VLAN
Byte Accounting
To enable your BigIron RX 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.
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. See Table 11.1 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. See Table 11.1 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
