Errdisable Recovery for L2 Security
Layer 2 Security Hardening, Lab 9/10. You will enable automatic errdisable recovery on a campus access switch so ports shut down by Layer-2 security (Dynamic ARP Inspection, DHCP rate-limit, or storm control) can return to service automatically after a safe interval. The switch already enforces DHCP snooping with a correct trust boundary, DAI validation, and broadcast/multicast/unicast storm-control with shutdown actions. Your job: turn on errdisable auto-recovery for arp-inspection, dhcp-rate-limit, and storm-control, and set the interval to 60 seconds. Verify with show errdisable recovery.
