h3c switch

Ciscoportfast This is for the access port, a normal switching interface from down to up to pass: Down,listening,learning,fowarding Several states, total time is 30 seconds, This determines whether this port is blocking or fowarding and is also a mechanism for the switch to prevent loops. However, for direct access to such terminal equipment interface is not necessary to go through these steps, that is, from down directly into the state of fowarding. B

H3C configures the ACL control configuration for users who access the vswitch through SNMP. 1. The networking requirement only allows SNMP users from 10.110.100.52 and 10.110.100.46 to access the vswitch. 2. The Network Diagram controls the ACL of the SNMP user of the Switch. 3. Configure step # define the basic access control list and sub-rules.

Cisco switches: 1. show logging on the central switch and find the following logs:Apr 18 10:24:16. 265: % IP-4-DUPADDR: Duplicate address 172.30.30.62 on Vlan711, sourced by 0009.6b84.189e; indicates there is ARP virus,2. Run conf t and mac-address static mac address vlan id drop;3. The host with ARP virus is processed and then executed on the central switch.No mac-address static mac address vlan id drop, enabling the host to access network resources

Using Wvrp5.5 to complete a single arm routing experiment, this accidental factor, I try wvrp5.2a can do the success of a single arm experiment, the results of a try, incredibly impassability, and then to the next, all ports are zoned default VLAN 1, try again, found that still not, so, the single arm routing is unsuccessful, The situation is to be able to assign IP to the sub-interface, but it does not work. Okay, I'll send you the details of this experiment. Simulator or select the Mini-FAI s

The school network uses H3C authentication and requires the account to be bound to the MAC address to access the Internet. When the notebook is registered, it is bound with a wired network card, but now the price of wireless routing is the same as that of cabbage, so a wireless route is used as a switch. I bought this book to avoid the tedious network cable. Now I still need a network cable to access the In

About h3c Magic B1 wireless router settingsI need this: 1, to use the existing wireless ID BELLE-WMS 2, do not change the network segment, 10.5.60.0/23 3, to be able to log on to the AP management interface, the purpose is to add monitoring related to nagios and so on. If you use relay, you cannot manage the interface to monitor the device. In addition, the speed of wireless relay is estimated to be slow, because it is bound to the existing wireless B

I need to be like this: 1, to use the existing wireless ID BELLE-WMS2, do not change the network segment, 10.5.60.0/233, to be able to login to the AP management interface, the purpose is to add nagios and other related monitoringSo if you use the relay can not manage the interface monitoring device, the other with wireless relay speed estimation will be very slow, because it is first bound to the existing wireless BELLE-WMS repeater signal amplification, so consider the first, or LAN port confi

In the use of routers, we usually involve Telnet management. Here we will detail some H3C telnet settings. The following describes some command codes in H3C telnet settings to help you analyze these commands.

. In this case, dynamic routing does not have any practical advantages. On the contrary, dynamic routing may increase the management burden. The network only accesses the Internet through a single ISP. Because the ISP is the only Internet egress point, dynamic routing protocol is not required between the links. A large network configured with a centralized star topology. A centralized star topology consists of a central position (central point) and multiple branch locations (Scattered Points). E

Yesterday received H3C HR interview invitation, originally don't want to go, and their direction is not too consistent, looked at the interview notice, right next to my house, then try White. 9:00 to the interview, went to, a layer of standing a lot of people (also Essentials zero card), HR put us separate arrangements to do interview questions, I hate to do interview questions (Rogue, in other people's site to listen to others), there are two program

This article describes how to configure telnet for H3C and the specific steps and commands. The following article will give you a detailed introduction, I believe this article will help you. 1. Configure the IP address for H3C telnet login 2. Go to the user interface View 3. Set the authentication method to password authentication. 4. Set the password for login verification to the plaintext password "huawei

When using the H3C SR600 series routers, some netizens may find that as long as the routers start up, the memory usage increases sharply and exceeds 50%. This is a normal phenomenon or a problem with the routers. Today, I will explain why this problem occurs. The memory occupied by H3C SR600 series routers during startup mainly includes the memory occupied by features, the support module, and the memory occ

names to access servers in the local private network were generally used to create a dns server on the Intranet. The dns servers of Intranet users all point to the dns server on the Intranet, intranet DNS directly resolves the Intranet IP address of the Intranet server to the Intranet user after receiving the domain name resolution request for the Intranet server, so that the intranet user can directly access the Intranet IP address of the server, as mentioned above, access to the public IP add

The neighbor state machine after the mtu value of the H3C OSPF interface has been studying the OSPF principle and configuration of H3C over the past few days. Now there are two routers R3 and R4 connected through their respective Ethernet ports E0/0, after configuring the IP address and OSPF correctly, modify the mtu value of the R3 E0/0 interface to 1000 (1500 by default) and restart the OSPF process of R3

The permit and deny in the request are meaningless and only used to match the traffic.Rule permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255QuitTraffic classifier 1 // define class, match acl 3000If-match acl 3000:QuitTraffic behavior 1 // define as popular, and the action is to reject denyFilter denyQuitQos policy 1 // define QOS pol

The use of access control lists is specified by the range of numbers, 1000~1999 is an interface-based access control list, 2000~2999-scoped access control lists are basic access control lists, and 3000~3999-scoped access control lists are advanced access control lists. There are two matching sequences: Configuration order, auto sort: ACL number Acl-number [match-order {config | auto}] Several commands that the H3C ACL applies to an interface: I. Pac
