1921 Router Q: How many IPsec tunnels will it support?

Sorry if this isn't the spot for hardware questions... I need to know how many IPsec VPN tunnels one Cisco1921 can support reliably. Haven't had any luck sifting through documentation on the web.
Thanks in advance for any help!

The SEC-K9 permanent licenses apply to the Cisco 1900, 2900, and 3900 ISR G2 platforms; these licenses limit
all encrypted tunnel counts to 225 tunnels maximum for IP Security (IPsec), Secure Sockets Layer VPN (SSL
VPN), a secure time-division multiplexing (TDM) gateway, and secure Cisco Unified Border Element (CUBE) and
1000 tunnels for Transport Layer Security (TLS) sessions.
The SEC-K9 license limits encrypted throughput to less than or equal to 85-Mbps unidirectional traffic in or out of
the ISR G2 router, with a bidirectional total of 170 Mbps. This requirement applies for the Cisco 1900, 2900, and
3900 ISR G2 platforms. The SEC-K9 permanent licenses apply to the Cisco 1900, 2900, and 3900 ISR G2 platforms; these licenses limit
Thanks

How many IPSec Tunnels an ASA 5500 series supports

Hi All,
I tried looking in ASA documentations but unable to find out that how many IPSec Tunnels can be terminated to an ASA cluster. I have 5545 running only two IPSec Tunnels so far but need to terminate 18 sites all up and would like to confirm how many tunnels we could terminate? Is there a limitaion to it?
Thanks heaps
Shan

Yes, there is a limit. But its far away from your requirement. On the 5545-X you can terminate 2500 VPN-Peers:

How many spine nodes will be supported on ACI Fabric?

Hi Experts,
I want to clarify how many spine nodes will be supported on ACI Fabric now and future(maximum number of spines)? Because there are some different speculations about that. Someone says it'll be 12, others say it'll be 16 spines. Which one is correct or others?
Thanks in advance.
Paul

Hi, Paul,
As today and the roadmap as per my information, We are still looking at 6 spines in each fabric.
Number of leafs support has more importance which is 200 within one fabric in the upcoming release Q2'15. One fabric will also support approx 100 FEXs as well.

How many ip addresses will an airport extreme handle?

I have about 60 devices in my home that need an IP address and can only imagine with the Internet of Things, wearables, security etc. that it will go higher in the future.
How many IP addresses will an Airport Extreme or Time Capsule handle reliably?
Thanks -

About 250 total wireless and Ethernet addresses, with a limit of 50 for wireless devices........assuming that it is the AirPort Extreme or Time Capsule that is acting as the router handing out the IP addresses.

How many EoIP tunnels at the same time? (One Anchor -- HA Pair )

Hi Experts,
With AP SSO, there should be two CAPWAP tunnels between an AP and the HA controller pair at the same time. Is it correct?
Then how many EoIP tunnels between the internet anchor controller and the foreign controller HA pair at the same time?
Thanks
Cedar

Hi Cedar,
in AP SSO, only single CAPWAP tunnel maintan at a time & see the below reference for details.
http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml
There is only one CAPWAP tunnel maintained at a time between the APs and the WLC that is in an Active state. The overall goal for the addition of AP SSO support to the Cisco Unified Wireless LAN was to reduce major downtime in wireless networks due to failure conditions that may occur due to box failover or network failover.This allows the access point (AP) to establish a CAPWAP tunnel with the Active WLC and share a mirror copy of the AP database with the Standby WLC. The APs do not go into the Discovery state when the Active WLC fails and the Standby WLC takes over the network as the Active WLC.
in the same sense, EoIP tunnel limitation will be 71 for a anchor controller. See below

I'm trying to back up 10.6.8 (snow leopard) and all my files before upgrade to Mavericks. I have an old but sturdy external hard drive...how many GB available will I probably need to back up the whole thing? thanks!

You will need a separate partition unless you plan to use the entire drive. You will need an amount of space somewhat larger than the total space now used on your startup drive. If you select the startup drive's Desktop icon, then press COMMAND-I to open the Get Info window. Used space will be shown in the topmost panel. Add a GB or two to that number to determine how much space you'll need for the backup.
Do not backup on a drive that has any files you want to keep. You can make a bootable backup as follows:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

How many touch points will there be in JavaFX 2.2

I know 2.2 will support multi-touch. Exactly how many touch points will be possible?

Hello, maximum number of touch points is limited only by capabilities of the used hardware and underlying operating system, there is no such limitation in FX itself.

