Does Aironet 1100/1120/1130 support for IPv6 ?

Experts,
I find much document, but not found information about whether those support for IPv6 e.g. dual-stack like newer series.
Has anyone used to test on those?
Thank you in advance for any info,

Hi,
When working with WLCs if you are running code 7.2 you will be able to support IPV6 but this code is only supported by the latest model of WLCs and the APs that are supported under this code.
On previous WLCs models that support up to code 7.0, the WLC only handles IPV6 pass through after code 6.0 since it does not support native IPV6.

ACE module support for IPv6 ?

what is the latest on IPv6 support for ACE module? I saw something saying 2HCY10, but that's where we are now. Any documentation pointers to current compatability and or roadmap are greatly appreciated.
thanks
Bob O.

As mklemovitch described in the following thread, IPv6 will be
supported on ACE30 module but not in the initial release.
There is no plan for ACE20 module.
https://supportforums.cisco.com/message/3192517#3192517
I'm not sure but maybe around Q3 CY11 or later.
I cannot see the documentation regarding this feature on CCO.
I would suggest to contact your account team for details.

Support for IPv6 DHCP or RDDNS

Hi,
I'm deploying IPv6 on our company and found out there is not possible way to automatically get DNS servers for IPv6 for mac computers, since it doesn't support dhcpv6 or the extensions for RA in stateless configuration mode.
Any word on when are this features going to be available?

It's really rather ridiculous DHCPv6 isn't implemented in OS X yet. I can (possibly) understand this for 10.4 and 10.5 but 10.6 is going to run into IPv6 deployment scenario's and should be able to handle all cases. I hope to God 10.7 has decent v6 support throughout OS X.
As far as I know, the dhcp-client used by OS X is the KAME project client, now known as WIDE-DHCP which does have support for DHCPv6 and has so for a long time. Why Apple is so reluctant to include this feature in both iOS and OS X is quite the mystery.

ISE: support for IPv6 DACL's

Hi,
Does anyone know if/when ISE will be able to push out IPv6 dynamic acl's? I have not managed to find any information on this other than an old post here: https://supportforums.cisco.com/discussion/11795676/ise-support-ipv6-dynamic-acls
Thanks,
Phill Macey

It's not supported as of the current ISE 1.3.
I've heard it is planned for a future release but there's no announced or committed date as of yet.
If your're working with a partner or Cisco account manager, be sure to officially request it if it's important to you. Customer requests help build the business case for prioritizing the features.

ACE - Support for SSL Server Name Indication (SNI)

Hi,
I have the question if Cisco ACE currently or in the future supports SSL SNI (RFC 3546 or 4366). You run into that problem when moving SSL termination from a server that supports having multiple different certificates bound to the same IP and acting on the different domain names (SNI). Currently I do not see any chance how to build that on the ACE. In case it is definitely not supported, is there anything on the roadmap for that?
Thanks and best regards,
Daniel

From what I understand SNI is largely reliant on client support. It is just an extension of the TLS SSL protocol. One of our Escalation Engineers wrote up a pretty good post explaining SNI.
http://blogs.technet.com/b/applicationproxyblog/archive/2014/06/19/how-to-support-non-sni-capable-clients-with-web-application-proxy-and-ad-fs-2012-r2.aspx
"SNI is an extension to the TLS SSL protocol that allows the client to include the Hostname the client is connecting to in the SSL Client Hello. A server can then use the SNI header to determine which certificate to serve to the client. A key benefit
of SNI is that is allows a server to host multiple certificates on the same IP/port pair instead of needing an IP per certificate (assuming you are using port 443)."
A few questions I would have is what client and browser combination have you attempted on this? Also, are you using a wildcard certificate on your Web Listener? Have you taken network traces to see if client is sending SNI? Ian does a good job of explaining
how to do that in his blog post.

Support for IPv6

Hi all,
As i understand that IPv4 may run out as early as nxt mth. And we may need to use IPv6. Hence i would like to know if the following devices support IPv6.
1)cisco asa 5510/5505
2)cisco pix 515e
3)cisco 2811
4)cisco 1811/1841
5)cisco 837
6)cisco 1720
How are you planning the transition from IPv4 to IPv6? Pls advise, thks in advance.

The whitepaper link lists software version information you'll need to know to determine if your devices are currently IPv6-capable. If they are, you should check out the IPv6 resource center at http://www.cisco.com/ipv6 for more on addressing, configuration, advanced IPv6 features, managing an IPv6 network, etc.

Support for IPv6 Router Advertisement Option for DNS Configuration RFC 5006

Hi everyone, do you know that whether Cisco routers support “IPv6 Router Advertisement Option for DNS Configuration RFC 5006” currently, is there any roadmap for this support? Thanks for your help!

