Configuring static MAC address entries

Introduction

The following information uses an example to describe the basic procedure for configuring static MAC address entries.

Network configuration

As shown in Figure 1, for secure communication between users in VLAN 100 and the server or extranet through Switch A, perform the following tasks:

·     Assign GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 to VLAN 100.

·     Add a static MAC address entry on Switch A to bind the server MAC address to GigabitEthernet 1/0/2.

Figure 1 Network diagram

‌

Procedure

To Configure Switch A:

# Create VLAN 100.

<Switch A> system-view

[Switch A] vlan 100

[Switch A-vlan100] quit

# Assign GigabitEthernet 1/0/2 to VLAN 100.

[Switch A] interface gigabitethernet 1/0/2

[Switch A-GigabitEthernet1/0/2] port access vlan 100

[Switch A-GigabitEthernet1/0/2] quit

# Configure GigabitEthernet 1/0/3 (port facing the LAN switch) as a trunk port, and assign the port to VLAN 100.

[Switch A] interface gigabitethernet 1/0/3

[Switch A-GigabitEthernet1/0/3] port link-type trunk

[Switch A-GigabitEthernet1/0/3] port trunk permit vlan 100

[Switch A-GigabitEthernet1/0/3] quit

# Add a static entry for MAC address 0033-0033-0033 on GigabitEthernet 1/0/2 that belongs to VLAN 100.

[Switch A] mac-address static 0033-0033-0033 interface gigabitethernet 1/0/2 vlan 100

Verifying the configuration

# Use ping operations to verify that any 10.0.0.0/24 host in VLAN 100 can communicate with the server.

<Sysname> ping 10.0.0.9

Ping 10.0.0.9 (10.0.0.9): 56 data bytes, press CTRL+C to break

56 bytes from 10.0.0.9: icmp_seq=0 ttl=254 time=2.137 ms

56 bytes from 10.0.0.9: icmp_seq=1 ttl=254 time=2.051 ms

56 bytes from 10.0.0.9: icmp_seq=2 ttl=254 time=1.996 ms

56 bytes from 10.0.0.9: icmp_seq=3 ttl=254 time=1.963 ms

56 bytes from 10.0.0.9: icmp_seq=4 ttl=254 time=1.991 ms

 

--- Ping statistics for 10.0.0.9 ---

5 packet(s) transmitted, 5 packet(s) received, 0.0% packet loss

round-trip min/avg/max/std-dev = 1.963/2.028/2.137/0.062 ms

# Verify that the static MAC address entry has been added.
