AIR-CT3504-K9 is the Cisco 3504 Wireless Controller. CAPWAP is using UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223). I'm having trouble joining a Cisco CAP3502i-A-K9 to our Cisco 2500 series WLC. A dual-homing NIC requires a VLAN or trunk between the two access switches to support the dual IP addresses on the two server links to two separate switches. Change the AP Failover Priority to critical. I have read several posts that point out that you should have QoS implemented to prioritize the CAPWAP traffic. This is useful if the AP is located remotely from the WiFi controller and other discovery techniques will not work. You must SSH to the AP, then … Capwap client server name hm-useast-XXX. grep Print lines matching a pattern. This is useful if the AP is located remotely from the WiFi controller and other discovery techniques will not work. Wanted to use an old 1242 AP in my garage, where 802. mechanisms and then sends it a CAPWAP join request. Type is always the code 0xf1 sub-option. These WLC IP addresses are learned by the AP from previously joined controllers. After that, configure option 43 hex in the dhcp pool. The IP address of the WLAN controller is also entered, otherwise, the APs are not visible by the WLAN controller. Normally after connecting AP to PoE powered Catalyst, the AP receives IP address from DHCP with option 43 that specifies the controller IP address. However you may not have DNS A records for these, especially in small deployments with no DNS server onsite. • VLAN ID: Per-SSID VLAN tagging function – when enabled, clients’ traffic which enters the AP through this SSID will be tagged with the configured VLAN ID. It is vendor specific in the sense that, in our case, only an access point would know what to do with Controller Management IP address information. Well I reset the password and (I think) was able to erase the old configuration so I could get it to use DHCP to reach out to the WLC to join. Conditions: Seen with an AP2802 or 3802 (not seen with an 1800 series. It will guide through the basic tasks of assigning IP Address, Subnet Mask and Gateway and admin username/password. localdomain. • Get the controller's IP address from a DNS server SRV (Service) record. If still AP is not joining because of a license issue (you can see this on the log of AP and WLC) you may need to reset the AP and try again. xxxx #capwap ap primary-base WLC01 192. 1 capwap ap controller ip address 10. com (Where XXX is the server number). Define the WLC gateway (in our example, the IP address of interface VLAN 219). capwap controller ip address 192. 254 AP#config capwap ap controller ip address 10. Check the state of the managed AP via either the AP List page in the AP Monitor section or the Managed AP List in the AP Control section. AP - Discover Process AP Discovery Req to known and learned WLCs Broadcast Reaches WLCs with MGMT Interface in local subnet of AP Use “ip helper-address ” with “ip forward-protocol udp” Dynamic DNS: cisco-capwap-controller DHCP: Option 43 Configured (nvram) High Availability WLCs – Pri/Sec/Ter/Backup Last WLC All WLCs in same. IPv4 Addressing. It is important to ensure there is an active DHCP server on the same VLAN/network as the AP to provide it with an IP address, subnetmask, gateway and DNS parameters. #The access point will start trying to phone home to the controller via DNS, console into it and issue the controller's IP address. AP send a layer 3 local broadcast(255. In Step 4, if you see AP Image Type is Mobility Express Image and AP Configuration is Not Mobility Express Capable, then you need to just change AP configuration to Mobility Express Capable. Designing for Cisco Internetwork Solutions (DESGN) Foundation Learning Guide: (CCDA DESGN 640-864), 3rd Edition. 1- GRE tunnels are distingutioned using SSID MAC address on the AP. Step 1: Download the latest Mobility Express release from your Cisco Smartnet portal. RFC CAPWAP Protocol Base MIB May CAPWAP Control Channel: A bi-directional flow defined by the AC IP Address, WTP IP Address, AC control. This didn't help either. Hence FlexConnect local switching feature. CAPWAP is using UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223). The AP also maintains previously learned WLC IP addresses locally in NVRAM. The following instructions show how the IP address can be set on the managed APs.
