Specifications

•
On an EX9200 switch that works as a DHCP relay agent, if the switch receives broadcast
DHCP ACK packets sent by another DHCP relay switch, those packets might be dropped
until the DHCP max-hop limit is reached. PR961520
Infrastructure
•
On EX9200 switches with an EX9200-32XS line card or an EX9200-2C-8XS line card,
10-gigabit ports on the line card might stay offline if a link flaps or an SFP+ is inserted
after the links have been up for more than 3 months. PR905589
•
On an EX Series Virtual Chassis that is configured for DHCP services and configured
with a DHCP server, when a client sends DHCP INFORM packets and then the same
client sends the DHCP RELEASE packet, an IP address conflict might result because
the same IP address has been assigned to two clients. As a workaround:
•
1. Clear the binding table:
user@switch> clear system services dhcp binding
•
2. Restart the DHCP service:
user@switch> restart dhcp

•
On an EX9200 switch, when the SNMP mib2d daemon polls system statistics from
the kernel, the kernel might cause a memory leak (mbuf leak), which in turn might
cause packets such as ARP packets to be dropped at the kernel. PR953664
•
On an EX9200 switch with scaled ARP entries (for example, 48K entries), in a normal
state, an ARP entry's current time must be less than the expiry time. However, some
events might cause the current time to be greater than the expiry time, which then
leads to the ARP entry being flushed, resulting in connectivity issues. A possible trigger
event might be an Inter-Chassis Link flap in a multichassis link aggregation group
scenario. PR963588
Interfaces and Chassis
•
On EX9200 switches, an inter-IRB route might not work if Q-in-Q tunneling is enabled,
because the TPID (0x9100) is not set on egress dual-tagged packets, and other devices
that receive these untagged packets might drop them. PR942124
•
On an EX Series switch, if you remove an SFP+ and then add it back or reboot the
switch, and the corresponding disabled 10-gigabit interface is a member of a LAG, the
link on that port might be activated. PR947683
Virtual Chassis
•
On EX9200 Virtual Chassis, the show virtual-chassis vc-port command shows a resync
flag as part of the Status column of the command. The resync flag indicates the
forwarding readiness of the Packet Forwarding Engine (on which VCPs are configured),
after it is up after a reboot. PR946920
