Troubleshooting VLANs

In this section, you will get acquainted with some of the possible scenarios ofproblemsthat may occur in VLANs.

IP addressing issues with VLANs

VLANs have taught us that every VLAN is characterized byaunique IP subnet. Thus, if two devices in the same VLAN have different subnet addresses, then they cannot communicate. These are common problems and their solutions require that incorrect configurations should be identified and replaced by correct configurations. In the aforementioned situation, the incorrect subnet address must be replaced with a correct subnet address. Next, the ping command confirms the solution you implemented.

Note

You can learn more about VLANs and troubleshooting VLANs from http://www.ciscopress.com/articles/article.asp?p=2181837&seqNum=9.
