Set Up Switch A

Shut down SLB-related switch ports on the switch.

1. Shut down switch ports connected to the clients.

   SEFOS# configure terminal
   SEFOS(config)# interface range extreme-ethernet 0/1-4
   SEFOS(config-if-range)# shutdown
   SEFOS(config-if-range)# exit
   

2. Shut down uplink ports to switch B.

   SEFOS(config)# interface range extreme-ethernet 0/9-10
   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 client VLAN.

   Set up VLAN switch port access to the client network.

   SEFOS(config)# vlan 2
   SEFOS(config-vlan)# exit
   SEFOS(config)# interface range extreme-ethernet 0/1-4
   SEFOS(config-if-range)# switchport access vlan 2
   SEFOS(config-if-range)# exit
   

   Set up the interface address of the client VLAN.

   SEFOS(config)# interface vlan 2
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# ip address 20.0.0.100 255.255.255.0
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# exit
   

6. Set up the server VLAN.

   Set up the server VLANs on uplinks.

   SEFOS(config)# vlan 3
   SEFOS(config-vlan)# port extreme-ethernet 0/9
   SEFOS(config-vlan)# exit
   SEFOS(config)# vlan 4
   SEFOS(config-vlan)# port extreme-ethernet 0/10
   SEFOS(config-vlan)# exit
   

   Set up the VLAN gateway interface addresses of server subnets.

   SEFOS(config)# interface vlan 3
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# ip address 192.0.0.100 255.255.255.0
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# exit
   SEFOS(config)# interface vlan 4
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# ip address 192.1.0.100 255.255.255.0
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# exit
   

7. Set up SLB entries.

   Set up the first SLB group.

   SEFOS(config)# slb 10.10.10.0 255.255.255.0 192.0.0.1,192.0.0.2,192.0.0.3
   SEFOS(config)# slb standby 10.10.10.0 255.255.255.0 192.0.0.4
   

   Set up the second SLB group.

   SEFOS(config)# slb 11.11.11.0 255.255.255.0 192.1.0.1,192.1.0.2,192.1.0.3
   

8. Set the traffic distribution hash policy (if needed).

   SEFOS(config)# slb policy src-ip
   SEFOS(config)# end
   

9. View the updated configuration.

   SEFOS# show slb

   192.1.0.3        ----  --:--:--:--:--:-- ---- IDLE
   

   The preceding output shows that all active servers are in idle state (not reachable from the switch) and that the standby server is also unreachable from the switch (marked as down in the Comments column).
