由于网络规模迅速扩大,当前中心交换机(Device A)转发能力已经不能满足需求,现需要在保护现有投资的基础上将网络转发能力提高一倍,并要求网络易管理、易维护。
图1-14 IRF典型配置组网图(BFD MAD检测方式)
· Device A处于局域网的汇聚层,为了将汇聚层的转发能力提高一倍,需要另外增加一台设备Device B。
· 鉴于第二代智能弹性架构IRF技术具有管理简便、网络扩展能力强、可靠性高等优点,所以本例使用IRF技术构建网络汇聚层(即在Device A和Device B上配置IRF功能),接入层设备通过聚合双链路上行。
· 为了防止万一IRF链路故障导致IRF分裂、网络中存在两个配置冲突的IRF,需要启用MAD检测功能。因为成员设备比较少,我们采用BFD MAD检测方式来监测IRF的状态。
为便于区分,下文配置中假设IRF形成前Device A的系统名称为DeviceA,Device B的系统名称为Device B。
(1) 配置设备编号
# Device A保留缺省编号为1,不需要进行配置。
# 在Device B上将设备的成员编号修改为2。
<DeviceB> system-view
[DeviceB] irf member 1 renumber 2
Warning: Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y
[DeviceB]
(2) 将两台设备断电后,按图1-14所示连接IRF链路,然后将两台设备上电。
# 在Device A上创建设备的IRF端口2,与物理端口Ten-GigabitEthernet1/0/25绑定,并保存配置。
<DeviceA> system-view
[DeviceA] interface ten-gigabitethernet 1/0/25
[DeviceA-Ten-GigabitEthernet1/0/25] shutdown
[DeviceA-Ten-GigabitEthernet1/0/25] quit
[DeviceA] irf-port 1/2
[DeviceA-irf-port1/2] port group interface ten-gigabitethernet 1/0/25
[DeviceA-irf-port1/2] quit
[DeviceA] interface ten-gigabitethernet 1/0/25
[DeviceA-Ten-GigabitEthernet1/0/25] undo shutdown
[DeviceA-Ten-GigabitEthernet1/0/25] save
# 在Device B上创建设备的IRF端口1,与物理端口Ten-GigabitEthernet2/0/26绑定,并保存配置。
<DeviceB> system-view
[DeviceB] interface ten-gigabitethernet 2/0/26
[DeviceB-Ten-GigabitEthernet2/0/26] shutdown
[DeviceB-Ten-GigabitEthernet2/0/26] quit
[DeviceB] irf-port 2/1
[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/0/26
[DeviceB-irf-port2/1] quit
[DeviceB] interface ten-gigabitethernet 2/0/26
[DeviceB-Ten-GigabitEthernet2/0/26] undo shutdown
[DeviceB-Ten-GigabitEthernet2/0/26] save
# 激活DeviceA的IRF端口配置。
[DeviceA-Ten-GigabitEthernet1/0/25] quit
[DeviceA] irf-port-configuration active
# 激活DeviceB的IRF端口配置。
[DeviceB-Ten-GigabitEthernet2/0/26] quit
[DeviceB] irf-port-configuration active
(3) 两台设备间将会进行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DeviceA。
(4) 配置BFD MAD检测
# 创建VLAN 3,并将Device A上的端口GigabitEthernet1/0/1和Device B上的端口GigabitEthernet2/0/1加入VLAN中。
<DeviceA> system-view
[DeviceA] vlan 3
[DeviceA-vlan3] port gigabitethernet 1/0/1 gigabitethernet 2/0/1
[DeviceA-vlan3] quit
# 创建VLAN接口3,并配置MAD IP地址。
[DeviceA] interface vlan-interface 3
[DeviceA-Vlan-interface3] mad bfd enable
[DeviceA-Vlan-interface3] mad ip address 192.168.2.1 24 member 1
[DeviceA-Vlan-interface3] mad ip address 192.168.2.2 24 member 2
[DeviceA-Vlan-interface3] quit
# 按图1-14所示连接BFD MAD链路。
# 因为BFD MAD和生成树功能互斥,所以在GigabitEthernet1/0/1和GigabitEthernet2/0/1上关闭生成树协议。
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-Gigabitethernet1/0/1] undo stp enable
[DeviceA-Gigabitethernet1/0/1] quit
[DeviceA] interface gigabitethernet 2/0/1
[DeviceA-Gigabitethernet2/0/1] undo stp enable

您好,请知:
以下是S5820 IRF配置命令,请参考:
1、1号设备关键配置如下:
[H3C]irf member 1 renumber 1 //将1号设备设定为成员1
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[H3C-if-range]shutdown
[H3C-if-range]quit
[H3C]irf-port 1/1 //将物理端口绑定到IRF端口
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/50
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/51
[H3C-irf-port1/1]quit
[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[H3C-if-range]undo shutdown
[H3C-if-range]quit
[H3C]irf-port-configuration active //激活IRF
[H3C]save
2、2号设备关键配置点如下:
[H3C]irf member 1 renumber 2 //将2号设备设定为成员2
[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[H3C-if-range]shutdown
[H3C-if-range]quit
[H3C]irf-port 1/2 //将物理端口绑定到IRF端口
[H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50
[H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/51
[H3C-irf-port1/2]quit
[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[H3C-if-range]undo shutdown
[H3C-if-range]quit
[H3C]irf-port-configuration active //激活IRF
[H3C]save
3、分别将成员1设备、成员2设备重启
4、测试
<H3C>dis irf //查看IRF的信息,看到成员1和成员2的设备信息都在一起
MemberID Role Priority CPU-Mac Description
*+1 Master 1 30bd-490a-0104 ---
2 Standby 1 30bd-525e-0204 ---
--------------------------------------------------
* indicates the device is the master.
+ indicates the device through which the user logs in.
The bridge MAC of the IRF is: 30bd-490a-0100

Domain ID : 0
<H3C>
<H3C>dis irf link //查看成员1、成员2 IRF链路的状态均为UP
