Intermittent ping drop on MPLS VSAT link.

We have a client connected through VSAT. I am at Service Provider place and client is connected through VSAT link in MPLS cloud. I am facing intermittent ping drop in the tunnel interface terminated at other end. Pl help how do i check the trouble shoot the problem.

actually you have configured ip mtu thats why you were not able to see on interface. If you change then mtu with only mtu command then it will be changed.
only MTU is realted to harware
ip mtu "IP MTU is used to determine whether a non-labeled IP packet forwarded through an interface has to be fragmented (the IP MTU has no impact on labeled IP packets). It has to be lower or equal to hardware MTU (and this limitation is enforced).

Face intermittent ping failure

Hi Guys, i face intermittent ping failure to a server which is monitor using IP Sentry. But when i do a sh logging buffer on my 6509 switch, i nvr see the port which is connected to the server "leaves". Does that means that the physical connectivity is still there but somehow we just lose the net connection.
I've also sh counters on the port, it state 25 linkchange. but i cant seems to look for the date/time it has linkchange.
Are there any other more commands to troubleshoot this issue.
Pls advise on this.. need help badly

When you know that the linkstate-changecount was 25, you can deduct that the link has stayed up when the counter still reads 25 at any given later time.
Please do a sh int or show port and verifiy your speed/duplex settings. This command will also give you the amounts of errored frames. Check these for changes, if they increase rapidly, you probably have a cabling problem or some other layer2 issue.
Furthermore, you should inspect the data-path between the NMS and the server.

Sudden Ping Drop from Default Gateway in VLAN

Hi,
We have a Layer3 Switch 3560 and we have configure multiple VLANs along with SVI on it. We have then cascade layer2 Switches (Cisco 2960) with 3560 by Trunk links. Now we are facing problem on one VLAN that users are in specific VLAN sudden get ping drop from their default gateway (SVI on Cisco 3560) and this problem is not come with all users in that VLAN as just few users in a single time face this problem. When we unplug the systems for few second and reconnect then problem get resolved for few minutes till hours.
Kindly guide me to resolved this.
Regards,
Arshad

I have also clean the arp cache on users systems by using "'netsh interface ipv4 delete arpcache" but in vain. Now i have perform the below steps and operation is working fine since last 20 hours approx.
1- Change the First Casade Switch Cisco 2960.
2- Remove EtherChannel and Change the Backbone port on Cisco 3560 and Cisco 2960.
3- Connect both switches with single backbone Gig Port.
4- IOS Version on previous Cisco 2960 switch was IOS 12.2(50)SE3 and the IOS Version on newly installed switch is IOS 12.2(50)SE5

Ping drop and general Failure on wireless

Hi all,
I am facing the ping drop and general failure error when I am connected to AP and try to do ping any IP with the ping size is 5500 bytes.Print screen shot is attached for your reference.
Product/Model Number : AIR-AP1242AG-A-K9
Regards
Ali Raza

yes that is what I mean. And you cannot figure out if this is happening or not. Don't rely on the wireless connection icon on windows.
It can be possible that your wireless adapters notices that the RF is busy and there were a few packet drops so it reconnects quickly. It's usually transparent to applications but if you are running a ping at that time ...
In any case, conclusion is : check your RF environment. How many APs around ? a lot of traffic ?

Unable proxy ping using CISCO-PING-MIB in MPLS VPN ?

using CISCO-PING-MIB in MPLS VPN ?
In CISCO-PING-MIB.my document, wu can use the CISCO-PING-MIB to
Proxy ping the hosts in the MPLS VPN (vrf).
But when i do it, router will return the message:
errstat =12; errindex = 1(ciscoPingProtocol).
If Router isn't configed vrf, can proxy ping.
If set the error vrf name in snmp packet,
errstat=10; errindex=8(vrfname)
Do Cisco Support Proxy ping with vrf???

sorry, i don't use unix station, i program to send snmp messages.
parameters:
ciscoPingProtocol = 1(IP);
ciscoPingAddress =x.x.x.x;
ciscoPingPacketCount=
ciscoPingPacketSize=
ciscoPingPacketTimeout=
ciscoPingDelay=
ciscoPingEntryStatus=4;
ciscoPingVrfName="vpn1";
The parameters is right, because when i don't use ciscoPingVrfName, i can
ping the address.
But i set the ciscoPingVrfName="vpn1", the error is received.
thanks.

Intermittant wifi drop-out on IMac 21', latest model?

I have an intermittant wifi drop-out on my IMac. This is the latest version IMac purchased just over 3 months ago!
The drop-out appears to be similar to wifi turning itself off and then back on.

Aironet 1130 AG Ping Drops.

