VLAN Tips

For each VLAN created with an IP address, an associated entry is also generated. Therefore, it is critical to verify that these entries exist. If any of the entries are missing, the system configuration may be corrupted. It is recommended to delete and re-create the VLAN.. Table 8-1 lists the VLAN entries and Table 8-2 lists useful CLI commands.
