The 7210 SAS VLAN ranges (or dot1q range SAPs) provide a mechanism to group a range of VLAN IDs as a single service entity. This allows the operator to provide the service treatment (forwarding, ACL, QoS, accounting, and others) to the group of VLAN IDs as a whole.
Dot1q range SAPs are supported on all 7210 SAS platforms as described in this document.
Grouping a range of VLAN IDs to a SAP is supported only for Virtual Leased Line (VLL) Ethernet services.
