配置DLDP监控光纤交叉相连链路示例
操作步骤
- 配置接口处于非自协商状态
<HUAWEI> system-view [HUAWEI] sysname SwitchA [SwitchA] interface gigabitethernet 0/0/1 [SwitchA-GigabitEthernet0/0/1] undo negotiation auto [SwitchA-GigabitEthernet0/0/1] quit [SwitchA] interface gigabitethernet 0/0/2 [SwitchA-GigabitEthernet0/0/2] undo negotiation auto [SwitchA-GigabitEthernet0/0/2] quit
- 在SwitchA上使能全局的DLDP功能
[SwitchA] dldp enable - 在SwitchA上使能接口的DLDP功能
[SwitchA] interface gigabitethernet 0/0/1 [SwitchA-GigabitEthernet0/0/1] dldp enable [SwitchA-GigabitEthernet0/0/1] quit [SwitchA] interface gigabitethernet 0/0/2 [SwitchA-GigabitEthernet0/0/2] dldp enable [SwitchA-GigabitEthernet0/0/2] quit
- 在SwitchA上配置发送Advertisement报文的时间间隔为10秒
[SwitchA] dldp interval 10 - 在SwitchA上配置DelayDown定时器的超时时间为4秒
[SwitchA] dldp delaydown-timer 4 - 在SwitchA上配置DLDP报文的认证方式SHA2-256方式，密码为12345
[SwitchA] dldp authentication-mode sha 12345
对SwitchB重复步骤1～步骤6。
- 验证配置结果
配置完成后，使用display dldp命令可以看到接口的DLDP状态为advertisement。
[SwitchA] display dldp interface gigabitethernet 0/0/1 Interface GigabitEthernet0/0/1 DLDP port state: advertisement DLDP link state: up The neighbor number of the port is: 1. Neighbor mac address:0001-0001-0001 Neighbor port index:26 Neighbor state:two way Neighbor aged time(s):206
[SwitchA] display dldp interface gigabitethernet 0/0/2 Interface GigabitEthernet0/0/2 DLDP port state: advertisement DLDP link state: up The neighbor number of the port is: 1. Neighbor mac address:0001-0001-0001 Neighbor port index:28 Neighbor state:two way Neighbor aged time(s):188
[SwitchB] display dldp interface gigabitethernet 0/0/1 Interface GigabitEthernet0/0/1 DLDP port state: advertisement DLDP link state: up The neighbor number of the port is: 1. Neighbor mac address:781d-ba57-c24a Neighbor port index:51 Neighbor state:two way Neighbor aged time(s):235
[SwitchB] display dldp interface gigabitethernet 0/0/2 Interface GigabitEthernet0/0/2 DLDP port state: advertisement DLDP link state: up The neighbor number of the port is: 1. Neighbor mac address:781d-ba57-c24a Neighbor port index:53 Neighbor state:two way Neighbor aged time(s):214
如图4-10所示，如果光纤交叉连接，SwitchA和SwitchB的接口GE0/0/1、GE0/0/2出现单向链路时，DLDP会自动阻塞各接口。
使用display dldp命令查看SwitchA和SwitchB的接口的DLDP状态为disable。
[SwitchA] display dldp interface gigabitethernet 0/0/1 Interface GigabitEthernet0/0/1 DLDP port state: disable DLDP link state: up The neighbor number of the port is: 0. [SwitchA] display dldp interface gigabitethernet 0/0/2 Interface GigabitEthernet0/0/2 DLDP port state: disable DLDP link state: up The neighbor number of the port is: 0.
[SwitchB] display dldp interface gigabitethernet 0/0/1 Interface GigabitEthernet0/0/1 DLDP port state: disable DLDP link state: up The neighbor number of the port is: 0. [SwitchB] display dldp interface gigabitethernet 0/0/2 Interface GigabitEthernet0/0/2 DLDP port state: disable DLDP link state: up The neighbor number of the port is: 0.
