1.3 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.
Port modes available for configuration on a 7210 SAS node are determined by the
current mode of operation of the router.

1. Supports MPLS uplinks only and implicitly operates in network mode
2. By default, the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C boot up in the
operation. These platforms also allow the use of
configuration), which provides the option to use Layer 2 uplinks instead of IP/MPLS uplinks to the
network core, similar to the 7210 SAS-K 2F1C2T router.
3. Implicitly operates in network
4. See section 1.3 for information about port mode configuration
• 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
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
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.
