CR-2026-03-10: C9130AX WiFi 6 AP — Rollback

Rollback Plan

Remove the CISCO-CAPWAP-CONTROLLER DNS records and restore zone from backup:

ssh bind-01

# List backups
ls -la /var/named/*.bak.*

# Restore zone backup (replace TIMESTAMP)
TIMESTAMP=20260310
sudo cp /var/named/inside.domusdigitalis.dev.zone.bak.${TIMESTAMP} /var/named/inside.domusdigitalis.dev.zone

# Reload zones
sudo rndc reload inside.domusdigitalis.dev

# Verify records removed
dig CISCO-CAPWAP-CONTROLLER.inside.domusdigitalis.dev @10.50.1.90
# Expected: NXDOMAIN

Rollback will cause the AP to lose WLC discovery via DNS. AP will need alternative discovery method or static configuration.
