Known Problems and Limitations
45
Release 11.1.1
z
The OC3/STM1 GE/FE line module might reset after sending Ethernet traffic into a
VPLS network in a test environment when Ethernet packets are flooded to remote
VPLS bridges. [Defect ID 74540]
Policy Management
z
On the E320 router, redirecting a large configuration with thousands of interfaces to
a script file can take a long time, perhaps exceeding a half-hour depending on the
configuration. [Defect ID 80429]
z
If you have removed the last rule in a policy list, the router generates a warning only
after you exit Policy List Configuration mode. If you have removed the last policy rule
and then added a classifier group before you exit Policy List Configuration mode, the
router does not generate a warning about removing the last rule. [Defect ID 83834]
z
When an MD-Port-Number value greater than 65,535 is sent to an E120 or E320
router by means of a COA request, the value that is displayed in the UDP header of
mirrored packets is the actual value minus 65,536. For example, an MD-Port-Number
of 65,540 is displayed in the mirrored packet as 4. [Defect ID 84712]
z
On the E120 and E320 routers, when a mirror rule is deleted after a CoA request is
sent with Juniper-LI-Action set to No-Action, the existing mirroring session is not
disabled. [Defect ID 84826]
z
When you reload the slot holding a GE-2 or GE-HDE line module and you have
configured more than about 2000 policies with rate limiting on that module, the drop
count becomes more than expected. This unexpected drop count does not occur
when you create the same configuration after you reload the router to the
factory-default configuration. [Defect ID 175696]
z
On E320 line modules that support secure policies, the SRP module enables you to
configure more than 1022 secure policies per module. [Defect ID 175756]
Work-around
: To avoid potential performance issues, we recommend that you do
not configure more than 1022 secure policies per module.
z
Unified in-service software upgrade (unified ISSU) is not supported on an E120 or
E320 router if a hierarchical policy is attached to an external parent group. [Defect ID
177478]
z
When you modify a rate-limit profile in Global Configuration mode after the system is
in a scaled state, changes to the rate-limit profile fail owing to lack of adequate
policy resources. However, the changed value of the rate-limit profile is displayed in
the output of the
show rate-limit profile
command. [Defect ID 79342]
Work-around
: To avoid this problem, do not update the rate-limit profile in Global
Configuration mode in a scaled environment.
z
When you enter the
no ip policy-parameter hierarchical parameterName
command
or
no ipv6 policy-parameter hierarchical parameterName
command for a
hierarchical policy-parameter type in Interface Configuration mode, the explicit
reference of the parameter is removed successfully from the interface. However, the
Referenced by interfaces field in the output of the
show policy-parameter
command
does not change from the previously configured value to implicit. [Defect ID 183957]
Work-around
: To correct this problem, remove the entire interface configuration.
