VLAN byte accounting

To enable your device to perform accounting of the number of bytes received by all the member
ports of a VLAN. This includes the preamble and the minimum inter-frame gap in Ethernet. The byte
counts can then be viewed using the show vlan command. VLAN byte accounting is disabled by
default.

add ports to that VLAN and specify if the ports are tagged or untagged.
BigIron RX(config-vlan-2)# untag e 1/9 to 1/16
BigIron RX(config-vlan-2)# tagged e 1/1 to 1/8
The example above configures a port-based VLAN, VLAN 2. It adds Ethernet ports 1/9 through
1/16 as untagged ports and ports 1/1 through 1/8 as tagged ports. Since ports 1/9 through
1/16 are untagged, they can be members of VLAN 2 only, while ports 1/1 through 1/8 are
tagged ports and can be members of other VLANs.
NOTE
In the configuration above, ports 1/9 – 1/16 are explicitly removed from the default VLAN
since they are configured as untagged ports; while port 1/1 – 1/8 are still members of the
default VLAN.
Syntax: [no] untagged | tagged ethernet <slot-number>/<port-number> [to
<slot-number>/<port-number> | ethernet <slot-number>/<port-number>]
The untagged and tagged parameter removes ports from the default VLAN and puts them in
the port-based VLAN. The untag command also allows the ports to process packets that do not
contain 802.1q tagging.
The tagged parameter allows the device to add a four-byte tag 802.1q tag to the packets that
go through the tagged ports. It also allows the ports to be members of other VLANs.
Enter the port that you want to assign to the VLAN for the ethernet
<slot-number>/<port-number> parameter. You can add trunk group ports to the VLAN by
entering the trunk group's the primary port. A trunk group's primary port is the port with the
lowest number in the trunk group. When you add the trunk group's primary port, all the ports
on the trunk group become members of the VLAN.
Use the no form of the command to remove the ports from a VLAN. For example.
BigIron RX(config)# vlan 4
BigIron RX(config-vlan-4)# no untag ethernet 1/11
VLAN byte accounting cannot be enabled for the default or control VLANs.
The number of VLANs on which byte accounting can be enabled system-wide is restricted by
the number of VLANs with byte accounting enabled on a given packet processor and the
number of rate limiting policies enabled on the same packet processor ports. Refer to
for details.
On a given packet processor, the total number of VLANs with byte accounting enabled and the
number of ACL-based and VLAN-based rate limiting policies is dependent on the interface
module. Refer to Table 64 for details.
