这个问题提过一次,但是没解决,只好再提出来
新采购了一台S1848G交换机,用于替换老化坏掉的48口dlink交换机,划分了vlan 19(照原先被替下的交换机修改),1~46口均为 vlan 19的成员,47、48为trunk,目前通过48口连接到上一级交换机的网关地址,192.168.19.1,测试1~46口设置为192.168.19.XXX的IP均可以上网使用,但无法远程管理该交换机。尝试将management vlan从1改为19,然后设置IP为192.168.19.254,在47口可以连接到192.168.19.254,但无法连接到网关19.1(包括无法ping,arp无法获取到mac地址,无法用http、telnet等连接到外网),在1~46口依然无法连接到19.254,但可以连接到网关19.1……从管理界面里可以看到外联的来自其他vlan的设备mac地址,但交换机本身无法被访问到,请问这种情况该如何做才能实现远程管理 .
有人提示我应该设立vlan虚接口解决,但是尝试了一下发现,如果想要创建新的虚接口vlan19,就必须删掉旧的虚接口(文档也说过这台设备只支持一个虚接口),而旧的虚接口就是我用来连接这台交换机管理后台的接口,如果我不删除这个旧的接口就没法建立新的接口,可是我删了这个旧的接口怎么操作创建新的虚接口呢?CLI下并没有提供创建虚接口的命令工具,也就是说我用console线连入也没法操作这个,我尝试了如果不删除掉现在正在用于配置交换机的vlan1,则创建新的vlan虚接口时会报错“超过vlan最大数”,这该怎么解决呢?还是先谢谢各位的帮助。

说实话,management 那个没看懂,你改成同一个网段的,跟.1不通,看下是不是绑定了vpn实例啥的

我可以通过web下载cfg文件,notepad打开发给你看下配置。应该是不存在特殊配置的。 # version 5.20.99, Release 1105 # sysname H3C # domain default enable system # ipv6 # telnet server enable # password-recovery enable # vlan 1 # vlan 13 # vlan 19 # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher $********************* authorization-attribute level 3 service-type telnet service-type web # interface NULL0 # interface Vlan-interface1 ip address 192.168.0.233 255.255.255.0 # interface GigabitEthernet1/0/1 port access vlan 19 # interface GigabitEthernet1/0/2 port access vlan 19 # interface GigabitEthernet1/0/3 port access vlan 19 # interface GigabitEthernet1/0/4 port access vlan 19 # interface GigabitEthernet1/0/5 port access vlan 19 # interface GigabitEthernet1/0/6 port access vlan 19 # interface GigabitEthernet1/0/7 port access vlan 19 # interface GigabitEthernet1/0/8 port access vlan 19 # interface GigabitEthernet1/0/9 port access vlan 19 # interface GigabitEthernet1/0/10 port access vlan 19 # interface GigabitEthernet1/0/11 port access vlan 19 # interface GigabitEthernet1/0/12 port access vlan 19 # interface GigabitEthernet1/0/13 port access vlan 19 # interface GigabitEthernet1/0/14 port access vlan 19 # interface GigabitEthernet1/0/15 port access vlan 19 # interface GigabitEthernet1/0/16 port access vlan 19 # interface GigabitEthernet1/0/17 port access vlan 19 # interface GigabitEthernet1/0/18 port access vlan 19 # interface GigabitEthernet1/0/19 port access vlan 19 # interface GigabitEthernet1/0/20 port access vlan 19 # interface GigabitEthernet1/0/21 port access vlan 19 # interface GigabitEthernet1/0/22 port access vlan 19 # interface GigabitEthernet1/0/23 port access vlan 19 # interface GigabitEthernet1/0/24 port access vlan 19 # interface GigabitEthernet1/0/25 port access vlan 19 # interface GigabitEthernet1/0/26 port access vlan 19 # interface GigabitEthernet1/0/27 port access vlan 19 # interface GigabitEthernet1/0/28 port access vlan 19 # interface GigabitEthernet1/0/29 port access vlan 19 # interface GigabitEthernet1/0/30 port access vlan 19 # interface GigabitEthernet1/0/31 port access vlan 19 # interface GigabitEthernet1/0/32 port access vlan 19 # interface GigabitEthernet1/0/33 port access vlan 19 # interface GigabitEthernet1/0/34 port access vlan 19 # interface GigabitEthernet1/0/35 port access vlan 19 # interface GigabitEthernet1/0/36 port access vlan 19 # interface GigabitEthernet1/0/37 port access vlan 19 # interface GigabitEthernet1/0/38 port access vlan 19 # interface GigabitEthernet1/0/39 port access vlan 19 # interface GigabitEthernet1/0/40 port access vlan 19 # interface GigabitEthernet1/0/41 port access vlan 19 # interface GigabitEthernet1/0/42 port access vlan 19 # interface GigabitEthernet1/0/43 port access vlan 19 # interface GigabitEthernet1/0/44 port access vlan 19 # interface GigabitEthernet1/0/45 port access vlan 19 # interface GigabitEthernet1/0/46 port access vlan 19 # interface GigabitEthernet1/0/47 port link-type trunk port trunk permit vlan 1 to 999 # interface GigabitEthernet1/0/48 port link-type trunk port trunk permit vlan 1 to 999 # undo info-center logfile enable # load xml-configuration # user-interface aux 0 user-interface vty 0 15 authentication-mode scheme # return
我拿笔记本直接连在47口(1~46属于vlan19,47、48属于trunk),连接默认地址192.168.0.233对交换机进行管理(48口连上级交换机19.1),但无法连接到19.1以及外部网络。我尝试将management vlan(我的理解这个就是管理用的vlan)从vlan1改为vlan19,然后给设置IP为192.168.19.254,启用后发现,1~46口上网依然正常,能连接到上级交换机192.168.19.1,但无法ping到192.168.19.254也无法连接到管理页面。从47口依然可以ping和连接到192.168.19.254进行交换机管理,但无法上网(ping不到也连接不到上级网关192.168.19.1)。然后就导致我试图通过远程管理这个交换机的尝试失败了。 我搞的都是最基本的设置,没有尝试过搞其他的东西,你说的vpn实体什么的,应该没有弄过。 谢谢指教!多多交流!
我的理解这个管理vlan是不是绑定了什么参数,你看名称管理vlan。console进去看下49口和前面的正常的口的配置是不是多了什么
首先,这款机型的CLI模式(通过console进入)没有提供太多命令,无法查看基本配置,必须通过web配置的。而web配置必须有IP地址。
