auditing activities are logged into the security log. All events that are DHCP-specific are logged into the System log. dhcp reconcile The DHCP system event log contains events that are associated with DHCP service and DHCP server activities, such as when the DHCP server started and stopped, when DHCP leases are https://technet.microsoft.com/en-us/library/cc774806(v=ws.10).aspx close to being depleted, and when the DHCP database is corrupt. A few DHCP system event log IDs are listed below: Event ID 1037 (Information): Indicates that the DHCP server has begun to clean up the DHCP database. Event ID 1038 (Information): Indicates that the DHCP server cleaned up the DHCP database for unicast addresses: 0 IP address leases were http://www.tech-faq.com/monitoring-and-troubleshooting-the-dhcp-server.html recovered. 0 records were deleted. Event ID 1039 (Information): Indicates that the DHCP server cleaned up the DHCP database for multicast addresses: 0 IP address leases were recovered. 0 records were deleted. Event ID 1044 (Information): Indicates that the DHCP server has concluded that it is authorized to start and is currently servicing DHCP client requests for IP addresses. Event ID 1042 (Warning): Indicates that the DHCP service running on the server has detected servers on the network.

Refer to Cisco Technical Tips Conventions for more information on document conventions. Error Messages FAQ Q. We have begun the conversion of more than 200 access points (APs) from Cisco IOS Software to event id Lightweight AP Protocol (LWAPP) with a Cisco 4404 WLC. We have completed the conversion of 48 APs and we receive a message on the WLC that states: [ERROR] spam_lrad.c 4212: AP cannot join because the maximum number of APs on interface 1 is reached. Why does the error occur? A. You must create additional AP-manager interfaces in order to support more than 48 APs. Otherwise, you receive the error that looks like this: prevent dhcp 1020 Wed Sep 28 12:26:41 2005 [ERROR] spam_lrad.c 4212: AP cannot join because the maximum number of APs on interface 1 is reached. Configure multiple AP-manager interfaces and configure primary/backup ports that other AP-manager interfaces do not use. You must create a second AP-manager interface in order to bring up additional APs. But, make sure that your primary port and backup port configurations for each manager do not overlap. In other words, if AP-manager 1 uses port 1 as the primary and port 2 as the backup, AP-manager 2 must use port 3 as the primary and port 4 as the backup. Q. I have a Wireless LAN Controller (WLC) 4402 and I use 1240 lightweight access points (LAPs). I am trying to enable 128-bit encryption on the WLC. When I select 128-bit WEP encryption on the WLC, I receive an error that says that 128-bit is not supported on the 1240s: [ERROR] spam_lrad.c 12839: Not creating SSID mde on CISCO AP xx:xx:xx:xx:xx:xx because WEP128 bit is not supported. Why do I receive this error? A. The key lengths shown on the WLCs are actually the number of bits that are in the shared secret and do not include the 24-bits of the Initialization Vector (IV). Many products, which includes the Aironet products, call it a 1

You know, humans are strange creatures. Whenever there is a shortage of a certain resource, that resource becomes more valuable to everyone, even for those who don't really need it. Maybe some of your users have heard that IP addresses are rare these days and have started collecting them for hard times. Considering that public IP addresses are unique makes them even more valuable for collectors. 😉Seriously, IP address conflicts are a common problem in every network. There are a few things
