## Set Up Switch B

Shut down SLB-related switch ports on the switch.

1. Shut down the uplinks connected to switch A.

       SEFOS# configure terminal
       SEFOS(config)# interface range extreme-ethernet 0/11-12
       SEFOS(config-if-range)# shutdown
       SEFOS(config-if-range)# exit

2. Shut down the switch ports connected to the servers.

       SEFOS(config)# interface range extreme-ethernet 0/15-21
       SEFOS(config-if-range)# shutdown
       SEFOS(config-if-range)# exit

3. Disable GVRP and GMRP.

       SEFOS(config)# set gvrp disable
       SEFOS(config)# set gmrp disable

4. Set up spanning tree so that it works with two separate VLANs.

       SEFOS(config)# spanning-tree mst configuration
       SEFOS(config-mst)# name example3
       SEFOS(config-mst)# revision 1
       SEFOS(config-mst)# instance 1 vlan 3
       SEFOS(config-mst)# instance 2 vlan 4
       SEFOS(config-mst)# exit

5. Set up the server VLAN.

   Set up the server VLANs on up-links.

       SEFOS(config)# vlan 3
       SEFOS(config-vlan)# port extreme-ethernet 0/11
       SEFOS(config-vlan)# exit
       SEFOS(config)# vlan 4
       SEFOS(config-vlan)# port extreme-ethernet 0/12
       SEFOS(config-vlan)# exit

   Set up the VLAN switch port access to server networks.

       SEFOS(config)# interface range extreme-ethernet 0/15-18
       SEFOS(config-if-range)# switchport access vlan 3
       SEFOS(config-if-range)# exit
       SEFOS(config)# interface range extreme-ethernet 0/19-21
       SEFOS(config-if-range)# switchport access vlan 4
       SEFOS(config-if-range)# exit

   Set up the VLAN interface addresses of server VLANs.

       SEFOS(config)# interface vlan 3
       SEFOS(config-if)# shutdown
       SEFOS(config-if)# ip address 192.0.0.101 255.255.255.0
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface vlan 4
       SEFOS(config-if)# shutdown
       SEFOS(config-if)# ip address 192.1.0.101 255.255.255.0
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# end
