Hello everyone, Lin Fei to answer the above questions, Cisco switch configuration commands experimental report, Cisco switch configuration commands many people do not know, now let's take a look!

Basic Cisco layer 3 switch configuration command

1. Commands supported by the switch:

The basic state of the switch:

Switch:ROM status, router is rommon

Hostname; user status

Hostname #; privileged mode

Hostname (configuration) #; global configuration mode

Hostname (configuration-if) #; interface status

Toggle password settings:

Switchenable enters privileged mode.

Switch # configure terminal; enter global configuration mode.

Switch (configuration) # hostname sets the hostname of the switch.

Switch (configuration) # enable password xxx set privileged encryption password

Switch (configuration) # enable password xxa set privileged non-secret password

Switch (configuration) # Line console 0; enter the console port.

Switch (configuration line) # line vty 0 4; enter the virtual terminal

Switch (configuration line) # login; allow login

Switch (configuration line) # password xx; set login password xx

Switch # exit; release instruction

Toggle VLAN settings:

Switch # vlan database; enter VLAN settings.

Switch (VLAN) # VLAN 2; build VLAN 2

Switch (VLAN) # does not have VLAN 2; delete vlan 2

Switch (config) # int F0ram 1; enter port 1

Switch (configuration-if) # switch port accesses VLAN 2; current port joins vlan 2

Switch (config-if) # switchport mode trunk; set to trunk

Switch (configuration-if) # vlan 1, 2 allowed for switch port trunking; set allowed vlan

Switch (configuration-if) # switch Port Relay Encapsulation dot1q Settings vlan Trunk

Switch (configuration) # vtp domain; set VTP domain name

Switch (configure) # vtp password; set vtp password

Switch (configuration) # vtp mode server; set vtp mode

Switch (configuration) # vtp mode client; set vtp mode

Set the IP address of the switch:

Switch (configuration) # interface VLAN 1; enter vlan 1

Switch (configuration-if) # ip address; set IP address

Switch (configuration) # ip default gateway; set default gateway

Switch # dir flash: view flash memory

Toggle display commands:

Switch # write to save configuration information

Switch # show vtp View vtp configuration Information

Switch # show run to view current configuration information

Switch # displays vlan to view vlan configuration information

Switch # display interface; view port information

Switch # show int F0amp 0; view the specified port information.

Add:

The routing ability of layer 3 switch is stronger, which is reflected in the interworking function of vlan and the routing ability of port. The following is an introduction:

Enable routing function: ip routing

The gateway entering the vlan configuration network segment is the same as the routing configuration interface

Interface vlan 1

Ip 192.168.1.1

The routing configuration is the same as the router configuration, except that the interface is changed to a VLAN VLAN number, and the interface routing function is enabled to enter the interface configuration: no switched port.
