Parameters
ipv6: Limits the number of IPv6 source guard binding entries. Without this keyword, the command limits
the number of IPv4 source guard binding entries.
number: Specifies the maximum number of IP source guard entries allowed on the port, in the range of
0 to 256 for IPv4, or in the range of 0 to 256 for IPv6.
Description
Use the ip check source max-entries command to limit the total number of static and dynamic IPv4 (or
IPv6) source guard binding entries on a port. When the number of IPv4 (or IPv6) binding entries on a
port reaches the maximum, the port does not allowed new IPv4 (or IPv6) binding entries any more.
Use the undo ip check source max-entries command to restore the default.
