What’s New in this Release
This release includes the following new features and updates:
• Internet Small Computer System Interface (iSCSI) traffic optimization—
Applies a specific service profile to iSCSI flows that are received on device
interfaces. This functionality provides the ability to prioritize and “mark” this
traffic according to a user definition. The switch detects iSCSI flows, as
defined by a user, and assigns these flows with defined VPT, DSCP, and
queue settings. iSCSI is identified by the TCP port on which iSCSI targets
listen-to requests, and optionally by the IPv4 address on which iSCSI
targets listen-to requests.
• IP SLA object tracking for VRRP—A mechanism that uses SLA operations to
track the connectivity to VRRP master router default route next hop. If
connectivity to NH is lost, master router VRRP priority is decremented,
which allows backup routers with a priority that is higher than the
decremented value to take over and become the master router. This
functionality allows connectivity to NH via the new selected master router.
This mechanism is needed when using static routing, but not when using
RIP or another dynamic routing protocol.
• SSL enhancements—Including upgrade to OpenSSL to version 1.0.1.s,
removal of weak ciphers (less than 64 bits and export ciphers), and removal
of support for SSLv3 and TLSv1.0.
• Single image support —The same software image file is used for all
devices that support this software release. (In previous releases, there were
two separate software images, one for the SG550XG and SG350XG
devices and one for other SKU types.)
• Hybrid stack mode support—Supports the deployment of Sx350X devices
with SG350XG devices in the same stack, and the deployment of Sx550X
