The RADIUS request sent by a J-EX Series switch contains both Extensible
Authentication Protocol (EAP) Identity Response and State attributes.
When an external RADIUS server goes offline and comes back online after some time,
subsequent captive portal authentication requests might fail until the
is restarted. As a workaround, you can configure the revert interval—the time after
which to revert to the primary server—and restart the
Bridging, VLANs, and Spanning Trees
On J-EX Series switches, configuring more than 64,000 MAC address clone routes in
a single VLAN causes the Routing Engine to create core files and reboot.
Class of Service
On J-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 J-EX4200 switches, the traffic is shaped at rates above 500 Kbps, even when the
shaping rate configured is less than 500 Kbps. The minimum shaping rate is 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.
Infrastructure
On J-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.

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.
