What is the backplane of Cisco WS-C3850-24P-S?

I have a switch WS-C3850-24P-S, just don’t know what is the backplane for it, and for layer 2 and layer 3. Does anyone know this? Any help would be appreciate!

The switch capacity It is by the number of ports and not layer-2/3.
176 Gbps on 48-port models
92 Gbps on 24-port models
68 Gbps on 12-port model
And the difference series switch of the same port number, the capacity is difference.
For example:
the Cisco 3750X-24 has 160 Gpbs, while the 3850-24 has 96 Gbps.
On the
3750x series, regardless of the number ports they all have the same capacity which is 160 vs 92 and 176 on the 3850s. On the other hand, the 3850s can work as a wireless controller, but the 3750xs don't have this capability.

What is the prerequisite for cisco ips exam

Hello everyone
What is the prerequisite for cisco ips exam?
I read 640-553 is required. and for 640-553 is ccna prerequisite?. i am not sure please guide me as i am new to cisco world

You can take the Cisco IPS exam, however, you will only get the Cisco IPS Specialist certificate if you pass both CCNA Security and the Cisco IPS exam.
Here is the URL for your reference:
http://www.cisco.com/web/learning/le3/le2/le41/le85/le58/learning_certification_type_home_extra_level.html
However, you can take the Cisco IPS exam first prior to taking the CCNA Security. The order of exam does not matter, and you will only get the Cisco IPS Specialist certificate once you pass both CCNA Security and Cisco IPS exam.
Hope that helps.

What is the Definative answer to JVC HDV 24p compatibility with FCP 5.1

I spoke with JVC yesterday and they claim that the 24p HDV codec is now supported with FCP. I am shooting a PBS piece in two weeks and wonder if it is safe to shoot in 24p HDV with the JVC HD100u. Is there a current state of the craft answer?

What is the difference between SmartNet and SMBS service level

Good Afternoon
I would like to ask if what is the difference between Cisco's SmartNet and Cisco's SMBS service level?
Thank you

Hi Rey,
SMARtnet covers traditional Cisco products (enterprise products ie. ISR routers), Small Business Support Center covers the small business line.
In the UC group of products, for some reason, Cisco considers the UC520, AP521, and WLC526 which are branded small business to be traditional Cisco products and are covered under SMARTnet. But, the UC540 and UC560 are covered by SBSC. One major difference in the UC arena is the support for CLI vs CCA config.
However, I noticed your post was in the Small Business - switches category. If you have a small business switch those are covered by SBSC not TAC. SBSC will support the CLI and web gui config of the small business switches, where CLI is applicable to the model.
SBSC contracts tend to be for 3 year periods and can be significantly less expensive than SMARTnet agreements.
Hope that helps.
Best,
David

The purpose of Cisco Unified CCX WebServices

Can anyone tell me, what is the purpose of Cisco Unified CCX WebServices in UCCX ? I couldn't find the description of this service neither in Google nor at Cisco site.
Thanks in advance for your answers.

What is the Cisco tool for measuring traffic of wireless endpoint users

Hi Experts
I am looking to start a Mesh WISP utilizing Cisco Aironet products (1500 series) and would like to know what is the best Cisco (or if the case has to be "non Cisco") product for measuring the amount of traffic from wireless clients connected to my Cisco Mesh.
Basically I want to be able to say User xyz has this IP xxx.xxx.xxx.xxx how much have they uploaded and how much have they downloaded this month.
This also then allows me to integrate multiple business mobile devices into their broadband plans which is something no-one yet offers in my City.
From what I have read Netflow is the measurement technology but how do I take this data and aggregate it by IP / User for billing purposes. Is there something better at it than Netflow? Your expert opinions and suggestions are much appreciated.
Regards
Ty

That sounds like Cisco Wireless Control System (WCS).

What I would like from Cisco is the meaning of all level 3 or lower email messages my Router can send to me. So, that I can take the appropriate actions.

