Resolved Issues in Junos OS Release 10.4 for EX Series Switches

Copyright © 2010, Juniper Networks, Inc.
The following are the issues that have been resolved since Junos OS Release 10.3 for EX
Series switches. The identifier following the descriptions is the tracking number in our
bug database.
NOTE: Other software issues that are common to both EX Series switches
and M, MX, and T Series routers are listed in "Issues in Junos OS Release 10.4
for M Series, MX Series, and T Series Routers" on page 48.

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.]

Firewall Filters

On EX4500 switches, if you activate or deactivate a firewall filter configuration, VSTP
convergence might not occur properly. As a workaround, restart the Ethernet switching
process ( ). [PR/548446: This issue has been resolved.]

Infrastructure

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.]
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.]
When the configured DNS server is not reachable, name resolution for
a long time and the output of the
appear. [PR/551739: This issue has been resolved.]
