Misconfigurations and Optimizations Report 869

If the same VLAN ID had been used on all three switches, for example ID=4, then 3Com Network Director would only list one VLAN in the Show VLANs toolbar and the Find dialog:

Accounts (ID=4)

A more likely use of inconsistent VLANs is shown below:

One router is using VLAN ID=2 for subnet A, the other router is using VLAN ID=3 for the same subnet. The VLANs with IDs 2 and 3 are in fact the same VLAN - subnet A. While this is a valid configuration, it is good practice to use the same VLAN ID consistently to identify a VLAN. 3Com Network Director will report this as a misconfiguration and will display these as two different VLANs.

To avoid this misconfiguration being reported in the future, and to avoid 3Com Network Director listing multiple VLANs for each real VLAN, the same VLAN ID should be configured on all switches.

Inconsistent VLAN 3Com Network Director will report a misconfiguration if the same VLAN naming (same VLAN ID) is configured on two different switches with different

names. It is good practice to use the same name consistently when configuring VLANs.
