When the Cisco 3945 cascade device port setting trunk or division of the VLAN, may need to modify the cascade port work mode to trunk mode to realize the communication between.
If with the port cascade, can modify the 1 network interface for trunk mode,using the interface of the cascade:
Switch#configure terminal into the configuration sub model
Switch (config) #interface fastethernet0/1 into the F0/1 port
Switch (config-if) #switchport trunk encapsulation dot1q
Switch (config-if) #switchport mode trunk is set to TRUNK port
Switch (config-if) #switchport trunk allowed VLAN all to allow all VLAN from the mouth through the
Switch (config-if) #exit
Switch (config) #exit
If is the cascade and fiber interface, you can modify the 1 optical interfaces fortrunk mode, using the interface of the cascade:
Switch#configure terminal into the configuration sub model
Switch (config) #interface GigabitEthernet 0/1 into G0/1
Switch (config-if) #switchport trunk encapsulation dot1q
Switch (config-if) #switchport mode trunk is set to TRUNK port
Switch (config-if) #switchport trunk allowed VLAN all to allow all VLAN from the mouth through the
Switch (config-if) #exit
Switch (config) #exit
Please follow the thirteenth steps after the implementation of the description ofthe save current configuration.
WEB check the switch state:
If the implementation of view need to switch state, through
URL:http://192.168.1.5 or http://133.37.125.5
Account number: admin
Password: Cisco
After login to view.
Resume switch factory settings:
Switch>en enter privilege mode
Switch#write erase
Erasing the NVRAM filesystem will remove all configuration files! Continue?[confirm] enter
[OK]
Erase of nvram: complete
00:36:19:%SYS-7-NV_BLOCK_INIT: Initialized the geometry of NVRAM
Switch# reload
Proceed with reload? [confirm] enter
00:36:59:%SYS-5-RELOAD: Reload requested by console. Reload Reason:Reload Command.
A moment later, the switch will restart after a reboot, and restore to factory settings.
Remote login through the telnet switch terminal:
The machine IP is set to VLAN2 or VLAN3 and switch to the same segment;
Start - run -cmd;

7. Cisco 3560 2 switch mode configuration steps
A, configure the switch VLAN mode; there are two ways: first kind config#vlanID
The ID here is your individual needs to divide the VLAN number config-if#name name switch#show VLAN brief see VLAN to see if successful configuration second: VLAN configuration state switch switch#vlan database switch (VLAN) # VLAN ID name name VLAN configuration and distribution of the corresponding name.
Two, 3560 open the routing configuration
Switch (config) #ip routing switch (config) #ip route IPAddress net-hop to configure routing (static) switch (config) #ip default-gateway IPAddress configuration gateway
Three, open the link aggregation configuration of #conf t
SW (config) #interface range f1/1 -2
SW (config-if) #channel-group 1 mode desirable/on
SW (config-if) #swithport
SW (config-if) #switchport mode trunk
SW (config-if) #switchport trunk encap dot1q
Four, start the telnet management mode
Switch (config) #line vty 04 switch (config-line) #password switch (config-line)#login password
Five, open the Cisco log function
Switch (config) #logging on switch (config) #logging trap (config) #logging hostswitch your IP address switch (config) #logging facility you choose theinformation configuration of 3550 as the DHCP server
Six, the configuration of Cisco start DHCP function configuration address pool
Switch (config) IP DHCP pool name
Switch (config-pool) network mask
Switch (config-pool) dns-server
Switch (config-pool) default-router gateway set DHCP retention was notassigned address
Switch (config) IP DHCP excluded-address address
