私有vlan配置-连接问题

Question

我和二等兵Vlans有个问题。我有光纤调制解调器，它们无法达到DHCP/TFTP的要求。我从私有VLAN的配置中怀疑。你能复习一下吗？我主要怀疑的是访问交换机和千兆位端口上的主干配置。

简而言之，调制解调器在打开电源时，试图通过DHCP获得IP，发送无标记帧到接入交换机4506，并且应该在vlan 11上处理，因为它们是无标记的专用vlan。在广播发现后，DHCP应该通过vlan 10转到聚合器交换机。在聚合器交换机4500 x上，有一个带有ip辅助地址的SVI vlan 10，提供服务器的地址是向他发送单播数据包。

访问交换机4506上的配置：

vlan 10
name vlan_10
 private-vlan primary
!
vlan 20
name vlan_20
 private-vlan primary
!
vlan 30
name vlan_30
 private-vlan primary
!
! Isolated VLAN: Connects all CPE hosts to Switch 
!
vlan 11
name Pvlan_11
 private-vlan isolated
!
vlan 21
name Pvlan_21
 private-vlan isolated
!
vlan 31
name Pvlan_31
 private-vlan isolated
!
!  Associating
!
vlan 10
 private-vlan assoc 11
!
vlan 20
 private-vlan assoc 21
!
vlan 30
 private-vlan assoc 31
!
! Isolated port (Can only communicate with Primary port)
!
interface giX/Y
switchport mode private-vlan trunk promiscuous
switchport private-vlan trunk native vlan 11
switchport private-vlan trunk allowed vlan 11,21,31
switchport private-vlan mapping trunk 10 11
switchport private-vlan mapping trunk 20 21
switchport private-vlan mapping trunk 30 31

Answer 1

经过几次测试后，我找到了解决方案，而且正在工作。我的第一个配置是不完整的。

这里是一个工作配置：

vlan 10
name vlan_10
 private-vlan primary
!
vlan 20
name vlan_20
 private-vlan primary
