Network Device-Huawei-switch stack termination Configuration

Network Device-Huawei-switch stack termination Configuration

First, let's talk about the demand. In fact, in the case of medium and large IDC operators currently in contact with enterprise networking, many customers have high requirements on the early positioning and demand of redundancy solutions. Many of our competitors have outdated (mstp + vrrp) technical solutions and the most advanced virtualization solutions ..

So here I will also briefly talk about some typical examples of the common cases I have encountered in the past:

In this case, let's just tap into the logic topology structure:

PS: The structure diagram is partially harmonious and only part of it is captured.

For a state-owned enterprise's bidding scheme (which has won the bid), the network architecture is fully implemented by me. Now I think it is a bit excited.

I can only disclose some device parameters:

Firewall checkpoint

Switch H3C-10000 + series

I will not repeat the initial design ideas and introductions here. Everyone understands each other.

The figure below is the original draft, so it is a bit rough. The final version is not easy to disclose and professional qualities. It cannot be pasted out.

Keywords: redundancy, traffic switching, spof

Well, I will not talk about it here.

First, we will introduce the practical configuration experience and notes of the most common Huawei enterprise-level S5700 stack. Serving food!

Let's talk about the prerequisites for supporting the stacked Huawei S5700 series:

S5700SI, S5700EI

System firmware: V100R005, V100R006, and V200R001

S5710EI, S5700LI

System firmware V200R001

Separately equipped, stacked interface board + dedicated stacked cable (this is a lot of money), State-owned enterprises also said.

Huawei stack is enabled by default, just like STP.

Silly configuration Stack: The stacked interface board and stacked cable are fully connected before power-on. Automatically stacked by default when powered on

Job Configuration:

Stack slot-id renumber new-slot-id (after the stack ID is configured, the switch must be restarted to take effect. Before executing this command, you must first execute the stack enable command to enable the stack function of the device)

Stack slot-id priority (msater with lower priority)

Stack timer mac-address switch-delay-time (mac switching time)

Display stack

Display stack peers (view status)

After the stacked line is inserted (according to the intersection rule of one port and two ports of chrysanthemum), it is started and stacked. Configuration complete

Then you will see the following situation: (how to configure a fool)

The interface is changed to 24X2 with a total of 48 ports.

So here I want to emphasize. I also had a simple chat with my colleagues who started to work on the Internet. What is stack vulgar understanding?

Stack refers to the combination of multiple stand-alone devices that support the stacking feature, and the logic is combined into a whole device. Stack devices use stacked cables for Ring-or link-based topology networking. up to nine single-host devices can be connected at the same time, and nine devices can logically forward packets to one device.

Easy to understand: the two servers become one, and all operations can be performed on one server. For example, you can enter a management address. You do not need to configure one server like cascade. Simple and crude.

We strongly recommend that you use this technology to install X outside, because you do not have one. You will not have the chance to touch this device. People are in the rivers and lakes and cherish the opportunity to touch devices !!

I have also made some operations here. In the case of power-on, I have added operation records of stacked interface boards. That is: the original single point, later because of the security for the redundant write upgrade solution, the results asked the boss to implement the budget.

When a device is running on a stack board, the switch outputs the above information. The system prompts that the Board has been properly loaded into the switch.

It does not affect the normal operation of the switch and does not cause restart (for example, after insertion, it will cause restart and so on)

Scenario 1: However, if you are adding a new device, you need to stack it. If you were running on a single machine, you need to restart the two switches. Otherwise, the function cannot start.

Case 2: If you are stacking, replace the member group devices and connect the Board bayonet. Automatic Identification of extended devices (remember, in this case, it must be configured by a professional network engineer in advance. Otherwise, when the priority of new devices is the same, the mac address may be larger than the original device, this will cause the configuration file of the new device to overwrite the old device, and cause the configuration file to be lost)

PS: to do anything, you must first consider how to quickly restore and save global configurations. Good habits must be well maintained.

Now, the configuration is here. The following is a common configuration item:

First, modify the priority to determine that the current running switch is the Master.