Hello Friends,
We have 5 Access point in our network. recently we discovered ping drops in all access point. the pings dropping randomly. sometime one request time out or three times.
All APs are connected with POE edge switch.For test, we attached with other Core switch with power adapter but again same problem. We created different VLan & tried but same result.Even we upgraded OS to 12.4(25d)JA2
We tested same AP with other company network & there its working without any drops.
We are facing this issue since one month & there is no changes in network configuration.
Please advice on this problem.
Thank You..

We tested same AP with other company network & there its working without any drops.
So when you say this, to me it's no change in the AP configuration, but your just connecting it to another network and it's working fine. So that being said, looks like a meteors configuration issue not an issue.

AirPlay Mirroring from Mac to Apple TV intermittent sound drop-off

I can't stream iTunes or Spotify to my Apple TV without getting intermittent sound drop-out (say every 30 seconds) when I use AirPlay mirroring through my Mac. This odd thing is streaming through my iPad or IPhone to Apple TV is perfectly fine; so is using my Mac to stream to my Sonos speakers. I can even stream iTunes pefectly fine through only the Apple TV alone - so it's nothing to do with my broadband connection
I have today performed upgrades to the Apple TV and my Airport Express firmware but the problem persists. Anyone else experiencing this or found a solution?

Hi, same here for me. Using AirPlay for streaming music from my Mac Mini (iTunes latest version) to my ATV2 (software latest version) has intermittent drop-outs (about every 10 to 15 sec for 5 to 10 sec). At the same time streaming to my Airport Express station in the kitchen works fine. Using the VOX player streaming from the Mac to the ATV works fine, only that I can only stream to one destination. Tried streaming from iTunes to ATV only, the problem remains. Streaming video - even HD - works fine. Using the ATV to select music from my Mac's iTunes library works fine, too. Still I want to stream from my iTunes on the Mac to several destiations including the ATV. Seems to me to be a problem of iTunes. I think the effect appeared after an update of iTunes or OSX, because it had worked fine before, already.

MPLS TE - Link and Node Protection

Hi Guys,
Just revisiting an old topic again - MPLS-TE Link and Node Protection.
Is it enough that the backup path (facility backup as supported by IOS) just merge on any LSR of the protected LSP? It does seem to be that way. For example, consider the following topology -
R1-------R2-------R3------R4------R6
|_____R5____|
The Primary LSP is setup with explicit path R1-R2-R3-R4-R6 and requesting Link-Protection.
R2 protects the link R2-R3 with a backup LSP which has an explicit path R2-R5-R4. The backup LSP merges on the Primary LSP but R4 is not the next-hop to R2 protecting the primary LSP.
This works in my testing but my understanding was that for-
Link Protection - the backup LSP must be terminated on the LSR which is next-hop to the LSR protecting the primary LSP
Node Protection - the backup LSP must be terminated on the LSR which is next-next-hop to the LSR protecting the primary LSP
Your thoughts?
Regards,
Amit.

NHOP Versus NNHOP Backup TunnelsMore than one backup tunnel can protect a given LSP, where one backup tunnel terminates at the LSP
’sNNHOP, and the other terminates at the LSP
’s NHOP. In this case, the router chooses the backup tunnel thatterminates at the NNHOP (that is, FRR prefers NNHOP over NHOP backup tunnels)

How can I insert a spreadsheet containing drop down boxes and links to other spreadsheets into a keynotes slide? Please help :(

How can I insert a spreadsheet containing drop down boxes and links to other spreadsheets into a keynotes slide? Please help
I need to retain all the formula's and the sheets these formulas are linked from.

Have you considered switching out of Keynote and over to your spreadsheet program when you get to this slide? If you launch the speadsheet program before Keynote you can switch using Command-Tab. You can then switch back into Keynote when you are done.
I realize that this is not what you were looking for but I don't think it is possible to do exactly what you want.

A desktop is failing to join in Domain over a VSAT link. Error: Network path not found.

Dear Friends,
Facing an issue for adding a desktop in Domain over VSAT. When I say enter after typing the domain name which i want to join. I am asked for User name and Password. After User name and password is entered it waits for a long
time and then it gives an error as Network Path not Found. I am pretty surprised why is it happening like that.
In hosts file too I am mentioning the IP of the DC at my Data Center.
I have another site over VSAT which has worst latency and more RTO's than this one, but on that site I am able to add a desktop in Domain. I don't have domain controller at the remote site which is connected by VSAT.

