JUNOS OS 10.4 Release Notes
200
Access Control and Port Security
If you connect a computer to a phone that is connected to an interface supporting
multiple supplicants on an EX2200 switch, the Telecommunications Industry
Association (TIA) network policy in the LLDP-MED packets from the EX2200 switch
reports an incorrect VLAN and the phone might lose connectivity. [PR/542810: This
issue has been resolved.]
Ethernet Switching
A LAG between an EX4200 Virtual Chassis and Cisco 6500 switch might not recover
when the EX Virtual Chassis master switch is power-cycled. [PR/505069: This issue
has been resolved.]
Hardware
EX8200 switches might not detect the front-panel LCD display. [PR/553144: This
issue has been resolved.]
After you have disabled an interface on an EX2200 switch, the LED is still lit on that
interface. [PR/553219: This issue has been resolved.]
Infrastructure
If an SRE module, RE module, SF module, line card, or Virtual Chassis member is in
offline mode, the J-Web interface might not update the dashboard image accordingly.
[PR/431441: This issue has been resolved.]
On EX Series switches, MAC addresses not present in the forwarding database (FDB)
because of hash collision are not removed from the Ethernet switching process (
These MAC addresses do not age out of the Ethernet switching table even if traffic is
stopped completely and are never relearned when traffic is sent to these MAC
addresses, even when there is no hash collision. As a workaround, clear those MAC
addresses from the Ethernet switching table. [PR/451431: This issue has been resolved.]
When multicast packets are transmitted from interfaces on which PIM is not enabled,
VRRP might flap. [PR/520194: This issue has been resolved.]
On EX8200 switches, packets with unregistered Layer 2 multicast MAC addresses are
not dropped on interfaces in the STP blocked state, resulting in some traffic loops that
might impact network performance. [PR/541123: This issue has been resolved.]
On EX2200, EX3200, EX4200, and EX4500 switches, if you configure a large number
of VLANS and aggregated Ethernet interfaces and commit the configuration, the
forwarding process (

As a result, the aggregated Ethernet interfaces cannot be used until the
reduces to normal limits. [PR/544433: This issue has been resolved.]
On EX4200 switches, spurious packets (packets with unsupported fields) arriving at
the backup Routing Engine while a GRES operation is in progress can cause a kernel
crash (
