zxAnQosTrafficPrfTable entry. The multi-variables binding rule should be complied with when a manager creates an entry. According to this rule, all the related mib variables must be included in one SNMP set operation. There are two types of variables: mandatory and optional. All of the mandatory variables must be included in one SNMP set operation. Optional variables may be included in one SNMP set operation with the mandatory variables, but must not be used alone. To create an entry, the mandatory and optional variables are as follows: mandatory: zxAnQosTrafficPrfCir, zxAnQosTrafficPrfCbs, zxAnQosTrafficPrfPir, zxAnQosTrafficPrfPbs, zxAnQosTrafficPrfDiscardMode, zxAnQosTrafficPrfColorMode, zxAnQosTrafficPrfPolicerType, zxAnQosTrafficPrfCouplingEn, zxAnQosTrafficPrfRowStatus. optional : none. To delete an entry, only zxAnQosTrafficPrfRowStatus is needed in one SNMP setOperation. After an entry is created, variables zxAnQosTrafficPrfCir, zxAnQosTrafficPrfCbs, zxAnQosTrafficPrfPir, zxAnQosTrafficPrfPbs, zxAnQosTrafficPrfDiscardMode, zxAnQosTrafficPrfColorMode, zxAnQosTrafficPrfPolicerType and zxAnQosTrafficPrfCouplingEn can be modified alone. Make sure that zxAnQosTrafficPrfPir is not less than zxAnQosTrafficPrfCir, and zxAnQosTrafficPrfPbs is not less than zxAnQosTrafficPrfCbs when to create or modify an entry.
