IGMP Profile Configuration
Mode Commands
The Internet
Group Management Protocol (IGMP) Profile Configuration Mode is used
to create and manage the IGMP parameters for an Ethernet interface.
IMPORTANT:
Available commands
or keywords/variables vary based on platform type, product
version, and installed license(s).
default ip igmp
Configures default
IGMP parameters.
Privilege:
Security Administrator,
Administrator
Syntax
default ip igmp { query | require | robustness | unsolicited-report-interval | version }
Usage:
Specify the IGMP parameters
for the default profile. Refer to the remaining command description
in this chapter for additional information.
Example:
To apply enable echo
mode on this interface, use the following command:
bfd echo
ip igmp query
Configures the maximum
response time for IGMP queries.
Privilege:
Security Administrator,
Administrator
Syntax
ip igmp query max-response-time seconds
max-response-time seconds:
Specify the maximum
number of seconds that the system will wait for an IGMP response as
an integer from 1 through 25.
Usage:
Specify the maximum
response time for IGMP queries.
Example:
ip igmp query max-response-time 10
ip igmp require
router-alert
Sets the router alert
flag to ON in IP IGMP packets.
Privilege:
Security Administrator,
Administrator
Syntax
[ no ] ip
igmp require router-alert
Sets the router alert
flag to OFF in IP IGMP packets.
Usage:
Sets the router alert
flag to ON in IP IGMP packets.
Example:
ip igmp require router-alert
ip igmp robustness
Sets the Robustness
value in IP IGMP packets. The Robustness variable allows tuning
for the expected packet loss on a subnet. If a subnet is expected
to be lossy, the Robustness variable may be increased. IGMP is robust
to packet losses. The Robustness variable should not be set to 1
(one).
Privilege:
Security Administrator,
Administrator
Syntax
ip igmp robustness value
Sets the robustness
value as an integer from 1 through 10. Default: 2
Usage:
Sets the robustness
value in IP IGMP packets.
ip igmp unsolicited-report-interval
Sets the Unsolicited
Report Interval which is the time between repetitions of a host's
initial report of membership in a group.
Privilege:
Security Administrator,
Administrator
Syntax
ip igmp unsolicited-report-interval seconds
Specifies the number
of seconds between repetitions of a host's initial report of membership
in a group as an integer from 1 through 25. Default: 10
Usage:
Set the Unsolicited
Report Interval which is the time between repetitions of a host's
initial report of membership in a group.
Example:
ip igmp unsolicited-report-interval 15
ip igmp version
Sets the IGMP version
to be supported by this interface.
Privilege:
Security Administrator,
Administrator
Syntax
ip igmp version { v1 | v2 | v3 }
Specifies the IGMP
Version number:
- v1: Version 1, RFC
1112
- v2: Version 2, RFC 2236
- v3: Version 3, RFC 4604
Usage:
Set the IGMP version
to be supported by this interface.
