deployed with protected ports cannot communicate with each other.
If you configure pvlan on a layer-3 switch and the layer-3 switch is still a DHCP server, you need to configure a multi-layer switch hybrid port (that is, int VLAN *).
When configuring a DHCP server on a multi-layer switch, you must configure the VLAN interface address of the VLAN where the host is located, because DHCP uses UDP, dhcp on the vswitch finds the DHCP network segment corresponding to the VLAN Interface and assi
is performed on the specified port of the DP (designated port), and the port will not change. It will only be DP, which can prevent the newly added switch from becoming root, the port becomes a permanent DP. If the newly added vswitch wants to become root, its port cannot work until the new vswitch requests complete Rp. Show spanning-tree inconsistentport

Review information security governance (4)J0ker introduces the definitions and differences of various security documents in information security management (CBK. We all know that after the establishment of various security rules and regulations, every Member of the Organization must understand and consciously abide by the rules to play its due role. To achieve this goal, this document describes the Security Awareness Tool.

2.6 Summary (Summary)
You should have a basic understanding of what git is and the difference between git and other cvcs you might use. You should also have a working git version of your personal identity in your system. It's time to learn some of Git's basics.
Git actually uses records

The code is
~s and S~e, where 0~s represents the element that has been selected, and S~e represents the element that has not been selected.
Perm (set, S, e)
{
order from s~e to select an element in exchange with S (that is, select an element)
call Perm (set, S + 1, e)
until S>e, that is, the remaining set is empty, output set

The C language code is as follows:

[, reporthook [, data]):The urlretrieve method directly downloads remote data to the local device. The filename parameter specifies the path to be saved locally (if this parameter is not specified, urllib generates a temporary file to store data). The reporthook parameter is a callback function, this callback is triggered when the server is connected and the corresponding data block is transferred. We can use this callback function to display the current download progress. The following example
In the previous article "review access control" in the cissp development path series specially planned by 51cto Security channel, j0ker introduced the basic concepts of access control and the basic principles of three access control types (physical, logical, and management. We know that information security and every security-related technology aim to protect the confidentiality, integrity, and availability of information assets (CIA) from any or all damages, as well as access control. Therefore

2. It is recommended to cache objects, especially DOM access, which consumes resources:
// C. length is not cached. In each iteration, the length of the Array function foo () {var I, B, c = [,]; for (I =; I
3. We recommend that you do not perform a deep nested judgment in the function:
// Too many nested judgment statements in the function foo1 () {var r ={}; r. data ={}; r. data. myProp = 2; if (r) {if (r. data) {if (r. data. myProp) {// logical processi

Third, preparation experience1.osg7 wrote very well, it divided 21 chapters, so in learning easy to grasp the progress, not like the AIO and CBK chapter is very large, feel too much, and write more fluent than AIO, easier to understand. Again with Chinese translation, see OSG is enough, occasionally refer to Cbk,aio basic don't look.2. To give yourself enough time to study,
detailed financial reports of enterprises in the first half of this year, however, at the same time, access from other departments should be rejected. The centralized or distributed access control method previously introduced is not suitable for this scenario. At this time, we need to use the following data access control methods.
In the CBK of cissp, five data access control methods are most commonly used: independent access control (DAC) and Mandat
foo () {
var i, B, c=[,,];
for (i=;i
2, it is recommended to cache objects, especially DOM access is more resource-consuming:
C.length does not have a cache, each iteration computes the length of the array
function foo () {
var i, B, c=[,,];
for (i=;i
3. It is not recommended to make deep nesting judgments within functions:
function nested judgment statement too many
