15.3 Typical Configuration Examples

PC1
MAC 00-01-11-11-11-11
Scenario:
Four PCs as shown in the above figure connect to port 1/5、1/7、1/9、1/11 of Chassis Switch, all the four PCs
belong to the default VLAN1. As required by the network environment, dynamic learning is enabled. PC1
holds sensitive data and can not be accessed by any other P C that is in anot her physical segment; PC2 and
PC3 have static mapping set to port 7 and port 9, respectively.
The configuration steps are listed below:
1. Set the MAC address 00-01-11-11-11-11 of PC1 as a filter address.
XGS 3-42000R(config)#mac-address-table static 00-01-11-11-11-11 discard vlan 1.
2. Set the static mapping relationship for PC2 and PC3 to port 7 and port 9, respectively.
XGS 3-42000R(config)#mac-address-table static 00-01-22-22-22-22 interface ethernet 1/7 vlan 1
XGS 3-42000R(config)#mac-address-table static 00-01-33-33-33-33 interface ethernet 1/9 vlan 1

15.4 MAC Table Troubleshooting

Using the show mac-address-table command, a port is found to be failed t o learn the MA C of a device
connected to it. Possible reasons:
 The connected cable is broken.
 Spanning Tree is enabled and the port is in "discarding" status; or the device is just connected to the
port and Spanning Tree is still under calculation, wait until the Spanning Tree calculation finishes, and
the port will learn the MAC address.
 If not the problems mentioned above , please check for the Chassis Switch port and contact technical
support for solution.
