Use the following guidelines to configure a port-based access ingress QoS policy on the 7210 SAS-Mxp:
Delete all SAPs on the port or the LAG before changing between the sap-mode and port-mode options for the access-ingress-qos-mode command.
Perform the following steps before changing the access-ingress-qos-mode command to port-mode:
Reboot the node in sap-scale-mode high.
Ensure that resources are allocated to qos-access-ingress-resource.
Configure an access port using the config>port>ethernet>mode command with the access option specified.
If the config>port>ethernet>access-ingress-qos-mode command is set to port-mode, access ingress policy 1 is attached to the port by default. The policy can be replaced with a user-defined access ingress QoS policy provided that sufficient resources are available in the qos-access-port-ingress-resource slice.
Resource allocation from qos-access-port-ingress-resource has no restrictions. Resources can be allocated in sap-scale-mode low and high; however, allocating resources in sap-scale-mode low wastes resources because an access ingress QoS policy can only be attached in sap-scale-mode high.
Reset the user-defined access ingress QoS policy to 1 on the port before changing the access-ingress-qos-mode command to sap-mode.
If the access-ingress-qos-mode command is configured in the config>lag context, reset the user-defined access ingress QoS policy to 1 on the primary LAG member before changing the access-ingress-qos-mode command to sap-mode.
