我的voip设备接在一口走vlan 2,始终不能从DHCP主机得到ip.下面是配置文件:\r\n\r\nUsing 1344 out of 32768 bytes\r\n!\r\nversion 12.0\r\nno service pad\r\nservice timestamps debug uptime\r\nservice timestamps log uptime\r\nno service password-encryption\r\n!\r\nhostname SGZVOICE21\r\n!\r\nenable secret 5 $1$u2ga$RyDImBjLUdwgxs3iNuxqQ1\r\n!\r\n!\r\n!\r\n!\r\n!\r\n!\r\nip subnet-zero\r\n!\r\n!\r\n!\r\ninterface FastEthernet0/1\r\n switchport access vlan 2\r\n!\r\ninterface FastEthernet0/2\r\n!\r\ninterface FastEthernet0/3\r\n!\r\ninterface FastEthernet0/4\r\n!\r\ninterface FastEthernet0/5\r\n!\r\ninterface FastEthernet0/6\r\n!\r\ninterface FastEthernet0/7\r\n!\r\ninterface FastEthernet0/8\r\n!\r\ninterface FastEthernet0/9\r\n!\r\ninterface FastEthernet0/10\r\n!\r\ninterface FastEthernet0/11\r\n!\r\ninterface FastEthernet0/12\r\n!\r\ninterface FastEthernet0/13\r\n!\r\ninterface FastEthernet0/14\r\n!\r\ninterface FastEthernet0/15\r\n!\r\ninterface FastEthernet0/16\r\n!\r\ninterface FastEthernet0/17\r\n!\r\ninterface FastEthernet0/18\r\n!\r\ninterface FastEthernet0/19\r\n!\r\ninterface FastEthernet0/20\r\n!\r\ninterface FastEthernet0/21\r\n!\r\ninterface FastEthernet0/22\r\n!\r\ninterface FastEthernet0/23\r\n!\r\ninterface FastEthernet0/24\r\n switchport trunk encapsulation dot1q\r\n switchport mode trunk\r\n!\r\ninterface VLAN1\r\n ip address 192.168.107.121 255.255.255.0\r\n no ip directed-broadcast\r\n no ip route-cache\r\n!\r\ninterface VLAN2\r\n ip directed-broadcast\r\n no ip route-cache\r\n shutdown\r\n!\r\nip default-gateway 192.168.107.213\r\n!\r\nline con 0\r\n transport input none\r\n stopbits 1\r\nline vty 0 4\r\n password password\r\n login\r\nline vty 5 15\r\n password password\r\n login\r\n!\r\nend\r\n\r\n\r\n为什么vlan 2总是shutdown,我用no shutdown也改不过来,如何改?\r\n谢谢.

这里的VLAN2是在29XX上创建的，还是从别的VTP SERVER学来的？

g00g

楼上的,对不起,我不太明白你的意思?\"从别的vtp server学来的是什么意思?\r\n我在2900上肯定已经创建了vlan2.\r\n\r\n另外请问:如何是2900恢复到最初状态?就是和新买来的一样?\r\n\r\n请各位帮帮忙,我被困异乡,解决不了回不了家呀!!!!555!!!!

兄弟，你到http://forums.ultratechnology.net/forumdisplay.php?s=&forumid=33这里问问或许可以解决

但是这里就没人能帮我一下吗?

我只懂一点，用一WINDOWSPC连接2900控制口，用TELNET进入2900，然后就试试看吧！

我问那些的意思是，29XX（XL系列）上创建VLAN不应该是你用的命令，你的配置让我以为VLAN2是从别的VTP SERVRE上学来的，这台29是VTP CLIENT.\r\n至于什么是VTP SERVER，什么是VTP CLIENT，说来话长。\r\n具体的在29上配置VLAN，请参阅：\r\nhttp://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc6/scg/swvlan.htm#xtocid35\r\n恢复出场配置的方法：\r\nhttp://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc6/scg/swtrbl.htm#xtocid16
