Cisco Configuration Professional Compatibility With Windows 8


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

Cisco Configuration Professional Compatibility With Windows 8

Windows 8 came with internet explorer 10, this explorer is not compatible with Cisco configuration professional 2.6, so when you run the program it will not show full screen consequently you will not be able to use the program. the following image shows the problem:

  
 So to solve this problem run the CCP as administrator, then press F12, from the Browser Mode tab choose the internet explorer 10 compatibility view.

 Another pop-up window will show the following 2 options, choose Leave this page

 Then the CCP will run as normal by Allah's willing.

Cisco IP Communicator MAC Address Changes Frequently!!!


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

Cisco IP Communicator MAC Address Changes Frequently!!!

Cisco IP communicator will use the local network interface card MAC address as it's source MAC address to communicate in the local LAN. For example:





SEP stands for Selsius Ethernet Phone. Selsius was the name of the company Cisco acquired when they first began manufacturing VoIP technology, and the rest of the line is the MAC address.

In some cases you may encounter that the MAC address of the IP communicator changes frequently, causing the IP communicator to be unable to register. The issue is when you use the NIC card (physically plugged in) locally on the uc500 vs. the wireless NIC card (when you use the wireless to get internet)  vs. the VPN client (when you use either with a VPN client) you can get different MAC addresses assigned for each. 
To solve This problem use the "use this device name" and add a FAKE MAC address.  Then it will never change. Use the format SEP(MAC ADDRESS) (Example: SEP002215260FD4) under the ipcommunicator settings.

%SW_VLAN-4-IFS_FAILURE


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

%SW_VLAN-4-IFS_FAILURE

While preparing my lab in GNS3 using the 3725 L3 switch, i encountered the following error message:

" *Mar  1 00:18:57.371: %SW_VLAN-4-IFS_FAILURE: VLAN manager encountered file operation error: call = ifs_write_until / code = 0 (Unknown error 0)
    / bytes transfered = -1"





This message means that the VLAN manager received an unexpected error return from an IOS file system (IFS) call while reading the VLAN database. The first [chars] is the name of the function call, and the second [chars] is the filename. [dec] is the error code, the third [chars] is the textual interpretation of the error code, and the second [dec] is the number of bytes transferred. 
so the problems seems to be with the corrupted vlan.dat file. We need to delete the vlan.dat file and then reload the switch.
R2#delete vlan.dat
Delete filename [vlan.dat]?  y
