SYNTAX
[no] ip igmp authentication
DEFAULT SETTING
Disabled
COMMAND MODE
Interface Configuration (Ethernet, Port Channel)
COMMAND USAGE
◆ If IGMP authentication is enabled on an interface, and a join report is
received on the interface, the switch will send an access request to the
RADIUS server to perform authentication.
◆ Only when the RADIUS server responds with an authentication success
message will the switch learn the group report. Once the group is
learned, the switch will not send an access request to the RADIUS
server when receiving the same report again within a one (1) day
period.
◆ If the RADIUS server responds that authentication failed or the timer
expires, the report will be dropped and the group will not be learned.
The entry (host MAC, port number, VLAN ID, and group IP) will be put
in the “authentication failed list”.
◆ The “authentication failed list” is valid for the period of the interval
defined by the command ip igmp snooping vlan query-interval. When
receiving the same report during this interval, the switch will not send
the access request to the RADIUS server.
