Devices/subnet (IP-address question)

Hi,
I am designing a wireless network. It has to be able to handle 700 laptops and 700 smartphones.
Will there be a problem to have two /22 subnets? Should it be divided in to smaler nets? One theoretical idea is to divide it by floor. But I am not sure how Cisco ISE will know what AP is on what floor. Or what hapens when a user walks from one floor(VLAN) to another.
Regards,
Philip

two /22 would be fine.
As for your Theoretical...you could use AP groups, link the WLAN to the specific floor interface/vlan. ISE doesn't need to know which AP it's coming from, as the WLC will take care of putting the client in the correct VLAN.
Unless of course you were wanting to do forced VLAN assignment
HTH,

IPv6 address questions

I'm having trouble understanding IPv6 addresses. In IPv4 the CIDR slash notation means what subnet the address is in. But a /48 in IPv6 does not mean subnet. I have no idea what it means. For instance I've seen the address 2001:0:1:5::1/64, and I have no idea what the /64 means. Can someone explain it?
Link local address: it's not enough to put an FE80 to identify this kind of address, but for some reason, they decided to put FFFE in the middle of the ipv6 address. What were they thinking? Why do they need to identify this kind of address TWICE within the address, AND why couldn't they put the FFFE at the end or the beginning, but instead they put it right in the middle? WTF?
3 types of addresses? What why? with that many bits in an address there's no reason to have 3 of them. Theres enough for everyone.
Illogical allocation of bits. A global ip address reserves the last 64 bits for the host ip. This is equivalent to 18 quintillion hosts on ONE SUBNET! YEAH RIGHT! There's no way that's even remotely logical, feasible, or practical. The more I look at IPv6 notation, the more I think my 5th grader could have come up with a better design.
Also, why didn't they adopt the OSI model of addressing, like in ISIS. That has more than enough addresses for everyone.
Obviously i'm missing the point completely on IPv6. It sounds like the most unthoughtful pile of rubbish ever conceived. So can someone please direct me to a place or explain what the thought process was when creating this new addressing scheme?
bonus points: what happened to ipv5, and what was ipv1,ipv2,ipv3? I think the inventor should have called it IPv2000, because he really went overboard.

Hi Richee,
ISPs generally give ipv6 addresses to companies with /48 prefix length.
The company receiving this can create its own subnets within the /48 and /64 range.
The last 64 for bits of the address are generally used to insert the mac-address of the local interface when using stateless auto-configuration, but you can use it for subnetting as well, if you configure your addresses manually.
For the other questions I think this link could give you more info:
http://www.cisco.com/en/US/tech/tk872/tsd_technology_support_protocol_home.html
And one more little addition:
Nothing is perfect in this universe. Everything can be considered good or bad, it is just a question of viewpoint.
Try to look at ipv6 from both viewpoints. You will have surprises.

Subnetting ip range question

Hi,
I'm from belgium, starting to get my way around Cisco and IT networking.
For the moment i'm at chapter 6 discussing subnets.
You got the network part of the bits and the host part.
If you want to create 4 subnets you take the fist 2 bits of the host part.
Than you have 62 addresses free for hosts and 4 subnets.
My question is here: what if for example, your HQ has 80 hosts that need an address.
You have the 62 addresses for one sunet, do you need to use the 2 subnets or can you combine one subnet?

Tom
I am glad that my answer was helpful. Subnetting is a topic with lots of aspects and can be confusing, especially in the beginning. As you get more experience and a better understanding it does get easier.
Your understanding is correct in terms of traditional subnetting. As subnetting was developed one of the principles was that within a particular network all subnets would be the same size, and as you state the size is driven by the requirements of the largest subnet. This did lead to some inefficiencies, as you note.
To address these inefficiencies a new approach to subnetting was developed. This is frequently referred to as VLSM, which is Variable Length Subnet Masking. Traditional subnetting with all subnets the same size was simple but not so efficient. VLSM changed the basic principle that all subnets need to be the same size and gave us flexibility and increased efficiency in subnetting by allowing subnets within a network to be different sizes. So in your case we can say that one site with 80 requires a /25 subnet (255.255.255.128) but the site which requires only 15 could then have a subnet of /27 (255.255.255.224) and that the remaining address space could then be used somewhere else.
You still can not say the subnet is from 1 to 100 and reserve 101 through 127. If the mask is /25 then all 127 addresses are in the same subnet. But now you can say that the smaller site can use a mask that more closely reflects its needs. Earlier routing protocols enforced the requirements of Fixed Length Subnet Masking while more recent routing protocols like OSPF and EIGRP support VLSM.
Good luck in learning more about subnetting.

