steps to configure cisco switch

Description The Zabbix monitoring server is already configured to monitor the switch using Zabbix. Specific actions: The following operations are performed on the monitored switches, for example, Cisco switches. First, log on to the Cisco switch and turn on the SNMP service

You can configure a serial interface through a virtual terminal. to configure a serial interface, follow these steps: 1. In Global mode, enter the command "interface serial 0" to enter the serial interface configuration mode. 2. Each connected serial interface must have an IP address and subnet mask to forward IP packets, in interface configuration mode, enter th

Configure linux as log service host of PIX, cisco, and huawei-Linux Enterprise Application-Linux server application information. The following is a detailed description. Log host settings Vi/etc/sysconfig/syslog Set SYSLOGD_OPTIONS = "-m 0" Change SYSLOGD_OPTIONS = "-r-m 0" //-r writes from the remote host-m 0 sables 'mark' messages Vi/etc/syslog. conf Add the following content Record all logs with

The configuration mode of the switch can be broadly divided into two categories: one is the configuration mode represented by the Cisco switch, and the other is the configuration mode represented by Huawei and the H3C switch. In fact, the two configuration modes are not fundamentally different, but the configuration of

port belongs to a link only), and the number of each STP consists of table 6-2.Table 6-2. STP components in a Switch and 146 Segment Network STP Component number Root bridge 1 root port 14 Specify port 146 Also, all options are based on the following four-step comparison principle: Minimum root bridge bid Minimum root path o

This article uses a specific example to illustrate how to configure the access to ADSL through the vro. What problems should we pay attention to during access? The following articles will benefit you a lot. Note: In this case, a common adsl modem and a cisco 25001841) router (dual Ethernet port) and IOS 12.2 (15) T need to be used to connect to the China Telecom adsl PPPoE, able to achieve LAN Internet shar

In Cisco 3550, dhcp configuration is often discussed on the network, but there are mostly errors and omissions. According to the configuration described on the internet, after "ip helper-address dhcp server ADDRESS, in the project, I found that the client could not obtain the IP address from the DHCP server. I recently configured 3550 as the DHCP server relay proxy, and I was confused for a long time, later, I searched for information on the Internet

internal legal address, and specifies the legal address to which the conversion is required. If there are E-mail servers or FTP servers in the internal network that can provide services to external users, the IP addresses of these servers must adopt static address translation so that external users can use these services. To configure static address translation, follow these steps: 　　 (1) Establish static

This article describes in detail how to configure an ACL from the basic concepts, usage principles, and access time. If someone says that a route switch device is mainly used for routing and switching, it must be a layman only when it is used for routing and switching data packets. We can use a common HUB only to exchange data packets. If we only use the routing function, we can select a WINDOWS Server for

Router (config) # frame-relay switching simulate a Router as a frame relay switch Router (config) # inter s1/1 Router (config-if) # clock rate 128000 Router (config-if) # encapsulation frame-relay configuration interface encapsulates frame relay The default Frame Relay encapsulation enabled on the interface is Cisco encapsulation. To connect to a non-Cisco router

administrator, when we access a new service on a vswitch, we always need to find an idle port on the Cisco switch and configure necessary services, connect the network cable, but when there are many cables on the switch, with the naked eye, it is difficult to accurately identify idle ports at once (if an error is acci

This experiment is to configure a general router as a frame relay switch to provide a frame relay experimental environment for other experiments in this chapter.1. Tutorial PurposeThrough this experiment, you can master the following skills:● Configure a frame relay environment with only two nodes;● Configure a star fr

various vswitches are different, administrators often encounter configuration Errors When configuring vswitches. For example, the network is disconnected due to incorrect VLAN division, the ports are mistakenly disabled, and the switch and nic pattern configuration do not match. It is sometimes difficult to find such faults and requires some experience. If you cannot ensure that your configuration is correct, first restore the default factory configu

Define the server. On other Cisco devices, the default RADIUS port is 1645/1646 (authentication/accounting ). On the Catalyst, the default port is 1812/1813. If you use CiscoSecure or a server that is in contact with another Cisco device, port 1645/1646 is used. Run the following command to define the server: set radius server #. # auth-port 1645 acct-port 1646 primary Define the server key. Because it cau

solved! How to judge the network loop Because almost all newly purchased switches support the port loop monitoring function, we can use this function to automatically determine whether a network loop occurs on the specified communication port. Once the loop monitoring function is enabled on the specified Ethernet communication port, the switch device can automatically and periodically scan and monitor all communication ports to determine whether the

Huawei switch port monitoring and image configuration steps. The features of Huawei switch port monitoring have previously been introduced to you. Today, we have taken them out again to better understand the port monitoring configuration steps, and the internal connection between the port listening command of the Huawe

VLANs. VLAN can reduce unnecessary data traffic to the minimum by establishing network firewall, isolate the transmission between each VLAN and the possible problems, increase the network throughput greatly, and decrease the network latency. In a virtual network environment, you can control the communication between users in the same physical network segment by dividing different virtual networks. This effectively implemented the data confidentiality, and configuration is not cumbersome, networ
