问题描述：
上次因为施工，把交换机电源关闭了，通电后这台路由器下的电脑无法上网。通过咨询贵公司技术人员，说是配置参数丢失，我刚才把交换机数据下载下来后，看了一下，好像是正常的，麻烦给看看！
组网及组网描述：
单位总共有10台24口交换机和一个汇聚路由器，带防火墙的。网关不在24口交换机上

最佳答案
要贴出来具体配置，路由器到外网是否正常？如果是PPOE拨号看拨号是否正常。下面电脑能否正常拿到地址或者手动配置地址能否ping通网关，如果通能否ping通外网。如果不通需要看看路由器dhcp配置是否正常，路由器接交换的vlan是否放行。

只有这台交换机下的电脑无法上网，其他的都可以上网。在这台交换机下的电脑无法ping通网关。
这台交换机是27号口连的路由器么
应该是，具体的不是很了解。我这有上一任管理员给的原来配置的参数 <HYL-B-01>DIS CU # version 5.20.99, Release 1110 # sysname HYL-B-01 # domain default enable system # ipv6 # telnet server enable # password-recovery enable # vlan 1 # vlan 17 to 18 # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user HYL-B-01 password cipher $c$3$YGiVcw0lDZj1Mg0+nM6ROBC5FFwnSJYWfSQ= authorization-attribute level 3 service-type telnet # stp region-configuration region-name yc instance 1 vlan 1 3 5 7 9 11 13 15 17 19 instance 1 vlan 21 23 25 27 29 31 61 63 65 71 instance 1 vlan 73 75 81 instance 2 vlan 2 4 6 8 10 12 14 16 18 20 instance 2 vlan 22 24 26 28 30 32 40 50 62 64 instance 2 vlan 66 72 74 76 82 120 200 220 active region-configuration # stp timer hello 400 stp timer forward-delay 3000 stp timer max-age 4000 stp bpdu-protection stp enable # interface NULL0 # interface Vlan-interface1 ip address 10.0.1.245 255.255.255.0 # interface GigabitEthernet1/0/1 port access vlan 18 # interface GigabitEthernet1/0/2 port access vlan 18 # interface GigabitEthernet1/0/3 port access vlan 18 # interface GigabitEthernet1/0/4 port access vlan 18 # interface GigabitEthernet1/0/5 port access vlan 18 # interface GigabitEthernet1/0/6 port access vlan 18 # interface GigabitEthernet1/0/7 port access vlan 18 # interface GigabitEthernet1/0/8 port access vlan 18 # interface GigabitEthernet1/0/9 port access vlan 18 # interface GigabitEthernet1/0/10 port access vlan 18 # interface GigabitEthernet1/0/11 port access vlan 18 # interface GigabitEthernet1/0/12 port access vlan 18 # interface GigabitEthernet1/0/13 port access vlan 18 # interface GigabitEthernet1/0/14 port access vlan 18 # interface GigabitEthernet1/0/15 port access vlan 18 # interface GigabitEthernet1/0/16 # interface GigabitEthernet1/0/17 # interface GigabitEthernet1/0/18 port access vlan 17 # interface GigabitEthernet1/0/19 port access vlan 17 # interface GigabitEthernet1/0/20 port access vlan 17 # interface GigabitEthernet1/0/21 port access vlan 17 # interface GigabitEthernet1/0/22 port access vlan 17 # interface GigabitEthernet1/0/23 port access vlan 17 # interface GigabitEthernet1/0/24 port access vlan 17 # interface GigabitEthernet1/0/25 port link-type trunk port trunk permit vlan all # interface GigabitEthernet1/0/26 port link-type trunk port trunk permit vlan all # interface GigabitEthernet1/0/27 port link-type trunk port trunk permit vlan all # interface GigabitEthernet1/0/28 port link-type trunk port trunk permit vlan all # ip route-static 0.0.0.0 0.0.0.0 10.0.1.1 # info-center loghost 10.0.2.4 undo info-center logfile enable # snmp-agent snmp-agent local-engineid 383030303633413236353133314341423334413735384141 snmp-agent community read YJZX snmp-agent community write XXZLS snmp-agent sys-info version all snmp-agent target-host trap address udp-domain 10.0.2.4 params securityname YJZX snmp-agent trap enable default-route snmp-agent trap queue-size 500 snmp-agent trap life 600 # load xml-configuration # user-interface aux 0 user-interface vty 0 3 authentication-mode scheme user privilege level 3 user-interface vty 4 15 # return <HYL-B-01> <HYL-B-01>SA The current configuration will be written to the device.

你说的27号连接路由器指的是这台交换机跟跟路由器连接的光模块插口吗？
是 把那两个接口的配置贴出来的 尤其是路由器上面的
只有这台交换机下的电脑无法上网，其他的交换机下的电脑是可以上网的。路由器上的配置我这无法看到。
要看路由器接这台交换机接口的配置
主要是想了解啥，看我了解不？

看你得配置有点乱，看你接电脑得VLAN是17和18，配置中也有17和18，但是显示是不是有问题，上行口应该是25至28中得一个，配置中开启了STP，先关闭STP测试，然后再开启。VLAN所有得VLAN重新配置一下，多余VLAN去掉。