My Small Business Router has been sending me email messages. This is a RVS-4000 version 1.
I just want to understand what my Router is emailing me or telling me...
The last message I received from my RVS-4000 was:
Oct 30 13:44:09 - IPSEC EVENT: KLIPS device ipsec0 shut down.
IPSEC EVENT sounds important. Whatever it is... And what is a KLIPS device ipsec0 shutdown????
I have Log Levels 0-3 selected...
Log Level
Setting which level log Router should recorder. Level from 0 ~ 7 means:
0: LOG_EMERG(system is unusable)
1: LOG_ALERT(action must be taken immediately)
2: LOG_CRIT(critical conditions)
3: LOG_ERR(error conditions)
4: LOG_WARNING(warning conditions)
5: LOG_NOTICE(normal, but significant, condition)
6: LOG_INFO(informational message)
7: LOG_DEBUG(debug-level message)
So, when I get any messages... I'm a little concerned. Because the RVS-4000 thinks it's an Error or better.
What I would like from Cisco is the meaning of all level 3 or lower email messages my Router can send to me. So, that I can take the appropriate actions.
I know Cisco inhered these Small Business Routers. When they bought Linksys. However, they have not discontinued them totally and they are still for sale. And Cisco has released a new version 2 of the same Router. So I believe Cisco should support them as well.
Yes, I'm a pain to Cisco. However, I think you understand I'm being scared by my Routers messages to me... And would like some relief.

Great suggestions. Problems is this is not the forum for your "wish list" as Apple does not read these USER forums.

What are the features supported in Cisco Prime Infrastructure for WLAN for autonomous AP's?

What are the features supported in Cisco Prime Infrastructure for WLAN for autonomous AP’s?

• PI provides visibility for autonomous clients within the same list view as lightweight and wired clients (client list page).
• Rogue AP detection for autonomous AP's is not supported (it's supported in CUWN).
• Alarms/events for client authentication issues (e.g. authentication failure) are displayed in PI.
• Config management for autonomous AP's is via CLI template. Config comparison and archiving functionality in PI leverages these same features that were brought in from LMS, so need to defer to others in terms of whether this is a cross-platform feature in PI or is only supported on a subset of platforms. Config comparison/archive is supported in CUWN.PI supports both infrastructure (e.g. AP Tx Power and Channel, busiest AP, AP utilization, etc.) and client (e.g. client count, client sessions, etc.) reports, and there are extensive reports for CUWN

What are the ideal settings for my TC with Shaw's Cisco DPC3825 router/modem

My old 2nd Gen Time Capsule crapped out and now I am about to set up my new 2TB TC. My provider is Shaw Communications and they have upgraded me to their Broadband 100 Mbps service. This came with a new modem/router combo made by Cisco and is model DPC3825. Before I start plugging things in I'd like to know what are the ideal settings such that I gain the most of the BB100 service. Should I be setting the Cisco modem/router to Bridge mode or the TC? Should I have Shaw disable anything? Any insight is greatly appreciated.

Unless you specifically need to have the TC perform as the main router for your network, life will be a lot easier if you configure the TC to operate in Bridge Mode.
Whether the Cisco modem/router or gateway can possibly be configured to act as a simple bridge mode modem is one thing to consider.
Whether Shaw would support you in the event of any connection difficulties with the modem/router configured this way is another.
Since Shaw is your provider, it might make sense to talk with them about best practice as far as configuring the DPC3825.
Once you have that information in hand, you will then have the answer on how best to configure the TC.....which will very likely be in Bridge Mode.

Calculate? Calculate for wirespeed/line-rate? If the latter, take all the port bandwidths, and assuming they are duplex, double for necessary fabric bandwidth. I.e. 48 gig ports would need a 96 Gbps fabric. Take all your port bandwidths, and allow 1.448 Mpps per gig (for minimum size Ethernet packets), i.e. 48 gig ports would need 69.5 Mpps. Once you have required fabric bandwidth and PPS, you can compare to vendor's specs.
