fosExec Remote Execution
FOS v7.3 adds the ability to execute a FOS CLI command via fosExec CLI on a remote domain in the fabric.
Administrators can enable this capability to execute CLI commands on multiple switches from a single switch in
a fabric.
CS_CTL QoS Enhancements
FOS v7.3 enhances CS_CTL based QoS feature by reporting the CS_CTL auto mode in responses to device
FLOGI, FDISC, and PLOGI requests.
bottleneckMon CLI Change
FOS v7.3 deprecates the back-end credit recovery options in the bottleneckMon CLI. These options are
supported via the existing creditRecovMode CLI.
Maximum Auto Speed Negotiation
FOS v7.3 allows configuring a maximum speed for port auto speed negotiation with CLI portcfgspeed (via -m
option). Administrators can use this to control the maximum speed a device is allowed to join a fabric but still
allow port speed to be auto negotiated.

8510-4 chassis. Administrators can use this command to power on or off a core blade without physical
presence.

persistently enable the port first. Administrator can configure this option via the new portCfgPersistence
command
