Cisco Discovery Protocol Configuration
Profile Network Configuration
The Cisco Discovery Protocol (CDP) is a proprietary Data Link Layer protocol implemented in Cisco
networking equipment. It's primarily used to obtain IP addresses of neighboring devices and
discover their platform information. CDP is also used to obtain information about the interfaces the
access point uses. CDP runs only over the data link layer enabling two systems that support
different network-layer protocols to learn about each other.
To define the profile’s CDP configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Network menu and select Cisco Discovery Protocol.
Enable IGMP Querier IGMP snoop querier is used to keep host memberships alive. It’s primarily used in a network
where there’s a multicast streaming server, hosts subscribed to the server and no IGMP querier
present. An IGMP querier sends out periodic IGMP query packets. Interested hosts reply with an
IGMP report packet. IGMP snooping is only conducted on wireless radios. IGMP multicast
packets are flooded on wired ports. IGMP multicast packet are not flooded on the wired port.
IGMP membership is also learnt on it and only if present, then it is forwarded on that port.
Source IP Address Define an IP address applied as the source address in the IGMP query packet. This address is
used as the default VLAN querier IP address.
IGMP Version Use the spinner control to set the IGMP version compatibility to either version 1, 2 or 3. The
default setting is 3.
Maximum Response Time Specify the maximum time (from 1 - 25 seconds) before sending a responding report. When no
reports are received from a radio, radio information is removed from the snooping table. For
IGMP reports from wired ports, reports are only forwarded to the multicast router ports. The
default setting is 10 seconds.
Other Querier Timer Expiry Specify an interval in either Seconds (60 – 300) or Minutes (1 – 5) used as a timeout interval for
other querier resources. The default setting is 1 minute.
