華為交換機特性與配置(華為交換機基礎配置)1

華為交換機特性與配置

1 允許telnet(遠程登錄)

允許華為交換機能telnet,設置密碼為Admin@123

telnet server en

#

aaa

authentication-scheme default

authorization-scheme default

accounting-scheme default

domain default

domain default_admin

local-user huawei password cipher Admin@123

local-user huawei privilege level 15

local-user huawei service-type telnet terminal

local-user admin password cipher Admin@123

local-user admin service-type http

#

user-interface con 0

authentication-mode password

set authentication password cipher Admin@123

user-interface vty 0 4

protocol inbound telnet

authentication-mode aaa

user-interface vty 16 20

#

華為S5720S交換機遠程登錄

telnet server enable

aaa

authentication-scheme default

authentication-scheme radius

authentication-mode radius

authorization-scheme default

accounting-scheme default

local-aaa-user password policy administrator

password expire 0

domain default

authentication-scheme radius

radius-server default

domain default_admin

authentication-scheme default

local-user admin password irreversible-cipher Admin@123

local-user admin privilege level 15

local-user admin service-type terminal http

local-user huawei password irreversible-cipher Admin@123

local-user huawei privilege level 15

local-user huawei service-type telnet terminal

user-interface con 0

authentication-mode password

set authentication password cipher Admin@123

user-interface vty 0 4

protocol inbound telnet

authentication-mode aaa

user-interface vty 16 20

2 創建VLAN

為交換機劃分VLAN1001,VLAN1002,

設置vlan1001,接口IP地址為172.16.1.254(即網關地址),子網掩碼為255.255.255.0

将g0/0/1~g0/0/24配置為vlan1001

防止arp***

vlan 1001

interface vlan 1001

ip addr 172.16.1.254 24

arp anti-attack gateway-duplicate enable

arp anti-attack rate-limit enable

arp-miss anti-attack rate-limit enable

port-group group1

group-member g0/0/1 to g0/0/24

port link-type access

port default vlan 1001

loopback-detect enable

arp anti-attack rate-limit enable

arp-miss anti-attack rate-limit enable

quit

批量将多個端口添加到Access

port-group group-member GigabitEthernet0/0/17 to GigabitEthernet0/0/22

port link-type access

port default vlan 2006

quit

3 将多個端口添加到Trunk

将25~44端口劃分為Trunk端口

port-group group2

group-member g0/0/25 to g0/0/44

port link-type trunk

port trunk allow-pass vlan 2 to 4094

loopback-detect enable

quit

# 批量将1~16端口添加到Trunk

port-group group-member GigabitEthernet0/0/1 to GigabitEthernet0/0/16

port link-type trunk

port trunk allow-pass vlan 2 to 4094

quit

4 創建鍊路聚合端口

将45、46創建鍊路聚合1,使用RJ45

将47、48創建鍊路聚合2,使用光纖

clear configuration inte g0/0/45

clear configuration inte g0/0/46

clear configuration inte g0/0/47

clear configuration inte g0/0/48

interface Eth-Trunk1

port link-type trunk

port trunk allow-pass vlan 2 to 4094

mode lacp

interface Eth-Trunk2

port link-type trunk

port trunk allow-pass vlan 2 to 4094

mode lacp

interface GigabitEthernet0/0/45

eth-trunk 1

interface GigabitEthernet0/0/46

eth-trunk 1

interface GigabitEthernet0/0/47

eth-trunk 2

combo-port fiber

interface GigabitEthernet0/0/48

eth-trunk 2

combo-port fiber

【說明】每個端口可能需要執行undo shutdown以激活端口。

5 VLAN端口重新配置為Trunk

原配置如下:

interface GigabitEthernet0/0/17

port link-type access

port default vlan 128

将g0/0/17端口配置為Trunk端口命令

undo port default vlan

undo port link-type

port link-type trunk

port trunk allow-pass vlan all

6 Trunk端口重新配置為VLAN

原配置如下

interface GigabitEthernet0/0/11

port link-type trunk

port trunk allow-pass vlan 2 to 4094

将g0/0/11端口配置為VLAN140命令

undo port trunk allow-pass vlan all

port trunk allow-pass vlan 1

port link-type access

port default vlan 140

7 在交換機上配置DHCP Server

(1)vlan2002的網關地址是172.18.92.254,DHCP地址池中排除172.18.92.200~252、172.18.92.253、DHCP的地址租約是1小時、DNS的地址是172.18.96.1

vlan batch 2001 to 2003

ip pool vlan2002

gateway-list 172.18.92.254

network 172.18.92.0 mask 255.255.255.0

excluded-ip-address 172.18.92.200 172.18.92.253

lease day 0 hour 1 minute 0

dns-list 172.18.96.1

#

interface Vlanif2002

ip address 172.18.92.254 255.255.255.0

dhcp select global

#

9 指定DHCP服務器(在交換機上配置DHCP中繼)

【說明】:在交換機上指定DHCP中繼(DHCP服務器是Windows Server中的DHCP)這是在早期華為或華三交換機上的配置,具體那個型号我記不清了,現在這些配置我基本上已經不用了,隻是在這收集整理一下。

