General Port Commands
the appropriate encap-type must be specified to distinguish the services on the port. Once an Ethernet port
has been configured for access mode, multiple services can be configured on the Ethernet port.
Access-uplink: Access-uplink ports are used to provide native Ethernet connectivity in service provider
transport or infrastructure network. This can be achieved by configuring port mode as access uplink. 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 access uplink port. It is supported only on 7210 SAS-M and 7210 SAS-T configured in
access-uplink mode.
Network: A network port participates in the service provider transport or infrastructure network when a
network mode is selected. When the network option is configured, the encap-type can be configured to
either null or dot1q.
Hybrid: A hybrid Ethernet port allows the combination of network and access modes of operation on a per-
VLAN basis and must be configured as either dot1q or QinQ encapsulation. When the hybrid port is
configured to the dot1q encapsulation, the user configures a SAP inside a service by providing the SAP ID
which must include the port-id value of the hybrid mode port and an unused VLAN tag value. The format is
<port-id>:qtag1. A SAP of format <port-id>:* is also supported. The user configures a network IP interface
under config>router>interface>port by providing the port name which consists of the port-id of the hybrid
mode port and an unused VLAN tag value. The format is <portid>:qtag1.
The user must explicitly enter a valid value for qtag1. The <port-id>:* value is not supported on a network
IP interface. The 4096 VLAN tag space on the port is shared among VLAN SAPs and VLAN network IP
interfaces. When the hybrid port is configured to QinQ encapsulation, the user configures a SAP inside a
service simply by providing the SAP ID which must include the port-id value of the hybrid mode port and
the outer and inner VLAN tag values.
The format is <port-id>:qtag1.qtag2. A SAP of format <port-id>: qtag1.* is also supported. The outer
VLAN tag value must not have been used to create an IP network interface on this port. In addition, the
qtag1.qtag2 value combination must not have been used by another SAP on this port. The user configures a
network IP interface under config>router>interface>port by providing the port name which consists of the
port-id of the hybrid mode port and a VLAN tag value. The format is <portid>:qtag1.*. An outer VLAN tag
qtag2 of * is used to create an IP network interface. In addition, the qtag1.qtag2 value combination must not
have been used on another SAP or IP network interface on this port.
The no form of this command restores the default.
Default network
