Divide VLANs and configure trunk to implement intercommunication between different switches

. Configure the pc ip Address

Ii. vlan2 and vlan3

S1 (config) # VLAN 2 \ divide vlan2

S1 (config-VLAN) # namecw \ rename vlan2

S1 # VLAN database \ Access VLAN

S1 (VLAN) # VLAN 3 namejs \ method 2 vlan3

VLAN 3 added:

Name: JS

3. Add pC1 PC2 to vlan2 PC3 pc4 to vlan3

S1 (config) # interfacefastethernet 0/1 \ enter interface mode

S1 (config-If) # switchportaccess VLAN 2 \ add this port to vlan2

S1 (config-If) # exit

S1 (config) # interfacerange fastethernet 0/3-4 \ enter interface mode

S1 (config-if-range) # switchportaccess VLAN 3 \ add this group of interfaces to vlan3

VLANs do not communicate with each other

Configure the vswitch topology of S2 according to S1

4. Establish a trunk to implement communication between the same VLAN of different switches

S1 (config) # interfacefastethernet 0/5 \ enter port S1 0/5

S1 (config-If) # switchportmode trunk \ set trunk

S2 (config) # interfacefastethernet 0/5

S2 (config-If) # switchportmode trunk

 

5. Test

Normal Network Communication

6. establish channels to achieve Load Balancing across multiple lines, improve bandwidth, and fault tolerance

Topology:

 

S1 (config) # interfacerange fastethernet 0/5-8

S1 (config-if-range) # switchportmode trunk

S1 (config-if-range) # channel-group1 mode on

S2 (config) # interfacerange fastethernet 0/5-8

S2 (config-if-range) # switchportmode trunk

S2 (config-if-range) # channel-group1 mode on

S2 # Show running-config

Interfacefastethernet0/5

Channel-group 1 mode on

Switchport mode trunk

 

Interfacefastethernet0/6

Channel-group 1 mode on

Switchport mode trunk

!

Interfacefastethernet0/7

Channel-group 1 mode on

Switchport mode trunk

!

Interfacefastethernet0/8

Channel-group 1 mode on

Experiment 2 sets up DHCP

1. 1. Set all PCs to automatically obtain IP addresses

2. 2. Set the route implementation DBCP

Router (config) # interfacefastethernet 0/1 access the 0/1 Interface

Router (config-If) # IPaddress 192.168.2.254 255.255.255.0

Router (config-If) # enable noshutdown

 

Router (config) # IP dhcppool rdhcp enter DHCP settings

Router (DHCP-config) # network192.168.1.0 255.255.255.0

Router (DHCP-config) # The default gateway for default-router192.168.1.254 Configuration

Router (DHCP-config) # dns-server202.106.0.20 to configure DNS

1. 3. Reserved static IP address 192.168.1.1-192.168.1.100

 

Router (config) # IP dhcpexcluded-address 192.168.1.1 192.168.1.100

# A Single IP Address indicates that an IP address is connected to an IP address. The space interval between the two IP addresses indicates the IP address segment.
