Example
The following command configures the maximum number of IP prefixes accepted from the peer group
outer to 5000, sets the threshold for warning messages to 60%, and specifies SNMP traps:
configure bgp peer-group outer maximum-prefix 5000 threshold 60 send-traps
History
This command was introduced in ExtremeWare 6.2.2.
name Specifies a peer group.
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 on the console). An SNMP trap can also be
sent.
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
has been torn down due to exceeding the max limit, 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.
