5.6.2.1.2 Adding Protocol ID

a. Navigate to ADVANCED CONFIGURATION > QoS > PIR List. Click Details. The QoS PIR Edit Entry screen

appears.

b. Navigate to Protocol Id Entries tab and then click Add to add a new Protocol entry. The following screen

appears.

3. To prioritize DSCP packets based on IP-Precedence/DSCP value/ToS value,

configure “ToS Mask”.

a. IP Precedence: To prioritize based on only IP precedence, set all the 3 IP

Precedence bits in the ToS Mask parameter to “1” and set rest of the bits in

the ToS Mask parameter to ‘0” (i.e decimal value = 224).

b. DSCP Value: To prioritize based on DSCP value, set all the DSCP bits in the

ToS Mask parameter to “1” and set rest of the bits in the ToS Mask

parameter to ‘0” (i.e decimal value = 252).

c. ToS Value: To prioritize based on entire ToS value then set all the bits in the

ToS Mask parameter to “1” (i.e decimal value = 255).

Ether Priority Rule This parameters is used to enable or disable 802.1p priority rule. Enter the values for the

following to specify 802.1p priority configuration:

Priority Low

Priority High

VLAN Rule This parameters allows to enable or disable VLAN rule. Enter the VLAN ID when the VLAN

rule is enabled.

PPPoE Encapsulation This parameter is used to classify PPPoE traffic.

If you Enable/disable the PPPoE Configuration, it will automatically disable the

Ether Type Rule. User can configure it again by enabling Ether Type Rule.

When PPPoE Encapsulation is enabled, incoming packet will be checked against

Ether value “0x8864” and look for PPPoE Protocol Id value “0x0021”(IP Protocol)

by default. User can modify the PPPoE Protocol Id but all the other classification

rules which are specified in the PIR rule will work only if the PPPoE Protocol Id is

“0021”.

Ether Value is not valid when PPPoE Encapsulation is enabled.

Ether Type Rule This parameters is used to enable or disable Ether Type rule. Enter the values for the

following to specify the Ether Type rule related configuration:

Ether Type

PPPoE Protocol Id

Ether Value

PPPoE Protocol Id is not valid if PPPoE Encapsulation is disabled.

Ether Value is not valid if PPPoE Encapsulation is enabled.
