JUNOSe 10.2.2 Release Notes
26
Known Behavior
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. The configuration of the multicast group’s OIF
membership from the SRP module to the line module exceeds the size of a
single message and is sent in fragments. Because of this fragmentation, the ES2
10G LM generates the following error message: [Defect ID 81768]
pc: 0x9e5c88: -> fatalPanic(void) offset: 0x8
Packet Mirroring
The ES2 10G LM supports the packet mirroring feature when the module is
paired with the ES2-S2 10GE PR IOA, the ES2-S1 GE-8 IOA, or the ES2-S3 GE-20
IOA. When you use the ES2 10G LM with these IOAs, CLI-based
interface-specific mirroring is not supported.
