Specifications

High Availability (HA) and Resiliency
•
New redundancy failover CLI statement (M, MX, T, TX Matrix Plus)—Starting in Junos
OS Release13.3R6, the chassis redundancy failover not-on-disk-underperform statement
prevents gstatd from causing failovers in the case of slow disks on the Routing Engine.
See not-on-disk-underperform and Preventing Graceful Restart in the Case of Slow Disks.
Interfaces and Chassis
•
Validation of deactivated inline services MLPPP bundle interfaces—Starting with
Junos OS Release 13.3, if you attempt to delete or deactivate a static inline service (si)
MLPPP bundle interface that is still referenced by a member link interface, which could
be PPPoE (pp0) or silogical interfaces, and commit the configuration, the commit
operation fails. You must reactivate such MLPPP bundle interface before committing
the settings. Alternatively, you must ensure that member links do not refer a static
MLPPP bundle before you delete or deactivate the bundle. This method of deactivation
and reactivation of an MLPPP bundle is not applicable for interfaces other than si-
interfaces, such as link services IQ (lsq-) and virtual LSQ redundancy (rlsq-) interfaces.
[See Understanding MLPPP Bundles and Link Fragmentation and Interleaving (LFI) on
Serial Links.]
•
Changes to DDoS protection policers for PIM and PIMv6 (MX Series with MPCs,
T4000 with FPC5)—Starting in Junos OS Release 13.3R2, the default values for
bandwidth and burst limits have been reduced for PIM and PIMv6 aggregate policers
to prevent starvation of OSPF and other protocols in the presence of high-rate PIM
activity.
Old ValueNew ValuePolicer Limit
20,0008000Bandwidth (pps)
20,00016,000Burst (pps)
To see the default and modified values for DDoS protection packet-type policers, issue
one of the following commands:
•
show ddos-protection protocols parameters brief—Displays all packet-type policers.
•
show ddos-protection protocols protocol-group parameters brief—Displays only
packet-type policers with the specified protocol group.
An asterisk (*) indicates that a value has been modified from the default.
•
Changes to distributed denial of service statement and command syntax—Starting
in Junos OS Release 13.3R2, the protocol group and packet type syntax has changed
for the protocols statement at the [edit system ddos-protection] hierarchy level and
for the various show ddos-protection protocols commands.
The filter-v4 and filter-v6 packet types have been moved from the unclassified protocol
group to the new filter-action protocol group.
