Shut down SLB-related switch ports on the switch.

Enter Global Configuration mode so you can shut down SLB-related switch ports on the switch.
```
SEFOS# configure terminal
```

Shut down switch ports connected to the client network.

SEFOS(config)# interface range extreme-ethernet 0/3-6
SEFOS(config-if-range)# shutdown
SEFOS(config-if-range)# exit

Shut down switch ports connected to the servers.

SEFOS(config)# interface range extreme-ethernet 0/15-18
SEFOS(config-if-range)# shutdown
SEFOS(config-if-range)# exit

Set up the interface address of the switch.

SEFOS(config)# interface vlan 1
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

Set up SLB entries.

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 the traffic distribution hash policy (if needed).

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

View the updated configuration.

SEFOS# show slb
