一、IRF 2.0概述
1、IRF(智能彈性架構)
它的核心思想是将多台裝置通過IRF實體端口連接配接在—起進行必要的配置後,虛拟化成 —台分布式裝置。使用這種虛拟化技術可以集合多台裝置的硬體資源和軟體處理能力實作多台裝置的協同工作統—管理和不間斷維護。
2、IRF的基本概念
1、角色
IRF中每台裝置都稱為成員裝置 ,成員裝置按照功能不同分為兩種角色。
Master負責管理整個IRF。
Slave作為Master的備份裝置運作。當Master故障時系統會自動從Slave中選舉一個新的Master接替原Master工作。
Master和Slave均由成員裝置選舉産生。—個IRF中同時隻能存在—台Master,其他成員裝置都是Slave。
2、IRF端口
— 種專用于IRF的邏輯接口,分為IRF-Port1和IRF-Port2, 需要和IRF實體端口綁定之後才能生效。
3、IRF 實體端口
裝置上可以用于IRF連接配接的實體端口。 IRF實體端口可能是IRF專用接口以太網接口或者光口。
二、IRF配置思路和步驟
1、配置裝置編号
[sw2]irf member 1 renumber 2 //更改裝置編号為2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[sw2]save //儲存
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.
[sw2]reboot //重新開機裝置以啟動設定
2、修改IRF優先級為5
[sw1]irf member 1 priority 5 //讓其在競選Master時獲勝
3、建立IRF端口,并綁定
[sw1]int Ten-GigabitEthernet 1/0/49
[sw1-Ten-GigabitEthernet1/0/49]shutdown
[sw1-Ten-GigabitEthernet1/0/49]quit
[sw1]irf-port 1/2 //建立裝置的IRF端口1
[sw1-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/49 //與實體端口Ten-GigabitEthernet 1/0/49綁定
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.
[sw1-irf-port1/2]quit
[sw1]int Ten-GigabitEthernet 1/0/49
[sw1-Ten-GigabitEthernet1/0/49]un sh
[sw1-Ten-GigabitEthernet1/0/49]quit
[sw1]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...
Saved the current configuration to mainboard device successfully.
[sw2]int Ten-GigabitEthernet 2/0/49
[sw2-Ten-GigabitEthernet2/0/49]shutdown
[sw2-Ten-GigabitEthernet2/0/49]quit
[sw2]irf-port 2/1 //建立裝置的IRF端口2
[sw2-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/49 //與實體端口Ten-GigabitEthernet 2/0/49綁定
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.
[sw2-irf-port2/1]quit
[sw2]int Ten-GigabitEthernet 2/0/49
[sw2-Ten-GigabitEthernet2/0/49]un sh
[sw2-Ten-GigabitEthernet2/0/49]quit
[sw2]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...
Saved the current configuration to mainboard device successfully.
4、激活IRF端口配置
[sw1]irf-port-configuration active
[sw2]irf-port-configuration active
三、配置LACP MAD檢測
1、建立兩個動态聚合端口,并配置trunk
[sw1]interface Bridge-Aggregation 2
[sw1-Bridge-Aggregation2]port link trunk
[sw1-Bridge-Aggregation2]port trunk permit vlan all
[sw1-Bridge-Aggregation2]link-aggregation mode dynamic
[sw1-Bridge-Aggregation2]mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]:
The assigned domain ID is: 0
MAD LACP only enable on dynamic aggregation interface.
[sw1-Bridge-Aggregation2]quit
[sw1]int Bridge-Aggregation 3
[sw1-Bridge-Aggregation3]port link trunk
[sw1-Bridge-Aggregation3]port trunk permit vlan all
[sw1-Bridge-Aggregation3]link-aggregation mode dynamic
[sw1-Bridge-Aggregation3]mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]:
The assigned domain ID is: 0
MAD LACP only enable on dynamic aggregation interface.
[sw1-Bridge-Aggregation3]quit
2、建立相應的聚合端口組,并配置trunk
[SW3]interface Bridge-Aggregation 2
[SW3-Bridge-Aggregation2]port link trunk
[SW3-Bridge-Aggregation2]port trunk permit vlan all
[SW3-Bridge-Aggregation2]link-aggregation mode dynamic
[SW3-Bridge-Aggregation2]quit
3、在聚合接口上添加成員,并配置trunk
[sw1]interface GigabitEthernet 1/0/1
[sw1-GigabitEthernet1/0/1]port link-type trunk
[sw1-GigabitEthernet1/0/1]port trunk permit vlan all
[sw1-GigabitEthernet1/0/1]port link-aggregation group 2 //加入2組(要相應的組号)
[sw1-GigabitEthernet1/0/1]quit
四、檢視IRF和MAD配置的顯示和維護資訊
