12508f设备进行堆叠 改成irf模式为什么不自动重启

最佳答案
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1-17 IRF典型配置组网图(BFD MAD检测方式)
· 为了将Device A的转发能力提高一倍,需要另外增加一台设备Device B。即在Device A和Device B上配置IRF功能。
· 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。采用BFD MAD检测方式来监测IRF的状态。
(1) 配置Device A。
# 设置Device A的成员编号为1,成员优先级为12,创建IRF端口2,并将它与物理端口Ten-GigabitEthernet3/0/1绑定。
<Sysname> system-view
[Sysname] irf member 1
Info: Member ID change will take effect after the switch reboots and operates in IRF mode.
[Sysname] irf priority 12
[Sysname] irf-port 2
[Sysname-irf-port 2] port group interface ten-gigabitethernet 3/0/1
[Sysname-irf-port 2] quit
[Sysname] interface ten-gigabitethernet 3/0/1
[Sysname-Ten-GigabitEthernet3/0/1] undo shutdown
[Sysname-Ten-GigabitEthernet3/0/1] quit
l 将当前配置保存到下次启动配置文件。
[Sysname] save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/startup.cfg exists, overwrite? [Y/N]:y
Validating file. Please wait.....................................
The current configuration is saved to the active main board successfully.
Configuration is saved to device successfully.
l 将设备的运行模式切换到IRF模式。
<Sysname> system-view
[Sysname] chassis convert mode irf
The device will switch to IRF mode and reboot. You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y
Please wait...
Saving the converted configuration file to the main board succeeded.
Slot 1:
Saving the converted configuration file succeeded.
Now rebooting, please wait...
设备重启后Device A组成了只有一台成员设备的IRF。
(2) Device B上的配置。
# 配置Device B的成员编号为2,成员优先级为26,创建IRF端口1,并将它与物理端口Ten-GigabitEthernet3/0/1绑定。
<Sysname> system-view
[Sysname] irf member 2
Info: Member ID change will take effect after the switch reboots and operates in IRF mode.
[Sysname] irf priority 26
[Sysname] irf-port 1
[Sysname-irf-port 1] port group interface ten-gigabitethernet 3/0/1
[Sysname-irf-port 1] quit
[Sysname] interface ten-gigabitethernet 3/0/1
[Sysname-Ten-GigabitEthernet3/0/1] undo shutdown
[Sysname-Ten-GigabitEthernet3/0/1] quit
# 将当前配置保存到下次启动配置文件。
[Sysname] save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/startup.cfg exists, overwrite? [Y/N]:y
Validating file. Please wait.....................................
The current configuration is saved to the active main board successfully.
Configuration is saved to device successfully.
# 参照图1-17进行物理连线。
# 将设备的运行模式切换到IRF模式。
<Sysname> system-view
[Sysname] chassis convert mode irf
The device will switch to IRF mode and reboot. You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y
Please wait...
Saving the converted configuration file to the main board succeeded.
Slot 1:
Saving the converted configuration file succeeded.
Now rebooting, please wait...
设备B重启后与设备A形成IRF。
(3) 配置BFD MAD检测
# 创建VLAN 3,并将Device A(成员编号为1)上的端口1/4/0/1和Device B(成员编号为2)上的端口2/4/0/1加入VLAN中。
<Sysname> system-view
[Sysname] vlan 3
[Sysname-vlan3] port gigabitethernet 1/4/0/1 gigabitethernet 2/4/0/1
[Sysname-vlan3] quit
# 创建VLAN接口3,并配置MAD IP地址。
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad bfd enable
This command will enable BFD MAD on the VLAN interface. Continue? [Y/N]: Y
[Sysname-Vlan-interface3] mad ip address 192.168.2.1 24 member 1
[Sysname-Vlan-interface3] mad ip address 192.168.2.2 24 member 2
[Sysname-Vlan-interface3] quit
# 因为BFD MAD和生成树功能互斥,所以在GigabitEthernet1/4/0/1和GigabitEthernet2/4/0/1上关闭生成树协议。
[Sysname] interface Gigabitethernet 1/4/0/1
[Sysname-Gigabitethernet1/4/0/1] undo stp enable
[Sysname-Gigabitethernet1/4/0/1] quit
[Sysname] interface Gigabitethernet 2/4/0/1
[Sysname-Gigabitethernet2/4/0/1] undo stp enable

您好,请知:
手动重启看下是否能切换为IRF模式。
以下是IRF的配置举例,请参考:
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