First off, i think it's sad that i have to use my non apple device to post this question... Why has my iPad become absolutely useless after updating to iOS 8.1? I am unable to use my mini because it crashes, slow performance, major battery drain.

Restore iPad to Factory Default; do not restore from backup. It may be the cause of the problem.

Can't mount external HDD? "usb 1-1: Device not accepting address"

I just bought a Medion HDDRIVE2GO (Full Speed) from Aldi, and at first when I plugged it in, everything went fine (well, I thought so). Appearently it had some errors with HAL not being able to read the HDD (error name="(unset)").
I gave it a reboot, and now it does not work at all! In dmesg, I have this output (the bottom is the most important I guess)

I found this post on linux forums which say It's a HAL related problem.
"rmmod ehci_hcd" made it work for some of these guys Which one of them explains It's a data speed issue. Cables.., 2.0 1.0, that sort of things. Read it, I bet you'll get more out of it, It's old though.
Try removing the module, plugging the drive, check dmesg, and mount manually.

Connect to external device using ip address in lan

Hi,
I have a external device in lan ,
,want to connect this external device using ip address.

That has nothing to do with anything. Whether the resource is on the local network or accesible through the internet only is not relevent here at all. This forum is for Java network programming. If a resouce is not available because you are not connected physically to a network that is a network problem. That is not a Java progamming problem.
Okay?
There's alot of rubbish posted in this forum about "public networks" and what not and not one lick of it is related to Java programming. Yes if you connect through more routers to something there is a better chance that somewhere along the way that you will hit a firewall or other similar issue. But these are all network issues. Not networking programming issues. And not resolvable directly in Java any way you want to think about it.

SCOM Network Discovery - Duplicate nodes with different Device Keys (MAC address)

Hi There,
We have deplyed SCOM 2012 SP1 for server and network monitoring. In the "Network Devices" view, there are few duplicate node entries for the same device. When i look at the details of each entry, the device keys (MAC address) are
different. for example, if there are 3 entires for the same device, only one will have the correct MAC address and remaining 2 are incorrect.
Have anyone came across such issue? Any solution to avoid the duplicates?
Thanks.
Venu.
Best regards, Venu.

Last Thursday (9/25/14), Microsoft provided me with an updated version of a file that is used as part of the discovery process. At first, it appeared to only resolve the issue for some devices which was disappointing. On Saturday, I decided
to remove all managed devices and rediscover everything from scratch. We have 237 devices to monitor. Since Saturday, I had one ICMP only device duplicate itself, but after I removed the duplicate, I have not had any other duplicates created and
there have been many rediscoveries ru nsince then. So far so good. I've asked Microsoft to keep the case open until next Monday. This weekend, I have a full discovery scheduled to run on a schedule. I'll feel good after that if there
are still no duplicates.
The file replaced is "ic-iftable.asl" which is located on each management server in the path ""\[ SCOM install directory]\Server\NetworkMonitoring\rules\discovery". I'm not sure if I'm allowed to share the updated version of
the file. I have not received an explanation from the support technician yet as to the root cause. They took at least 5 sets of trace logs during the discovery and subsequent rediscovery process before giving me this updated file. I'll let
you know.

NI-FBUS Communications Manager won't start when PCMCIA card is configured as Basic Device and Visitor address

I can't get the NI-FBUS Communications Manager to start up unless the PCMCIA Series 2 Card is configures as Link Master. I want to Connect to a FFB Segement which already has a LAS

Hello,
The same case.
It means that fisically I have to connect the the PCMCIA to the actual segment (with its LAS) and then start up the NI-FBUS Comm. Manager?
Like a Basic Device and Visitor Address will let me change parameters at the devices?
Thanks in advance,

