7210 SAS port modes

Unless explicitly noted, the phrase ‟port mode” refers to the current port configuration of the 7210 SAS node. The 7210 SAS platform supports the configuration of the following port modes:

• access port mode

  Access ports are configured for customer-facing traffic if Service Access Points (SAPs) are required. The appropriate encapsulation type must be configured to distinguish the services on the port; services are configured on the port based on the encapsulation value.

  Access ports can be configured on all the 7210 SAS platforms.

• access-uplink port mode

  Access-uplink ports provide native Ethernet connectivity in service provider transport or in an infrastructure network. With this option, the encap-type can be configured to only QinQ. Access-uplink SAPs, which are QinQ SAPs, can only be configured on an access-uplink port to allow the operator to differentiate multiple services being carried over a single uplink port.

  This is the default port mode of a 7210 SAS node in the access-uplink mode of operation.

• network port mode

  Network ports are configured for network-facing traffic in the service provider transport or infrastructure network, and provide IP/MPLS uplinks.

  This is the default port mode of a 7210 SAS node in the network or standalone mode of operation.

• hybrid port mode

  Hybrid ports are configured for access and network facing traffic, and allow a single port to operate in both access and network modes.

Port modes available for configuration on a 7210 SAS node are determined by the current mode of operation of the router.

Table: Supported port modes by mode of operation lists the port mode configuration support per 7210 SAS mode of operation.

The following table lists the port mode configuration supported by the 7210 SAS product family. See the appropriate Interface Configuration Guide for more information about configuring the port modes for a specific platform.
