关于Catalyst 6509的笔记  Date:2001.5.3
1.如果在6509的MSFC上新增了一个Vlan接口,如果6509上没有属于该Vlan的端口,或这些端口均没有连接设备(即没有LINK信号),则在MSFC上的Vlan接口也不会处于UP的状态。
2.如果6509的冗余Supervisor与主Supervisor型号有出入,如主引擎为WS-X6K0SUP1A-MSFC,而备份引擎为:WS-X6K0SUP1A-MSFC2(注意msfc2是msfc的改进版,这个产品号可能已经取消),则show modu 时可以看到备引擎的MSFC处于disable或other状态。所以订备份引擎时要小心哦!
3.在测试一台路由器时,我注意到路由器到相邻子网的连接不正确,查看了一下配置,原来是ip subnet-zero 和ip classless没有设置。
如没有ip subnet-zero, 192.168.1.10 (255.255.255.248) ping不通192.168.1.3 (255.255.255.248).
问题1: 6509上某些端口收发出现太多错误,则会被设为禁止(errdisable)状态,原因待查。
问题2:在路由表中可见一条到169.169.71.0/24的ospf路由,但数据包仍使用了0.0.0.0的静态默认路由,即使调高了默认路由Administrative distance.觉得比较奇怪,谁见过类似的情况?
欢迎来信讨论。
