arp进程已经为arp表建立了192.168.58.15的项，但是没有对应值，也就是说，192.168.58.15没有对arp广播进行回应，再简单一点，就是192.168.58.15不通。0代表无效，incomplete代表mac为空
是前面那个IP接入交换机的时间，即Age，单位为分钟（min）
先使用show mac-add f0/1,将f0/1下的MAC地址显示出来,并将MAC地址复制到记事本,然后再使用show arp | in xxxx.xxxx.xxxx | xxxx.xxxx.xxxx|...(MAC地址),就可以将该接口下的IP地址都显示出来了。
Theshowiparpcommand, introduced in Cisco IOS Release 9.0, allows you to display only certain ARP table entries based on specified criteria (IP address, interface, or hardware address). However, that command does not display the ARP entry modes, Cisco Express Forwar...
(ARP). Because most hosts support dynamic address resolution, defining static ARP cache entries is usually not required. Performing this task installs a permanent entry in the ARP cache that never times out. The entries remain in the ARP table until they are removed using theno ar...
没有的
在防火场上没有的，从 Tools -> Command line Interface 中，使用 show arp 去显示 ip addresses 和 mac addresses。如下是5505实例：Jswasa5505# sh arp inside 10.61.96.4 00a0.d1e0.6e96 1 inside 10.61.96.47 0025.86a6.f73f 46 inside 10.61.96.10 000f.e2b5.a600 135 insid...
First let us clarify the meaning of the incomplete entries in the arp table. When the IOS device attempts to access some IP address that should be locally connected then it will generate an arp request for that address and will place an entry into the arp table for that address. Since we...
switch#show ip verify source //查IP源防护过滤器状态 动态ARP检测 DAI是一种与DHCP监听和IP源防护相结合的安全特性,DAI需要使用DHCP监听绑定表和配置的静态IP源防护绑定表(使 用ip source binding 命令),所以在配置DAI前交换机必须启用DHCP监听,另外目前只有三层交换机才支持DAI ...
