## Configure Static Unicast Entry in Topology 1

For this procedure, you must first configure the VLAN. See Example Topolgy 1 for the topology for this procedure.

1. Configure the VLAN in switch 1.

       SEFOS# configure terminal
       SEFOS(config)# vlan 2
       SEFOS(config-vlan)# ports extreme-ethernet 0/3,0/15,0/19
       SEFOS(config-vlan)# exit
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface extreme-ethernet 0/15
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface extreme-ethernet 0/19
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# mac-address-table static unicast 00:1b:21:53:6e:55 vlan 2 interface ext 0/15
       SEFOS(config)# exit

2. Review the VLAN-related configurations.

       SEFOS# show vlan id 2
       Vlan database
       -------------------
       Vlan ID             : 2
       Member Ports        : Ex0/15, Ex0/19
       Untagged Ports      : None
       Forbidden Ports     : None
       Name                :
       Status              : Permanent
       -----------------------------------------------------------------

3. After the spanning tree topology settlement, send the tagged (VLAN 2) unicast data packet to host B from host A.
4. Check the learned MAC addresses.

       SEFOS# show mac-address-table
       Vlan     Mac Address          Type       Ports
       -----------------------------------------------
       2        00:1b:21:53:6d:b9    Learnt     Ex0/19
       2        00:1b:21:53:6e:55    Static     Ex0/15

       Total Mac Addresses Displayed: 2
