• Server fail fallback—Allows you to specify how 802.1X supplicants (hosts) connectedto the switch are supported if the RADIUS authentication server becomes unavailableor sends an EAPOL Access-Reject message.Bridging, VLANs, and Spanning Trees• RSTP configuration with VSTP—VSTP and RSTP can now be configured concurrently.When VSTP and RSTP are configured concurrently, the first 253 VLANs are configuredwith VSTP and the remaining VLANs are configured using RSTP. This feature allowsusers to overcome a previous restriction that only allowed VSTP to run on up to 253VLANs while no other spanning-tree protocols could run on the additional VLANs.RSTP and VSTP are the only spanning-tree protocols that can be configuredconcurrently on an J-EX Series switch.Class of Service (CoS)• Enhancements to CoS rewrite rules on J-EX8200 switches—The followingenhancements have been made to CoS rewrite rules on J-EX8200 switches:• Rewrite rules based on multifield (MF) classifiers are now supported.• Rewrite rules can now be assigned to Layer 2 interfaces, in addition to the previouslysupported Layer 3 interfaces and routed VLAN interfaces (RVIs).• Rewrite rules are now supported for switched packets.• Each interface can have different rewrite rules. You are no longer limited to a singleglobal rewrite rule for all interfaces on the switch.• Interface-specific IPv6 classifiers and rewrite rules—J-EX4200 switches now allowyou to configure and apply IPv6 classifiers and rewrite rules for each interface.Infrastructure• Enhancements to power management on J-EX8200 switches—Power managementon J-EX8200 switches now allows you to configure certain aspects of its power budgetpolicy, which determines how it manages the power supplies and allocates power tovarious components. You can:• Configure power management to manage the power supplies for N+N powerredundancy instead of N+1 redundancy.• Assign a power priority to line cards. This allows higher priority cards to receive powerwhen power is insufficient to power all line cards. Previously, when power wasinsufficient, all line cards were powered off. Now line cards receive power in priorityorder until available power is exhausted.• Distributed periodic packet management—The responsibility for PPM processing onan J-EX Series switch is now distributed between the Routing Engine and either theaccess interfaces (on J-EX4200 switches) or the line cards (on J-EX8200 switches)by default. PPM previously ran solely on the Routing Engine. We recommend that you4JUNOS 10.2 Software Release Notes
