Jumbo Frame Test Case
The Jumbo Frame test case is designed to verify the jumbo frame functionality supported by the switch. To do this, the switch, SUT and TM must be configured with support to jumbo frame.
The Jumbo Frame test case running environment can be schematically represented as shown in the following figure.
Figure 10 Jumbo Frame Test Case
To Set Up Jumbo Frame Test Case
- Configure the switch by executing the following steps.
- Setup three VLANs: VLAN1, VLAN2 and VLAN3 on the switch, and ensure that each VLAN includes two switch ports.
- Assign an IP address to VLAN1. Select one switch port of VLAN1 as administrator port and connect it to SUT.
- Set the Maximum Transmission Unit (MTU) size of the switch ports supported for each port in VLAN2 and VLAN3.
- Configure the Test Manager by executing the following steps.
- 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.
- Connect NET0 to the port of VLAN2, and NET1 to the port of VLAN3.
- Configure the System Under Test by executing the following steps.
- Setup the SUT in manual mode. Select three links NET0, NET1 and NET2 as test links, and assign the IP address to the each link by the SUT.
- Save the test type, NET1 and NET2 IP address of SUT, NET0 and NET1 IP address of TM and switch ports MTU size into /opt/SUNWhcts/etc/switch.conf file respectively.
- Connect NET0 to the port of VLAN1, NET1 to the port of VLAN2, NET2 to the port of VLAN3.
The following example displays how to set up a Jumbo Frame test case.
For a switch, there are three VLANS: VLAN1, VLAN2 and VLAN3:
. 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 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, ? ?
