• 【实验】 M-LAG


    2.M-LAG(跨设备的堆叠)
    链路聚合
    peer-link协商M-LAG
    Keepalive链路是3层的保活链路,要求IP可达
    DFS组去同步状态信息。(心跳线)
    选举规则:1)优先级较大(1-254) 2)系统MAC较小的成为主设备
    实施:
    1)接入的5700的常规以太聚合
    interface GigabitEthernet0/0/5
    eth-trunk 20
    #
    return
    [S5700-Eth-Trunk20]dis cu int g0/0/6
    #
    interface GigabitEthernet0/0/6
    eth-trunk 20
    interface Eth-Trunk20
    mode lacp
    port link-type trunk
    port trunk allow-pass vlan 2 to 4094

    2)2台生成树的基本调整和开启V-STP
    [6850-Y]stp mode rstp
    [6850-Y]stp v-stp enable

    3)DFS的源地址和DFS组 (keep-alive链路)
    [6850-X]int 10GE 1/0/3
    [6850-X-10GE1/0/3]undo portswitch
    [6850-X-10GE1/0/3]ip address 10.1.1.1 30
    [6850-X-10GE1/0/3]description DFS-SOURCE

    [6850-Y]int 10GE 1/0/3
    [6850-Y-10GE1/0/3]undo portswitch
    [6850-Y-10GE1/0/3]ip address 10.1.1.2 30
    [6850-Y-10GE1/0/3]description DFS-SOURCE

    配置DFS组
    [6850-X-dfs-group-1]dis th
    dfs-group 1
    priority 254
    source ip 10.1.1.1
    [6850-Y-dfs-group-1]dis th
    #
    dfs-group 1
    priority 120
    source ip 10.1.1.2


    [6850-X]dis dfs-group 1
    Dfs-Group ID : 1
    Priority : 254
    UDP Port : 61467 (active)
    Address : ip address 10.1.1.1
    System ID : 340a-9867-b8c1
    SysName : 6850-X
    Up-delay : 120
    Switch-delay : 0


    4)配置对等体链路聚合(2层)(peer link)
    [6850-X]int Eth-Trunk 10
    [6850-X-Eth-Trunk10]trunkport 10GE 1/0/1 to 1/0/2
    [6850-X-Eth-Trunk10]mode lacp-static
    [6850-X-Eth-Trunk10]peer-link 1 //接口配置为peer-link接口后,缺省加入所有VLAN。接口配置为peer-link接口后,该接口上不能再配置其他业务。
    [6850-X-Eth-Trunk10]description Peer-Link-2CENG

    [6850-Y-Eth-Trunk10]dis th
    #
    interface Eth-Trunk10
    description PEER-LINK
    mode lacp-static
    peer-link 1


    [6850-Y-Eth-Trunk10]dis cu int 10g 1/0/1
    #
    interface 10GE1/0/1
    eth-trunk 10
    #
    return
    [6850-Y-Eth-Trunk10]dis cu int 10g 1/0/2
    #
    interface 10GE1/0/2
    eth-trunk 10


    验证peer-link链路
    [6850-Y]dis eth-trunk 10
    Eth-Trunk10's state information is:
    Local:
    LAG ID: 10 Working Mode: Static
    Preempt Delay: Disabled Hash Arithmetic: profile default
    System Priority: 32768 System ID: 20f1-7cbd-52f1
    Least Active-linknumber: 1 Max Active-linknumber: 16
    Operating Status: up Number Of Up Ports In Trunk: 2
    Timeout Period: Slow

    Total Interface(s): 1
    Peer-link Id : 1

    5)配置下联交换机的M-LAG成员链路
    [6850-Y]int Eth-Trunk 20
    [6850-Y-Eth-Trunk20]trunkport 10GE 1/0/6
    [6850-Y-Eth-Trunk20] mode lacp-static
    [6850-Y-Eth-Trunk20] dfs-group 1 m-lag 1

    数据测试:
    CE:
    VLAN,trunk,VLANIF
    interface Eth-Trunk20
    port link-type trunk
    port trunk allow-pass vlan 10
    [6850-Y-Vlanif10]dis th
    #
    interface Vlanif10
    ip address 10.10.10.254 255.255.255.0
    mac-address 0001-0001-0001
    [6850-X-Vlanif10]dis th
    #
    interface Vlanif10
    ip address 10.10.10.254 255.255.255.0
    mac-address 0001-0001-0001
    解决日志问题
    undo snmp-agent trap enable feature-name arp trap-name hwethernetarpmacipconflict

    MAC地址表的同步
    [6850-Y]dis mac-address
    Flags: * - Backup
    # - forwarding logical interface, operations cannot be performed based
    on the interface.
    BD : bridge-domain Age : dynamic MAC learned time in seconds
