(eNSP)主备接口备份配置

news 2025/5/22 9:01:50

1.实验拓扑

2.基本配置

配置主备接口备份基本功能，当主接口及所在直连链路因故障而无法进行业务传输时，启用备份接口，以提高业务传输的可靠性。

#sysname R1
#

3.重点配置

ip address 10.1.1.1 255.255.255.0
standby interface GigabitEthernet2/0/2 30
standby interface GigabitEthernet2/0/1 20
standby timer delay 10 10

4.命令格式

standby timer delay命令用来配置主备接口切换延时。

undo standby timer delay命令用来恢复主备接口切换延时为缺省值。

缺省情况下，主备接口切换延时为5秒。

standby timer delay enable-delay disable-delay

undo standby timer delay

enable-delay	指定主接口切换到备份接口的延时。	取值范围是0～65535，单位是秒。缺省延时为5秒。
disable-delay	指定备份接口切换到主接口的延时。	取值范围是0～65535，单位是秒。缺省延时为5秒。
