auto-detect
This command enables automatic validation of dynamic user binding table
entries by periodically sending NS messages and awaiting NA replies. Use
the no form to disable this feature.
SYNTAX
[no] ipv6 nd snooping auto-detect
DEFAULT SETTING
Disabled
COMMAND MODE
Global Configuration
COMMAND USAGE
If auto-detection is enabled, the switch periodically sends an NS message
to determine is a client listed in the dynamic binding table still exists. If it
does not receive an RA message in response after the configured timeout,
the entry is dropped. If the switch receives an RA message before the
timeout expires, it resets the lifetime for the dynamic binding, and the
auto-detection process resumes.
EXAMPLE
Console(config)#ipv6 nd snooping auto-detect
Console(config)#
ipv6 nd snooping
auto-detect
retransmit count
This command sets the number of times the auto-detection process sends
an NS message to determine if a dynamic user binding is still valid. Use the
no form to restore the default setting.
SYNTAX

determine if a client still exists. (Range: 1-5)
