Specifications

•
PCS statistics counter is now displayed for PTX 100GE interfaces in the following: cli
> monitor interface <intf> PR1030819
Infrastructure
•
SNMP socket sequence error log. PR986613
Interfaces and Chassis
•
Interface statistic information is wrong for IPV6. This is expected behavior because
ipv6 transit stat is not supported yet. PR965360
•
On PTX Series platform, CFP-100G-LR4 and CFP2-100G-LR4 optics report incorrect
"Laser output power" values on all four lanes in cli > show interface diagnostics optics
<intf>. PR1021541
MPLS
•
When a PTX Series router is at the merge-point (MP) of a bypass LSP, if MPLS
explicit-null has been enabled on the router, and the loopback interface has not been
configured under protocol RSVP, the bypass LSP might not work correctly. PR1012221
•
On P2MP MPLS LSP transit router with NSR enabled, when RSVP refresh reduction
feature is enabled and LSP link protection is configured on all interfaces, slight P2MP
traffic loss might be seen after the graceful Routing Engine switchover (GRES) is done.
PR1023393
Layer 2 Features
•
The PTX Series router is not supposed to generate pause frames even if it gets
congestion. The behavior is to drop aggressively if it ever runs out of queuing memory.
run out case. PR968803
Routing Protocols
•
Establish two BFD sessions between two routers, one is single-hop BFD for directly
connected interface and the other is multi-hop MPLS OAM BFD. If configuring the
MPLS OAM on the same interface with single-hop BFD, when bringing down MPLS
OAM from the ingress, it might result in the OAM BFD session deleted on ingress but
it still receiving OAM BFD down packet from egress. Since there is no session matching
this BFD packet, it does a normal look up and brings down the single-hop BFD session
which is on the same interface. PR1021287
Resolved Issues: Release 13.3R4
General Routing
•
On PTX Series routers with AE interface, when the PTX is in ingress node for P2MP
LSP, the double traffic rate might be seen. PR987005
•
When a large number of IGMP join packets try to reach the router, some IGMP packets
might get dropped. PR1007057