Router MI424WR - Device Names to MAC Addresses Question

I have Verizon FiOS with an ActionTec MI424WR Router. I have many devices connected to it on our home network: ipods, ipads, nook, kindles, laptop, roku, and a desktop.
For each device, I found its MAC address. Then I logged into the router and went to "My Network." There, I renamed each device (for example, from "android-alsdfjl3kljasdf" to "JonKindle" and "new-host-4" to "MaryIpad"). That way, I'll be able to go to the parental controls rules screen and assign each device to rules as I like.
Problem:
The names keep changing back to "android-alsdfjl3kljasdf" and "new-host-4". Not only that, but somehow, the MAC addresses keep changing. Is there a way to keep that from happening?
I thought MAC addresses were assigned to a piece of hardward and didn't change. Can someone please enlighten me?
Thanks,
smy

The trick to make the [name, MAC address] permanent is to assign a static DHCP lease to each device. Otherwise, when the lease expires and the device is no longer active, the router forgets everything about it.
As for changing MAC address, you are correct, they shouldn't change.
If you have multiple "Android-xxx" devices they may be coming up in a different order, thus creating the appearance of changing addresses. Make a list of every active MAC address and attempt to correlate it to your devices. The next time you think one changed, look and see if it's on your list.
MAC addresses can be changed by the user on some devices, however this is typically only done to "play" with a network or circumvent security features.
Good Luck.

HH5 and static IP address question

I've been trying to set up static addresses for my devices and for some weird reason, when trying to set an address for one PC, the HH tells me the following:
The IP address entered conflicts with a device using the same IP address on your home network.
Please enter a different IP address.
Ok, seems fairly self-explanatory but after looking through the devices and dhcp table, it appears that no other devices have that IP address. How can I free up the address in question if I'm unable to locate what device has been assigned it please? It doesn't respond to pinging.
Thanks.
P.S - Can remember my previous frustrations with earlier models of the HH. Can anyone recommend a decent third party router that works well with BT Infinity please?

From what I can remember (I haven't used a Home hub in eons) the Home Hub's DHCP range is 192.168.1.64-192.168.1.253 (.254 is used for the router itself), so in order to use static IPs on your LAN, you would need to use 192.168.1.1-192.168.1.63 for your devices.
Don't forget that the subnet mask would be 255.255.255.0
I hope this info helps.

DNS and Static IP Address Question on Solaris v10 X86

I�ve recently installed Solaris v10 X86 and have two questions. The system is a Dell E521 with 4GB RAM and 1GB SysKonnect NIC, and internet is provided via a cable modem, that�s plugged into a Netgear router, and the Solaris 10 box is plugged into the Netgear router via a CAT5 ethernet cable.
1. I can connect to my router login page using the following URL:
http://192.168.1.1/start.htm and I can also connect to various web pages such as yahoo, if I first "ping yahoo.com" (on another machine that�s internet enabled) and then plug the web site�s ip address into the Solaris/Mozilla browser. So it appears that I haven�t been successful at pointing the Solaris x86 at a DNS server to resolve the DNS name.
2. I've purchased a commercially available software package and it requires a static ip address for this Solaris x86 server. If the ip address changes, it�ll stop working by design and require that I reacquire the license file. When connecting through this Netgear router, how do I lock this Solaris v10 x86 server into a specific ip address? (the ip address floats presently when cycling my PC�s on/off) presently, and assume the Solaris box will too, usually through an ip range of 192.168.1.<1 through 5>

The NIC is a SysKonnect 9821 1GB Ethernet card. The drivers in Solaris 10 were apparently very old and didn't install drivers or configure/plumb when I installed Solaris 10, so I downloaded the
latest drivers (hard to find!), followed the instructions and got the NIC drivers installed and then plumbed.
My router's ip address appears to be 192.168.1.1 and in one of the articles I've read, there is a recommendation to create a file (touch) within /etc named defaultrouter and enter the router's ip address. I did this, and the file now contains:
192.168.1.1
I also read where another file called resolv.conf needed to be pointed to a DNS server, which in this case, according to my Netgear router, and according to ipconfig/all on another WinBox on the same network, also shows the same 192.168.1.1 address for the DNS, so I created that file too (wasn't there) and it contains:
nameserver 192.168.1.1
There is a host name file called hostname.skge0 and it contains one line:
INTHOST
There is a hosts file, and it contains:
127.0.0.1 localhost loghost homex86
192.168.1.3 INTHOST
There is a netmasks file, and other than the commented out lines, it appears to contain one relevant line:
192.168.1.0 255.255.255.0
There is a nsswitch.conf file and other than the commented out lines, it contains:

