Basic Cisco Switch Configuration ( 3560 multilayer )

Sebelumnya, kita sudah bahas mengenai router cisco, sekarang kita beralih ke peralatan yang baru, yang namanya switch. Untuk perintah dasar dari switch Cisco, hampir semuanya sama seperti perintah dasar pada router Cisco. Lihat posting sebelumnya, tentang konfigurasi dasar router Cisco. Jika sudah bisa dan lancar pada Cisco router, tentunya anda tidak akan kesulitan dengan switch Cisco.

Berikut list command basic yang saya copy pastekan dari situs tetangga.

Command	Descriptions
switch>?	The ? works here the same as in a router Used to get the list of all available commands
switch>enable	User mode, same as a router
switch#	Privileged mode
switch#disable	Leaves privileged mode
switch>exit	Leaves user mode
switch#show version	Displays information about software and hardware.
switch#show flash:	Displays information about flash memory (will work only for the 2900/2950 series).
switch#show mac-address-table	Displays the current MAC address forwarding table .
switch#show running-config	Displays the current configuration in DRAM.
switch#show startup-config	Displays the current configuration in NVRAM.
switch#show vlan	Displays the current VLAN configuration.
switch#show interfaces	Displays the interface configuration and status of line: up/up, up/down, admin down.
switch#show interface vlan1	Displays setting of virtual interface VLAN 1, the default VLAN on the switch.
To Reset Switch Configuration
Switch#delete flash:vlan.dat	Removes the VLAN database from flash memory.
Delete filename [vlan.dat]?	Press Enter
Delete flash:vlan.dat? [confirm]	Press Enter
Switch#erase startup-config	Erases the file from NVRAM.
Switch#reload	Restarts the switch.
To Set Host Names

Switch(config-line)#login	Enables password checking

Switch(config-line)#exit	Exits line vty mode
Switch(config)#
To Set IP Addresses and Default Gateways
Switch(config)#interface vlan1	Enters the virtual interface for VLAN 1, the default VLAN on the switch
Switch(config-if)#ip address 192.168.0.10 255.255.255.0	Sets the IP address and netmask to allow for remote access to the switch
Switch(config-if)#exit
Switch(config)#ip default-gateway 192.168.0.5	Allows IP information an exit past the local network
To Set Interface Descriptions
Switch(config)#interface fastethernet 0/1	Enters interface configuration mode
Switch(config-if)#description Finance VLAN	Adds a description of the interface
To Set Duplex Operation
Switch(config)#interface fastethernet 0/1	Moves to interface configuration mode
Switch(config-if)#duplex full	Forces full-duplex operation
Switch(config-if)#duplex auto	Enables auto-duplex config
Switch(config-if)#duplex half	Forces half-duplex operation
To Set Operation Speed
Switch(config)#interface fastethernet 0/1
Switch(config-if)#speed 10	Forces 10-Mbps operation
Switch(config-if)#speed 100	Forces 100-Mbps operation
Switch(config-if)#speed auto	Enables autospeed configuration
MAC Address Table
switch#show mac address-table	Displays current MAC address forwarding table
switch#clear mac address-table	Deletes all entries from current MAC address forwarding table
switch#clear mac address-table dynamic	Deletes only dynamic entries from table

Di bawah ini contoh konfigurasi dasar switch yang saya buat.

Switch>en

Switch#config ter

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#host SW-CORE

SW-CORE(config)#enable secret ensecret

SW-CORE(config)#username user01 password user01pass

SW-CORE(config)#inter vlan 1

SW-CORE(config-if)#ip address 10.1.1.1 255.255.255.0

SW-CORE(config-if)#no shut

SW-CORE(config-if)#exit

SW-CORE(config)#aaa new-model

SW-CORE(config)#aaa authentication login default local

SW-CORE(config)#inter range fa0/1-24

SW-CORE(config-if-range)#shut

SW-CORE(config-if-range)#inter range gi0/1-2

SW-CORE(config-if-range)#shut

SW-CORE(config-if-range)#inter fa0/1

SW-CORE(config-if)#description PC0 to manage switch

SW-CORE(config-if)#switchport access vlan 1

SW-CORE(config-if)#duplex auto

SW-CORE(config-if)#speed auto

SW-CORE(config-if)#no shut

SW-CORE(config)#banner motd c

Enter TEXT message.  End with the character 'c'.

Warning...!!!

Segala aktifitas perubahan pada router ini,

SW-CORE(config)#

Dari komputer client/user, coba ping dan telnet ke arah switch. Hasilnya seperti gambar di bawah ini.

Sampai disini, selanjutnya akan saya bahas mengenai vlan pada posting selanjutnya…
