<hex 0x1-0xffff> | use_inner_priority [enable | disable] | add_inner_tag [<hex 0x1-0xffff> |
disable]}(1)
Parameters
<portlist> - Specify a range of ports to configure.
all - Specify to configure all ports.
role - Specify the port role in Q-in-Q mode.
uni - The port is connecting to the customer network.
nni - The port is connecting to the service provider network.
missdrop - Enable or disable the tagged packet drop that does not match any assignment rule in
the Q-in-Q profile.
enable - Enable miss drop of ports.
disable - Disable miss drop of ports.
outer_tpid - Specify the outer-TPID of a port.
<hex 0x1-0xffff> - Specify the outer-TPID of a port.
use_inner_priority - Specify whether to use the priority in the C-VLAN tag as the priority in the
S-VLAN tag. By default, the setting is disabled.
enable - Specifies that the use of the inner priority will be enabled.
disable - Specifies that the use of the inner priority will be disabled.
add_inner_tag - Specify whether to add inner tag for ingress untagged packets. If set, the inner
tag will be added for the ingress untagged packets and, therefore, the packets that egress to
the NNI port will be double tagged.
<hex 0x1-0xffff> - Enter the inner tag value here.
disable - Specifies that only the s-tag will be added for ingress untagged packets.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
