7.4 替代方案

3.iStack（堆叠技术）配置（华三模拟器）

1）配置SW1

[SW1]irf member 1 priority 2
[SW1]interface range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[SW1-if-range]shutdown
[SW1-if-range]quit

[SW1]irf-port 1/2
[SW1-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50
[SW1-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/51
[SW1-irf-port1/2]quit

[SW1]interface range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[SW1-if-range]undo shutdown
[SW1-if-range]quit

[SW1]save force
[SW1]irf-port-configuration active

2）配置SW2

[SW2]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[SW2]save force

[SW2]quit
<SW2>reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
This command will reboot the device. Continue? [Y/N]:y
[SW2]interface range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51
[SW2-if-range]shutdown
[SW2-if-range]quit

[SW2]irf-port 2/1
[SW2-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/50
[SW2-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/51
[SW2-irf-port2/1]quit

[SW2]interface range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51
[SW2-if-range]undo shutdown
[SW2-if-range]quit

[SW2]save force
[SW2]irf-port-configuration active

3）查看接口信息及irf信息

[SW1]display interface brief
Brief information on interfaces in route mode:
Link: ADM - administratively down; Stby - standby
Protocol: (s) - spoofing

NULL0                UP   UP(s)    --
REG0                 UP   --       --

[SW1]display irf
MemberID    Role    Priority  CPU-Mac         Description
 *+1        Master  32        9227-6d3b-0104  ---
   2        Standby 1         9227-729c-0204  ---
 * indicates the device is the master.
 + indicates the device through which the user logs in.
