Known Problems and Limitations
A Telnet session closes when sending ipLocalBGP protocol traffic at a rate in the
range 4096–4200 packets per second (pps) with suspicious control flow
detection enabled. [Defect ID 81974]
Work-around: When the traffic drops below 4096 pps, open a new Telnet
session.
The DoS protection egress rate is not accurate for the ES2 10G LM or the ES2
10G Uplink LM. [Defect ID 86925]
When autonegotiation is enabled on Gigabit Ethernet interfaces with the speed
automatically negotiate command, issuing the link selection command logs
out subscribers. [Defect ID 87185]
Work-around: Use the following commands to enable auto link selection (GE
port redundancy) and to switch from one port to the other port:
(config-if)#no link selection
(config-if)#link failover force
When the primary SRP module is running JUNOSe Release 7.2.0 or higher and
the standby SRP module is running a release lower than Release 7.2.0 (as in a
downgrade situation), you cannot display the files for the standby SRP module.
[Defect ID 74104]
When performing MAC validation to match subscriber demux entries with ARP
host entries, the ES2 10G LM does an exact match, rather than a longest prefix
match. The subscriber demux entry source address must be a /32 value
matching the IP address of an ARP entry in order to validate the MAC address
against that ARP entry. [Defect ID 79641]
VPLS forwarding does not function properly when any of the following
conditions occur: [Defect ID 79856]
MLPPP interfaces are used
L2TP is used with sequence numbers enabled
GRE is used with sequence numbers enabled
When PPPoE over LAG is configured on an interface, and you re-execute the
PPPoE-over-LAG configuration before you delete the previous configuration, the
ES2 10G LM line module resets. [Defect ID 179639]
Work-around: Before you can re-execute the PPPoE-over-LAG configuration,
delete the existing PPPoE-over-LAG configuration.
