交换机有大量的这种日志,会是什么问题?

最佳答案
日志内容 | DHCP server received a DHCP client’s request packet on interface [STRING], and extended lease from [STRING] pool for the DHCP client (IP [IPADDR], MAC [MAC]). |
参数解释 | $1: IPv4 DHCP服务器所在接口的接口名 $2: IPv4 DHCP服务器地址池名 $3: 分配给IPv4 DHCP客户端的IPv4地址 $4: IPv4 DHCP客户端的MAC地址 |
日志等级 | 5 |
举例 | DHCPS/5/DHCPS_EXTEND_IP: DHCP server received a DHCP client’s request packet on interface Ethernet0/2, and extended lease from p1 pool for the DHCP client (IP 1.0.0.91, MAC 0000-0000-905a). |
日志说明 | IPv4 DHCP服务器为IPv4 DHCP客户端续约 |
处理建议 | 无 |

这些都是同一客户端的信息,但我设置的是永久租期,为什么还是这么频繁的续约?

按照我的理解,虽然你设置的永久,但是这个是客户端的活动探测,离线了之后可以把地址给其它客户端
