configure dot1q tagnesting ports
configure dot1q tagnesting {<vlanid> | <vlanid_range>} [off | pop | push
<new_vlanid> {priority <priority>}] ports <portlist> {egress | ingress}
Description
Configures the VLAN tag nesting attributes for a PoS or ATM port. Currently, the command is only
supported for PoS and ATM ports.
Syntax Description
Default
By default, tag nesting is off for all VLAN IDs. If the
egress/ingress
keywords are omitted, the
direction defaults to
egress
. Additionally, if the
egress/ingress
keywords are omitted and a tag push
operation is configured, a corresponding tag pop operation is automatically configured for the
ingress
direction. Similarly, if the
egress/ingress
keywords are omitted and tag nesting is configured off, it is
disabled in both directions.
Usage Guidelines
The command provides support for nested 802.1Q tags by allowing a tag push/pop attribute to be
associated with a VLAN ID. The push attribute indicates that a new tag is to be added to the frame,
while the pop attribute indicates that the top-level tag is to be removed from the frame. The
push
keyword indicates that a new tag is to be added to frames containing the specified
vlanid
or one of the
VLAN IDs in the specified
vlanid_range
. The syntax of the
vlanid_range
parameter is
start_vlanid-end_vlanid
. Omission of the
vlanid
/
vlanid_range
parameter indicates that the
command settings should be applied to all VLAN IDs. For push operations, the new tag added to
frames contains the specified
new_vlanid
.
The
pop
keyword indicates that the top-level tag is to be removed from frames when the tag contains
any of the specified VLAN IDs. Tag operations may be performed in either
egress
(to the PoS link) or
ingress
directions.
When a new tag is pushed, an option is available to allow the 802.1p priority of the frame to be either
preserved or set to a configured value. The priority keyword indicates that the 802.1p priority field is to
vlanid
Specifies that the tag nesting will be performed on the frames containing the
VLAN ID given.

Specifies that the tag nesting will be performed on the frames containing
VLAN ID values in the given range.

pop
Deletes a tag from the frame.
push
Adds a tag to the frame.
new_vlanid
Specifies the VLAN ID of the tag to be added or deleted from the frame.
priority
Allows you to set the 802.1p priority value.
portlist
Specifies the port number(s).
egress
Specifies that the tag operations are to be performed to the PPP link.
ingress
Specifies that the tag operations are to be performed from the PPP link.
