Automatic Err-Disable Recovery

Someone showed me a great feature today. One of the constant pains in the network is when you get a port err-disabled on the switch. Regardless of how many times I see it, it always seems to be the last thing I check. There's a little-known feature in the IOS called "err-disable recovery" which automatically turns a err-disabled switchport back on after 5 minutes (by default). The good news is that this command allows you to choose specific reasons where you'd like to re-enable the port, such as re-enabling ports disabled because of a port-flap instance but keeping mac-address security violations error disabled. Here's the syntax to make it happen:

CAT3550#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
CAT3550(config)#errdisable recovery ?
cause     Enable error disable recovery for application
interval  Error disable recovery timer value
CAT3550(config)#errdisable recovery cause ?
all                   Enable timer to recover from all error causes
arp-inspection        Enable timer to recover from arp inspection error
disable state
bpduguard             Enable timer to recover from BPDU Guard error

link-flap             Enable timer to recover from link-flap error
link-monitor-failure  Enable timer to recover from link monitoring failure
loopback              Enable timer to recover from loopback error
mac-limit             Enable timer to recover from mac limit disable state
oam-remote-failure    Enable timer to recover from OAM detected remote
failure
pagp-flap             Enable timer to recover from pagp-flap error
port-mode-failure     Enable timer to recover from port mode change failure
psecure-violation     Enable timer to recover from psecure violation error
security-violation    Enable timer to recover from 802.1x violation error
sfp-config-mismatch   Enable timer to recover from SFP config mismatch error
storm-control         Enable timer to recover from storm-control error
udld                  Enable timer to recover from udld error
unicast-flood         Enable timer to recover from unicast flood error
vmps                  Enable timer to recover from vmps shutdown error
CAT3550(config)#errdisable recovery cause link-flap
CAT3550(config)#^Z
