet of Things, network operations and collaboration. Expect to see Cisco do more analytics on more network data to differentiate its offering from the many smaller competitors that can’t match its footprint.
- Cisco will push its engineer base to learn new skills. Markets transition. That’s a fact. And when then do, the engineers who work with the technology need to change their skills. Most vendors don’t see the transition, won’t admit its happening or don’t want to upset their engineer base by forcing them to change. And that always ends up being a disaster.
Think of engineers who worked with mainframes, Token Ring, TDM voice, SNA and other trends. Most are gone, as are the vendors that sold the stuff.
One of Cisco’s competitive advantages is its huge base of engineers, many of whom are steeped in the way networking was done. Based on my discussions with Cisco executives, including Jeanne Dunn, who runs Cisco’s learning group, I believe Cisco wants to disrupt its engineer base and have them learn new skills—such as automation, data sciences, programming and business skills. Some won’t like the changes to the certification requirements, but the fact is Cisco engineers need to start developing skills for the digital era.
- Executive churn will slow down. Since Robbins took the helm, there has been a steady churn at the executive level, including Kelly Ahuja, Rob Soderberry and the famed “MPLS” group—just to name a few.
I believe Robbins’ team is set now. And while there might be the odd departure here and there, this is the team he’s going to run with.
One question I’ve been asked is if the company would replace the recently departed CTO Zorawar Biri Singh. I believe engineering is in the best hands they can be under the co-leadership of Rowan Trollope (IoT and applications) and David Goeckeler (networking and security), and the structure will stay as is. Get used to the faces at the top; they should be sticking around for a while.
One thing that will remain the same at Cisco is the company’s commitment to changing the world. Cisco’s former CEO, John Chambers, had a great desire to have Cisco make the world a better place. As I pointed out earlier this year, Robbins has picked up the Corporate Social Responsibility (CSR) ball and is running with it faster than ever.
The world is becoming increasingly digitized, and many of the digital enablers—such as IoT, cloud and mobility—are network centric. The coming year presents Cisco a great opportunity to flex its enormous networking muscles and move into the next wave of growth.
