portStatsShow Command Display TXQ Latency

FOS v7.4 enhances the portStatsShow CLI command to display the ASIC transmit queue (TXQ) latency
information for each virtual channel (VC).

Support De-bouncing of Loss of Signal for Fixed Speed and Auto Negotiate Ports

FOS v7.4 expands loss of signal de-bouncing for both fixed-speed and auto-negotiated ports in any port state.
FOS v7.4 adds a "mode 2" option for the portcfglosstov CLI command to enable for both fixed-speed ports and
auto-negotiate ports.

Backend Link Failure Blade Fault Option

FOS v7.4 enhances back-end link failure handling. With this enhancement, when back-end link failure is
detected, the link is re-initialized first and the blade is faulted only when re-initialization fails. In addition, a
blade would not be faulted if there is another online port within the trunk.

DLS Support on Embedded Switches

FOS v7.4 supports DLS on the embedded platforms. Earlier FOS versions do not support dynamic load sharing
(DLS) on the FC embedded platforms.

New portChannelShow CLI Command

FOS v7.4 adds a CLI command portChannelShow to display a DPS group for one or all reachable domains.

Support preserving port2area and area2port mappings with configUpload and configDownload

FOS v7.4 supports uploading and downloading the port2area and area2port mapping tables in a configuration
file for all logical switches in a chassis through the new -map option with the existing configUpload and
configDownload CLI command.
