这类似于OpenFlow控制器以reactive方式对PacketIn作出反应并编辑流表。(3)策略预推送,即所有的应用策略都由APIC预先推送给ACI Leaf/vLeaf,但是策略在设备本地不会立刻进行编译,而是等到EP上线时才会开始编译并生效。(1)的优点是APIC的实时开销几乎为零,缺点是设备上的ACL太多,(2)与(1)相反,优点是设备上不存没有...

The ACL information gets applied to the incoming SIP request. If the ACL does not allow the SIP request, the call fails with a 403 Forbidden message. If the ACL allows the SIP request, Unified Communications Manager checks whether digest authentication is enabled ...
fragmentation is often used in attempts to evade detection by intrusion detection systems. For these reasons, IP fragments are often used in attacks, and so they must be explicitly filtered at the top of any configured iACLs. This example ACL includes comprehensive...

Switches perform lookups in these tables for result information, such as to determine whether a packet with a specific destination IP address is supposed to be dropped according to an ACL. Cisco Catalyst switches deploys these memory tables using specialized memory architectures, referred to as CAM...
OPTIONAL: Configure the template refresh rate. This the number of minutes between sending a template record to our NetFlow collector. The default is 30 minutes and will probably work in most cases. flow-export template timeout-rate 1 Next we create an ACL to flag interesting traffic and apply...
