Sample Test Cases for Protocol Testing of Network Devices

Test Name	Test Cases
1VLAN on 1 Switch	Build two different VLANs. Check the visibility between hosts on different VLANs
3Symmatric VLANs on 1 switch	Create three different asymmetric VLANs. Check the visibility between hosts
Spanning Tree: Root Path Cost Variation	Test how the Root Path Cost changes after a topology variation
Spanning Tree: Port Blocking	Check how spanning tree protocol avoids formation of cycles in the network, blocking redundant links, in presence of VLANs too
Different Root Bridge for Different MSTI	Show that each MSTI can have different Root Bridge
Visibility between different STP Regions	With same VLANs check visibility between different STP regions
Telephone switch Performance	Generate 1000 telephone calls and check whether the telephone switch still operates or its performance degrades
Negative test for device	Enter the incorrect key and check the user for authentication. It should not allow user to access
Line speed	Check the device operating at 10Gbps speed, utilizing all the available bandwidth to handle incoming traffic
Protocol conversation rate	Track a TCP conversation between two devices and verify that each device engaged in a correct behavior
Response time for session initiation	Measure the response time of a device to an invite request for session initiation
