Network protocol Analysis Experiment

Three-layer Switch configuration experiment

TCP/IP configuration experiment

1. Setting ip/subnet mask/gateway, DNS server, properties, Internet Protocol (TCP/IP), properties, local Area Connection

2. IP address (network number + host number)

Ipv4<32 bit > 0.0.0.0 ~ 255.255.255.255

Labeled Φa are Class address (beginning with 0),/8, 255.0.0.0

Φb class Address (beginning with 10),/16, 255.255.0.0

Φc class address (beginning with 110),/24, 255.255.255.0

Private address

Division of Subnets

Server Configuration Experiment

1. Web site/ftp site, Internet Information Services (IIS), Administrative Tools, control Panel

2. Common network commands:

Ping

Ipconfig

Arp

Netstat

Tracert

Route

Net

Nsloopup

Ftp

Cable making and integrated cabling experiment

1. Common Wired Transmission media

Linetype Interface
Twisted pair Wire RJ-45 interface, within 100 meters
Coaxial cable BNC interface
Fiber

2. Equipment = on-off device + DSP-4300 cable tester + linkware software

Direct connection 568B Standard at both ends for connecting different devices
Intersection line 568A Standard, end 568B Standard, for connecting the same device
Invert line Two-wire sequence opposite, used to connect network devices

Switch Configuration Experiment

1. Virtual network Technology (VLAN)

Used to isolate, split broadcast domains

#>switchport Access VLAN 10

#>ip address IP addresses subnet mask

#>ip Routing

2. Relay Technology (TRUNK)

802.1q standard for VLAN communication across switches

#>switchport mode trunk defaults to access

3. Problems that may exist in network transmission

Φ single point of failure

Φ Redundant link

Φ Loop

Φ Multi-frame replication and MAC Address Table instability

4. Spanning Tree Protocol (STP)

802.1D Standard, providing redundant links to solve network loop problems

5. Fast Spanning Tree Protocol (RSTP)

802.1W Standard, no delay forwarding

#>spanning-tree

#>no Spanning-tree

#>spanning-tree Mode STP/RSTP

#>show Spanning-tree

6. Aggregation Link (aggregate,ag)

No packet loss, balanced flow

#>show Aggregateport Summary

#>show Aggregateport load-balance

7. Switch port = One control port (console) + 24 x 10base-t/100base-tx RJ-45 Port

Router Configuration Experiment

1. Router Port = 2 Ethernet ports + 2 high-speed synchronous serial port + one control port (console) + 1 aux port

2. Configuration mode: User mode/Privileged mode/Global configuration mode/interface configuration mode/routing configuration mode/Line configuration mode

3. Routing-Direct, static, dynamic

4. Terminal equipment (DTE)/Data communication equipment (DCE)

5. #>show IP Interface Brief

#>show IP route

6. IP Access Control List (ACL)

#>access-list <1-99> (Standard)/<100-199> (extended) Permit/deny protocol name IP address anti-mask

#>ip Access-group <1-99> (Standard)/<100-199> (extended) in/out

Network protocol Analysis Experiment

1. Software: Winpcap, Ethereal

2. Agreement:

Ethernet

ip/ arp/ ICMP

tcp/ UDP

Ftp/telnet/http

Dns

Three-layer Switch configuration experiment

1. Configure VLAN-Configuration trunk-and configure VALN communication, activate routing protocol, authentication

2. #>show Running-config
