Verify the connections between the switches and hosts.
See Switching Feature Topology.
1. For the SEFOS-1 switch, verify the connections:
  - Ports 1-4 – Connected to ports 1-4 on the SEFOS-2 switch
  - Port 25 – Connected to host server A (IP address 20.0.0.10)
  - Ports 26 – Connected to host server B (IP address 20.0.0.20)
2. For the SEFOS-2 switch, verify that port 25 is connected to host server C (IP address 20.0.0.30).

Connect to SEFOS.
See Connect to SEFOS.

Create a VLAN and add the host ports as member ports of the VLAN.

SEFOS-1# configure terminal
SEFOS-1(config)# vlan 101
SEFOS-1(config-vlan)# ports xl-ethernet 0/25-26 untagged xl-ethernet 0/25-26
SEFOS-1(config-vlan)# vlan active
SEFOS-1(config-vlan)# exit

Bring up the interfaces on which the hosts are connected.

SEFOS-1# configure terminal
SEFOS-1(config)# interface range xl-ethernet 0/25-26
SEFOS-1(config-if-range)# switchport pvid 101
SEFOS-1(config-if-range)# no shutdown
SEFOS-1(config-if-range)# exit

Configure the IP address on VLAN 101 and bring up the interface.

SEFOS-1# configure terminal
SEFOS-1(config-int)# interface vlan 101
SEFOS-1(config-int)# ip address 20.0.0.1 255.0.0.0
SEFOS-1(config-int)# no shutdown
SEFOS-1(config-int)# exit

Verify that the VLAN 101 interface is up.

SEFOS-1# show ip interface
vlan1 is down, line protocol is down
Internet Address is 10.0.0.1/8
Broadcast Address 10.255.255.255
vlan101 is up, line protocol is up
Internet Address is 20.0.0.1/8
Broadcast Address 10.255.255.255

Check the status of the interfaces.

SEFOS-1# show interface status
Port Status Duplex Speed Negotiation Capability
---- ------ ------ ----- ----------- ----------
Xl0/1 not connected Full 10 Gbps Auto-Negotiation Auto-MDIX on
Xl0/2 not connected Full 10 Gbps Auto-Negotiation Auto-MDIX on
...
Xl0/25 connected Full 10 Gbps Auto-Negotiation Auto-MDIX on
Xl0/26 connected Full 10 Gbps Auto-Negotiation Auto-MDIX on

SEFOS-1# show interface description

Xl0/26 up up

vlan101 up up

Ping host A (20.0.0.10) from the SEFOS-1 switch.
The ping should be successful.

Check the MAC address entry.

SEFOS-1# show mac-address-table
Vlan    Mac Address         Type     Ports
----    -----------         ----     -----
101     00:14:4f:6c:7d:e9   Learnt   Xl0/25
Total Mac Addresses displayed: 1

Note - The MAC address displayed must correspond to the MAC address of host A.

Repeat Step 3 through Step 5 on the SEFOS-2 switch to bring up the required ports and configure the IP address of VLAN 101 to 20.0.0.2.

Configure the topology.
To configure the topology, all of the interfaces should be up. If they are not up, use the no shutdown command to bring up the ports.
```
SEFOS-1# configure terminal
SEFOS-1(config)# interface range xl 0/1-2
SEFOS-1(config-if-range)# switchport pvid 101
SEFOS-1(config-if-range)# no shutdown
SEFOS-1(config-if-range)# end
```
In both switches, ensure that the following interfaces are up: 0/1, 0/2, 0/25, 0/26.
