5.16.2 Monitor VLAN Ports

The VLAN Port Status for Combined Users page provides VLAN port status.

Figure 5-61. VLAN Port Status for Combined Users

The VLAN Port Status for Combined Users page has the following parameters:

  • VLAN User: Various internal software modules may use VLAN services to configure VLAN port configuration on the fly. The drop-down list on the right allows for selecting between showing VLAN memberships as configured by an administrator (Admin) or as configured by one of these internal software modules. The Combined entry shows a combination of the administrator and internal software modules configuration, and basically reflects what is configured in the hardware.

    If a given software module has not overridden any of the port settings, then the text No data exists for the selected user is shown in the table.

  • Port: The logical port for the settings contained in the same row
  • Port Type: Shows the port type (Unaware, C-Port, S-Port, and S-Custom-Port.) that a given user wants to configure on the port. The field is empty if not overridden by the selected user.
  • Ingress Filtering: Shows if a given user wants ingress filtering enabled. The field is empty if it is not overridden by the selected user.
  • Frame Type: Shows the acceptable frame types (All, Tagged, and Untagged) that a given user wants to configure on the port. The field is empty if not overridden by the selected user.
  • Port VLAN ID: Shows the Port VLAN ID (PVID) that a given user wants the port to have. The field is empty if not overridden by the selected user.
  • Tx Tag: Shows the Tx Tag requirements (Tag All, Tag PVID, Tag UVID, Untag All, Untag PVID, and Untag UVID) that a given user has on a port. The field is empty if not overridden by the selected user.
  • Untagged VLAN ID: If Tx Tag is overridden by the selected user and is set to Tag or Untag UVID, then this field shows the VLAN ID the user wants to tag or untag on egress. The field is empty if it is not overridden by the selected user.
  • Conflicts: Two users may have conflicting requirements to a port's configuration. For instance, one user may require all frames to be tagged on egress while another requires all frames to be untagged on egress. Since both users cannot win, this gives rise to a conflict, which is solved in a prioritized way. The Administrator has the least priority. Other software modules are prioritized according to their position in the drop-down list: The higher in the list, the higher priority. If conflicts exist, it is displayed as Yes for the Combined user and the offending software module. The Combined user reflects what is configured in hardware.
