SNMP IFINDEX PERSIST
作者:agou 日期:2012-04-17
在设备升级系统版本等过程中，ifindex可能会变更，导致网管系统对原有接口等的监控失效，ifindex的保持能延续接口的索引，保证监控的延续性。
Your network monitoring application, such as MRTG, is configured to monitor a specific interface. Since there are more than one interface on a device, monitoring will be based on the specific interface's assigned ifIndex.
However, after a hard device reboot, the ifIndex has changed, causing problems with MRTG reporting. This may occur intermittently; sometimes, ifIndex are the same after a reboot, sometimes they change (especially after adding logical interfaces and/or FastEthernet or GigabitEthernet modules).
This has been addressed in RFC2863 (updatint the ifIndex definition under RFC1213). As such, Cisco introduced SNMP ifIndex persistence; simply put, the current ifIndex assigned to the interface will be the permanent.

运行iou报错。. ./start.sh
./wrapper-linux: error while loading shared libraries: libcrypto.so.4: cannot open shared object file: No such file or directory
已经
apt-get -y install libgcrypt11 libgcrypt11-dev
安装完相应的包后执行 :
ln -s /usr/lib32/libcrypto.so.0.9.8 /usr/lib/libcrypto.so.4

Cisco QoS配置说明（CBWFQ/LLQ/PQ/CQ/WFQ）
作者:agou 日期:2012-03-04
QOS-CBWFQ
CBWFQ 基于类别的加权公平排队,通常使用ACL定义数据流类别，并将注入宽带和队列限制等参数应用于这些类别.
CBWFQ特点:
1)能够给不同的类保障一定的带宽
2)对传统的WFQ作了扩展支持用户自己定义流量的分类:
3)队列的个数和类别是一一对应,给每个class 保留带宽
CBWFQ与WFQ的区别：
WFQ: 用户无法控制分类，由HASH算法自己决定
CBWFQ:让用户对流量自己来分类
WFQ 对正常流量 处理没问题，但是对语音流量显得”太公平”(语音要求低延迟)
CBWFQ:考虑到公平特性，并没有考虑到语音的应用
