the system, Enterprise branches and service channels can automatically switch to the backup center of the network system, in a short period of time to restore the operation of the enterprise information system, to avoid the enterprise business and external services to a standstill event. The level of disaster recovery is first introduced here, if you want to understand how each level of disaster recovery plan is developed,How to restore the system structure and other issues, you are welcome to

available and configured with the correct VLAN. For best results, you should use a tool that supports 10/100/gig connections. However, typically 10/100 connected tools work.
3rd Step: Request a DHCP address once the link is established, you can use the tool to request a DHCP address from the server. You should ensure that the assigned addresses match the corresponding subnets, verify the subnet mask, and confirm the default gateway and DNS server addresses. If the tool fails to obtain a respon

factors make now login dmoz very difficult, no one site can guarantee to be DMOZ included. Therefore, the only way to ensure a successful login is to be careful to fully comply with the DMOZ login terms.
When you have finished submitting your site to CDP, write down the date and the list of submissions. If you have an editor in the directory you submitted, it's best to write down the editor's name and email. This information is useful when you need

As a result, you need to shrink the data Backup window as much as possible, or even reduce it to 0. Technologies such as data snapshots (Snapshot), Continuous data protection (CDP, co

The Native VLAN is a trunk concept. The main purpose is not to discard unmarked frames. The receiving switch forwards all received unlabeled packets to the Native VLAN instead of discarding them. The default is VLAN1.
There can be multiple VLANs in the trunk of 801.Q. Each VLAN is prefixed with a header that describes the VLAN number, but a VLAN, without a header, is not encapsulated. is the native VLAN. The switch uses VLAN tags to mark the data when it is sent to which vlan,802.1q allows a unm
There are a lot of users using Cisco routers, global debugging of Cisco routers here today I would like to introduce you, I hope to be useful to you.
The boundaries of global and interface commands are obvious when conducting Cisco router configuration. In this case, we use the global to identify the commands that cannot be used for interface debugging or for specific transport media types and protocol debugging.
In the 2500 series Cisco routers, you can use the Debug command to analyze the Ci
confirm that the problem is not caused by an individual computer, you can then connect your Portable Network tools to the Office line, check to see if a link is established, and then check the port configuration to ensure that the port is available and configured on the correct virtual LAN.
Third, the application
After "confirm" and establish a link, use the tool to request a DHCP address from the server. You should ensure that the assigned addresses match the corresponding subnets, verify th
Access to both the Remote Desktop server and the RemoteApp Publisher can use a certificate to encrypt the session for security purposes
When a certificate is used, the client queries the certificate revocation list CRL each time it connects to the Remote Desktop server, in order to avoid an error, to extend the CRL into the certificate before requesting the certificate
1. Extend the CRL into a certificate
In BJDC Server Manager, expand AD Certificate Services management, and open the proper
certificate monitoring tools in Windows Server 2008, Pkiview.msc and complex certutil.exe tools.
Pkiview.msc
When using the Pkiview.msc tool, users need to open MMC for the PKI. This command will start the PKI Health tool to ensure that all activities and conditions related to the existing pke are monitored. PKIView also monitors authority information Access (AIA) and CRL distribution (CDP) extensions to ensure that the monitoring services are not
port receives.
The access port is characterized by allowing only traffic that conforms to pvid.
TRUNK:
Trunk Relay links allow various VLANs to pass. When you receive a tag without tags, you mark it with your own pvid, and when you send a frame if Vid=pvid removes pvid, unlike access, Trunk has one of its own intrinsic VLANs ( The Native VLAN, also known as Pvid, is used to send data or manage traffic between switches such as CDP,BPDU, and frames
using less time
Do not run all your backups at the same time.
Do not run a batch program at the same time as a large backup.
Use the backup option to write to multiple files. This will scatter your I/O and increase the number of threads.
Use several backup technologies at the same time: complete, differentiated, and log.
Local recovery
From a recovery standpoint, most of the time mentioned above is used for recovery. Here are some additional tips:
Different phases are used in different a
Global debugging
When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Discovery Protocol (Cisco Discovery PROTOCOL,CDP). We telnet remotely to the router by remote
tag, then the message is tagged with tag;The access port is responsible for receiving the terminal equipment, when it receives a frame, if the frame is not marked, it uses its own pvid to mark him, it emits a frame if the vid=pvid to remove the mark to ensure that the frame transmitted to the terminal device has not been changed, Pvid is a property on each port when the VLAN is partitioned, and by default the initial pvid of each port in the Cisco switch is 1, indicating that he is a member of
