Usage Guidelines
•
A DHL session has to be created before a VLAN-MAP can be configured.
•
When the DHL session is active, the common VLAN that both the dual homed links belong to is
treated as a protected VLAN. The VLAN contaning only one dual homed link is treated as an unpro-
tected VLAN. Traffic is forwarded only on the dual homed links belonging to the protected VLAN.
•
If a VLAN is removed globally and if the VLAN belongs to a particular dual homed link, then the
VLAN will automatically be removed from the dual homed link.
•
If one dual homed link, for example linkA, is moved out of a protected VLAN, then the VLAN
becomes unprotected and the VPA is removed from the second dual homed link, for example linkB.
•
If the admin state of a VLAN is changed to disabled, and if the VLAN is part of a protected VLAN,
then the disabled VLAN is removed from the operational DHL VLAN list but will be present in the
protected VLAN list.
•
If the admin state of a dual homed link, for example linkA, is changed to disabled, then the protected
VLANs of the disabled linkA is moved to the other link, for example linkB. When linkA is re-enabled,
then the VLANs are moved back to linkA.
•
If the VLAN-MAP of linkB is removed, then the VPAs for the linkB will also be removed and the
VLANs configured on linkB is moved to linkA.
•
If a VLAN is configured as default on one dual homed link, for example linkA, then the same VLAN
cannot be configured as tagged on the other link, for example linkB.
