N-Ring Configuration (continued)
If N-Ring Mode is “Manager”, then VLAN ID can be set to a unique vlan id (1 ~ 4094). Default is 1.
If N-Ring Mode is “Manager”, then a pulldown allows selection as to whether the N-Ring ports are
members of the VLANs Tagged or Untagged ports. Default is Untagged.
Once these fields are filled in to meet the needs of the administrator’s network the changes may be saved by
clicking the Update button at the bottom of the page.
NOTES:
1. Since VLANs are implemented for security reasons as well as traffic flow, N-Ring only makes
minimal changes. It is up to the administrator to ensure that VLANs are configured correctly on the
N-Ring manager and all N-Ring members.
2. When the N-Ring manager and all N-Ring Members are in defaults, changing the N-Ring manager
to use a Tagged VLAN requires no user interaction to allow non-ring traffic to pass through the ring.
This works because changing to a Tagged VLAN does not remove the ring ports from the default
VLAN.
3. When the N-Ring manager and all N-Ring Members are in defaults, changing the N-Ring manager
to use an Untagged VLAN other than VID 1, requires the administrator to add non-ring ports to the
N-Ring VLAN to allow non-ring traffic to pass through the ring. This occurs because the N-Ring
ports must be removed from VID 1 because an untagged port may only be a member of one VLAN.
