Interfaces
When the hybrid port is configured to the dot1q 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 an unused
VLAN tag value. The format is <port-id>:qtag1. A SAP of format <port-id>:* 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 <port-
id>: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 net-
work 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 <port-
id>: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.
