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, traffic is shaped at rates above 500 Kbps, even when the shaping
rate configured is less than 500 Kbps.
Ethernet Switching
If you perform graceful Routing Engine switchover (GRES) on an EX4200 or an EX8200
switch, the Ethernet switching table might not refresh because the Packet Forwarding
Engine retains the forwarding database (FDB) entries. The result is that traffic is flooded
to the affected MAC addresses. As a workaround, refresh the Ethernet switching table
by issuing the
clear ethernet-switching table
Firewall Filters
On EX3200 and EX4200 switches, when interface ranges or VLAN ranges are used in
configuring firewall filters, egress firewall filter rules take more than five minutes to
install.
On EX3200 and EX4200 switches, IGMP packets are not matched by user-configured
firewall filters.
When you enable the
filter-id
of the required 802.1X authentication rules is not inserted in the IPv6 database. IPv6
traffic on the authenticated interface is not filtered; only IPv4 traffic is filtered on that
interface.
On EX8200 switches and the XRE200 External Routing Engine, if you apply different
firewall filters to different VLANs, only the filter applied to the first VLAN is applied
correctly. For example, if you issue commands to apply filter f1 to VLAN1, filter f2 to
VLAN2, and filter f3 to VLAN3, filter f1 applies correctly, but filters f2 and f3 are not
applied to any VLANs. As a workaround, merge all the VLAN filters into one single filter
and apply that filter to all the VLANs. You can use the
firewall filter terms to differentiate the rules for each of the VLANs.
Hardware
On 40-port SFP+ line cards for EX8200 switches, the LEDs on the left of the network
ports do not blink to indicate that there is link activity if you set the speed of the network
ports to 10/100/1000 Mbps. 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.
