IRF简书以及使用H3C模拟器HCL完成基础的IRF实施

第1部分 IRF简书

1.什么是IRF

2.IRF的成员组成和接口类型

IRF堆叠中的成员设备分为Master和Slave设备成员设备上用于堆叠连接的物理接口称之为物理堆叠口物理堆叠口需要和逻辑堆叠口绑定，逻辑堆叠口简称为堆叠口由多个物理堆叠口聚合的堆叠口成为聚合堆叠口

3. IRF拓扑和拓扑发现

第2部分 IRF实施案例

2.1实施拓扑：

[IRF2]irf member 1 renumber 2 //将IRF2(即SW2)的成员编号设置为2，默认为1 Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y //对成员1中的背板重编号必须可能导致配置改变或者丢弃，是否继续？是 [IRF2]save //切记保存配置 The current configuration will be written to the device. Are you sure? [Y/N]:y //确定保存 Please input the file name(*.cfg)[flash:/startup.cfg] (To leave the existing filename unchanged, press the enter key): //使用默认的配置名称，即start.cfg Validating file. Please wait... Saved the current configuration to mainboard device successfully. [IRF2]quit reboot //必须重启设备 Start to check configuration with next startup configuration file, please wait.........DONE! This command will reboot the device. Continue? [Y/N]:y //该命令将重启设备，继续么？确认继续 Now rebooting, please wait... %Nov 25 22:02:11:207 2018 IRF2 DEV/5/SYSTEM_REBOOT: System is rebooting now. ！ ！ [H3C]sysname IRF1 [IRF1]irf member 1 priority 32 //设置IRF1（SW1）的IRF优先级为32，该值已经最大，保证IRF1设备成为主设备（IRF2并未修改优先级，意味着它使用默认的优先级1） [IRF1]int r te 1/0/50 to t 1/0/51 [IRF1-if-range]shu //把交换机互联接口关闭，这是必须的一部 [IRF1-if-range]quit [IRF1]irf-port 1/2 //设置IRF1的逻辑接口2 [IRF1-irf-port1/2]port g int te 1/0/50 //把物理接口加入逻辑接口 You must perform the following tasks for a successful IRF setup: Save the configuration after completing IRF configuration. Execute the "irf-port-configuration active" command to activate the IRF ports. [IRF1-irf-port1/2]port g int te 1/0/51 //把物理接口加入逻辑接口 [IRF1-irf-port1/2]quit [IRF1]int r te 1/0/50 to t 1/0/51 [IRF1-if-range]un sh //开启物理接口

步骤2. Slave设备加入物理成员接口

[IRF2]int r t 2/0/50 to t 2/0/51 //进入物理接口，注意之前已经“renember”了该设备的板卡号码，所以接口为10G接口的2/0/50和51接口 [IRF2-if-range]shu //IRF2设备重启后关闭物理接口 [IRF2-if-range]quit [IRF2]irf-port 2/1 //注意，特别推荐使用交叉互联，请对比IRF1设备，否则可能造成堆叠失败 [IRF2-irf-port2/1]port g int t 2/0/50 //把物理接口加入逻辑接口 You must perform the following tasks for a successful IRF setup: Save the configuration after completing IRF configuration. Execute the "irf-port-configuration active" command to activate the IRF ports. [IRF2-irf-port2/1]port g int t 2/0/51 //把物理接口加入逻辑接口 [IRF2-irf-port2/1]quit [IRF2]int r t 2/0/50 to t 2/0/51 [IRF2-if-range]un shu //开启物理接口 %Nov 25 22:06:39:426 2018 IRF2 IFNET/3/PHY_UPDOWN: Physical state on the interface Ten-GigabitEthernet2/0/50 changed to up. %Nov 25 22:06:39:474 2018 IRF2 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Ten-GigabitEthernet2/0/50 changed to up. %Nov 25 22:06:39:495 2018 IRF2 LLDP/6/LLDP_CREATE_NEIGHBOR: Nearest bridge agent neighbor created on port Ten-GigabitEthernet2/0/50 (IfIndex 179), neighbor's chassis ID is 90c6-26d7-0100, port ID is Ten-GigabitEthernet1/0/50. %Nov 25 22:06:39:648 2018 IRF2 IFNET/3/PHY_UPDOWN: Physical state on the interface Ten-GigabitEthernet2/0/51 changed to up. [IRF2-if-range]%Nov 25 22:06:39:659 2018 IRF2 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Ten-GigabitEthernet2/0/51 changed to up. %Nov 25 22:06:39:663 2018 IRF2 LLDP/6/LLDP_CREATE_NEIGHBOR: Nearest bridge agent neighbor created on port Ten-GigabitEthernet2/0/51 (IfIndex 180), neighbor's chassis ID is 90c6-26d7-0100, port ID is Ten-GigabitEthernet1/0/51. [IRF2]save //保存配置 The current configuration will be written to the device. Are you sure? [Y/N]:y //确定保存配置 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 //确定覆盖已经存在的配置 Validating file. Please wait... Saved the current configuration to mainboard device successfully. save //保存配置 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): Validating file. Please wait... Saved the current configuration to mainboard device successfully.

此时2台设备的IRF已经配置完毕，但不激活IRF之前，IRF并不工作

步骤3.激活IRF配置

[IRF1]irf-port-configuration active //请在激活IRF配置前确保已经保存配置 [IRF1]%Nov 25 22:08:28:132 2018 IRF1 STM/6/STM_LINK_UP: IRF port 2 came up. %Nov 25 22:08:45:321 2018 IRF1 STM/4/STM_MERGE: IRF merge occurred. %Nov 25 22:08:47:660 2018 IRF1 IFNET/3/PHY_UPDOWN: Physical state on the interface Ten-GigabitEthernet1/0/51 changed to down. %Nov 25 22:08:47:668 2018 IRF1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Ten-GigabitEthernet1/0/51 changed to down. %Nov 25 22:08:49:594 2018 IRF1 STM/3/STM_LINK_DOWN: IRF port 2 went down. %Nov 25 22:08:49:606 2018 IRF1 IFNET/3/PHY_UPDOWN: Physical state on the interface Ten-GigabitEthernet1/0/50 changed to down. %Nov 25 22:08:49:612 2018 IRF1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Ten-GigabitEthernet1/0/50 changed to down. [IRF1] [IRF2]%Nov 25 22:08:46:254 2018 IRF2 STM/6/STM_LINK_UP: IRF port 1 came up.//已经重启 system-view //在IRF设备重启后，暂时不会完成立即IRF，此时依旧显示“IRF2” System View: return to User View with Ctrl+Z. [IRF2]int r t 2/0/50 to t 2/0/51 [IRF2-if-range]shu [IRF2-if-range]und shu //重新关闭关闭，开启物理接口。此时可能已经重启

启动后，如果成功那么IRF2会变成IRF1步骤4，IRF实施完毕后的验证

chassis convert mode irf //切换到IRF工作模式（模拟器不支持）其他厂商还支持VSS、CSS等类似技术，敬请期待乾颐堂安德培训和课程（QCNA、QCIE）
