Problem with VLAN Trunking within RHEL6.6 VM on Hyper-V 2012 R2?
Hello,
I'm wondering if there is a known issue with using a "trunk" mode interface within a RHEL6.6 VM? I found the following article:
https://technet.microsoft.com/en-us/library/dn531026.aspx
Where note 1 reads:
"For this specific RHEL/CentOS release, VLAN tagging may not work when used in conjunction with trunk mode".
I've been fighting with this for the better part of a day and can't figure out what I'm doing wrong. I have a RHEL 6.6 VM with two NICs. The first NIC is a standard access mode NIC - no problems there.
The second NIC has been set up as follows (via PowerShell):
$a=Get-VmNetworkAdapter -VMName "My VM"
Set-VMNetworkAdapterVlan -Trunk -VmNetworkAdapter $a[1] -AllowedVlanIdList 101-105 -NativeVlanId 1
Note that the physical switch and switchports are configured to send tagged packets for these VLANs as well.
I then set up a VLAN (eth1.102) based interface in the VM ... and never receive any traffic on it.
What I've observed is that:
A VM on the same physical host using the same virtual switch can communicate with the VM on the tagged VLAN
A pcap of the "eth1" interface (to which eth1.102 is bound) shows traffic for VLANs 101 through 105 arriving ... I just never see the traffic for VLAN 102 forwarded to the eth1.102 interface
An identical network configuration using Ubuntu 14.04.01 LTS works exactly as expected
It's this last point that has me wondering if the problem is with RHEL and not Hyper-V (or the physical/virtual switches involved).
I'm curious if anybody else has seen this behavior or, if RHEL 6.x is working for you, if you're using Intel or Broadcom NICs on the physical Hyper-V host?
Thanks,
This is indeed a known issue with RHEL. There's a bug open with Red Hat on the issue, and our understanding is that they have a fix in progress that will be part of a RHEL 6.6 update. You might inquire with Red Hat regarding
their bugzilla #1135347.

Problems with vlan and dot1q trunking port
Dear Folks,
i have problems with my AccessPoint Konfiguration.
Even when i set the Catalyst Port to trunk, i can only connect to VLAN 1 but not to VLAN 10.
and if i change the port to statik vlan 10 i can not connect to the ap but it works...

it would be fine if anyone could help me....You configure Layer 3 Mobility with WLSM. No trunking is required on the CAT switch. However, you need to set the switch port on the CAT switch as access port in VLAN 10.
Please post the WLSM and SUP720 configuration. Also, which VLAN do you want to access the AP?
The following URL may be useful for you to verify the configuration:

SG-300 28P switches problem with VLAN Data and Voice, working all the time as Voice VLAN
Hi Everyone,
Thank you very much for your help in advance. I’m pulling my hair to fix the problem.
I just got the new SG-300 28P switches. My Bios ordered for me. I did not know how it runs until now... not an IOS based. I really do not know how to configure it.
I have 2 VLAN are Data and Voice.
- Data VLAN ID is 2 IP 192.168.2.X/255.255.255.0
- Voice VLAN ID is 200 IP 192.168.22.X/255.255.255.0
- I created two vlans, in switch, Data and Voice.
- On the port number 28, it is trunk by default, so I add Data vlan ID 2 tagged.
- On the port number 26, it is trunk by default, so I add Voice vlan ID 200 tagged.
- On the port number 27, I add Data vlan ID 2 tagged for Data vlan out.
- Port settings No.1
I set it up as Trunk with Data vlan 2 untagged, and 200 Tagged (voice vlan). I plugged in a phone with a pc attached. But the PC will get to the vlan 200 to get the DHCP address, but no from vlan 2. The Phone works with correct vlan ip.
- Port settings No.2
Trunk with vlan 1UP, 2T, and 200T. The phone is even worse. Would never pick up any IP from DHCP.
- Port settings No.3
Access with 200U...of course the phone will work... and the PC could not get to its own vlan. Instead, the PC got an ip from the voice vlan. Not from VLAN 2.
I have Linksys phone I’m not sure if this help.
For more information I setup in switch,
- enable voice vlan
- set the port on auto voice vlan
- enable LLDP-MED globally
- create a network policy to assign VLAN 200
- assign this network policy to the port the phone is connected to.
I hope this information help to help me to setup Data and Voice vlans, to plug the phone to work with vlan Voice 200 (IP rang 192.168.22.X), from phone to Pc and pc work as Data vlan 2 (IP rang 192.168.2.X).I just got done setting up voice VLANs on an SF 300-24P and verified working. This was working with Cisco 7900 series phones connected to a Cisco UC setup.
Here's my sample config.
Note that I edited this by hand before posting, so doing a flat out tftp restore probably won't work. However, this should give you a clue. Also, don't take this as 100% accurate or correct. I've only been working with these things for about a week, though I've worked with the older Linksys SRW switches for a couple of years. I'm a CCNP/CCDP.
VLAN 199 is my management VLAN and is the native VLAN on 802.1q trunks.
VLAN 149 is the data/computer VLAN here.
VLAN 111 is the voice/phone VLAN here.
VLAN 107 does nothing.

