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 62 .
.
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".
