Hardware
•
On 40-port SFP+ line cards for EX8200 switches, the LEDs on the left of the network
ports blink to indicate that there is link activity. If you set the speed of the network ports
to 10/100/1000 Mbps, the LEDs do not blink. However, if you set the speed to 10 Gbps,
the LEDs blink.
•
If you press the reset button on the Switch Fabric and Routing Engine (SRE) module
in an EX8208 switch without taking the module offline first (by using the CLI), the
fabric planes in the module might not come back online.
•
On 40-port SFP+ line cards installed in EX8200 switches, it takes about 10 seconds
for the network ports to come up after you reboot the switch or restart the line card.
High Availability
•
On EX8216 switches on which nonstop active routing (NSR) is configured, after a
graceful Routing Engine switchover (GRES), the routing protocol process (rpd) might
be delayed while state replication finishes. The length of delay depends on the scale
of the setup. During this delay, operational mode commands for the rpd process do
not provide current information.
Infrastructure
•
If you configure interface parameters on an EX3200 or EX4200 switch running Junos
OS Release 9.2 or Release 9.3 for EX Series switches and then attempt to upgrade to
a later release or a later version of Release 9.3 than the one that is currently installed,
the switch might display the following error message: “init: interface-control is thrashing
, not restarted”. As a workaround, on the interfaces you had previously configured,
configure no-auto-negotiation and set the link mode to full-duplex, then commit the
revised configuration.
•
On EX Series switches, an SNMP query fails when the SNMP index size of a table is
greater than 128 bytes, because the Net SNMP tool does not support SNMP index sizes
greater than 128 bytes.
•
On EX Series switches, the show snmp mib walk etherMIB command does not display
any output, even though the etherMIB is supported. This occurs because the values
are not populated at the module level—they are populated at the table level only. You
can issue show snmp mib walk dot3StatsTable, show snmp mib walk dot3PauseTable,
and show snmp mib walk dot3ControlTable commands to display the output at the
table level.
•
When you issue the request system power-off command, the switch halts instead of
turning off power.
•
In the J-Web interface, the Ethernet Switching monitoring page might not display
monitoring details if there are more than 13,000 MAC entries on the switch.
•
In the J-Web interface, changing the port role from Desktop, Desktop and Phone, or
Layer 2 Uplink to another port role might not remove the configurations for enabling
dynamic ARP inspection and DHCP snooping.
