Configuring a Service Access Point Profile
The ethernet-service sap-profile command is used to create a VLAN Stacking service access point (SAP)
profile. The following command parameters define the traffic engineering attributes that are applied to
customer traffic that is accepted on UNI ports associated with the SAP profile:
A default profile, named “default-sap-profile”, is automatically assigned to the SAP at the time the SAP is
created (see “Configuring a VLAN Stacking Service Access Point” on page 35-15). It is only necessary to
create a new profile to specify different attribute values if the default profile values (see above) are not
sufficient.
The following command provides an example of creating a new SAP profile to specify a different method
for mapping the SVLAN priority value:
-> ethernet-service sap-profile map_pbit priority map-inner-to-outer-p
In this example the map_pbit profile specifies priority mapping of the CVLAN inner tag 802.1p value to
the SVLAN outer tag value. The other attributes in this profile are set to their default values.
To delete a SAP profile, use the no form of the ethernet-service sap-profile command. For example, the
following command deletes the map_pbit profile:
-> no ethernet-service sap-profile map_pbit
Consider the following when configuring a SAP profile:
Profile Attribute Command Parameters Description
Ingress bandwidth
sharing
shared | not shared Whether or not ingress bandwidth is shared
across UNI ports and CVLANs.
Ingress rate limiting ingress-bandwidth The rate at which customer frames ingress on
UNI ports.
Egress rate limiting egress-bandwidth The rate at which customer frames egress on UNI
ports.
Bandwidth assignment bandwidth not-assigned Allows QoS policy rules to override profile
attribute values for bandwidth. By default, the
profile bandwidth values take precedence and are
allocated additional QoS system resources.
Double-tag or translate cvlan | preserve |
translate
Determines if a customer frame is tagged with
the SVLAN ID (double-tag) or the CVLAN ID is
changed to the SVLAN ID (translate) when the
frame is encapsulated for tunneling. Double-tag
is used by default.
Priority mapping map-inner-to-outer-p |
map-dscp-to-outer-p |
fixed
Determines if the CVLAN (inner tag) 802.1p or
DSCP value is mapped to the SVLAN (outer tag)
802.1p value or if a fixed priority value is used
for the SVLAN 802.1p value. Priority mapping is
set to a fixed rate of zero by default.
Priority assignment priority not-assigned Allows QoS policy rules to override profile
attribute values for priority. By default, profile
priority values take precedence and are allocated
additional QoS system resources.
