当下游设备连接到上游设备时,使用单上行方式容易出现单点故障,造成业务中断。因此通常采用双上行方式,即将一台下游设备同时连接到两台上游设备,以最大限度地避免单点故障,提高网络可靠性,如图1-1所示。
图1-1 Smart Link应用场景示意图
双上行组网虽然能提高网络可靠性,但又引入了环路问题。通常可通过STP(Spanning Tree Protocol,生成树协议)或RRPP(Rapid Ring Protection Protocol,快速环网保护协议)来消除环路,但STP在收敛速度上只能达到秒级,不适用于对收敛时间有很高要求的用户,而RRPP尽管在收敛速度上能达到要求,但组网配置的复杂度较高,主要适用于较复杂的环形组网。
为了在满足用户对链路快速收敛要求的同时又能简化配置,我们针对双上行组网提出了Smart Link解决方案,实现了主备链路的冗余备份,并在主用链路发生故障后使流量能够迅速切换到备用链路上,因此具备较高的收敛速度。Smart Link的主要特点如下:
l 专用于双上行组网;
l 收敛速度快(达到亚秒级);
l 配置简单,便于用户操作。
l Device C和Device D均连接VLAN1~20的用户网络,且Device C和Device D均采用双上行链路连接到Device A。
l 通过配置,在Device C和Device D上分别实现双上行链路的灵活备份,且Device C上的流量优先选择经Device B向Device A转发;Device D上的流量优先选择经Device E向Device A转发。

l 如果打算配置某端口为Smart Link组成员端口(即主端口和副端口),则需先手工关闭该端口,待Smart Link组配置完成后,再开启该端口,以避免形成环路,导致广播风暴。
l 如果打算配置某端口为Smart Link组成员端口,则需关闭该端口的STP功能和RRPP功能,并确保该端口不是聚合成员端口和业务环回组成员端口。
l 需要为不同的Smart Link组配置不同的控制VLAN。
l 用户需要配置保证控制VLAN存在,且Smart Link组的端口允许控制VLAN的报文通过。
l 某Smart Link组的控制VLAN应同时为该Smart Link组的保护VLAN,且不要将已配置为控制VLAN的VLAN删除,否则会影响Flush报文的发送。
l 配置相关设备时,建议在其与Smart Link组的成员端口直接相连的端口上关闭生成树协议,以免由于网络拓扑改变时端口状态尚未迁移到Forwarding而导致Flush报文被丢弃。
l 在相关设备上配置的接收处理Flush报文的控制VLAN和在Smart Link设备上配置的发送控制VLAN要相同,如果二者不相同,相关设备将对接收到的Flush报文不做处理直接转发。
在同一个环网中,可能同时存在多个VLAN的数据流量,Smart Link可以实现流量的负载分担,即不同VLAN的流量沿不同Smart Link组所确定的路径进行转发。
通过把一个端口配置为多个Smart Link组的成员端口(每个Smart Link组的保护VLAN不同),且该端口在不同组中的转发状态不同,这样就能实现不同VLAN的数据流量的转发路径不同,从而达到负载分担的目的。
图1-3 配置多Smart Link组负载分担组网图
l Device C上VLAN 1~20的流量通过Device B和Device D双上行到Device A。
l 通过配置,在Device C上实现双上行链路的灵活备份和负载分担:VLAN 1~10的流量经Device B向Device A转发,VLAN 11~20的流量经Device D向Device A转发。

