History
This command was introduced in ExtremeWare 6.2.2.
ip address Specifies an IP address.
all Specifies all neighbors.
number Specifies the maximum number of prefixes accepted. The range is 0 to
4294967294. A value of 0 disables prefix limit feature.
percent Specifies the percentage of the maximum prefix (threshold) at which a warning
message is printed in the log (and console), and/or a trap will be sent to the
SNMP manager.
teardown Specifies that the peer session is torn down when the maximum is exceeded.
seconds Specifies the length of time before the session is re-established. If the session
is torn down due to maximum prefix exceeded, it is kept down until the peer is
enabled. The range is 30 to 86400 seconds.
send-traps Specifies sending “number of prefix reached threshold” and “number of prefix
exceed the max-prefix limit” SNMP traps.
