802.1q trunk between Cisco and Nortel switches

We do have a running config between cisco catalyst 6509 and BayStack 450.

On the Cisco: configure a port for trunk with encapsulation "dot1q". Assign the native VLAN to 1 (default). Set the negotiation to off (it MUST connect).

On the BayStack: Set a port to "tagged access". You don't have to define VLANs, but put all VLAN that need to be transportet do the trunking port. Assign the PVID of that port to 1 (same as Cisco default).

ATTENTION: DONT USE CHANNELING or MULTILINK-TRUNKS. That doesn't work. This might work, but it will most certainly not. Even if it does seem to work in the first, it will produce strange errors on the network. Also if you have configured a MLT previously and reverted the config: use another port. The config seems to be persistant.

VPN Router ( Contivity) 1100/1010 reset password e boot error

para fazermos reset a password do Contivity temos de entrar em modo recovery e sabendo o IP, fazer restore to factory defaults

Caso nao seja possível ter o IP, ligamos o nosso PC ao contivity e activamos o WIRESHARK que nos devolve um maravilhoso gratious arp com o IP de management contivity.

Caso aconteça apagarmos ficheiros do contivity nas areas /ide1/system/bin ou ide1/system/manage, podemos recuperar atraves de cmd e do FTp do Contivity.

Copiamos a pasta de manage e depois em recovery mode, restauramos um backup para cima do contivity.

Upgrade for Windows 7 from earlier XP or Vista

Boas,

Eu preferencialmente prefiro clean install.

Já experimentei o upgrade e o clean install e o upgrade como é óbvio nao permite ver grandes melhorias.

instalei no meu Tecra M1 um clean de windows 7 PRo e noto muito melhor performance do que no windows vista Business.


Segue informaçao sobre upgrade do windows existente para o novo windows 7:

1. Windows XP para Windows 7 :

a melhor forma é guardar os documentos ( atraves de user profile transfer e fazer clean install do windows 7

"Information here is still a bit murky because Microsoft has not specified which XP editions will be eligible.

The good news is that the company has confirmed that users currently running Windows XP will be able to buy the cheaper upgrade option of Windows 7. However, they will only be able to perform a clean install.

The hassle of backing up applications and user data will fall on the user; the upgrade process will not backup anything.

That may come as a shock to some, but Microsoft typically lets users purchase the cheaper upgrade option by owners of the last two releases of Windows (in this case XP and Vista) but the older of the two operating systems usually require a clean install.


From Windows Vista to Windows 7


Microsoft will only allow the following upgrade paths to Vista users.

For example, users who purchase an upgrade copy of Windows 7 Professional and have Vista Home Premium will only be able to perform a clean install.

Here's the migration list:

Windows Vista Home Premium to Windows 7 Home Premium
Windows Vista Business to Windows 7 Professional
Windows Vista Ultimate to Windows 7 Ultimate

If you are performing an upgrade installation from Windows Vista, the base language must match the target Windows 7 language, you must have about 9GB of free space for the installation, and the installation can only occur on the same partition that holds Windows Vista. Existing applications and user data will be automatically migrated to the new Windows 7 installation.


Clean installs will require about 16GB for the installation process. Unless the user chooses to repartition or format the current partition, Vista's files from C:\WINDOWS will be preserved under C:\WINDOWS.OLD, just as when upgrading from XP to Vista. Clean installs will also have to be performed when upgrading from a 32-bit version to a 64-bit version.


Windows Anytime Upgrade (WAU)

Once you have some edition of Windows 7 on your system, whether you purchased it via an OEM or just upgraded from Windows XP or Windows Vista, you will be able to upgrade to a "more premium" version of Windows 7 by purchasing an upgrade key to unlock additional features, just as in with Vista.

For example, you could start off with Windows Vista Home Premium, upgrade to Windows 7 Home Premium, and then later choose to upgrade to Windows 7 Professional.

As with Vista, the same DVD includes the various editions. Unlike with Vista, every edition of Windows 7 is a superset of the previous edition, so you will not lose any features when upgrading.