How many users can 1 Xserve support?

I have one Xserve (10.5.2, 2x3GHz, 5GB RAM, 1.34TB RAID 5) that I want to support the following services for my SMB:
DNS, DHCP
AFP, NFS, SMB
Open Directory
Print
Software Update
I also want to have mobile sync'd network home folders, but only for ~/Documents and iCals and Address Books (I don't want everyone's MP3s or family photos).
I occasionally will use NetBoot/NetInstall, but only 1-2 users at once.
I am getting ready to migrate my company to OpenDirectory and 10.5.2 for all users and was hoping someone here might be able to tell me how many users I can reasonably support with one Xserve.
Also, is it a bad idea to have everyone using "mobile" accounts? It seems like it would be less strain on the server to have the occasional sync from users than everyone reading & writing all the time. Also, if anything happened, there would be a local copy and a remote copy of any files.
Thanks.

Rosemarie,
BeehiveOnline currently supports 95,000 users and we have groups on the system as large as 10,000, that is probably about as big as we want to go - remember collaborating with 10,000 users is not an effective way of working - maybe a more open way of delivering content may be more appropriate. Given that the only issues we have with very large groups is the time it takes to run and the email traffic it generates as the large group are processed.
So it is possible to host 10,000 in a group but we need to be warned in advance and work with you to minimise the impact as the group is set up.

How many 7920 phones can be supported on one Cisco 1131AG access point?

hi all,
who knows that how many 7920 phones can be supported on one 1131ag AP? Thanks a lot...

Hi Alomar,
Hopefully this info will help;
Number of 802.11b Phones per AP
Before any discussion about network planning can take place, it helps to understand the basics of the overall network capacity.
The following network capacity guidelines apply to sizing the Wireless IP Telephony network:
No more than 7 concurrent G.711 calls per AP.
No more than 8 concurrent G.729 calls per AP.
Note These design recommendations assume that Voice Activity Detection (VAD) has been disabled on the Cisco 7920 Wireless IP Phones. Use of VAD on the Cisco 7920 phones can conserve bandwidth, but Cisco recommends that you disable VAD on all Cisco CallManager servers to provide better overall voice quality.
In addition to determining how much bandwidth is needed for an 802.11b VoIP call, you must also consider overall radio contention for a particular RF channel. The general rule is that you should not deploy any more than 20 to 25 802.11b endpoints per AP. The more endpoints you add to an AP, the more you reduce the amount of overall bandwidth and potentially increase transmission delays.
The maximum number of phones per AP depends on the calling patterns of individual users (based on Erlang ratios). Cisco recommends no more than 7 concurrent calls using G.711 or 8 concurrent calls using G.729. Beyond that number of calls, when excessive background data is present, the voice quality of all calls becomes unacceptable.
From this doc;

Hope this helps!

How many airport express can be supported by software remote at one time.

how many airport express can be supported by software remote at one time?
I mean remote software can control at one time

Well Apple makes an iOS application called 'Remote' it's used to control iTunes on a Mac, Or to control an Apple TV Multimedia features.
Apple also makes "AirPort Utility" for iOS. Airport Utility can be used to configure Aiport Extrem, Airport Express And Time Capsul using an iPad, iPhone or iPod Touch. You can use it to connect to one device at a time. While connected to the device you can configure it to work as part of a larger Airport network. If you want to configure muliple device, you would connect to one device, configure it, And then connect to the next device, and configure it, and so on and so fourth.
I haven't found a limit.
How big of a network are you trying to make?

How many luns does mac OSX support from a single target (array) is it 255??

How many luns does mac OSX support from a single target (array) is it 255?
For example, if using the Dual-channel 4Gb Fibre Channel PCI Express card? Is it 255, 512 or higher? I know it uses the ATTO driver, but I can't find any documentaiton about the upper limits of how many luns this HBA can address from a single target array on a SAN. Thanks.

Hi,
The card should be an ATTO 42ES whcih supports 255 LUNS per channel
Here's the info from the attached link
Consider the following Celerity FC host adapter guidelines:
• ATTO 4-Gb and 8-Gb FC cards (PCI-X and PCIe only) are supported. • Latest HP-specific ATTO Celerity FC host adapter driver • Latest HP-specific ATTO Configuration Tool • A maximum of 256 targets per host adapter channel are supported. • A maximum of 255 logical unit numbers (LUNs) per host adapter channel are supported. • PowerPC- and Intel-based servers are supported.