Please do not hardcode the domain IP address in your HOSTS file. That will just create issues.
Please make sure that your client computer points only to internal DNS servers for DNS resolutions.
You can use NSlookup to make sure that DNS resolution for your DCs A and SRV records are working properly:

Also, make sure that you have no connectivity failures between your remote site and the one having your DCs using
ping: http://social.technet.microsoft.com/wiki/contents/articles/30110.ping-for-beginners.aspx

SharePoint Online Drag and Drop to Quick Launch Links

Hello,
We're using a SharePoint document library to store invoices and an approval workflow to manage the approvals for payment. Once an invoice is approved and paid, they move the invoice into a Paid subfolder. Because there are a lot of invoices, the view
stretches across multiple pages. When they're not on the first page of the invoice list, they can't use the drag and drop functionality to move the invoice into the Paid folder because the Paid folder only shows up on the first page of the list.
I would like to be able to add a link to the Paid folder to the links on the left side of the window. I can add the link, and it works in that if you click the link it takes you to
Shared Documents\Paid. But if you try and drag a document to that link, it wants to place it in the root Shared Documents, giving you an error message that the file already exists in that location.
How can I create a quick link to a subfolder of Shared Documents that also allows drag and drop functionality?
Thanks,
Adam

Hi Adam, here are a few solutions:
1. Use "Open with Explorer."
2. Use the Content Organizer to automatically move the documents.
3. Create a workflow to automatically move the documents.
4. Create another view or library on the same page with the Paid folder in it.
5. DON'T USE FOLDERS!
(sorry, they're a big pet peeve of mine because of all the problems they create. They're also completely unnecessary with only one exception.)

Selecting the XML data from a drop-down menu or links

Hi, I have this page:
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/volckinv.html
There are prints of lemons/limes and prints of oranges. I
want to have the visitor select which kind of fruit from either a
drop-menu or from two links that look something like this:
Lemons/Limes | Oranges. Looking at other help docs I found the
region/state mapping demo at
http://labs.adobe.com/technologies/spry/samples/data_region/StateMappingSample.html,
and copied the code and tried to modify it. But I don't really
understand the technical shorthand of the help docs (an ongoing
problem I have with the Spry documentation) and I couldn't find the
XML docs that the region/state mapping demos are based on so I
couldn't see how they were set up.
I got as far as this: nothing loads initially when you open
the page (I'd like the lemons to load), but if you select Oranges
from the drop-down menu you see the oranges, and THEN once you've
done that, you can select Lemons/Limes in the drop-down menu and
see those. I have three XML files I've been playing around with to
get this to work: lemons.xml, oranges.xml and inventory.xml, which
combines the two.
I also suspect region/state mapping might not even be exactly
what I'm trying to do here, but I can't figure out from the
documentation exactly what this thing I'm trying to do is called. I
know the photo album demo accomplishes something similar, and I
could do that, but it seems way more complicated than what I need
here (right?). Help will be appreciated!
Thanks,
Helen

I made a different test using the file
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/inventory.xml
and
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/volcktest.html
where I sent up the inventory xml form like one I found in the
Nested XML Data documentation where you have item ids and types, so
all the oranges and lemons are in one XML document (which I'd
prefer).
Here's an abbreviated version of the inventory.xml:
<inv_items>
<inv_item id="1" type="lemon">
<name>Lemons and Limes</name>
<title>Cedro Ordinario</title>
<plate>116a</plate>
<fullimage>pl116a.jpg</fullimage>
<tn>pl116a-2.jpg</tn>
</inv_item>
[and more lemons follow]
<inv_item id="19" type="orange">
<name>Oranges and Others</name>
<title>La Zucchetta Imperiale</title>
<plate>138a</plate>
<fullimage>pl138a.jpg</fullimage>
<tn>pl138a-2.jpg</tn>
</inv_item>
[and more oranges follow]
</inv_items>
What I'd like to do is display the names "Lemons and Limes"
and "Oranges and Others" and when you click on "Lemons and Limes"
you see only the thumbnails for lemons and limes, and when you
click on "Oranges and Others" you see the thumbnails for only
those. I'd like the Lemons and Limes to be selected when the page
is opened.
Help greatly appreciated!

Intermittent Sound Dropping When Streaming Audio

I've just step up my new Apple TV and streaming from my shared iTunes library over wireless network is great.. However when I stream using airplay on my iPad 3 or iPhone 5 the sound drops intermittently, as if the signal wasn't getting through, if you know what I mean! sometimes drops altogether and airplay on the device seems to switch off.
I can't see any settings that I could change even if I wanted to (or knew what to!) and it seems strange that it works fine from the pc but not from the other Apple products.
The wireless signal is obviously ok, or could it be the wireless bits n the iPhone/Pad are not as good as in the pc? Clutching at straws a bit here, hope someone out there can help.
Thanks.

Thanks for posting this because I too have the Pioneer VSX-1019AH and have just noticed this problem. I rarely listen to my iphone (ipod) through my receiver and this problem never occured before until yesterday.
I am experiencing a sound loss at random times, and it takes restarting the receiver, or disconnecting then reconnecting the iphone cable to get the sound back again, only for it to go off again in a few moments time.
Whilst the sound is off, both the iphone and receiver are continuing to play music because you can see the title of the tracks change on both devices. So where the fault lies is hard to tell but I'd say it's with the ios4.
I don't know whether Apple will provide any support regarding this problem but I do notice the receiver has been endorsed "made for ipod" which means it meets Apple performance standards.
