Known Problems and Limitations
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]
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.
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-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]
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]
When you attach certain hierarchical policies to subinterfaces as input policies,
secondary input policies, and output policies, incoming traffic loss can occur when
the number of subinterfaces to which the policies are attached exceeds 4600.
