show ap summaryWhen to Use This Command
- Checking if all access points are online after a controller reboot.
- Identifying APs that are in 'Down' or 'Disassociated' state during a network outage.
- Verifying AP model and software version consistency across the network.
- Monitoring AP join statistics to troubleshoot frequent disconnections.
Command Examples
Basic AP Summary
show ap summaryNumber of APs: 3 AP Name Slots AP Model Ethernet MAC Location Country IP Address State ... ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- AP-Office-1 2 AIR-CAP3702I-A-K9 aabb.cc00.0101 Building A Floor 1 US 192.168.1.10 Registered AP-Office-2 2 AIR-CAP3702I-A-K9 aabb.cc00.0102 Building A Floor 2 US 192.168.1.11 Registered AP-Warehouse 2 AIR-CAP2702I-A-K9 aabb.cc00.0103 Warehouse US 192.168.1.12 Down
Line 1: Total number of APs managed by the controller. Column headers: AP Name - user-configured name; Slots - number of radios; AP Model - hardware model; Ethernet MAC - AP's base MAC; Location - configured location; Country - regulatory domain; IP Address - management IP; State - operational status (Registered, Down, Disassociated). The output shows two APs are Registered (online) and one is Down (offline).
AP Summary with Filter by Name
show ap summary | include AP-OfficeAP-Office-1 2 AIR-CAP3702I-A-K9 aabb.cc00.0101 Building A Floor 1 US 192.168.1.10 Registered AP-Office-2 2 AIR-CAP3702I-A-K9 aabb.cc00.0102 Building A Floor 2 US 192.168.1.11 Registered
Using 'include' filter to show only APs with 'AP-Office' in their name. This helps narrow down specific groups of APs, e.g., to verify all office APs are up.
Understanding the Output
The 'show ap summary' command provides a high-level view of all access points managed by the wireless LAN controller. The first line indicates the total number of APs. Each subsequent line represents one AP with columns: AP Name (user-defined identifier), Slots (number of radios, typically 2 for dual-band), AP Model (e.g., AIR-CAP3702I-A-K9 indicates a 3702 series indoor AP), Ethernet MAC (unique hardware address), Location (administratively set), Country (regulatory domain code), IP Address (management IP), and State (key status: 'Registered' means fully operational, 'Down' means unreachable, 'Disassociated' means not joined, 'Downloading' means upgrading firmware). Good values: most APs show 'Registered'. Watch for 'Down' or 'Disassociated' indicating connectivity or configuration issues. Also note the AP Model column to ensure all APs are of expected types.
CCNA Exam Tips
CCNA exam may ask which state indicates an AP is fully functional: answer 'Registered'.
Be able to identify that a 'Down' state could be due to a Layer 2/3 connectivity issue or power loss.
Remember that 'show ap summary' is a quick health check; for detailed radio stats use 'show ap auto-rf' or 'show ap config general'.
The exam might test that the AP Name is configured on the controller, not on the AP itself.
Common Mistakes
Confusing 'Down' with 'Disassociated': Down means no IP connectivity, Disassociated means AP has IP but not joined the controller.
Assuming all APs must be the same model; different models are fine as long as they are supported.
Forgetting that the AP must be in 'Registered' state to serve clients; troubleshooting should start with checking this command.
