一、DHCP中继

    vlan 1 create byport 1 name "VLAN-1″
    vlan 1 ports add 1/1
    vlan 1 ip create 10.1.1.1/255.255.255.0
    vlan 1 ip dhcp-relay enable
    ip dhcp-relay create-fwd-path agent 10.1.1.1 server 10.1.2.1 mode bootp_dhcp state enable
    二、端口镜像
    diag mirror-by-port 1 create in-port 1/1 out-port 10/1
    diag mirror-by-port 1 enable enable
    diag mirror-by-port 1 mode both
    三、关闭广播、组播端口保护
    ethernet 1/1 cp-limit disable multicast-limit 25000 broadcast-limit 20000
    四、配置VRRP
    交换机1
    vlan 1 create byport 1 name "VLAN-1″
    vlan 1 ports add 1/1,2/1   //***2/1用于交换机互联
    vlan 1 ip create 10.1.1.1/255.255.255.0
    vlan 1 ip vrrp 1 address 10.31.0.254
    vlan 1 ip vrrp 1 backup-master enable
    vlan 1 ip vrrp 1 fast-adv-enable enable
    vlan 1 ip vrrp 1 holddown-timer 4
    vlan 1 ip vrrp 1 priority 250
    vlan 1 ip vrrp 1 enable
    ethernet 2/1 perform-tagging enable   //***打tag,即封装DOT1Q
    交换机2
    vlan 1 create byport 1 name "VLAN-1″
    vlan 1 ports add 1/1,2/1   //***2/1用于交换机互联
    vlan 1 ip create 10.1.1.2/255.255.255.0
    vlan 1 ip vrrp 1 address 10.1.1.254
    vlan 1 ip vrrp 1 backup-master enable
    vlan 1 ip vrrp 1 fast-adv-enable enable
    vlan 1 ip vrrp 1 holddown-timer 4
    vlan 1 ip vrrp 1 enable
    ethernet 2/1 perform-tagging enable
    五、配置syslog
    sys syslog host 1 create
    sys syslog host 1 address 10.2.1.100
    sys syslog host 1 host enable
    sys syslog host 1 severity info warning error fatal
    六、配置MLT
    mlt 1 create
    mlt 1 add ports 3/1-3/4
    mlt 1 name "MLT-1″
    mlt 1 perform-tagging enable //***不用在端口下打tag

    vlan 10 ports add-mlt 1      //***mlt1允许vlan10数据通过

 七、配置SMLT
    共三台交换机，核心1、2以及接入交换机1,核心之间通过IST维护SMLT,并建立SMLT,接入1的两个端口配置MLT分别接入两台核心。SMLT无需生成树机制，实现了二层的loadbalance,8600系列可创建32组，Single Port SMLT模式（服务器loadbalance）没有组数限制。
    核心1
    mlt 10 create
    mlt 10 add ports 4/1-4/2
    mlt 10 name "MLT-IST"
    mlt 10 perform-tagging enable
    mlt 10 ist create ip 192.168.168.2 vlan-id 100  //***对端核心IP
    mlt 10 ist enable
    mlt 20 create
    mlt 20 add ports 4/3
    mlt 20 name "MLT-SWITCH1_1/1″
    mlt 20 perform-tagging enable
    mlt 20 smlt create smlt-id 20
    vlan 100 create byport1 name "IST"
    vlan 100 add-mlt 10
    vlan 100 add-mlt 20
    vlan 100 ip create 192.168.168.1/255.255.255.252
    ethernet 4/1-4/3 stg 1 stp disable
    核心2
    mlt 10 create
    mlt 10 add ports 4/1-4/2
    mlt 10 name "MLT-IST"
    mlt 10 perform-tagging enable
    mlt 10 ist create ip 192.168.168.1 vlan-id 100  //***对端核心IP
    mlt 10 ist enable
    mlt 20 create
    mlt 20 add ports 4/3
    mlt 20 name "MLT-SWITCH1_1/2″
    mlt 20 perform-tagging enable
    mlt 20 smlt create smlt-id 20
    vlan 100 create byport1 name "IST"
    vlan 100 add-mlt 10
    vlan 100 add-mlt 20
    vlan 100 ip create 192.168.168.2/255.255.255.252
    ethernet 4/1-4/3 stg 1 stp disable
    接入1
    mlt 1 create
    mlt 1 add ports 1/1-1/2
    mlt 1 name "MLT-CORE_4/3″
    mlt 1 perform-tagging enabl
