S7500E DHCP异常

共4个问题 （1）2个问题 为什么pool 210没有可用IP了？如何解决？ 通过我给的配置可以看到，除开“已用IP、冲突IP”，10.20.210.xxx/24 网段是还有可以IP的，但是在核心交换机 disp dhcp server free-ip pool 210 的结果就是没有，直接空一行。 注：通过后面的查看配置可知：总共可分配 244个，禁用了11个，已用：67，冲突46个，无论如何都应该还有IP地址可以分配的。 （2）2个问题 为什么很多网段地址池的”ip-mac对“的mac前面都有01。这个01是什么意思？虽然都是自动获取IP，但为什么有的mac前就有01，有的就没有呢？如果有h3c文档，请用文档说明。 display dhcp server ip-in-use pool 210 10.20.210.158 0198-9e63-30c2-f0 May 22 16:05:00 2024 Auto(C) # mac 前有01 10.20.210.160 a439-b368-b69b May 22 16:07:11 2024 Auto(C) # mac 前没有01

组网 和 现在核心交换机S7500E 的配置如下 1、组网描述 我有一个h3c交换机搭建的局域网。 核心交换机是：S7500E。接入交换机是：S5130S-52S-EI。 应用地点：学校。发生问题的VLAN：210，在windows计算机教室。 核心交换机作是所有vlan的DHCP服务器；所有区域的VALN都在核心交换机上有 VLAN interface，且他还是是这些VLAN的网关；每个VLAN大致容纳250台左右终端。 2、核心交换机的 210地址池 # 禁止了11个地址的分配 dhcp server forbidden-ip 10.20.210.25 10.20.210.30 dhcp server forbidden-ip 10.20.210.250 10.20.210.254 dhcp server ip-pool
