An uplink experiences intermittent packet drops but the alert policy watches link state only is a separate situation normally addressed by: Configure counter-based thresholds for errors, discards and congestion alongside availability checks. This change record concerns a different issue, specifically: An alert policy monitors only aggregate AP count and misses client failures concentrated in one school floor.

An administrator updates the RADIUS policy for one classroom but a broad wildcard matches every school WLAN is a separate situation normally addressed by: Narrow the policy condition to the intended SSID, identity group and site attributes. This change record concerns a different issue, specifically: An alert policy monitors only aggregate AP count and misses client failures concentrated in one school floor.

A school admin authorizes changing the WLAN display name but the rollout unintentionally changes its authentication policy is a separate situation normally addressed by: Separate the SSID name change from the existing security profile and reapply the approved authentication settings. This change record concerns a different issue, specifically: An alert policy monitors only aggregate AP count and misses client failures concentrated in one school floor.

Record the new subnet, gateway, DHCP scope and owner in the IPAM documentation belongs to a different operational case: A campus SSID receives an additional client VLAN but the IP address management register is unchanged. It does not target the specific issue here; the intended remedy is: Extend IPAM to include IPv6 prefixes, router advertisements and DHCPv6 role where applicable.

Extend capacity through an approved nonoverlapping address allocation or properly sized scope change belongs to a different operational case: A campus VLAN's DHCP scope is nearly exhausted because the department added more managed clients. It does not target the specific issue here; the intended remedy is: Extend IPAM to include IPv6 prefixes, router advertisements and DHCPv6 role where applicable.

A captive guest registration issue is fixed but the team only tests a browser session that retained old authorization is a separate situation normally addressed by: Test a fresh unauthenticated guest from portal discovery through approved post-login access.
