NAC Error Message in 4500 Switch
Hi There,
I have a 4507R core Switch running IOS version 12.2(31). I am trying to configure this switch for Clean Access; I have already configured the ACS server but when configuring the switch as a NAD and apply the "ip admission NAC" command on the interface level, I get the following error message:
% This config is not supported on this platform. Try configuring a new rule.
The NAC configuration I entered on the switch is as follows:
Switch(config)=ip access-list extended Interface_ACL
Switch(config-nacl)=permit udp any any eq 21862
Switch(config-nacl)=permit udp any any eq domain
Switch(config-nacl)=permit udp any any eq bootpc
Switch(config-nacl)=permit udp any any eq bootps
Switch(config-nacl)=permit tcp any host (antivirus ip address)
Switch(config)=ip admission name NAC eapoudp
Can somebody clarify to me the meaning of that error message and assist me whether my NAC configuration is alright?
Thanking in advance.
Regards,
Haitham
Hello All,
I just figured out the problem; you need first to configure the following commands before applying the ip admission command:
switchport mode access
switchport access vlan
Thanks to all.

Please help me with trouble shooting steps and also commands..........Hi,
Please ask the question in LAN SWITCHING community for speedy response but it looks like a message indicating that Switch is seeing a packet with src mac 00.00.00.00.00.00 which obviously is Invalid. Switch learns the mac from src in the frame and it is wrong. Looks like Mac-spoofing.

Hi.
Today I found one of my standby NAC servers is down. The power switch in front shows amber and the power supply behind too shows amber. When accessing through serial i see the following output. What could be wrong?
Regards
Prasanth GeorgeHi
I did remove the power and reconnected the power. Still it ends in ILO. Even if i continously keep pressing the power button in front, the light keeps remaining amber. Its model is 3140 CAS server
Any suggestions?

No Disk error Messages in PSE8
On and off I keep getting the following error message when I switch between Edit and Orgainzier in PSE8
and sometime other times. Photoshop ElementsOrgainzer.exe-No Disk There is no disk in the
drive. Please insert a disk into drive \Device\Harddisk4\DR4.
I have to hit Cancel 3-4 times to get rid of it.
What is this and how do I stop it? Tks. ALanI have recently experienced this message repeatedly in PSE6 running on Vista. I believe after either saving a file from PSE6 to a floppy in drive A or opening a file in PSE6 from an SD memory card in drive J. Resolved by recreating both situations then ensuring that i used photoshop to open files from and save files to the resident C drive before removing the floppy disk from drive A and using the 'safely remove hardware' function in Vista to confirm that it was safe to remove the SD card.
Following this procedure I have experienced no more 'no disk error messages' -
Error message of MAC flapping for CCM-UC installed in UCS server
Dear All,
I have a strange issue, I have the 2 UCS servers setup with CCM & unity Connection running on each server on PUB - SUB mode.
I'm getting following error message on the Switch where the UCS server Connects.
I'm unable to trace why we are getting this error message, There is no problem with accessing CCM or UC, also the Phone & Voice mail seem to working.

Has anybody expereinced such error before, Appreciate your help in tracing this error.
Thanks,
OliverHello,
I believe you'll get better answer at:
"https://supportforums.cisco.com/search.jspa?peopleEnabled=true&userID=&containerType=14&container=2003&spotlight=true&q=UCS"
my best guess is to check the LAN config on the UCS. It seems its trying to load balance the traffic in Active-Active rather than Active-Standby.

NI-PAL Service Manager Error Message
Hello Fellow LabVIEW users
I am getting error message everytime I switch on my computer as shown in the attached image file.
1) what is the NI-PAL? I could not find any help topics related to it.
2) Why is this error message shown? Could it be because I changed the PCI port for my GPIB card?
3) How do I overcome this issue? Is it a major problem?
Thanks

I have recently switched from MobileMe to iCloud and I now getting an error message in iCal :
"The server is currently unable to handle the connection due to a temporary overloading or maintenance of the server. If this continues you should contact the server administrator.
You may try to connect to the server again or take the account offline."
Since I am working from home and I am not on a server other than iCloud I don't understand why I am getting this message. (for 3 days). How do I fix it?TomCT60,
Is your MacBook using Mac OS X 10.6.8 as indicated in your post? If so you will not be able to fully integrate with iCloud.
iCloud and Snow Leopard, by Roger Wilmut describes what iCloud options are available for Snow Leopard.
If you are using Lion, go to iCal>Preferences...>Accounts, and delete/re-add your iCloud CalDAV server. -

I've downloaded iTunes 10.5 onto my iPod Touch, no problems but I've now got a constant error message on my laptop everytime I switch it on and access the internet. The message is "The procedure entry point xmlTextReaderConstName could not be located in the dynamic link library libxml2.dll"
This is the 2nd time this has happened. Last time iTunes Support called and we ran through a load of checks to no avail. The only option was to delete iTunes completely off my laptop and go for a new download of it. Can anybody tell me how to do it - didn't write it down last time, silly me, never thought it would happen again. Also sent an email to iTunes Support - waiting for a response.Maybe:

These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart. -
Had to switch MacBooks Now I'm getting error messages when I reinstall from backup
Had to switch MacBooks Now when I reinstall my adobe products onto the new computer I get an Error message (error #6) when I try and reinstall the programs (drag and drop) from my time machine backup onto my new computer. Im running what I believe is the adobe design suite CS 5.1 (It was purchased on disk in mid 2011) and the new computer does not have a disk drive to reinstall it that way
Restoring from Time Machine backups never works. It usually breaks the licensing mechanism.
