Multicast enhancement
Description
The BigIron RX supports IGMP snooping.
Security enhancements
Description
Multi-device port authentication is now supported on
the BigIron RX.
This release allows you to enable 802.1X port
security and multi-device port authentication on the
same interface.
With this release, you can configure deny mac
addresses on a global level or on a per port level.
Fragmented IP packets with undersized fragments
and overlapping fragments are dropped.
Packets with IP options in their header are
automatically dropped. Enabling the ip
ip-option-process command allows the device to
process packets that use IP options.
You can use IPv4 ACLs to filter the packets intended
for the management processor to protect the
management module from being overloaded with
heavy traffic that was sent to one of the Layer 3
Switch IP interfaces.
Static routes can be configured with tag values.
