access-list checkbfd-in in access-list checkbfd-out out ! ! ! 在本例中,此ACL使用两个序列。序列10匹配从此vEdge发送到对等设备的BFD消息。序列20的效果与此相反。 它匹配源(Private)端口和目标(Public)端口。如果vEdge使用NAT,请确保检查正确的源和目标端口。
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...
關聯篩選器。可以內聯指定過濾器,也可以引用ACL或類對映。 在本例中,ACL用於匹配9800的兩個IP地址與另一個WLC 5520之間的流量。移動性故障排除的典型場景: conf t ip access-list extended mobilitywlcs permit ip host <5520_ip_address> host <9800_ip_address> permit ip host <9800_ip_...
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...
