RFC 791中将IP报文头中的ToS域的最高3位称为Precedence字段,标识8个IP优先级,从高到低顺序取值为7、6、5、4、3、2、1和0。 RFC 791定义的ToS域中,除了Precedence字段外,ToS域中还包括D、T、R三个比特,分别表示延迟要求、吞吐量和可靠性。 RFC 1349重新定义了ToS域,增加了C比特,表示传输开销。 RFC 247...
The following table shows the commonly used code points, as well as their mapping to the legacy Precedence and ToS settings. DSCP Marking: Commonly Used Code Points DSCP DSCP Description Legacy IP Precedence Legacy IP ToS (D, T, R)
If no mapping from DSCP priorities to ToS values is specified, the device uses the default mappings of the system. If you do not specify the parameter dscp-value when running the undo ip-dscp-inbound command, all mappings from DSCP priorities to ToS values is restored. Example # In Diff...
概念DSCP:Differentiated Services Code Point,差分服务代码点。解释IETF于1998年12月发布了Diff-Serv(Differentiated Service)的QoS分类标准,它在每个数据包IP头部的服务类别TOS(Type Of Service)标识字节中,利用已使用的6比特和未使用的2比特字节,通过编码值来区分优先级。Diff-Serv体系规定每一个 ...
The standard mapping between the classes above to the corresponding Layer 2 and 3 settings are as follows: PJLIB Traffic Type IP DSCP WMM 802.1p BEST_EFFORT 0x00 BE (Bulk Effort) 0 BACKGROUND 0x08 BK (Bulk) 2 VIDEO 0x28 VI (Video) 5 VOICE 0x30 VO (Voice) 6 CONTROL 0x38 VO (...
The priority-map downstream dscp command configures mapping from the DSCP priority of 802.3 packets to the user priority of 802.11 packets when packets are sent to an AP from upper-layer devices. The undo priority-map downstream dscp command restores the default mapping from the DSCP priority o...

The ToS bits were originally used for Precedence and ToS (delay, throughput, reliability, and cost) settings, but were later repurposed by RFC2474 for the more versatile DSCP settings.The following table shows the commonly used code points, as well as their mapping to the legacy Precedence ...
