# DELL 网络交换机 基本配置说明 ## 配置账号密码 Dell 默认的用户名和密码都是 admin，如果希望修改或添加新的用户 账号:**admin** 密码:**passwor\_123** ``` OS10# configure terminal OS10(config)# username admin password passwor_123 role sysadmin OS10(config)# end OS10# write memory ``` ## 设置带外管理 ``` OS10# OS10# configure terminal OS10(config)# interface mgmt 1/1/1 OS10(conf-if-ma-1/1/1)# no ip address dhcp OS10(conf-if-ma-1/1/1)# no ipv6 address autoconfig OS10(conf-if-ma-1/1/1)# exit OS10(config)# ip vrf management OS10(conf-vrf)# interface management OS10(conf-vrf)# exit OS10(config)# interface mgmt 1/1/1 OS10(conf-if-ma-1/1/1)# ip address 10.0.0.1/24 OS10(conf-if-ma-1/1/1)# no shutdown OS10(conf-if-ma-1/1/1)# show configuration ! interface mgmt1/1/1 no shutdown no ip address dhcp ip address 10.0.0.1/24 OS10(conf-if-ma-1/1/1)# exit OS10#OS10(config)# management route 0.0.0.0/0 172.16.1.254 (带外网络默认路由) OS10(config)#do write ``` ## 交换机接口配置 ### 设置Accsee模式 例：创建 VLAN10 并将 e1/1/1 接口以 access 模式划入 vlan10. ``` OS10# configure terminal OS10(config)# interface vlan 10 //创建vlan10 OS10(conf-if-vl-10)# exit OS10(config)# interface e1/1/1 OS10(conf-if-eth1/1/1)# switchport mode access //设置为accsee模式 OS10(conf-if-eth1/1/1)# switchport access vlan 10 // 设置为vlan 10通过 OS10(conf-if-eth1/1/1)# no shutdown OS10(conf-if-eth1/1/1)# do write ``` ### Trunk 模式 例：创建 VLAN10 和 20，并将 e1/1/2 接口配置为 trunk 模式且放行 vlan10 和 20. ``` OS10# configure terminal OS10(config)# interface vlan 10 OS10(conf-if-vl-10)# exit OS10(config)# interface vlan 20 OS10(conf-if-vl-20)# exit OS10(config)# interface e1/1/2 OS10(conf-if-eth1/1/2)# switchport mode trunk //设置为trunk模式 OS10(conf-if-eth1/1/2)# switchport trunk allowed vlan 10,20 //允许vlan10 20 通过 OS10(conf-if-eth1/1/2)# show configuration ! interface ethernet1/1/2 no shutdown switchport mode trunk switchport access vlan 1 (如果你希望 默认vlan 为 2，此处请 switch access vlan 2 ) switchport trunk allowed vlan 10,20 OS10(conf-if-eth1/1/2)# do write memory ``` ### 修改默认 VLAN OS10 默认 VLAN 是 1 且默认所有 trunk 口都 untagged vlan1，如果需要修改其他 VLAN 为 默认 VLAN ``` OS10# configure terminal OS10(config)# interface vlan 4093 OS10(conf-if-vl-4093)# exit OS10(config)# default vlan-id 4093 OS10(config)# do show vlan Codes: * - Default VLAN, M - Management VLAN, R - Remote Port Mirroring VLANs Q: A - Access (Untagged), T - Tagged NUM Status Description Q Ports 1 Inactive * 4093 Active A Eth1/1/1-1/1/32 OS10(config)#do write ``` ## 设置链路聚合 ### 静态链路聚合 本例：对 e1/1/49 和 50 接口静态聚合为 PO1，并且配置为 trunk 模式和放行 vlan10,20 ``` OS10# configure terminal OS10(config)# interface port-channel 1 //创建聚合口1 OS10(conf-if-po-1)# switchport mode trunk //设置为trunk模式 OS10(conf-if-po-1)# switchport trunk allowed vlan 10,20 //放行vlan 10,20 OS10(conf-if-po-1)# no shutdown OS10(conf-if-po-1)# exit