Configuring port-based VLANs
11
Maximum number of rate limiting policies and VLANs with byte accounting
The maximum number of ACL-based, and VLAN-based rate limiting policies that can be configured
on ports controlled by the same packet processor also depends on the number of VLANs with byte
accounting enabled on the same packet processor.
On a given packet processor (PPCR), the total of:
Number of VLANs with byte accounting enabled
+
Number of rate limiting policies based on ACLs and VLANs
cannot exceed the maximum number of policies as specified in
Table 67 .
Clearing counters
To clear the byte counter for a VLAN, enter a command such as the following:
BigIron RX(config) #clear vlan byte-accounting 10
You can also enter the following command to clear the byte counter for all VLANs
BigIron RX(config) #clear vlan byte-accounting all-vlans
Syntax: clear vlan byte-accounting <vlan-id> | all-vlans
Enter a VLAN ID if you want to clear the byte counters for a specific VLAN. Enter all-vlans to clear the
byte counters for all VLANs.
Strictly or explicitly tagging a port
If you want a port to be strictly or explicitly tagged, that port has to be removed from the default
VLAN. Enter a command such as the following.
BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# tagged e 1/1 to 1/8
BigIron RX(config-vlan-2)# vlan 1
BigIron RX(config-vlan-1)# no untagged e 1/1 to 1/8
Assigning or changing a VLAN priority
You can prioritize traffic on a VLAN by assigning a priority to a VLAN. All packets associated with the
VLAN will be classified to the configured priority.
BigIron RX(config-vlan-2)# priority 2
Syntax: [no] priority <num>
Possible Values: 0 - 7, "0" assigns the lowest priority and "7", the highest priority. The default is "0".
