Configure Initial Settings

1. Verify the connections between the switches and hosts.

   See Switching Feature Topology.

   1. For the SEFOS-1 switch, verify:

      • Port 1 – Connected to host server A (IP address 20.0.0.10)

      • Port 2 – Connected to host server B (IP address 20.0.0.20)

      • Ports 21-22 – Connected to ports 21-22 on the SEFOS-2 switch

   2. For the SEFOS-2 switch, verify that port 1 is connected to host server C (IP address 20.0.0.30).
2. Connect to SEFOS.

   See Connect to SEFOS.

3. 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 extreme-ethernet 0/1-2 untagged extreme-ethernet 0/1-2
   SEFOS-1(config-vlan)# vlan active
   SEFOS-1(config-vlan)# exit

4. Bring up the interfaces on which the hosts are connected.

   SEFOS-1# configure terminal
   SEFOS-1(config)# interface range extreme-ethernet 0/1-2
   SEFOS-1(config-if-range)# switchport pvid 101
   SEFOS-1(config-if-range)# no shutdown
   SEFOS-1(config-if-range)# exit

5. 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

6. 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

7. Check the status of the interfaces.

   SEFOS-1# show interface status
   Port Status Duplex Speed Negotiation
   ---- ------ ------ ----- -----------
   Ex0/1 connected Full 10 Gbps Auto-Negotiation
   Ex0/2 connected Full 10 Gbps Auto-Negotiation
   ...
   Ex0/4 not connected Full 10 Gbps Auto-Negotiation
   SEFOS-1# show interface description
   Interface Status Protocol
   --------- ------ --------
   Ex0/1     up     up
   Ex0/2     up     up
   Ex0/3     down   down
   Ex0/4     down   down
   ...
   vlan101 up up

8. Ping host A (20.0.0.10) from the SEFOS-1 switch.

   The ping should be successful.

9. Check the MAC address entry.

   SEFOS-1# show mac-address-table
    
   Vlan    Mac Address         Type     Ports
   ----    -----------         ----     -----
   101     00:14:4f:6c:7d:e9   Learnt   Ex0/1
    
   Total Mac Addresses displayed: 1

   ---

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

   ---

10. 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.
11. 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 ex 0/21-22
    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, 0/21, 0/22.
