从 BPDU 防护违规中恢复
1. 当某个端口上存在 BPDU 防护违规时，OS10 将关闭该端口或将其移至 BLOCKED 状态。在 CONFIGURATION 模式下使用以下命
令关闭端口。命令的 no 版本将端口移至 BLOCKED 状态。
errdisable detect cause bpduguard
2. 在 CONFIGURATION 模式下，使用以下命令来恢复端口，使其因检测到 BPDU 防护违规而关闭。当恢复选项启用时，该端口将在
恢复计时器到期后启动。默认恢复计时器值为 60 秒。当恢复选项处于禁用状态时，该端口将保持无限期关闭。您必须使用 no
shutdown 命令手动启动端口。
errdisable recovery cause bpduguard
命令的 no 版本将禁用恢复选项。
