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 elem ent

o One L2 classifier elem ent

o One IP and one L2 classifier element

• Optional: Create Classifier Block where a block contains two or more clas sifier elements.

Please see restrictions below.

When adding a new policy, either a classifier or a classifier block can be as signed to the policy.

Since there is a limit of 15 classification masks available per por t, it is advantageous to use

Classifier Blocks whenever possible. Multiple Classifiers can be added t o a Classifier Block

allowing up to 15 Classifiers and/or Classifier Blocks per port. By using C lassifier 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
