Hi,
I have configured port-channel Firewall ASA5515-X and stacking switch WS-3750X. Also firewall configured as failover mode. Problem is that my active firewall connected switch port show green and working but standby firewall connected switch port shows orange color.

Hi Ganesan,
I am proposing a design like this. You can have the STP in pvst mode and have a different priority set for the core switch to make it core a as root bridge. There is nothing wrong with your design you have made you core switch which will be physically down to your firewall... but in real it comes on the top of your firewall as well... But spanning tree conf should be done properly to achieve this... I have proposed my design which is pretty simple but easy for troubleshoot....
You can have your firewalls connected to core switch on the down and can directly connected to router on outside... always core a -->py fw--rtra will be the primary path... if anything goes wrong then secondary line will come in to picture....
make sure that your hsrp will have high priority to ur core a vlan conf for the access switches.....
Please do rate for the helpful posts.

Adobe Reader 8.1 causing slow down and crashes
Despite safely using 7.0 for years, when I updated to 8.1, my computer slowed to a snail's pace and froze frequently, more than hourly. I have definitely traced the problem to Adobe Reader 8.1 (8.1.2?)because the problems disappeared the several times I uninstalled it. I am now using 7.0 without any problems. Does any one have an idea what the problem is? Can I ever safely upgrade to Version 8?
The link to the Reader forum is at the top of this forum.

SLM248p web interface down and time reset
My SLM248P web interface keeps locking up (i.e. I get noting when I go to the IP address of the switch). I need to power cycle the switch to get the web interface to work. Also, whenever I reset the power, it goes back to Jan 1, 2000 (time). The swithc alsow seems to loose connections every now and then. And I keep getting a waring in the log that looks something like
"%STP-W-PORTSTATUS: e26: STP status Forwarding"I have the newest firmware. It has no impact on the situation.

VIF Bound Physcial Interface Down
Hi Guys!
We are trying to connect FI 6248 (UCSM 2.1.1a) to Brocade 6510 swtich(One FI to one of the two Brocade switches separately). The ports are configured as FC Uplink port and the FI's work in End-host mode. We created the service profile. After associating the SP to one of the blades the two errors occurs immediately:
VIF <number> Bound Physical Interface Down
VIF <number> Bound Physical Interface Down
and this relates to the 2 vHBAs created in SP. Is this normal situation if OS isn't already installed on the host? We can't configure SAN zone from the brocade side because we don't see any WWPNs of the configured vHBAs in the SP. We see only FI's WWPNs(as I think). NPIV mode is enabled from the Brocade side.
Can someone explain what can cause this problem?Sergey,
This is expected if there is no OS installed yet, see the possible reasons for the VIF down in this bug:

My iPad isn't working. I cannot follow a link in an email or connect to a game. It goes to a black screen then back to the main screen. Any idea what could be causing this?
Settings > General > Reset > Reset Network Settings
Perform a "hard reset" on the device by pressing down and holding the home button and the sleep/wake button for up to 30secs. until you see a black screen with the Apple logo, then release.
Then test to see if it solved the problem. -
I have Firefox set so that when I start up, I have it set so that it automatically goes to my home page. However when it freezes, which it does on a daily basis, and I have to shut it down and re-start, it automatically goes to the site which caused the problem in the first place.
If I was a hacker, I would probably find it quite fun to design a virus to reintroduce bugs after they had been exterminated - except that Firefox seem to have got there first.Here's how:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste '''sess''' and pause while the list is filtered
(3) Double-click the '''browser.sessionstore.max_resumed_crashes''' preference and enter 0 (that's a zero) and click OK.
When Firefox resumes after a crash, instead of resuming automatically, it will display a list of your previous windows and tabs and you can deselect problem pages.
(This assumes it wasn't a private browsing session.) -
Link down and Link Up Snmp trap C#
Hi i've configure my cisco router to receive the SNMP traps if the link goes up or down. However i found out that when i plugged out the cable i'm not receiving any link down on the network management system. Until i plugged in again the link will then show up or down state. May i know whats the reason why i can't receive the link down when i plugged out my cable?
If your router has only fa0/0 as active interface, then this would be the interface that the router would use to communicate with the network management system. However when you unplug that interface now the router has no interface that it can use to send the link down trap to the network management system.

