Quidway S3952P-SI 不能保存配置的错误解决

Published on 2011-09-06 in 计算机\网络 and 随写. 0 Comments Tags: , , .

一台Quidway S3952P-SI交换机，保存后配置会丢失，交换机直接进入初始化配置。查看启动选项，当前保存的配置为NULL，如下：

[cheshisw] dis startup
UNIT1:
Current Startup saved-configuration file: NULL
Next main startup saved-configuration file: flash:/vrpcfg.cfg
Next backup startup saved-configuration file: NULL
Bootrom-access enable state: enabled

重启交换机，按[crtl]+[B]，会出现如下图的界面。

港湾NetHammer M582路由器启用DHCP

Published on 2010-12-19 in 计算机\网络 and 随写. 0 Comments Tags: , , , .

一台港湾NetHammer M582路由器，原客户端为静态IP方式上网，简要配置如下：

access-list 1 permit any
!
interface eth0/0
description to-lan
ip address 172.16.101.1/24
ip nat inside
!
interface eth0/1
description to-internet
ip address 218.90.xxx.xxx/28
ip nat outside
!
ip route 0.0.0.0/0 218.90.xxx.xxx
!
ip nat on
ip nat flush disable
ip nat inside source list 1 interface eth0/1
!

现在需在内网中增加一新网段172.172.1.0/24，网关为172.172.1.254，客户端可以通过DHCP方式获取地址来上网，同时不影响原静态IP上网的用户，操作如下：

NetHammer582> en
password:
NetHammer582# conf t
NetHammer582(config)# service ip dhcp
NetHammer582(config)# inter eth0/0
NetHammer582(config-if-eth0/0)# ip address 172.172.1.254/24 secondary
NetHammer582(config-if-eth0/0)# quit
NetHammer582(config)# dhcp subnet 172.172.1.0 mask 255.255.255.0
NetHammer582(config-dhcp-subnet)# range 172.172.1.1 172.172.1.150
NetHammer582(config-dhcp-subnet)# option routers 172.172.1.254
NetHammer582(config-dhcp-subnet)# option domain-name-servers 221.228.255.1
NetHammer582(config-dhcp-subnet)# quit
NetHammer582(config)# quit
NetHammer582# wr
Generate running-config…
write running-config to flash…
Write flash success!

摘要配置如下（红色为增加部分）：

access-list 1 permit any
!
service ip dhcp
!
interface eth0/0
description to-lan
ip address 172.16.101.1/24
ip address 172.172.1.254/24 secondary

锐捷交换机光电复用口将光口改为电口

Published on 2008-01-10 in 服务器维护, 计算机\网络 and 随写. 2 Comments Tags: , , , .

锐捷交换机的光电复用口 的转换，前阵子是把光口改成了电口来使用（默认开启的是电口），现在这交换机上有三个口又要改成用当电口来使用，光口改电口是使用med fiber参数来调整，通过med ?参数查看除fiber以外的值，发现只有copper和fiber，很明显电口的值就是copper，如下图：

这样，通过使用med copper参数就可以将光口改为电口了，这里我是修改gig 0/2-4口，步骤如下：

shixunlou5750#conf
Enter configuration commands, one per line. End with CNTL/Z.
shixunlou5750(config)#int range gig 0/2-4
shixunlou5750(config-if-range)#med copper
shixunlou5750(config-if-range)#end
shixunlou5750#wr

Building configuration…

[OK]
