11.2 Classification
Classification consists of adding the following items:
• Add IP or L2 or both classifier elements
• Add a classifier. As mentioned above in the overview section, a classifier can be made up
of one of the following items:
o One IP classifier element
o One L2 classifier element
o One IP and one L2 classifier element
• Optional: Create Classifier Block where a block contains two or more classifier elements.
Please see restrictions below.
When adding a new policy, either a classifier or a classifier block can be assigned to the policy.
Since there is a limit of 15 classification masks available per port, it is advantageous to use
Classifier Blocks whenever possible. Multiple Classifiers can be added to a Classifier Block
allowing up to 15 Classifiers and/or Classifier Blocks per port. By using Classifier blocks, up to a
total of 114 classifiers can be applied to a port.
a) Adding IP and L2 Element
IP Element
To add an IP element, enter the following command:
• ERS5500-48T(config)#qos ip-element <1-64000>?
addr-type Specify the address type (IPv4, IPv6) classifier criteria
ds-field Specify the DSCP classifier criteria
dst-ip Specify the destination IP classifier criteria
dst-port-min Specify the L4 destination port minimum value classifier
criteria
flow-id Specify the IPv6 flow identifier classifier criteria
next-header Specify the IPv6 next header classifier criteria
protocol Specify the IPv4 protocol classifier criteria
src-ip Specify the source IP classifier criteria
src-port-min Specify the L4 source port minimum value classifier criteria
<cr>
Example:
• ERS5500-48T(config)#qos ip-element 1 src-ip 10.62.32.0/19 dst-ip 10.13.196.0/22
L2 Element
• ERS5500-48T(config)#qos l2-element <1-64000>
dst-mac Specify the destination MAC classifier criteria
dst-mac-mask Specify the destination MAC mask classifier criteria
ethertype Specify the ethertype classifier criteria
priority Specify the user priority classifier criteria
src-mac Specify the source MAC classifier criteria
src-mac-mask Specify the source MAC mask classifier criteria
vlan-min Specify the Vlan ID minimum value classifier criteria
vlan-tag Specify the vlan tag classifier criteria
<cr>
Example:
• ERS5500-48T(config)# qos l2-element 1 src-mac 00-00-0A-00-00-00 src-mac-mask
FF-FF-FF-FF-FF-00 ethertype 0x800
