SAP configuration notes when operating the 7210-M in Access-
Uplink mode only
When provisioned in access-uplink mode, the following SAP configuration guidelines are
applicable.
The Table 4 provides details of SAP and service combinations allowed in access-uplink mode
Table 4: SAP and Service Combinations for 7210 SAS M in access-uplink mode
• ‘svc-sap-type’ parameter value determines the type of SAPs that are allowed to be
provisioned in a service.
• A physical port can have only one SAP to be part of one service. Multiple SAPS can be
defined over a physical port but each of these SAPs should belong to a different service.
• In the case of a service’s sap-type is specified as dot1q-preserve, all the SAPs configured
in the service must have the same VLAN ID. The outermost VLAN tag of the packets
received on access port is not stripped, when svc-sap-type is set to dot1q-preserve.
• Dot1q Default SAP cannot be configured when svc-sap-type is set to ‘any’
• When svc-sap-type is set to ‘any’ for a NULL SAP, the system processes and forwards
only packets with no VLAN tag (that is, untagged). All other packets with one or more
VLAN tags (even those with priority tag only) are not processed and dropped. Users can
use the service with svc-sap-type set to ‘null-star’, to process and forward packets with
one or more tags (including priority tag) on a null SAP.
• An ingress QoS policy and accounting policy is assigned per access uplink port and
cannot be assigned per access uplink SAP.
•The Default QinQ SAP processes only tagged packets received on a QinQ port. All
tagged packets that do not match the specific SAP tags configured on the same port are
