5.7.3 - VLAN Assignment Issues

Flashcards on VLAN assignment issues.

Why should you ping the loopback address and the host's own IP address?

To verify TCP/IP is working and the host's IP is correctly configured.

Why should you ping the default gateway?

To verify that it is contactable.

If you cannot ping the default gateway, but you can rule out issues with the host or switch router, what should you check?

Check that the patch cable for the workstation's wall port is connected to the correct switch port and for any other physical cable issues.

If you cannot ping any remote hosts, what should you do?

Verify the switch and router configuration.

Why would you use traceroute?

To determine the cause of the problem when you can ping some remote hosts but not others.

When you configure a VLAN, what is the result?

The switch ports assigned to that VLAN are in a segmented network, and the VLAN is likely to be assigned its own subnet address.

What parameters must be appropriately configured for a device connecting to a port in the VLAN?

IP address, subnet mask, default gateway, and DNS servers.

How is the VLAN's router (default gateway) likely to be configured?

A type of virtual interface or a Switched Virtual Interface (SVI).

If there are continuing problems after verifying the cable connection, what should you check regarding the patch panel?

Verify that the patch panel labeling correctly identifies the wall jack that the computer is connected to.

Where are DHCP and DNS servers typically located in relation to VLANs?

They will be in a server VLAN, and hosts in the client VLAN must use the default gateway to contact them.

In a setup where DHCP/DNS servers are in a server VLAN, what additional configuration is required?

A DHCP relay must also be configured.
