进入交换机全局配置模式,执行errdisable recovery cause ?,会看到如下信息:
    Switch(config)#errdisable recovery cause ?
     all Enable timer to recover from all causes
     bpduguard Enable timer to recover from BPDU Guard error disable state
     channel-misconfig Enable timer to recover from channel misconfig disable state
     dhcp-rate-limit Enable timer to recover from dhcp-rate-limit error disable state
     dtp-flap Enable timer to recover from dtp-flap error disable state
     gbic-invalid Enable timer to recover from invalid GBIC error disable state
     l2ptguard Enable timer to recover from l2protocol-tunnel error disable state
     link-flap Enable timer to recover from link-flap error disable state
     loopback Enable timer to recover from loopback detected disable state
     pagp-flap Enable timer to recover from pagp-flap error disable state
     psecure-violation Enable timer to recover from psecure violation disable state
     security-violation Enable timer to recover from 802.1x violation disable state
     udld Enable timer to recover from udld error disable state
     unicast-flood Enable timer to recover from unicast flood disable state
     vmps Enable timer to recover from vmps shutdown error disable state
    从列出的选项中,我们可以看出,有非常多的原因会引起端口被置于错误状态
