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 ds-field dst-ip dst-port-min

flow-id next-header protocol src-ip src-port-min

<cr>

Specify the address type (IPv4, IPv6) classifier criteria Specify the DSCP classifier criteria

Specify the destination IP classifier criteria

Specify the L4 destination port minimum value classifier criteria

Specify the IPv6 flow identifier classifier criteria Specify the IPv6 next header classifier criteria Specify the IPv4 protocol classifier criteria Specify the source IP classifier criteria

Specify the L4 source port minimum value classifier criteria

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 dst-mac-mask ethertype priority src-mac src-mac-mask vlan-min vlan-tag

<cr>

Specify the destination MAC classifier criteria Specify the destination MAC mask classifier criteria Specify the ethertype classifier criteria

Specify the user priority classifier criteria Specify the source MAC classifier criteria Specify the source MAC mask classifier criteria Specify the Vlan ID minimum value classifier criteria Specify the vlan tag classifier criteria

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
