Table 1. QoS Rules IP Classifier Element tab parameters
Variable | Value
--- | ---
Id | Specifies the number of the IP classifier element.
Name | Specifies the IP classifier element name.
AddressType | Specifies the type of IP address used by this classifier entry. The type is limited to IPv4 and IPv6 addresses.
DstAddr | Specifies the IP address to match against the destination IP address of packet.
DstMaskLength | Specifies the length of the destination address mask.
SrcAddr | Specifies the IP address to match against the source IP address of packet.
SrcMasklength | Specifies the length of the source address mask.
Dscp | Specifies the value for the DSCP in a packet.
Protocol/NextHeader | Specifies the IP protocol value.
DstL4Port | Specifies the value for the Layer 4 destination port number in a packet.
SrcL4Port | Specifies the value for the Layer 4 source port number in a packet.
