Limitations in Junos OS Release 10.3 for J-EX Series Ethernet Switches

This section lists the limitations in Junos OS Release 10.3R2 for J-EX Series Ethernet

switches.

Access Control and Port 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.

•

The RADIUS request sent by a J-EX Series Ethernet 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

authd

daemon

is restarted. As a workaround, configure the revert interval—the time after which to

revert to the primary server—and restart the

authd

daemon.

Bridging, VLANs, and Spanning Trees

•

On J-EX Series Ethernet 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
