SPA-2X1GE-V2 Hw 1.0 QoS配置后不生效

SIP-400版本为15.3(3)S4

[546209412]

show policy-map interface x/x/x  显示30 second offered rate 0000 bps, drop rate 0000 bps

具体业务感知也是，没有起到对应QoS作用

可以说一下具体的配置，需要做的内容是什么？如果只提供板卡型号和版本的话，基本上无法判断问题所在。

首先还是要确认配置是否正确，接下来配置的内容是否命中相关流量，如果有流量命中，再按照Policy来进行才是预期的行为。

BTW，关于这个问题，好在有一定的说明，7600安装SIP400可以参考下如下描述：

The Cisco 7600 SIP-400 does not support the following QoS classification features with AToM:

–Matching on data-link connection identifier (DLCI) is unsupported

–Matching on virtual LAN (VLAN) is unsupported

–Matching on class of service (CoS) is unsupported in Cisco IOS Release 12.2(18)SXE and Cisco IOS Release 12.2(18)SXE2 only. Beginning in Cisco IOS Release 12.2(18)SXF, it is supported with the 2-Port Gigabit Ethernet SPA.

–Matching on input interface is unsupported

–Matching on packet length is unsupported

–Matching on media access control (MAC) address is unsupported

–Matching on protocol type, including Border Gateway Protocol (BGP), is unsupported

一个正常的CBWFQ配置，76上其他卡配置的CBWFQ是生效的，另一张SPA-2X1GE-V2  Hw 版本是1.2, cbwfq配置后是生效的

目前hw为1.0的SPA-2X1GE-V2 接口配置完qos后不生效，即 整个qos配置，没有流量匹配，相当于接口出向没配置qos

Main Specification of 10/100/1000Base Adapter

The Cisco SPA-2X1GE-V2 Dual-Ports 100 MBPS Fast Ethernet Adapter is a network interface card (NIC) that provides two 100 Mbps fast Ethernet ports. It is designed to be used with Cisco's Service Provider Access (SPA) platform, which is a series of modular interface cards that can be used to upgrade or expand the capabilities of Cisco routers and switches.

The product is a compact, low-power device that can be used to connect two devices to a network at speeds of up to 100 Mbps. It supports full-duplex operation, which means that data can be transmitted and received simultaneously. The NIC also supports Quality of Service (QoS) features, which allow network administrators to prioritize traffic and ensure that critical applications receive the bandwidth they need.

The module is also compliant with IEEE 802.3u and IEEE 802.3z standards, which are the standards for fast Ethernet and Gigabit Ethernet, respectively. This means that the NIC is compatible with a wide range of network devices and protocols.

Quality components of 2 Port Network Adapter

The Cisco SPA-2X1GE-V2 Dual-Ports 100 MBPS Fast Ethernet Adapter is a high-quality networking device that includes several key components that contribute to its performance and reliability. These components include:

• Dual Gigabit Ethernet ports: The adapter includes two Gigabit Ethernet ports, providing a high-speed connection to other network devices.
• 100 Mbps Fast Ethernet: The adapter supports a maximum data transfer rate of 100 Mbps, providing fast and reliable connectivity.
• Quality of Service (QoS): The adapter includes QoS features that allow for the prioritization of different types of network traffic, ensuring that critical applications have the bandwidth they need.
• Auto-negotiation: The adapter automatically detects and configures the best possible speed and duplex settings for each connected device, ensuring optimal performance.
• Error Correction: The adapter includes error correction capabilities that help to ensure data integrity and reduce the risk of errors.
• Security: The adapter includes security features such as access control lists (ACLs) and port security, helping to protect the network from unauthorized access and attacks.
• Compatibility: The adapter is compatible with a wide range of Cisco networking devices and platforms, making it easy to integrate into existing networks.

目前没有看到关于SPA-2X1GE-V2不支持QoS的内容。另外一张SPA卡也是在同一设备上吗？

[546209412]

是的，同一台76 ，同一个sip-400槽位的，两张SPA卡，一张可以，一张不行

[546209412]

是的，同一台76 ，同一个sip-400槽位的，两张SPA卡，一张可以，一张不行，区别就是另一张SPA卡 hw 版本显示1.2，有问题的这张显示1.0

不知道是不是设备的资源不足了？现在设备配置的Feature多吗？如下命令可以尝试看看是否有用

show mls qos interface gx/x/x

show mls qos queuing interface

show mls qos

show mls qos aggregate-policer
