System enhancements (Continued)
Description
You can configure the BigIron RX to monitor XFPs and SFPs in
the system either globally or by specified port.
In releases prior to 02.3.00, CAM partitioning was not
configurable. Starting in BigIron RX software release 02.3.00,
you can specify the CAM assigned to each of the CAM entry
types globally.
You can disable power to a specified switch fabric module and
then reenable it.
In this release, the speed-duplex command has been
enhanced to include the master and slave parameters.
Layer 2 enhancements
Description
In this release, the cpu-flooding unknown-unicast
command that disables hardware flooding of
unknown unicast on every VLAN has been added.
This will allow MAC learning only where necessary
and at a system level to allow more than 16k MACs.
This feature allows for a hold down time before the
backup returns ownership to the master after the
link is seen.
With this release, you can configure multiple STP
instances using MSTP protocol, as defined in IEEE
802.1s
