Junos 10.3 OS Release Notes for more than 60 minutes. As a result, the aggregated Ethernet interfaces cannot be used until the pfem usage reduces to normal limits. [PR/544433] • When an IGMP version 3 group-specific report is sent to a VLAN in a J-EX4200 switch, the switch sends back the Group and Source-Specific Queries (GSSQ) message to the intended receivers only, instead of flooding the message to all members of that VLAN. This problem occurs because the switch uses the standard forwarding database (FDB) lookup scheme to send out the GSSQ message and does not flood the VLAN. [PR/560945] • On J-EX8200 switches, the routing protocol process might crash because some PIM-enabled interfaces are reusing SNMP indexes, which disables interfaces and IPv6 routing instances. [PR/561042] Interfaces • On J-EX8200 switches, aggregated Ethernet interfaces might go down and come back up for a few minutes while the switch is updating many routes. [PR/416976] • On J-EX8200 switches, when a firewall filter is applied on the loopback (lo0) interface, the switch stops generating local ARP requests for transit traffic. As a workaround, do the following: • Create firewall filters to block known unwanted traffic to the Routing Engine, and then accept all other traffic. • Create firewall filters for specific hosts and all local subnets, and then discard all other traffic. [PR/486443] J-Web Interface • In the J-Web interface, you cannot commit some configuration changes in the Ports Configuration page and the VLAN Configuration page because of the following limitations for port mirroring ports and port mirroring VLANs: • A port configured as the output port for an analyzer cannot be a member of any VLAN other than the default VLAN. • A VLAN configured to receive analyzer output can be associated with only one port. [PR/400814] • J-Web does not provide a way to upload a Junos OS package to the backup Routing Engine. As a workaround, use the CLI command request system software add to upload Junos OS packages to the switch. For details, see "Installing Software on a J-EX8200 Switch with Redundant Routing Engines (CLI Procedure)" in the Dell PowerConnect J-Series Ethernet Switch Complete Software Guide for Junos OS Release 10.3. [PR/402109] • If an SRE module, RE module, SF module, line card, or Virtual Chassis member is in offline mode, the J-Web interface might not update the dashboard image accordingly. [PR/431441] 58

for more than 60 minutes. As a result, the aggregated Ethernet interfaces cannot be
used until the
pfem
usage reduces to normal limits. [PR/544433]
•
When an IGMP version 3 group-specific report is sent to a VLAN in a J-EX4200 switch,
the switch sends back the Group and Source-Specific Queries (GSSQ) message to
the intended receivers only, instead of flooding the message to all members of that
VLAN. This problem occurs because the switch uses the standard forwarding database
(FDB) lookup scheme to send out the GSSQ message and does not flood the VLAN.
[PR/560945]
•
On J-EX8200 switches, the routing protocol process might crash because some
PIM-enabled interfaces are reusing SNMP indexes, which disables interfaces and IPv6
routing instances. [PR/561042]
Interfaces
•
On J-EX8200 switches, aggregated Ethernet interfaces might go down and come back
up for a few minutes while the switch is updating many routes. [PR/416976]
•
On J-EX8200 switches, when a firewall filter is applied on the loopback (
lo0
) interface,
the switch stops generating local ARP requests for transit traffic. As a workaround, do
the following:
•
Create firewall filters to block known unwanted traffic to the Routing Engine, and
then accept all other traffic.
•
Create firewall filters for specific hosts and all local subnets, and then discard all
other traffic.
[PR/486443]
J-Web Interface
•
In the J-Web interface, you cannot commit some configuration changes in the Ports
Configuration page and the VLAN Configuration page because of the following
limitations for port mirroring ports and port mirroring VLANs:
•
A port configured as the output port for an analyzer cannot be a member of any
VLAN other than the default VLAN.
•
A VLAN configured to receive analyzer output can be associated with only one port.
[PR/400814]
•
J-Web does not provide a way to upload a Junos OS package to the backup Routing
Engine. As a workaround, use the CLI command
request system software
add to upload
Junos OS packages to the switch. For details, see “Installing Software on a J-EX8200
Switch with Redundant Routing Engines (CLI Procedure)” in the
Dell PowerConnect
J-Series Ethernet Switch Complete Software Guide for Junos OS Release 10.3.
[PR/402109]
•
If an SRE module, RE module, SF module, line card, or Virtual Chassis member is in
offline mode, the J-Web interface might not update the dashboard image accordingly.