Cisco/Linksys SLM224G SWITCH: Problem with VLANs
Hi!
I'm trying to set up VLANs in my racks. I have some knowledge about VLANs, but I still can't set it up in my way.
My situation:
I have PC which contains two virtual machines, which has to works as a routers between three networks: LAN1, LAN2, WAN. It's a bit complicated, but I'll try to draw it:
|-------------|
|----------------------------| | e1|-to-eth1-VM2-----WAN
|VirtualMachine 1 eth0|---trunk-VLAN1&2---|g1 e2|-to-eth0-VM2-----LAN2
|eth0=VLAN1 eth1=VLAN2 | | e3|-to-eth0-VM2-----LAN2 etc.
| PC | | SWITCH e4|
|VirtualMachine 2 | | e5|-to-eth1-VM1---wire-to-LAN2
|eth0=VLAN3 eth1=VLAN4 eth1|---trunk-VLAN3&4---|g2 e6|-to-eth0-VM1-----LAN1
|----------------------------| | e7|-to-eth0-VM1-----LAN1 etc.
|-------------|
gX = Gigabit ports
eX = 100Mbit ports
VMX = Virtual machine number
wire-to = patch-cord connection between ports on the switch
Schema of routing and logical visibility:
LAN1---VM1-----VM2---WAN
|
LAN2----------|
Important note is that LAN1 and LAN2 has to be separated (visible only through routers). WAN has to be visible only through VM2 for LAN2 and through by VM1 and VM2 for LAN1. It looks easy, but VLANs which I done on that switch seems to doesn't works.
I'm doing this like that:
Step1: VLAN Management / Create VLAN...
Creating VLANs from 1, 2, 3, 4 (numbers doesn't meters right now - I now that number 1 is restricted at the switch).
Step2: VLAN Management / Port to VLAN...
Setting up VLAN1 with ports g1, e5 (both tagged or untagged? - I haven't seen difference)
Setting up VLAN2 with ports g1, e6, e7, etc...
Setting up VLAN3 with ports g2, e2, e3, etc...
Setting up VLAN4 with ports g2, e1
Step3: VLAN Management / Port Setting...
Setting up port e1 to PVID4 (frame type=all I suppose, but what with "ingress filtering"?)
Setting up port e2 to PVID3
Setting up port e3 to PVID3
etc...
Setting up port e5 to PVID1
Setting up port e6 to PVID2
Setting up port e7 to PVID2
etc...
So, on that configuration and on that switch it doesn't work for me
I know that switch is seeing MACs from VLANs which are done by PC's, because when I get in "Admin / Dynamic Address" I can see MACs on correct ports and with correct VLAN ID. So the problem is to forward VLANs on their ports, next clear frames from IDs and let packets go (and back: take clear packets, add VLAN ID and send to gigabits ports).
Showed configuration is the one of many that I tried :/ but I think this one is the best one.
Or maybe I don't know VLANs as I think and that schema is impossible? Please tell me if I' doing sth wrong.
Regards
and waiting for any suggestions,
LucasYou need to make sure that your VirtualMachine can send tagged frames if the VMs share physical ethernet ports on the host.
I count 4 different LAN segments but you have only 2 physical ports on your PC (router).
And VM2 requires 3 physical connections according to the list below.
Depending on the virtualisation software you can maybe create the connection PVM1 to VM2 internally inside the PC (logical connection)
Are these the connections you require ?
VM1 --- LAN1
VM1 --- VM2
VM2 --- WAN
LAN2 --- VM2
Is this correct ? Will your PC, Virtualisation Software/Hypervisor tag frames with VLAn tags ?
If this is true I can help you configure the switch.

A problem with vlan.dat retrieval in the RME
Hello,
the customer has LMS 3.1 and he uses RME for the backup of config files and vlan.dat files from netwrok devices. It is working fine, but he has problem with backuping vlan.dat files from the following switches: Cat2960-8TC,-24TC, Cat2960G-24TC,-48TC,-8TC and Cat3560E-24TD-E,S. I downloaded the latest packages for these devices into RME. I changed the telnet timeout value from 32s to 70s. But this issue still exist:-( The running and startup config from these switches is downloaded without any problem. Is it a bug?
Thank you
Best Regards
RomanHello,
I tried it manually and the copy is working ( i had to create empty file in the tftp directory under CSCOpx):-( The error mesage is that ssh and telnet is not available and tftp doesn't support fetching of vlan.dat. But ssh is working on the switches (the running and startup config is fetched by RME without any problem from these switches). The credentials verifications is done with OK for ssh and enable secret for these switches.

