Configuring port-based VLANs

Considerations when configuring VLAN byte accounting
• 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 Table 67
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 67 for details.
• If a port's VLAN has byte accounting enabled, you cannot enable rate limiting on that port.
Similarly, if a port has rate limiting enabled, you cannot enable VLAN byte accounting on that
port's VLAN.
• Clearing the rate limiting counters using clear rate-limit counters will also clear VLAN
byte-accounting counters. It is recommended that when using rate limiting along with VLAN
byte accounting, use individual port rate limiting counters.
Configuring VLAN byte accounting
To enable VLAN accounting on a specified VLAN, use the following commands.
BigIron RX(config)# vlan 10
BigIron RX(config-vlan-10)# byte-accounting
Syntax: [no] byte-accounting
Displaying VLAN byte accounting information
To display VLAN accounting information for all VLANs configured on a router, use the show vlan
command as shown.
BigIron RX# show vlan
Configured PORT-VLAN entries: 2
Maximum PORT-VLAN entries: 512
Default PORT-VLAN id: 1
PORT-VLAN 1, Name DEFAULT-VLAN, Priority Level0
L2 protocols : NONE
Untagged Ports : ethe 1/1 to 1/40 ethe 2/1 to 2/4
PORT-VLAN 10, Name [None], Priority Level0
L2 protocols : NONE
Tagged Ports : ethe 1/2 to 1/5
Bytes received : 18527
To display VLAN accounting information for a specific VLAN, use the show vlan <vlan> command as
shown.
BigIron RX# show vlan 10
PORT-VLAN 10, Name [None], Priority Level0
L2 protocols : NONE
Tagged Ports : ethe 1/2 to 1/5
Bytes received : 5626
The Bytes received field displays the number of bytes received by all member ports of all VLANs
configured on the router.
