Known Behavior

Release 11.1.1
Forwarding
z
VPLS forwarding does not function properly when any of the following conditions
occur:
−
MLPPP interfaces are used
−
L2TP is used with sequence numbers enabled
−
GRE is used with sequence numbers enabled
z
A memory leak of about two percent can occur on the ES2 10G LM and result in a
module reset when a large number of successive SRP switchovers take place with
active DHCP clients.
GRE
z
When you shut down the only outgoing IP interface to the IP destinations of GRE/IP
tunnels, the tunnels remain in the up state rather than transitioning to down. As a
consequence, all IP routes that use these tunnels as next hops also remain in the
routing table.
Hardware
z
SRP modules with only 1 GB of memory do not work reliably in ERX7xx and ERX14xx
routers running JunosE Release 8.1.0 or higher, and may experience system resets
due to an out of memory condition. However, the ERX310 router still supports 1 GB of
memory in the SRP-SE10 module.
Work-around
: Upgrade your SRP module memory to 2 GB for all ERX7xx and
ERX14xx routers running JunosE Release 8.1.0 or higher.
z
Do not include a
not
protocol
clause in any classifier control list for policies attached
to an interface on an ES2 10G Uplink LM. The
not
protocol
functionality is not
available for this module.
z
The ES2 10G LM and the ES2 10G Uplink LM do not support VLAN statistics in the
current release.
z
PCMCIA NVS Card Caution
z
The 4XOC3 APS MULTIMODE and 4XOC3 APS SINGLE MODE I/O modules are
incompatible with the following versions of the OCx/STMx ATM and OCx/STMx POS
line modules:
−
OCx/STMx ATM line modules with assembly numbers 350-00039-xx,
350-80039-xx, and 350-90039-xx
−
OCx/STMx POS line modules with assembly number 350-10039-xx
z
When you configure 1:5 line module redundancy by using either the 4XOC3 APS
MULTIMODE or 4XOC3 APS SINGLE MODE I/O module, the spare R-Mid OCX I/O
module you install must have assembly number 350-00094-01 Rev. A01 or later.
Spare R-Mid OCX I/O modules with an earlier assembly number are not supported
for 1:5 redundancy configurations that use either the 4XOC3 APS MULTIMODE or
4XOC3 APS SINGLE MODE I/O module.
Caution:
Before you insert or remove PCMCIA NVS (flash) cards from a running
router, we strongly recommend that you halt the SRP module or shut down the router.
Failure to do this can result in file corruption in one or both cards.
