So we had a bad LAN controller to a HVAC system. One of the techs had issues with a port so they moved it twice to try and fix the issue of no connectivity to the HVAC system. I went in to check on this after the third attempt and I saw the three ports that were tested were in errdisabled state.
I've tried shut, no shut. Also tried to have errdisable recovery and errdisable recovery interval 300. After these few things the ports remain down and disabled.
Any ideas?
Port Name Status Reason Err-disabled Vlans
Gi2/0/38 err-disabled loopback
Gi2/0/42 err-disabled link-flap
Gi2/0/44 err-disabled link-flap
wnms-idfo-poe(config)#errdisable recovery cause psecure-violation
wnms-idfo-poe(config)#errdisable recovery interval 300
wnms-idfo-poe(config)#
wnms-idfo-poe(config)#end
wnms-idfo-poe#

wnms-idfo-poe#sh errdisable recovery