No, this is not currently supported, and the last I heard, there is no roadmap for this until it becomes a standard (as opposed to being experimental).

GRC Controls Suite Support for IPV6 and IPV4

Dear all

IPv6 support for oci

Hi,
I am using oci.dll 10.1.0.4. I would like to know whether it supports IPv6?
In all forums related to IPv6 support for oci I find it redirected to IPv6 support Oracle database 9i and 10g (which do not support IPv6), but my question is whether the interface library support IPv6?
Thanks in advance.
Regards,
Richa

No, there is no support for IPv6 in any part of 10g; you need at least 11.1.0.6. See Meatlink Note 579222.1.

IPv6 Multicast support for service providers 6PE / 6VPE

Hi,
Can anyone comment on the current state of development for IPv6 Multicast support for Service Providers who are using 6PE or 6VPE in their MPLS core.
(6PE - SP is running MPLS in its IPv4 core, it uses IPv6-enabled provider edge (PE) routers to transport IPv6 traffic over an IPv4-only enabled core. 6PE does not support VPN,s it just provides a mechanism for tunneling IPv6 packets from ingress PE to egress PE routers)
(6VPE - refers to a PE router capable of supporting IPv6 VPNs. A 6VPE solution can be used to provide IPv6 based layer 3 VPN services in a similar way to IPv4 based Layer 3 VPN services.)
My understanding is that 6PE and 6VPE solution are unable to support IPv6 multicast traffic.
Any further information on configuration, design or development work in the pipeline would be gratefully received,
kind regards John

Hi John,
From our question I understand you are sking about the MVPN support for IPv6 multicast. It is actually supported on the XR platform as of now. Please refer:
http://www.cisco.com/en/US/docs/routers/xr12000/software/xr12k_r4.0/multicast/configuration/guide/mc40mcst.html#wp2890031
I hope this helps.

Hi Bob,
Yes, this info got burried. Basically, it's a tool for building LabVIEW-based software products. It is highly flexible/extensible and tries to fill the holes left by LabVIEW's built-in Application Builder. Here are some good links to more info:

IPv6 support for Mail/Postfix

After adding and enable an IPv6 address, how do I get xserver to start listening for ipv6 mail requests?
Looking at the main.cf I see:
inet_interfaces = all
But running netstat -an | grep 25 I don't see tcp6?
tcp4 0 0 *.25 . LISTEN
Just to check sanity, I can ping it via ping6.
And ssh is listening:
tcp4 0 0 *.22 . LISTEN
tcp6 0 0 *.22 . LISTEN
Is there something more missing?

You need to edit /etc/dovecot/dovecot.conf
You need to change your listen command to the following:
listen = *, [::]
Please note that the above command needs to have brackets around the colons - for some reason the forum software is deleting them.
Also, I found that not only did you have to change the listen command at the top of the configuration file but also change the listen command to the above within the IMAP and POP3 (I only edited the IMAP since I don't use POP3) specific configurations that are found further down in the file.

Network Connectivity Status Indicator for IPv6 works wrong in Windows 7 and Windows 8

Hi Folks,
I am working on testing Network Connectivity Status Indicator for IPv6 in Windows 7 and 8.
Waht is "Network Connectivity Status Indicator(NCSI)" you can refer to https://technet.microsoft.com/en-us/library/ee126135%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396
I found that even if Network Connectivity Status Indicator detect IPv6 connection to http://ipv6.msftncsi.com/ncsi.txt failed.
Windows IE still use IPv6 to connect to website first, rather than stop using IPv6 and to use IPv4.
It will cause IPv6 fallback to IPv4 problem, that's 21 secs and 7 secs delay for fallback in Windows 7 and 8.
Does anyone suffer the same problem?
Or someone know how this works?
Thanks!

Hi Roger_Wang0214,
"Windows IE still use IPv6 to connect to website first, rather than stop using IPv6 and to use IPv4."
By default Windows prefers IPv6 over IPv4,we can manually configure the IPv4 prefer over IPv6 if it has result in any troubles.
Here is a link for reference :
Resolving Internet connectivity issues after World IPv6 Launch (June 6, 2012)
https://support.microsoft.com/en-us/kb/2533454
"The "Prefer IPv4 over IPv6" Fix it solution will configure your computer to prefer IPv4, instead of IPv6. By default, Windows prefers IPv6 over IPv4. If you are having problems using IPv6 to connect to some websites, this may resolve the
problem."
For a Windows 7 machine ,we can try the following fixit tool to configure IPv4 prefer over IPv6 .For a Windows 8.1 machine ,we can configure it referring to the manual part .
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents
If the DisabledComponents entry is unavailable, we can create it (DWORD (32-bit) Value).Then set a value with "0x20"to prefer IPv4 over IPv6 by changing entries in the prefix policy table.

