Port Mirroring Test Case

Language:

The Port Mirroring test is designed to test the data transmit/receive functionality in port mirroring mode.

The Port Mirroring test case running environment can be schematically represented as shown in the following figure.

To Set Up Port Mirroring Test Case

Configure the switch by executing the following steps.
1. Setup four VLANs: VLAN1, VLAN2, VLAN3 and VLAN4 on the switch, and ensure that each VLAN includes two switch ports.
2. Assign an IP address to VLAN1. Select one switch port of VLAN1 as administrator port and connect it to SUT.
3. Set the port which connects to NET3 of SUT in VLAN4 to mirror the port which connects to NET1 of SUT. Set the port which connects to NET4 of SUT in VLAN4 to mirror the port which connects to NET2 of SUT.
Configure the Test Manager by executing the following steps.
1. Setup the TM in manual mode. Select two links NET0 and NET1 as test links, and assign the IP address to each link by the TM.
2. Connect NET0 to the port of VLAN2, and NET1 to the port of VLAN3.
Configure the System Under Test by executing the following steps.
1. Setup the SUT in manual mode. Select five links NET0, NET1, NET2, NET3 and NET4 as test links, and assign the IP address to NET0, NET1 and NET2 by the SUT in manual mode.
2. Save the test type, NET3 and NET4 link name of SUT, NET0 and NET1 IP address of TM into /opt/SUNWhcts/etc/switch.conf file respectively.
3. Connect NET0 to the port of VLAN1, NET1 to the port of VLAN2, NET2 to the port of VLAN3, NET3 and NET4 to the ports of VLAN4.

Example 5

The following example displays how to set up a Port Mirroring test case.

For a switch, there are four VLANS: VLAN1, VLAN2, VLAN3, and VLAN4:

     . show vlan
      VLAN Name                        Status    Ports
      ---- -------------------------------- --------- --------------------
      ... ...
      5    VLAN1                        active    Gi1/1, Gi1/2
      30   VLAN2                        active    Gi1/11, Gi1/12
      40   VLAN3                        active    Gi1/21, Gi1/22
      50   VLAN4                        active    Gi1/31, Gi1/32
      The switch administration port IP address for VLAN1:

      .show int vlan 5
      Vlan5 is up, line protocol is up
        Hardware is Ethernet SVI, address is c471.fe8b.9bff (bia c471.fe8b.9bff)
        Internet address is 192.168.1.10/24
        MTU 9198 bytes, BW 1000000 Kbit, DLY 10 usec,
        ... ...
        The mirroring configuration:

        .show monitor
        Session 1
        ---------
        Type                   : Local Session
        Source Ports           :
            Both               : Gi1/11
        Destination Ports      : Gi1/31
            Encapsulation      : Native
                  Ingress      : Disabled
                 Learning : Disabled
        Filter Pkt Type        :
            RX Only       : Good
        ... ...

For SUT, there are four links net0, net1, net2, and net3 which has to be configured as test links.

The ethernet network switch certification test configuration file on SUT:
root@solairs:~# cat /opt/SUNWhcts/etc/switch.conf
... ...
# Port mirroring testing
# Argument 1: SUT nic interface linked to mirrored port outside test vlan
# Argument 2: TM nic ip address linked to port in test vlan
# Example: PM net0 10.10.10.10
PM net3 192.168.10.11
PM net4 192.168.11.11
... ...

For TM, there are two links net0 and net1 which has to be configured as test links.
