These are the basic configuration commands for Catalyst 1900 Series Switch and Catalyst 2800 Series. The commends in the examples are for 1900 switch, but also serves to configure the switch 2800.
Cisco Catalyst 1900 Series Switch
Cisco Catalyst 1912 Switch
Cisco Catalyst 1924 Switch
Cisco Catalyst 2800 Series Switch
Cisco Catalyst 2802 Switch
Cisco Catalyst 2808 Switch
Cisco Catalyst 2822 Switch
Cisco Catalyst 2828 Switch
These models in particular, they are old enough, use “Firmware” as the operating system and some commands for the configuration is different to other series.
SWITCH TO APPOINT
Switch> enable
Switch # configure terminal
Switch (config) # hostname 1900 (appointed to the switch)
1900 (config) #
Set Password “ENABLE SECRET” and “ENABLE PASSWORD”
1900> enable
1900 # configure terminal
1900 (config) # enable secret password * (Enable Secret password set)
1900 (config) # enable password password ** 1-15 level (set password Enable Password)
1900 (config) #
* Enable Secret is recommended to set it generates a global key figure in the switch.
** Tier 1 is a user-mode password with different privileges. Level 15 is the enable mode password. These passwords are unencrypted.
GATEWAY IP ADDRESS AND SET OF SWITCH
1900> enable
1900 # configure terminal
1900 (config) # ip address XXXX XXXX (the IP of the switch set)
1900 (config) # ip default-gateway XXXX (configures the gateway switch)
1900 (config) #
SUB-MODE INTERFACES ETHERNET / FAST ETHERNET
1900> enable
1900 # configure terminal
1900 (config) # interface ethernet 0 / 1-0 / 24 (entering the way of the interface)
1900 (config-if) #
1900> enable
1900 # configure terminal
1900 (config) # interface fastethernet 0 / 26 or 0 / 27 (enter the interface mode)
1900 (config-if) #
VTP MODE SET
1900> Enable
1900 # configure terminal
1900 (config) # vtp server / client / transparent (designated VTP mode)
1900 (config) # vtp domain names (domain name designates VTP)
1900 (config) #
CREATE VLAN’S
1900> enable
1900 # configure terminal
1900 (config) # name name vlan X (X creates the vlan number and names)
1900 (config) #
HOW TO SET UP A TRUNK INTERFACE
1900> enable
1900 # configure terminal
1900 (config) # interface fastethernet 0 / 26 or 0 / 27 (enter the interface mode)
1900 (config-if) # * trunk on (enabled as a trunk interface)
1900 (config-if) #
* The Catalyst 1900 only supports trunking interfaces F0/26 and F0/27. The command “trunk” can be on / off / desirable / auto.
Duplexing SETTING IN AN INTERFACE
1900> enable
1900 # configure terminal
1900 (config) # interface ethernet / fastethernet 0 / X (enter the interface mode)
1900 (config-IF) # duplex auto / full / half / full-flow-control (duplex mode changing the interface)
1900 (config-if) #
DELETE SWITCH SETTINGS
1900> enable
1900 # delete nvram * (deletes the switch configuration)
1900 # delete vtp * (remove the vlan’s configured)
# 1900
* To make the switch to zero is necessary to clear both.
SOME COMMANDS Show
1900 # show ip (shows the IP address of switch)
1900 # show interface ethernet 0 / 1-0 / 24 (shows statistics for the selected ethernet interface)
1900 # show interface fastethernet 0 / 26-0 / 27 (sample statistics interface fastethernet selected)
1900 # show vlan X (vlan displays information about selected)
1900 # show vlan-membership (shows all ports and vlan assignments)
1900 # show trunk a or b (shows the configuration of the trunk, the “a” is the F0/26 and “b” the F0/27)
1900 # show trunk a or b allowed-VLANs (VLANs that share shows that trunk)
1900 # show vtp (shows the configuration vtp)
