JUNOSe 11.1.0 Release Notes
34
Known Behavior
On ERX routers, redundant I/O modules do not have a temperature sensor.
Therefore, the
show environment all
command output lists the primary I/O
module temperature in the slot of the line module that is responsible for the I/O
module.
When you install an ES2-S1 Redundancy IOA with a hardware revision number
of -02 or less in slot 0 or slot 11 of the E320 router or in slot 0 or the E120
router, do not install an OCx/STMx ATM IOA or an OCx/STMx POS IOA in the
lower (E320) or left (E120) adapter bay of slot 1 or slot 12. When the spare line
module is controlling another slot and you revert back to the primary line
module, the ATM or POS IOAs can become unusable or cause the line module
to reset. [Defect ID 69760]
Work-around:
This problem is not present for ES2-S1 Redundancy IOAs with a
hardware revision number of -03 or higher.
MLPPP
Do not configure both MLPPP fragmentation (with the
ppp fragmentation
command) and IP fragmentation of L2TP packets (with the
ip mtu
command)
on the same interface. Instead, you must choose only one of the fragmentation
configurations by setting it to the necessary value and set the other
fragmentation configuration to the maximum allowable value.
MPLS
Martini circuits configured on the ES2 10G LM act as true layer 2 tunnels,
without modifying the layer 2 headers. For this reason, Martini VLAN retagging
is not currently supported.
If you are upgrading to Release 7.1.0 or a higher-numbered release from a
release numbered lower than Release 7.1.0, and have inter-AS option B or C
configurations, you must explicitly configure MPLS on all inter-AS links, as in
the following example:
host1#
configure terminal
host1(config)#
interface fastEthernet 2/0
host1(config-if)#
ip address
...
host1(config-if)#
mpls
If you do not explicitly configure MPLS on the links, the inter-AS feature will not
work properly.
Multicast
The
ip dipe sg-cache-miss
and
ipv6 dipe
commands are not intended or
supported for customer use, although they are visible in the User Exec and
Privileged Exec modes respectively. These commands are intended to be used
in a Juniper Networks internal lab environment for testing without a traffic
generator.
Do not configure a multicast group with more than 10,219 outgoing interfaces
(OIFS) on the same ES2 10G LM. [Defect ID 81768]