I generate a Word document for reviewers. PrintedDoc properties include: Retain hyperlinks; Include drop-down text; Include expanding text.
Sometimes the Word 2010 document includes hyperlinks, sometimes it doesn't.
Popups typically don't work in the Word document.
Drop-down and expanding text appear intermittently in the Word document.
Has anyone experienced this and have a solution?
Thanks.
CarolI have never known hyperlinks to fail except in two situations.
The target topic is not in the printed document. Obviously it cannot link to something that is not there.
The hyperlink is a popup.
Not sure what you mean by popups not working in a printed document. If you mean the links to them break, then see above. Known issue.
I'm not sure why you are having the dropdown and expanding text problem as I have not known that to be an issue either. Is it always the same dropdowns that fail? Have you compared a good dropdown and a bad dropdown?
Take a look at Printed Documentation on my site.

Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ? how involved to replace fan ? cost ?
thanksNot directly, but if the CPU overheats because of incompatible software, that would cause slowdowns. Do not allow the computer to run if the fan is not working unless you wish to fry your motherboard. Please make a Genius Appointment and take it in for service.

downloaded songs from itunes and the internet went down and they will not play and also caused other songs already downloaded not to play what can i do
You can try a couple of different things. First - restart the iPod and see if the songs will play.
Restart the iPod 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.
If that doesn't help - delete the songs and then download them again. You can download purchased music again at no charge as long as you use the same Apple ID that you bought them with originally and as long as you live in one of these countries.
Previously purchased music is only available through iTunes in the Cloud in Argentina, Australia, Belgium, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Cyprus, Czech Republic, Dominican Republic, Ecuador, El Salvador, France, Germany, Guatemala, Honduras, Ireland, Luxembourg, Malta, Mexico, New Zealand, Nicaragua, Panama, Paraguay, Peru, Slovakia, Spain, Switzerland, the United Kingdom, United States, and Venezuela.
If you are running iOS 5 on the iPod - You can delete songs by swiping across the song in list view to bring up a red delete button. Tap the button to delete the songs. Download the songs again in the purchased tab in iTunes.

Unidentified traps and interface down alerts LMS 4.2
Hi all,
Sometimes we have unidentified traps in our log, we don't know where they come from.
In high severity faults we see an active alert with device name “Unidentified” event name unresponsive but with a certain ip address.
What are these alerts about? Can I filter them?
A second issue I have is that I get interface down alerts. But when we log on to the device, there is no interface down at all. We can also ping the device from the lms server at that time. I have been told that the admin state and operational state has to be up.
Thanks,
Best Regards,
JorisHi Joris,
Generic trap support is a new feature introduced in LMS 4.2 release. look at the below
document also.
http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_lan_management_solution/4.2/user/guide/lms_monitor/TrapFwd.html#wpxref13049
LMS 4.2 release onwards DFM will display any unprocessed traps comming from device in
fault monitor screen as unidentified trap under Inform alarm.
For the other issue , it could be a DFM database issue , try to REDISCOVER those devices in
DFM and see how it works
Thanks

Scrolling down and using links to anchors aren't in sync
This video shows a site I'm creating. I start in design mode. Then I click to preview. As I Scroll down and the page stops too soon. When I use the links to anchors it goes all the way down. How can I get the page to work the same when scrolling as it does when using links to anchors?
I noticed that when I use the links to anchors the bottom portion of the menu gets pushed down a couple of inches. That seems to be the problem. Why does using anchors do this and how can I fix it?You want to precompose your stills and the track mattes together. The composition should look like the stills with a rounded rectangle border. Then animate the composition.

Then untilk the noonroot is not associate the interface radio remanis in restet status protol down ¿is it?
My problem is that this Brigge working fine for a year ago but one day fails and I replace the bridge but the interface radio remain in status reset too¿can be that the extenal antenna is broken? and therfore no signal received by the interface and can not associate with root for it?
I try to put boths brigge close and test if interface radio is up and works fine .If works like this I think that is a problem with the extrenal anntena ( dipolo)
