随笔...

1.
交换机的东西我一点不懂

今晚学了一点.

100M 电信带宽, 50M 网通带宽

需求:
用 acl 将两种流量区分来做 qos
在光纤口自己限制住 100M + 50M
入的方向有X台机器, 希望带宽可以按应用定优先级, 然后在出的接口控制流量

解决方案:
在入的方向配acl
local-precedence是本地优先级
如果有多条acl区分不同的流，就要配多条traffic-priority命令

出方向配traffic-shape 500000 12 ,
traffic-shape ?
INTEGER<20-1000000> Maximal transmit rate (Kbps).
queue Queue

入方向配qos-acl
之所以在出口限速，
因为ISP提供带宽比交换机端口线速要小

qos-acl是这样用的：
interface GigabitEthernet2/1/2 port access vlan 10 traffic-priority inbound ip-group 3000 rule 0 system-index 3 remark-policed-service untrusted dscp 0 cos 0 local-precedence 1 drop-priority 1

local-precedence是本地优先级
如果有多条acl区分不同的流，就要配多条traffic-priority命令

配了traffice-priority来把不同流标记为不同优先级之后，不同优先级的包就进不同的队列了

比如从千兆端口出去的时候，你只有50m的ISP带宽，就要限一下速度，因为交换机以为你有1000m的总带宽
