DHCP+三層交換機？？

wjlxsl

一臺銳捷3550-24GE三層交換機
劃了三個VLAN
VLAN1的IP為：192.168.1.111/24
VLAN2的IP為：192.168.20.1/24
VLAN3的IP為：192.168.30.1/24
現(xiàn)在想用DHCP來分配各子網(wǎng)所對應的IP地址。
下面是三層的配置文件：


Switch#sh run

end

Switch#

一臺LINUX做的DHCP服務器。單網(wǎng)卡eth0:192.168.1.214/24
/etc/dhcpd.conf的內容如下：

ddns-update-style interim;
ignore client-updates;
option nis-domain "domain.org";
option domain-name "domain.org";
option domain-name-servers 202.102.15.162;
option time-offset -18000;
default-lease-time 21600;
max-lease-time 43200;


subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
range dynamic-bootp 192.168.1.2 192.168.1.200;
}


subnet 192.168.20.0 netmask 255.255.255.0 {
#server-identifier 192.168.20.1;
option routers 192.168.20.1;
option broadcast-address 192.168.20.255;
range dynamic-bootp 192.168.20.2 192.168.20.200;
}

把DHCP的網(wǎng)線接到三層的E0/24
把測試機器接到VLAN1的任何端口都可以從DHCP服務器獲取到地址。

問題：把測試機器接到VLAN2的相關端口。不能從DHCP服務器獲取地址。
下面是DHCP的日志。不知道是什么原因？？？？

？？？
請各位幫忙看一下！謝謝�。。�

一臺銳捷3550-24GE三層交換機劃了三個VLAN  ,怎么能把VLAN1也算在里面呢
交換機剛買來的時候 所以端口就屬于VLAN1.劃分的時候VLAN1是不算在里面的

er_shi

我做過華為3526用winodws做dhcp的

wolfandy000

在每個VLAN ip地址后面都加:
ip helper-address 192.168.1.214

頂一下!
還沒有找到解決的辦法.
