所以我想我知道如何在我的 3550 交换机上设置我的 DHCP 服务器并为客户端保留 IP。
我进入了需要保留 IP 的池，但我没有像过去在 IOS 上那样使用地址命令作为选项来执行此操作。

这是 DHCP 池配置
ip dhcp pool data
network 192.168.5.0 255.255.255.0
default-router 192.168.5.1
dns-server xxx.xxx.xxx.x xxx.xxx.xxx.x
lease 8
当我进入 dhcp 池配置时，我确实有以下可用：
xxx3550(config)#ip dhcp pool data
xxx3550(dhcp-config)#?
DHCP pool configuration commands:
bootfile Boot file name
client-identifier Client identifier
client-name Client name
default-router Default routers
dns-server DNS servers
domain-name Domain name
exit Exit from DHCP pool configuration mode
hardware-address Client hardware address
host Client IP address and mask
import Programatically importing DHCP option parameters
lease Address lease time
netbios-name-server NetBIOS (WINS) name servers
netbios-node-type NetBIOS node type
network Network number and mask
next-server Next server in boot process
no Negate a command or set its defaults
option Raw DHCP options
xxx3550(dhcp-config)#
我只需要为特定的 MAC 地址保留一个 IP 地址。我通常会
Address xxx.xxx.xxx.xx Hardware-Address AABB.CC00.11FF
