Iii. Experiment steps

1. Connect the link based on the Topology

2. VLAN Division

1) vlan2 and vlan3 are divided on S1.

S1 (config) # VLAN 2

S1 (config-VLAN) # exit

S1 (config) # VLAN 3

S1 (config-VLAN) # exit

S1 (config) # int range F0/1-2

S1 (config-if-range) # switchport Mode Access

S1 (config-if-range) # switchport access VLAN 2

S1 (config-if-range) # exit

S1 (config) # int range F0/3-4

S1 (config-if-range) # switchport Mode Access

S1 (config-if-range) # switchport access VLAN 3

2) vlan2 and vlan3 are divided on S2.

S2 (config) # VLAN 2

S2 (config-VLAN) # exit

S2 (config) # VLAN 3

S2 (config-VLAN) # exit

S2 (config) # int ran F0/1-2

S2 (config-if-range) # SWI m

S2 (config-if-range) # sw ac vlan 2

S2 (config-if-range) # exit

S2 (config) # int ran F0/3-4

S2 (config-if-range) # SW m

S2 (config-if-range) # sw ac vlan 3

S2 (config-if-range) # exit

3. Configure an Ethernet channel for the link between S1 and S2 to achieve redundant backup and load balancing.

1) Configure trunk on S1 and ethernetchannel

S1 (config) # int range F0/22-24

S1 (config-if-range) # SW mode trunk

S1 (config-if-range) # channel-group 1 mode on

S1 (config-if-range) # No Shutdown

2) Configure trunk on S2 and ethernetchannel

S2 (config) # int range F0/22-24

S2 (config-if-range) # SW mod trunk

S2 (config-if-range) # channel-group 1 mode on

S2 (config-if-range) # No Shutdown

4. Configure IP Address: 192.168.2.1/24 on pC1 and IP Address: 192.168.2.2/24 ON Pc5

Configure IP Address: 192.168.3.1/24 on pc4 and IP Address: 192.168.3.2/24 on pc8

Ping test, communication between the same VLAN is allowed

1) pC1 Ping Pc5

2) pc4 Ping pc8

5. Configure the DHCP address pool on the vrodhcp DHCP, and assign the IP address other than the specified IP address to the PC of the VLAN.

1) configure the address pool of vlan2 on DHCP

DHCP (config) # int F0/0

DHCP (config-If) # IP add 192.168.2.254 255.255.255.0

DHCP (config-If) # No Shutdown

DHCP (config) # ip dhcp pool vlan2_pool

DHCP (DHCP-config) # network 192.168.2.0 255.255.255.0

DHCP (DHCP-config) # default-router 192.168.2.254

DHCP (config) # ip dhcp excluded-address 192.168.2.1 192.168.2.2

2) Port F0/10 is divided into vlan2 on S1, which is used to allocate addresses to the PCs in vlan2.

S1 (config) # int F0/10

S1 (config-If) # switchport acc vlan 2

3) set PC2 and PC6 to use DHCP to dynamically obtain IP addresses.
