我正在尝试在我的 5505 上进行流量整形。我可以进行常规监管，但与往常一样，监管结果时好时坏，不会产生最佳结果。
当我尝试创建自己的类映射时，我收到有关 的消息ERROR: 'shape' can only be configured for class "class-default"
，尽管我无法找到通过端口绑定类默认映射的方法。
这是我尝试自己的课程和政策时得到的结果：
ASA(config)# class-map test
ASA(config-cmap)# match port tcp eq 80
ASA(config-cmap)# exit
ASA(config)# policy-map test
ASA(config-pmap)# ?

mpf-policy-map-class mode commands/options:

ASA(config-pmap-c)# shape av
ASA(config-pmap-c)# shape average ?
mpf-policy-map-class mode commands/options:

multiple of 8000
ASA(config-pmap-c)# shape average 64000
ERROR: 'shape' can only be configured for class "class-default"
ASA(config-pmap-c)#
现在，离开 class-default 类，我可以执行以下操作：
ASA(config)# policy-map tester
ASA(config-pmap)# ?
MPF policy-map configuration commands
class Policy criteria
description Specify policy-map description
exit Exit from MPF policy-map configuration mode

set Set connection values

user-statistics configure user statistics for identity firewall
<cr>
csc Content Security and Control service module
flow-export Configure filters for NetFlow events

正如您所看到的，我没有通过端口等进行限制的选项。
有什么想法我可以实现这个目标吗？

简而言之，从当前版本 (ASA 8.4.2) 开始，无法shape对特定流量执行传统 QoS。ASA 只能shape 全部将给定接口上的流量限制为指定的速率。
使用以下ASA QoS 配置指南中的相关部分作为完整的参考。您可能会发现这也很有趣。
