juniper switch configuration

As a network operations engineer, if the management of the routing, switching equipment more, then you will also encounter the same problem with me: The device configuration is often adjusted, especially the access layer switch, in case you forget to save the configuration, and the next day a switch power-down restart,

You can configure a vswitch in two ways: local configuration and remote network configuration, however, note that the latter configuration method is only available after the previous configuration is successful.1. Local Configuration For local

loop monitoring function of the Ethernet 16 port, in the system view of the switch, enter the string command "interfaceGigabitEthernet1/0/16" and click the Enter key. After the switch is configured, the view status of port 16 on the Ethernet is displayed, at the same time, the command line prompt of the switch will automatically become "H3C-GigabitEthernet1/0/16

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict some ports. I. Network Description User‑pc1 i

The configuration of the switch has always been very mysterious, not only for the general user, but also for the vast majority of network administrators, but also as an important and basic indicator of the level of network management. This is mainly for two reasons, one is the majority of enterprises configured switches are desktop non-network management switch,

Reasonable configuration solves the problem of Switch network loop, in the way of judging switch network loop, this paper makes a preliminary analysis of switch network loop problem from log information and enabled state, then rationally configures the switch and finally sol

by creating different user-groups. A port can belong to multiple user-groups. ports that do not belong to the same user-group cannot communicate with each other, up to 50 user-groups are supported. [H3C] user-group 20: create user-group 20. By default, only user-group 1 exists. [H3C-UserGroup20] port Ethernet 0/4 to Ethernet 0/7 add port 4 to port 7 to VLAN20, initially in user-group 1 [H3C] display user-group 20 displays information about user-group 20 6. Cluster

already exist and cannot be the default Vlan;hybrid port join VLAN must already exist, the VLAN joined by the trunk port cannot be the default VLAN.With this configuration, the current Ethernet port can forward messages for the specified VLAN. The hybrid port and trunk ports can be added to multiple VLANs, enabling interoperability of the VLAN on the switch with the same VLAN on the peer

To effectively manage the switch configuration file, you must run the copy command in a timely manner and in an appropriate location. By using the copy command, IOS software can move the configuration file from one component or device to another required component and device. This command mainly has two parameters. The first parameter indicates the source locatio
