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 enable