Any one having problems with the calandar within the last two days?
Having problems with iPad 2 calendar , anyone else with this problem?
What kind of problems? I am having no issues. Have you tried quitting the app completely and then restart the iPad?
Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Or reboot the iPad?
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
If those don't help, post back with your specific issues. -
Problem with sip trunk between CCM and Huawei through Cisco ASA5520
Hello,
I have a next problem
During SIP conversation ASA is changing the ip address of CCM to corresponding name in ASA configuration inside the SIP packet:
To: <sip:443230282@Server_CCM1;user=phone>
ASA name configuration:
name x.y.z.h Server_CCM1
But it should be without any changes like that: To: <sip:[email protected];user=phone>. Because of that session cant be established. Remote SIP peer gives an error "Bad Request - 'Malformed/Missing URL"
When name was deleted in ASA "no name x.y.z.h Server_CCM1" we have no any problem with SIP initialization and call proccesing.
We are going to upgrade ASA from 8.2 to 8.3 and it seems that we will have the same problem because object will be created automaticly in new version (we are using a NAT) and we will not be able to delete an object like we did in version 8.2.
What configuration in ASA version 8.3 should be done to avoid this issue.
P.S Detailed debug from Huawei in attachment.
Thank you.Hi.
depending on your config, you might be hitting CSCta16361, this is fixed in 8.2(4)
if you can confirm it's still happening in latest 8.2 release, then a TAC case needs to be opened so investigation is done and a new bug is opened.
if you've tested 8.2(4) already and it's still doing the same, then a TAC Service Request should be opened for more investigation and possibly opening a new defect.
Best regards,
Fadi.

How to configure a port channel with VLAN trunking (and make it work..)
We're trying to configure a port channel group with trunked ports to connect a NetApp HA pair. We want to create two data LIFs and connect them to the switch stack. We are trying to create 2 data lifs, one for cifs and one for nfs that are on different vlans.
We want the same ports to be able to allow multiple vlans to communicate. (trunked)
These data lifs should be able to fail over to different nodes in the HA pair and still be able to communicate on the network.
What this means is that we have to connect 4 ports each for each node in the NetApp HA Pair to the switches and create a port channel of some type that allows for trunked vlans. When we configure the ports, the configuration is as follows (below):
We are only able to configure an IP on one of the vlans.
When we configure an IP from another vlan for the data lif, it does not respond to a ping.
Does anyone have any idea what I'm doing wrong on the Cisco switch?

LGS308 problem with vlan and multicast
Hello,
I have a LGS308 smart switch and am having problems putting multicast traffic on a specific vlan.
The switch is connected to a PC for management (vlan 1).
All ports are in acces mode, vlan 1 untagged.
I created vlan 2 and put it untagged on port 7 and 8.
Now, when I connect a multicast device (IPTV) on port 8, the switch becomes unresponsive and nothing works.
It seems the switch is flooded with multicast traffic.
Simply turning IGMP snooping on didn't help so I think it needs more configuration.
Is this a known problem?
ps: Once I have this simple setup running I'm planning for a more advanced setup with trunking 2 vlans (iptv + internet) to another switch over a single UTP cable. But first things firstYes it should!
I have changed the setup like this:
Switch 1
port 1 - access mode - vlan 1U <---> Internet
port 2 - access mode - vlan 1U <---> PC
port 7 - access mode - vlan 2U <---> IPTV source (IGMP)
port 8 - trunk mode - vlan 1T + 2T <---> switch 2 port 8
Switch 2
port 7 - access mode - vlan 2U <---> IPTV source (IGMP)
port 8 - trunk mode - vlan 1T + 2T <---> switch 2 port 8
With this setup, I can reach both switches from my PC.
However, multicast doesn't work. I don't get IPTV on switch 2 port 7. -
Hello,
recently I bought few of SPA112 gateways, and I have two problems:
1. provisioning using xml file; device is not using new vlan setting (other settings such as dialplan, line number, user and passwd are working correctly), what I'm trying to apply is identical to setting used in other Sipura devices:
<!-- VLAN Settings -->
<Enable_VLAN ua="na">yes</Enable_VLAN>
<VLAN_ID ua="na">127</VLAN_ID>
Also tried with putting above setting in <router-configuration> but no luck.
2. it seems that after putting gateway from web service to use vlan, it still sits on access. This is what I see:
VID VLAN Name MAC Address Port Type
127 vlan127 88-75-56-05-98-FA 26 Dynamic
499 vlan499 88-75-56-05-98-FA 26 Dynamic
port setting is vlan499 - untagged, vlan127 - tagged. I want it to use only vlan127. Any help would be much appreciated, thanks.
FW version:
1.2.1 (004) Jul 27 2012I managed to find how to set set vlan using xml, unfortunately it looks like this part of provisioning is broken on Cisco side.
Gateway created sample xml file in which part about vlans looks like this:
0
123 <- here is typo BTW
The part that is not working is , SPA doesn't respond to changes in this setting. is set correctly. -
Transparency problem with animated gif within AJAX overlay
Hello all,
I have designed and animated a loading spinner in Photoshop CS3, which needs to sit within an Ajax overlay, with transparency set to 75.
I tried exporting the spinner as an animated gif with a transparent background (using Save for Web), but it gave the animation a pixelated outside edge. Does anybody know how to remedy this?
As the Ajax overlay is semi-transparent, I tried exporting the animated gif with a black background and transparency set to 75%. I ticked the transparency box in the export window, but once it is loading in the Ajax it doesn't seem to be transparent (see here: http://www.chrisgartside.co.uk/flash/Screenshot.jpg)
Any help is very much appreciated.
Best wishes,
ruth.I forgot to mention that the Ajax pop-up is fired up from a Flash gaming applet.
Thanks very much in advance.

