3。Cat4000/6500 with CatOS
set span命令
cat4k#set span 1/2 1/3
//把1/2得流量镜像到1/3
4。Cat4500/6500 with IOS
同2--Cat2950/3550/3750
方法四:VACL
VACL=VLAN ACL=Security ACL
只能在Cat6500上使用
CatOS:
c6509 (enable) set security acl ip MyCap permit tcp any any eq 443
c6509 (enable) set security acl ip MyCap permit tcp any eq 443 any
c6509 (enable) set security acl ip MyCap permit ip any any capture
//排除所有访问443端口的流量,其他流量都是感兴趣的
c6509 (enable) commit security acl MyCap
//定义一个security ACL的name
c6509 (enable) set security acl map MyCap 100,101
//把security ACL应用到vlan 100和101上
c6509 (enable) set security acl capture-ports 3/1
//把capture的流量镜像到3/1端口上
IOS:
c6509(config)# access-list 100 permit ip any any
c6509(config)# vlan access-map MyCap 10
c6509(config-access-map)# match ip address 100
c6509(config-access-map)# action forward capture
c6509(config)# vlan filter MyCap vlan-list 200 , 201
c6509(config)# interface gi3/1
c6509(config-if)# switchport capture