Airport Utility 6.0.0 breaks support for my Airport Express

Computer updated to Airport Utility 6.0 but that breaks support for my Airport Express. When I try to access the Airport Express it tells me I have to download Airport Utility 5.6 - but I can't find that anywhere on the Apple sites to download!

My catch-all list of Airport 6.0 & Firmware 7.6.1 problems:
~~~~~~~~~~~~~~
I've compiled a catch-all list of problems and changes with Airport Utility version 6.0 and FW 7.6.1. Some of the items may be relevant to this thread.
THE PROBLEMS WITH AIRPORT UTILITY 6 AND FIRMWARE 7.6.1:
Introduction: If you find AirPort Utility v6.0 too limiting or strange, you can ALSO install AirPort Utility v5.6, released alongside v6.0, to maintain all your previous capabilities. It works fine with both Airport g and n devices.
PLEASE NOTE: According to Apple you must FIRST install Airport Utility v6.0 in order to access and install Firmware upgrade 7.6.1. Do that first. THEN install Airport Utility v5.6 and use it instead if you prefer. HOWEVER: Another user has informed me that they were able to use Airport Utility v5.6 to install Firmware v7.6.1 without any problems! This would mean anyone can avoid Airport Utility 6.0 entirely if they chose.
~~~~~~~~~~~~~~~~~~~
1) According to Apple's documentation, Airport Utility version 6.0 is ONLY for Mac OS X 10.7 Lion. It is NOT for 10.6 Snow Leopard. If you accidentally installed v6, you'll have to dig around in Apple - Support - Downloads for the previous relevant version for your devices and OS version. Here is the relevant page:
http://support.apple.com/kb/DL1483
2) The HELP for Airport Utility has been updated. When you first access it you may well be looking at the old Help. It is supposed to update itself spontaneously over the Internet. It took a couple minutes in my case. Be sure you are looking at the NEW Help before you start using it. One way to tell is that the list of help topics essentially doubles from what there used to be. Also, the very first topic in the NEW Help should read:
"Set up an AirPort device > Set up a new AirPort Base Station or Time Capsule"
3) The HELP has some WRONG information. Here we go:
3a) There is NO "Enable Guest Network" setting. You CANNOT create a guest network or name it or give it any settings. Why this is still listed in Help, I have no idea. Why the setting is gone: This is most likely because the technology behind guest networks, WPS, has been thoroughly CRACKED in the wild. Google "WPS cracked" for lots of documentation of the situation. It won't be resolved soon.
3b) I can't find any 'Setup Assistant". Everything is now manual. This is not to say that there isn't a setup assistant that appears when you FIRST set up your Airport device. I don't know.
4) After installing Airport Utility v6.0, there is no indication of the accompanying firmware update until you decide to run the new version. Even then, you have to click on the big icon of your Airport device and notice an 'Update' button about halfway down the popup window. You then have to assume that this button is telling you to update your firmware.
5) After you update your Airport device's firmware, you may well discover an ERROR subwindow popping up inside Airport Utility that says:
"An error occurred while updating the firmware. -6721"
Don't panic! All you need to do is go into your Wi-Fi settings, either in your menubar or the Network preferences, and turn OFF Wi-Fi, then turn ON Wi-Fi again. This is part of a long standing bug in Lion's Wi-Fi with which I bet you are already familiar, certainly up through Lion version 10.7.2.
6) Miscellaneous changes in Airport Utility 6:
6a) The keyboard command to manually change your Airport devices settings is GONE. You have to click the little 'Edit' button after clicking on the big icon for your device.
6b) There is no longer any summary window for your Airport device. You have to instead click on the big "Internet" icon for related data, then click on the big icon for your Airport device for local settings data.
6c) There is no longer any HELP advising users to EXPORT their settings. (The Help only talks about Import of settings). BE SURE TO EXPORT YOUR NEW SETTINGS! I did this immediately after both updates.
6d) MAC address filtering for Airport devices is GONE.
6e) All references to IPV6 anywhere are GONE. I have to assume the IPV6 settings are now entirely working and entirely automatic. Let's hope so.
6f) Signal and Noise data and graphs are GONE. Use Apple's Wi-Fi Diagnostics app instead. Apple have hidden it here in Lion:
/System/Library/CoreServices/W-Fi Diagnostics
6g) In order to access the menu items in Airport Utility, you have to first click on the big icon for your Airport device.
--> No doubt there are other changes, oddities or bugs related to these changes. But this is what I came up with during a cursory strafing of the software.