l 如果打算配置某端口为Smart Link组成员端口(即主端口和副端口),则需先手工关闭该端口,待Smart Link组配置完成后,再开启该端口,以避免形成环路,导致广播风暴。
l 如果打算配置某端口为Smart Link组成员端口,则需关闭该端口的STP功能和RRPP功能,并确保该端口不是聚合成员端口和业务环回组成员端口。
l 需要为不同的Smart Link组配置不同的控制VLAN。
l 用户需要配置保证控制VLAN存在,且Smart Link组的端口允许控制VLAN的报文通过。
l 某Smart Link组的控制VLAN应同时为该Smart Link组的保护VLAN,且不要将已配置为控制VLAN的VLAN删除,否则会影响Flush报文的发送。
l 配置相关设备时,建议在其与Smart Link组的成员端口直接相连的端口上关闭生成树协议,以免由于网络拓扑改变时端口状态尚未迁移到Forwarding而导致Flush报文被丢弃。
l 在相关设备上配置的接收处理Flush报文的控制VLAN和在Smart Link设备上配置的发送控制VLAN要相同,如果二者不相同,相关设备将对接收到的Flush报文不做处理直接转发。
Monitor Link是一种端口联动方案,主要用于配合二层拓扑协议的组网应用,监控设备上行链路,根据上行链路的up/down状态变化来触发下行链路的up/down变化,从而触发下游设备上拓扑协议所控制备份链路的切换。
图2-1 Monitor Link配合Smart Link应用组网图
l 设备Device C通过多Smart Link组将VLAN 1~10和VLAN 11~20的流量分别沿不同的路径双上行到设备Device A,具体配置请参见1.3 多Smart Link组实现负载分担典型配置指导;
l 当Device A与Device B(或Device D)之间出现链路故障时,Device C能够感知到这个故障并完成其上行链路的切换。

Device A~Device D上已经完成Smart Link组的配置,具体请参见1.3 多Smart Link组实现负载分担典型配置指导。
(1) 配置Device B
# 创建Monitor Link组1。
<DeviceB> system-view
[DeviceB] monitor-link group 1
# 配置Monitor Link组1的上行链路为端口GigabitEthernet1/0/1,下行链路为端口GigabitEthernet1/0/2。
[DeviceB-mtlk-group1] port gigabitethernet 1/0/1 uplink
[DeviceB-mtlk-group1] port gigabitethernet 1/0/2 downlink
[DeviceB-mtlk-group-1] quit
(2) 配置Device D
# 创建Monitor Link组1。
<DeviceD> system-view
[DeviceD] monitor-link group 1
# 配置Monitor Link组1的上行链路为端口GigabitEthernet1/0/1,下行链路为端口GigabitEthernet1/0/2。
[DeviceD-mtlk-group1] port gigabitethernet 1/0/1 uplink
[DeviceD-mtlk-group1] port gigabitethernet 1/0/2 downlink
[DeviceD-mtlk-group1] quit
(3) 检验配置效果
通过使用display monitor-link group命令可以查看各设备上Monitor Link组的信息。例如当Device A的端口GigabitEthernet1/0/2由于链路故障而down掉时:
# 查看Device B上Monitor Link组1的信息。
[DeviceB] display monitor-link group 1
Monitor link group 1 information:
Group status: UP
Last-up-time: 16:37:20 2010/02/21
Last-down-time: 16:35:26 2010/02/21
Member Role Status
------------------------------------------
GigabitEthernet1/0/1 UPLINK UP
GigabitEthernet1/0/2 DOWNLINK UP
# 查看Device D上Monitor Link组1的信息。
[DeviceD] display monitor-link group 1
Monitor link group 1 information:
Group status: DOWN
Last-up-time: 16:35:27 2010/02/21
Last-down-time: 16:37:19 2010/02/21
Member Role Status
------------------------------------------
GigabitEthernet1/0/1 UPLINK DOWN
GigabitEthernet1/0/2 DOWNLINK DOWN
Device A~Device D上已经完成Smart Link组的配置,具体请参见1.3.5 完整配置。
l Device B上的配置
#
monitor-link group 1
#
interface GigabitEthernet1/0/1
port monitor-link group 1 uplink
#
interface GigabitEthernet1/0/2
port monitor-link group 1 downlink
#
l Device D上的配置
#

l 如果欲配置某端口为Monitor Link组的成员端口(上行端口或下行端口),需确保该端口不是聚合成员端口或业务环回组成员端口。
l Monitor Link组的成员端口可以是二层以太网端口或二层聚合接口。
l 一个端口只能属于一个Monitor Link组。
l 建议先配置Monitor Link的上行端口,以避免下行端口出现不必要的down/up状态变化。
