Access Control and Security
■
When you have configured more than 1024 supplicants on a single interface,
802.1X authentication might not work as expected and the 802.1X process
(
dot1xd
) might fail.
Class of Service
■
On EX8200 switches, classification of packets using ingress firewall filter rules
with forwarding-class and loss-priority configurations does not rewrite the DSCP
or 802.1p bits. Rewriting of packets is determined by the forwarding-class and
loss-priority values set in the DSCP classifier applied on the interface.
■
On EX4200 switches, the traffic is shaped at rates above 500 kbps, even when
the shaping rate configured is less than 500 kbps.
■
When the scheduler map bound to an interface is changed, there might be packet
drops temporarily in all the interfaces bound to the scheduler map while the
configuration change is being implemented.
Firewall Filters
■
On EX Series switches, when interface ranges or VLAN ranges are used in
configuring firewall filters, egress firewall filter rules take more than 5 minutes
to take effect.
■
IGMP packets are not matched by user-configured firewall filters.
Infrastructure
■
If you configure interface parameters on an EX3200 or EX4200 switch running
JUNOS 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.
■
The RADIUS request sent by an EX Series switch contains both Extensible
Authentication Protocol (EAP) Identity Response and State attributes.
■
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.
■
Spanning-tree, GVRP, or IGMP snooping configuration windows might load slowly
in the J-Web interface. Wait till the windows load completely before entering
information, or some information might get lost.
■
On EX Series switches, the
show snmp mib walk etherMIB
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