Problem with text formatting within a table in Adobe Forms
Hi all,
I have a table on a non-interactive Adobe form (which is a copy of the standard expense form PTRV_EXPENSE_FORM. The table in ABAP has a text field with CHAR50. On the form, the text field has a width which allows approximately 35 characters. Therefore the text wraps onto a second line. My problem is that the text is not formatted and words are just split randomly.
For example:
The fox ran across the fields and into the woods.
would be output as:
The fox ran across the fields and i
nto the woods.
How can the text be formatted to only output complete words?
I have tried defining the textfield as text only and rich text, but nothing changes the output.
Interestingly, even if I change the font size from say 10 to 8, the text is output the same, even though there is enough space for at least one more word on the first line.
Has anyone else come across this problem?
Thanks,
PatriciaHi Syed
The table is IT_RECEIPTS_ADD_INFO, field VALUE_CHAR. In the form it is called Receipts_addl_info.
I have just found out that the data is being re-formatted in the interface. That caused the problem. Many, many thanks for your help.
Best regards

Problem with shuffling tracks within playlists
I'm having trouble shuffling songs within playlists. I have an iPhone 5s with iOS 8.1.2.
If I open a playlist and press 'Shuffle' (or the Shuffle icon) above the first song, nothing happens--the playlist will not play, and I'm unable to play any of the individual songs within the playlist (the songs in the list will gray-out briefly when clicking on them).
If I start a playlist and try shuffling from the 'Now Playing' screen, only the current song will play. For example, I hit 'Shuffle'--"Shuffle All' is highlighted but '1 of 41' becomes '1 of 1.' If I then hit 'Shuffle All," '1 of 1' becomes '0 of 0.'
Thus far, the only way I can shuffle a playlist is to ask Siri to do it (and she doesn't always understand the playlist names).
Am I doing something wrong, or is there a bug here?
Thanks.It seems to occur more frequently lately. You can still add songs by right-click < Add to Playlist, although this is not as convenient as drag-n-drop. Hopefully it will get fixed soon.

Problem with complex dataBinding within concat
Im trying to create a link with a databound onClick attribute like so:
<link ....>
<boundAttribute name="onClick">
<concat>
<fixed text="submitForm('result',0,{'event':'action','action':'"/>
<dataObject select="defaultAction" source="fti:search"/>
<dataObject select="##','index':'%index%'});return false;" source="resultRow@fti:search"/>
</concat>
</boundAttribute>
</link>
fti:search is a dataObject that returns another dataObject for the selectString resultRow. The resultRow dataObject should then be called with the selectString ="##','index':'%index%'});return false;
However the resultRow dataObject is never called with that selecString.
I also tried writing:
<fixed data:text="##','index':'%index%'});return false;@resultRow@fti:search"/>
but with the same result.
I'm using this syntax for many other controls, but for the text attribute of a <fixed> element it doesn't seem to work.
So how can I do a complex dataBinding within a <concat> element?
Thanks,
GuidoHi Guido
I think you need this
<dataObject select="##,'index':'%index%});return false;" data:source="resultRow@fti:search"/>Cheers

markyHave a look to HttpURLConnection object (in java.net package). A example of the code :
URL url = "http://myServer/myJpegServlet";
HttpURLConnection uc = (HttpURLConnection) url.openConnection();
uc.setDoInput(true);
uc.setUseCaches(false);
uc.setAllowUserInteraction(false);
InputStream dataIn = uc.getInputStream();
byte[] buf = new byte[512];
while( (dataIn.read(buf)) != -1 ) {
//Do what you want with the data
datain.close();
uc.close;
Hope this helps!
