On EX4500 switches, if you activate and then deactivate a firewall filter configuration,
VSTP convergence might not occur properly. As a workaround, restart the Ethernet
switching process (

On an interface that is receiving storm traffic, if you use the
ethernet-switching-options storm-control action-shutdown
interface, it can take up to 30 seconds for the interface to shut down. [PR/556107]
Firewall Filters
On EX4200 switches, if you configure a firewall filter with the match condition
, the error message "not supported" is displayed. [PR/543316]

Hardware
On EX4200 switches, the uplink port status LED on the 4-port Gigabit Ethernet SFP
does not properly indicate the status of the uplink port. [PR/528070]
If no Intraconnect module or Virtual Chassis module is installed in EX4500 switches,
the switch boots but is not fully functional. Traffic loss can occur during packet
forwarding. [PR/544628]
Infrastructure
On EX8200 switches, when IGMP snooping is enabled on an interface, the IPv6
multicast Layer 2 control frame is not forwarded to other interfaces in the same VLAN.
The result is that IPv6 and VRRP for IPv6 neighbor solicitation fails. [PR/456700]
On EX8200 switches, when you perform a graceful Routing Engine switchover (GRES)
or when you restart Ethernet switching on any spanning-tree protocol domain, a loop
might occur. [PR/516611]

On EX4200 switches, the SFP+ uplink module might not work correctly even though
the link status is UP. [PR/569307]
On EX4500 switches, if more than 14 ports in the switch are subscribed to a 10-gigabit
full-duplex rate of traffic, the switch might not be able to achieve a 10-gigabit wire rate
for 64 and 128 byte packets. There is no impact on performance if the number of ports
actively involved in 10-gigabit wire-rate traffic is 14 or fewer or if the packet size is
greater than 150 bytes. [PR/573319]
