我想使用基于子网范围的类声明,可以吗?还是所有类都是全局范围的?
这是我的 dhcp.conf 片段:
subnet 10.200.147.0 netmask 255.255.255.224 {
authoritative;
option domain-name-servers 10.200.17.28;
option routers 10.200.147.1;
option subnet-mask 255.255.255.224;
class "Cisco AP c1240 22nd fl" {
match if option vendor-class-identifier = "Cisco AP c1240";
option option-043 f1:0c:0a:c8:d3:46:0a:c3:d3:45:0a:c3:d3:47;
option vendor-class-identifier "Cisco AP c1240";
vendor-option-space Cisco_LWAPP_AP;
}
group {
option domain-name "cde.net";
host ap1.aaa{
fixed-address 10.200.147.4;
hardware ethernet 00:aa:bb:cc:dd:ee;
option host-name "ap1.aaa.cde.net";
}
这也是在同一个文件中:
subnet 10.201.147.0 netmask 255.255.255.224 {
authoritative;
option domain-name-servers 10.201.17.28;
option routers 10.201.147.1;
option subnet-mask 255.255.255.224;
class "Cisco AP c1240 1gp" {
match if option vendor-class-identifier = "Cisco AP c1240";
option option-043 f1:08:0a:c2:d2:04:0a:d0:d1:04;
option vendor-class-identifier "Cisco AP c1240";
vendor-option-space Cisco_LWAPP_AP;
}
group {
option domain-name "cde.net";
host ap1.bbb {
fixed-address 10.201.147.4;
hardware ethernet 00:11:22:33:44:55;
option host-name "ap1.bbb.cde.net";
}
我在日志文件中看到了这一点,这让我认为所有类声明都是全局的:
Dec 7 06:22:20 [email protected] dhcpd: too many classes match 00:aa:bb:cc:dd:ee
但是我没有在 isc dhcp 文档中看到任何可以证实我的理论的内容。
答案1
所有类都是全局的(当您使用 测试配置是否存在错误时,您会看到一条警告dhcpd -t -cf dhcpd.conf
。
我不知道这是否重要,因为你option vendor-class-identifier
在课堂上也声明了两次。
