New Features in Version 4.1.4



Beta Support For Multicast Tunneling

Version 4.1.4 continues beta support for multicasting over unicast tunnels.
Version 4.1.4 adds the mrinfo utility.  This utility displays configuration
information from a multicast router.  The utility can be used to display
multicast neighbors, metrics, thresholds, flags and other additional
information. Support for this feature is BETA ONLY.  A fully integrated
configuration and extended compliance testing will be completed prior to full
release in a future version. Customers requiring this functionality should
contact ImageStream Support by e-mail at support@imagestream.com for further
guidance. 


Various Aesthetic Changes To Update Utility

The update utility used in conjunction with Version 4.1.4 and all other updates
as of this release has been updated.  The update utility disables manual reboot
and halt options during an update, and adds additional debugging information.   



Bugs fixed in Version 4.1.4


The following bugs have been fixed in Version 4.1.4:


Lengthy Speed/Duplex Autonegotation With Certain Ethernet Hubs Fixed

Version 4.1.4 adds a new version of the MII diagnostic utility used to set link
speed and duplex.  The version used with 4.1.3 contained a bug that would cause
some hubs that did not support 100 Mbps full duplex operations to take up to 40
seconds to autonegotiate.  The MII diagnostic utility used in Version 4.1.4
supports additional autonegotiation parameters that eliminate this delay.


Ethernet Hardware Status Follows Autonegotiation Instead Of Link Status Fixed

Under previous Version 4.x releases, Ethernet devices using forced link speed or
duplex would display hardware down in the interface statistics utility. Version
4.1.4 correctly sets hardware status according to the link status of the
Ethernet device.  This bug only affected the display of Ethernet devices in the
interface statistics utility and does not affect the operation of Ethernet
devices.


Removing CIPE Tunnel Interface Does Not Shut Down Tunnel Problem Corrected

The Version 4.1.3 release did not properly shut down CIPE tunnel interfaces when
the interface was removed from wan.conf.  Existing tunnels could only be shut
down by inserting a shutdown command. Version 4.1.4 correctly checks for the   
removal of CIPE tunnel interfaces from wan.conf and disables removed interfaces
accordingly.
