Limitations in Junos OS Release 10.3 for J-EX Series Ethernet Switches bits. Rewriting of packets is determined by the forwarding-class and loss-priority values set in the DSCP classifier applied on the interface. • On J-EX4200 switches, the traffic is shaped at rates above 500 Kbps, even when the shaping rate configured is less than 500 Kbps. Firewall Filters • On J-EX4200 switches, when interface ranges or VLAN ranges are used in configuring firewall filters, egress firewall filter rules take more than 5 minutes to install. • On J-EX4200 switches, IGMP packets are not matched by user-configured firewall filters. Hardware • If you press the reset button on the Switch Fabric and Routing Engine (SRE) module in a J-EX8208 switch without taking the module offline first (using the CLI), the fabric planes in the module might not come back online. Infrastructure • On J-EX Series Ethernet 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 J-EX Series Ethernet 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. • On J-EX8200 switches, if IS-IS is enabled on routed VLAN interfaces (RVIs), IS-IS adjacency states go down and come up after a graceful Routing Engine switchover (GRES). • Momentary loss of an inter-Routing Engine IPC message might trigger the alarm that displays the message Loss of communication with Backup RE. There is no functionality affected. 55

bits. Rewriting of packets is determined by the forwarding-class and loss-priority values
set in the DSCP classifier applied on the interface.
•
On J-EX4200 switches, the traffic is shaped at rates above 500 Kbps, even when the
shaping rate configured is less than 500 Kbps.
Firewall Filters
•
On J-EX4200 switches, when interface ranges or VLAN ranges are used in configuring
firewall filters, egress firewall filter rules take more than 5 minutes to install.
•
On J-EX4200 switches, IGMP packets are not matched by user-configured firewall
filters.
Hardware
•
If you press the reset button on the Switch Fabric and Routing Engine (SRE) module
in a J-EX8208 switch without taking the module offline first (using the CLI), the fabric
planes in the module might not come back online.
Infrastructure
•
On J-EX Series Ethernet 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 J-EX Series Ethernet 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.
•
On J-EX8200 switches, if IS-IS is enabled on routed VLAN interfaces (RVIs), IS-IS
adjacency states go down and come up after a graceful Routing Engine switchover
(GRES).
•
Momentary loss of an inter-Routing Engine IPC message might trigger the alarm that
displays the message
Loss of communication with Backup RE
. There is no functionality
affected.