Finally, I've also seen some advice using the folling command (and I tried it):
"route add default 192.168.1.1" as an alternative method of setting up route table
The only other command I've tried is:
"ifconfig skge0 192.168.1.1 netmask 255.255.255.0 up" but I suspect that was redundant as the plumb command I used to get the NIC functioning earlier probably already provided what was needed.
Finally, on this small network, I ran an ipconfig/all on a Windows based PC, to see what network settings were reported through the wireless connection, and this is an excerpt of that information:

Port Forward and IP address question

I am configuring my father's computer so that I can "see" his screen. He's on a different network, using a mac with a wireless router. He enables remote desktop login, I use Chicken of the VNC software on my mac to see and control his computer.
Here's my question, when I set up his router to forward the ports so this will work, do I use the ports for apple remote desktop or VNC? (The ports overlap (5900) but are different.)
Also, which IP address do I enter into Chicken of the VNC? His router IP, his static IP that we assigned or his computer's IP.
Thanks for the help,
Rob

ok, but in his prefs for apple remote desktop, it gives the static IP address that we set as the address other people can use, so... any thoughts?
You use that private address if you are in the same subnet as his Mac. That is the address you enter into the port forwarding settings on the router because the router needs to send requests received on the public IP address to that unreachable private IP address.
When you are on the internet, you can't reach that private IP address.

4506 & SUP V Management IP address question.....

Hello all, I have two questions. The new 4506 SUP V engines don't have the good old SCO interface that I'm used to. So, since it's running an IOS now instead of the old CATos, I figured I'l create a new vlan and then make it the management IP address by using the 'MANAGEMENT' command (like in the old 2900's). Well, that didn't work either, so my question is...on what int. do I configure the mgnt. IP address?
-thank you....

Russ,
In the current version (up to 2.1) the Management IPs for blades are required to belong to the same subnet as the Management Interfaces of the Fabric Interconnects. This is due to the way we proxy the KVM request from Management Interfaces to the Blades CIMC. In a future release we're investigating breaking the blade IPs into their own subnet/VLAN but this is a ways out - no committed date at this time.
We understand this puts quite a requirment on the size of the Management Subnet, but with proper design it shouldn't be much of an issue.

Robert

WAAS Network Module IP address question

I've read the instructions for configuring a WAAS Network Module but I don't understand what IP space I'm suppose to use.
https://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v403/module/configuration/guide/wsnmecfg.html
My 2821 has g0/1 as the LAN connection and s0/1 as the WAN link
g0/1.1 - 10.1.1.1 /24
g0/1.4 - 10.1.1.4 /24
s0/1 - 192.168.1.1 /30
Do I need to allocate a new subnet for interface service-engine1/0? Or can is be an IP address in my 10.1.1.1/24 subnet? What's the best practice?
If it's a new subnet then I assume I need to add it to eigrp, right?
Here is the sample from the Configuration Guide...
interface service-engine1/0
ip address 10.0.0.20 255.255.255.0 <--- does this have to be it's own subnet, what's best practice?
service-module integrated-service-engine ip address 10.0.0.30 255.255.255.0 <-- this has to be in the same subnet as above, right?
service-module integrated-service-engine ip default-gateway 10.0.0.20 <-- is this always the "int service-engine1/0" IP?
Sorry for the shotgun question approach. Thank you in advance.

Hi Tod,
The most common scenario is to allocate a new subnet for the module. Since the module will need IP connectivity to the Central Manager, you should advertise it via EIGRP (or whatever routing protocol you are using).
Here are the answers to your command specific questions:
ip address 10.0.0.20 255.255.255.0 <--- does this have to be it's own subnet, what's best practice?
> See above. The most common scenario is to allocate a new IP subnet.
service-module integrated-service-engine ip address 10.0.0.30 255.255.255.0 <-- this has to be in the same subnet as above, right?
> Yes. This is the IP address that is assigned to the NME-WAE.
service-module integrated-service-engine ip default-gateway 10.0.0.20 <-- is this always the "int service-engine1/0" IP?
> Correct.

Zach
