Cisco Catalyst 2960 switch configuration commands

(1) the enable password (enable password), the password in plaintext display

Enable password (enbale secret), the password to cipher text display

Model Switch.> / user prompt straight

The Switch.>enable / * enter privilege mode

Switch.# / privileged mode (input ciphertext before entry)

Switch.#config terminal / * enter global configuration mode

Switch. (config) # / configuration mode prompt

Switch. (config hostname Pconline) # / * set the host name Pconline

Pconline (config) enable password cisco3560 # / * set the enable password for pconline

Pconline (config) enable secret cisco3560 # / set enable password for network

Pconline (config) line vty 015 # / set the virtual terminal lines

Pconline (config-line) login / # landing verification

Pconline (config-line password cisco3560) # / set the virtual terminal password

Two, VLAN switch setting

Model Switch.> / user prompt straight

The Switch.>enable / * enter privilege mode

Switch#vlan database into the VLAN settings;

Switch (VLAN) # VLAN 2; VLAN 2

Switch (VLAN) #no VLAN 2 + VLAN 2;

Switch (config) #int f0/1; into the network port 1

Switch (config) #int giga0/1; into the sink Gigabit port 1

Switch (config-if) duplex {auto full half} # | | set port --- automatic / full duplex or half duplex

Switch (config-if) #switchport mode trunk; the port is set to sink mouth

Switch (config-if) #switchport mode access; the port settings for the access mode

Switch (config-if) #switchport trunk allowed VLAN 1, 2; group VLAN set 1,2 export permit

Switch (config-if) #switchport trunk VLAN 2; 1 is set in VLAN allowed

Switch (config-if) #switchport access VLAN 2; the current port into VLAN 2

Switch (config-if) #switchport trunk encap dot1q; set the VLAN relay

In Cisco network, there are four main types of switches in the LAN interface in the final steady state:

Access/ trunk/ multi/ dot1q-tunnel.

1, access: is mainly used to access terminal equipment, such as PC, server, print server.

2, trunk: is mainly used in connection with other switches, to support multiple VLAN in line.

Multiple VLAN bearing 3, multi: in a line, but unlike trunk, it does not carry data tagging. Mainly used for access to support multiple VLAN servers or network analysis apparatus. Now don'tuse this kind of interface, in the Cisco network equipment, also does not support this type ofinterface.

4, dot1q-tunnel: is used in the Q-in-Q tunnel configuration.

Switch (config) #vtp domain; set the VTP domain name

Switch (config) #vtp password; set the VTP password

Switch (config) #vtp mode server set up the VTP model;

Switch (config) #vtp mode client set up the VTP model;

Three. Set the IP address switch

Switch (config) #interface VLAN 1 to VLAN 1

Switch (config-if) #ip address 132.37.48.3 255.255.255.0; set the switch management IP

Switch (config) #ip default-gateway 132.37.48.1; set the switch the default gateway

Switch (config) #end; exit current mode

Switch#conf t enter privilege mode

Switch (config interface fa0/5) #

Switch (config-if) # shutdown closed port

Switch (config-if no shutdown) # open ports

The four switch show commands.

Privileged mode:

Save the configuration information of switch#write;

Switch#show VTP; see the VTP configuration information

Switch#show run; see the current configuration information

Switch#show VTP; see VTP switch information

Switch#show VLAN; see the VLAN configuration information

Switch#show interface view port information;

Switch#show interfaces FastEthernet 0/1 switchport; two layer display port state, can be used to determine whether the port is two or three layers of export.

Switch#show int f0/0; look at the specified port information

Sw1924_b#show IP; see the setting

Sw1924_b#show versi; check the switch version information

Sw1924_b#show running-config; check the switch current running configuration information

Sw1924_b#show int e0/1; first port information view switch

MAC address binding ports based on

Switch#config terminal enter configuration mode

Switch (config Interface FastEthernet) # 0/1 into the specific interface configuration mode

Switch (config-if) #Switchport port-secruity configure port security mode

Switch (config-if) switchport port-security mac-address MAC (address MAC)

To configure the port to bind the host MAC address

Switch (config-if) no switchport port-security mac-address MAC (address MAC)

Delete the MAC address of the host.