OS10(config)# interface range e1/1/49-1/1/50 //进入1/1/49-1/1/50接口 OS10(conf-range-eth1/1/49-1/1/50)# channel-group 1 // 加入聚合口1 OS10(conf-range-eth1/1/49-1/1/50)# no shutdown OS10(conf-range-eth1/1/49-1/1/50)# end OS10#write 查看： OS10# show interface port-channel 1 summary ``` ### 动态 LACP 聚合 ``` OS10# configure terminal OS10(config)# interface port-channel 1 OS10(conf-if-po-1)# switchport mode trunk OS10(conf-if-po-1)# switchport trunk allowed vlan 10,20 OS10(conf-if-po-1)# no shutdown OS10(conf-if-po-1)# exit OS10(config)# interface range e1/1/49-1/1/50 OS10(conf-range-eth1/1/49-1/1/50)# channel-group 1 mode active //设置为lacp模式 OS10(conf-range-eth1/1/49-1/1/50)# no shutdown OS10(conf-range-eth1/1/49-1/1/50)# end OOS100#write 查看： OOS100# show interface port-channel 1 summary ``` ## 本地端口镜像 本例中，将 e1/1/1 口的进和出两个方向的流量镜像到 e1/1/2 口进行抓包分析。 ``` OS10(config)# interface e1/1/2 OS10(conf-if-eth1/1/2)# no switchport OS10(conf-if-eth1/1/2)#exit OS10(config)# monitor session 1 //创建本地镜像组 OS10(conf-mon-local-1)# source interface ethernet 1/1/1 both //设置源端口（被监控的） OS10(conf-mon-local-1)# destination interface e1/1/2 //设置目的端口（监控的） OS10(conf-mon-local-1)# no shut ``` ## DHCP Server 配置 本例中，网段为192.168.10.0/24，网关为192.168.10.1，dns为8.8.8.8和9.9.9.9， ``` OS10# configure terminal OS10(config)# ip dhcp server OS10(config-dhcp)# pool 192_168_10 OS10(config-dhcp-192_168_10)# lease 0 6 0 （租期为 6 小时） OS10(config-dhcp-192_168_10)# network 192.168.10.0/24 （此处的/24 前面是没有空格的） OS10(config-dhcp-192_168_10)# default-router 192.168.10.1 （网关地址） OS10(config-dhcp-192_168_10)# dns-server 8.8.8.8 OS10(config-dhcp-192_168_10)# dns-server 9.9.9.9 OS10(config-dhcp-192_168_10)# domain-name dhcp.os10.dell （名称，可选） OS10(config-dhcp-192_168_10)# exit OS10(config-dhcp)# no disable OS10(config-dhcp)# do write 查看地址分配表: OS10#show ip dhcp binding ``` ## 一般命令 #### 保存 ``` OS10# write //保存交换机配置，请在完成必要配置之后，记得使用此命令保存，否则交换机重启后没保存的配置将丢失 ``` #### 修改名称 ``` OS10>en OS10#configure OS10(config)#hostname ABC //将交换机改名为ABC OS10(config)#end OS10#write ``` #### 配置边缘端口 **连接到此交换机的电脑获取DHCP非常慢，或者很慢才能够识别网络，可以考虑配置** ``` OS10#configure OS10(config)#interface gi1/0/1 //如果对多个端口同时配置，可以使用interface range gi1/0/1-12 OS10(config-if)# spanning-tree portfast OS10(config-if)#exit OS10(config)#end OS10#write ``` #### 开启巨帧流控 **连接ISCSI存储时一般建议配置巨帧和流控** ``` OS10>enable OS10#configure OS10(config)#system jumbo mtu 9216 -------------开巨帧 OS10(config)#flowcontrol receive on -------------开流控 OS10(config)#end OS10#write ``` #### 删除配置（重置交换机） ``` OS10>enable OS10#write //保存配置 OS10#delete startup-config //删除启动配置文件 Delete startup-config ? (y/n) y //y 确认删除 OS10# reload //重启交换机 Are you sure you want to reload the stack? (y/n) y //y 确认重启 ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
