266 New and Enhanced Features in AlliedWare Plus 5.4.4 Major and Minor Versions
BGP4+
Border Gateway Protocol (BGP) for IPv6 is an exterior gateway protocol, often used
between gateway hosts on the Internet. It enables gateways to exchange routing
information and so to advertise, learn, and choose the best paths inside the Internet.
Software version 5.4.4 supports BGP4+ for IPv6, as well as BGP for IPv4. BGP4+ is
supported on x610 Series, x900 Series, SwitchBlade x908, and SwitchBlade x8100 Series
switches.
IPv6 Hardware ACLs
IPv6 hardware access-lists enable you to control the transmission of IPv6 packets on an
interface, and to restrict the content of routing updates.
IPv6 hardware ACLs are now available on IX5-28GPX, x510 Series, and x610 Series
switches, as well as SwitchBlade x908 and SwitchBlade x8100 Series switches.
Authentication Enhancements
Authentication now includes the following enhancements:
■ Web Authorization Proxy—enables Web Authentication to apply the supplicant’s
Web Proxy settings.
■ Two-step Authorization—improves security by authenticating both the device and
the user.
Port Flapping Detection
Port flapping detection will disable any ports that flap more than 15 times in less than 15
seconds. This limits the impact of an unreliable link.

From software version 5.4.4 onwards, AlliedWare Plus software releases are licensed.
