Known Problems and Limitations

Release 11.0.2
DHCP External Server
With the unique client ID option enabled, when two clients with the same MAC
address or client ID are on an interface (where one client is connected over a
router and relay and the other client is connected directly), sending a release
request from one of the clients might terminate another client. [Defect ID
179759]
The DHCP renew counter and release counter (displayed with the
show ip
dhcp-external statistics
command) are doubled rather than incremented for
each renew and release sent. [Defect ID 78802]
When DHCP clients on an S-VLAN over bridged Ethernet stack configuration
send a decline message to a router that has DHCP relay and DHCP external
server configured in the same VR, the clients bindings are not removed from
the DHCP external server. [Defect ID 87086]
When DHCP relay and DHCP external server are configured in the same VR
with server-sync enabled, bindings are not created in the DHCP external server
when DHCP clients on an ATM bulk configuration interface stack and dynamic
VLAN over Ethernet stack sends a renew message. [Defect ID 87087]
DoS Protection
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.
Ethernet
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
File System
When the primary SRP module is running JunosE Release 7.2.0 or
higher-numbered release and the standby SRP module is running a release
numbered lower than Release 7.2.0 (as in a downgrade situation), you cannot
display the files for the standby SRP module. [Defect ID 74104]