#

dhcp enable

#

dhcp server group dhcpgroup1

dhcp-server 172.30.5.3 0

dhcp-server 172.30.5.15 1

#

interface Vlanif2052

ip address 172.28.52.254 255.255.255.0

dhcp select relay

dhcp relay server-select dhcpgroup1

#

以下是摘錄的華為官方幫助文檔内容

# 在接口下使能DHCP中繼功能。

[SwitchA] dhcp enable //使能DHCP服務,缺省未使能

[SwitchA] interface vlanif 100

[SwitchA-Vlanif100] ip address 10.10.20.1 24

[SwitchA-Vlanif100] dhcp select relay //使能DHCP中繼功能,缺省未使能

[SwitchA-Vlanif100] dhcp relay server-ip 192.168.20.2 //配置DHCP中繼代理的DHCP服務器的IP地址

[SwitchA-Vlanif100] quit

10 配置靜态路由

ip route-static 0.0.0.0 0.0.0.0 172.18.96.253

ip route-static 172.18.0.0 255.255.0.0 172.18.96.251

ip route-static 172.30.30.0 255.255.255.0 172.18.96.250

11 配置SNMP

snmp-agent

snmp-agent local-engineid Admin@123

snmp-agent community write cipher Admin@123

snmp-agent sys-info version all

12 為交換機配置堆疊模式

在本示例中将2台S6720S-26Q-EI-24S的交換機,使用40GB QSFP電纜以“堆疊”方式連接在一起。配置為堆疊模式後,兩台交換機相當于“一台”交換機使用。如下圖所示,這是堆疊電纜以及兩台交換機的連接方式。在本示例中,使用兩條40GB的QSFP電纜将兩台交換機的第1個、第2個40GE交叉連接在一起(交換機1的40GE端口1連接交換機2的40GE端口2,交換機1的40GE端口2連接交換機2的40GE端口1)。

圖 兩台交換機組成堆疊模式

在配置“堆疊”之前,先不要連接40GFB QSFP電纜,另外兩台交換機需要相同配置。首先介紹第1台交換機的配置。

# 配置交換機1的業務口40GE0/0/1、40GE0/0/2為物理成員端口,并加入到相應的邏輯堆疊端口。

<HUAWEI> system-view

[HUAWEI] sysname SwitchA

[SwitchA] interface stack-port 0/1

[SwitchA-stack-port0/1] port interface 40GE0/0/1 enable

[SwitchA-stack-port0/1] quit

[SwitchA] interface stack-port 0/2

[SwitchA-stack-port0/2] port interface 40GE0/0/2 enable

[SwitchA-stack-port0/2] quit

# 配置交換機2的業務口40GE0/0/1、40GE0/0/2為物理成員端口,并加入到相應的邏輯堆疊端口。

<HUAWEI> system-view

[HUAWEI] sysname SwitchB

[SwitchB] interface stack-port 0/1

[SwitchB-stack-port0/1] port interface 40GE0/0/1 enable

[SwitchB-stack-port0/1] quit

[SwitchB] interface stack-port 0/2

[SwitchB-stack-port0/2] port interface 40GE0/0/2 enable

[SwitchB-stack-port0/2] quit

接下來配置堆疊ID和堆疊優先級。堆疊ID缺省值為0,堆疊優先級缺省值為100。

[SwitchA] stack slot 0 priority 200 //修改主交換機的堆疊優先級為200,大于其他成員交換機。堆疊ID采用缺省值0。

[SwitchB] stack slot 0 renumber 1 //堆疊優先級采用缺省值100。修改堆疊ID為1。

最後關閉交換機電源開關,将兩台交換機下電,按照圖1-4所示,使用40GB QSFP電纜連接後再上電。

采用堆疊之後,交換機1的1~24端口用XGigabitEthernet0/0/1~XGigabitEthernet0/0/24代表;交換機2的1~24端口用XGigabitEthernet1/0/1~XGigabitEthernet1/0/24代表;交換機1的2個40GB用40GE0/0/1、40GE0/0/2代表;交換機2的2個40GB用40GE1/0/1、40GE1/0/2代表。

使用dis stack命令查看堆疊狀态,如圖所示。‘13 清除堆疊端口配置

在配置交換機堆疊時,如果錯誤配置了交換機的堆疊端口,需要将端口清除配置,可以采用如下的命令。

例如将交換機的G1/0/25與G1/0/26添加到stack-port 1/1,命令如下:

interface stack-port 1/1

port interface GigabitEthernet1/0/25 enable

port interface GigabitEthernet1/0/26 enable

interface stack-port 1/2

port interface GigabitEthernet1/0/27 enable

port interface GigabitEthernet1/0/28 enable

如果要清除這個配置,需要執行如下的配置:

interface stack-port 1/1

shutdown interface GigabitEthernet1/0/25

shutdown interface GigabitEthernet1/0/26

undo port interface GigabitEthernet1/0/25 enable

undo port interface GigabitEthernet1/0/26 enable

interface GigabitEthernet1/0/25

undo shutdown

interface GigabitEthernet1/0/26

undo shutdown’
