IRF配置和LACP MAD配置思路

Posted 2020-11-30

IRF配置思路和步骤


1）配置设备编号。sw1保留默认编号为1，不需要进行配置。在sw2上将设备的成员编号修改为2。

<sw2>system-view
[sw2]irf member 1 renumber 2
[sw2]save
[sw2]reboot
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]y

2）将两台设备断电后，然后将两台设备上电。修改sw1的IRF优先级为5，目的是让其在竞选时获胜。

<sw1>system-view
[sw1]irf member 1 priority 5
[sw1]int Ten-GigabitEthernet1/0/49
[sw1-Ten-GigabitEthernet1/0/49]shutdown
[sw1-Ten-GigabitEthernet1/0/49]quit
[sw1]irf-port 1/2
[sw1-irf-port1/2]port group int Ten-GigabitEthernet 1/0/49
[sw1-irf-port1/2]quit
[sw1]int Ten-GigabitEthernet1/0/49
[sw1-Ten-GigabitEthernet1/0/49]undo shutdown
[sw1-Ten-GigabitEthernet1/0/49]save

3）保存sw2上创建设备的IRF端口1，与物理端口ten-g2/0/49绑定，病保存配置。

<H3C>system-view
[sw2]int Ten-GigabitEthernet 2/0/49
[sw2-Ten-GigabitEthernet2/0/49]shutdown
[sw2-Ten-GigabitEthernet2/0/49]quit
[sw2]irf-port 2/1
[sw2-irf-port2/1]port group int Ten-GigabitEthernet 2/0/49
[sw2-irf-port2/1]quit
[sw2]int Ten-GigabitEthernet 2/0/49
[sw2-Ten-GigabitEthernet2/0/49]undo shutdown
[sw2]int Ten-GigabitEthernet 2/0/49
[sw2-Ten-GigabitEthernet2/0/49]save

4）激活sw1和sw2的IRF端口配置。

[sw1]irf-port-configuration active
[sw2]irf-port-configuration active

两台设备间会进行Master竞选，竞选失败的一方将自动重启，重启完成后，IRF形成，系统名称统一为sw1。

配置LACP MAD检测
1）在sw1上配置。

interface Bridge-Aggregation  2
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 mad enable
quit

interface Bridge-Aggregation  3
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 mad enable
quit

2）在sw3，sw4上创建相应的聚合端口组，并配置trunk。

SW3：
 interface Bridge-Aggregation  2
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 quit
SW4:
interface Bridge-Aggregation  3
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 quit

3）分别在SW1，SW3，SW4上的聚合接口上添加成员，并配置trunk。
如：（注意要对应相应的组号）。

interface GigabitEthernet1/0/1
 port link-type trunk
 port trunk permit vlan all
 port link-aggregation group 2

4）查看IRF和MAD配置的显示和维护信息

1、display irf
2、display irf  configuration
3、display  mad  verbose
4、display   link-aggregation   verbose

5）创建vlan，并将相应的接口加入vlan中：

vlan 2
quit
vlan 3
quit

int g1/0/3
port  link-type  access
port  access  vlan 2
quit
