Miscellaneous Enhancements

Credit Recovery Support on F_Ports to Brocade HBA

FOS v7.1 implements credit recovery mechanisms on F_Ports connecting to Brocade 8G or 16G HBAs.

Credit Recovery alert to the User Level RASlog

FOS v7.1 adds a user level RASlog Cxx_1023 to alert about buffer credit recovery performed on 16G FC

platforms. This RASlog is generated whenever a single credit loss was detected and automatically recovered.

This RASlog can be viewed by using the errDump command.

Virtual Fabrics: Set Logical Switch Context Using Switch Name

In pre-FOS v7.1, in the Virtual Fabrics environment, when switching context between Logical Switches within a

physical switch, the FID number is required to set the context of a logical switch. In FOS v7.1 this setcontext CLI

has been enhanced to allow “switch name” to set the Logical Switch context.

Fabretrystats CLI

With FOS v7.1 a new command fabRetryStats has been implemented that not only includes functionality

equivalent to fabRetryShow (via –show option), but also implements additional functionality to clear any retry

counters of fabric SW_ILS commands.

Display of WWNN on Segmented ISLs

FOS v7.1 has been enhanced to display the WWN details of the neighbor switch in switchShow and islShow

command outputs when an ISL gets segmented. Please note that if the very first ELP (Exchange Link

Parameters) fails between neighboring ports then the WWNN may not be displayed at both ends of the

segmented link.

TI (Traffic Isolation) Zone Violation Handling for Trunk Ports

If a failover disabled TI zone has trunk members, but if not all members of that trunk group are in the same TI

zone, then there is a possibility of routing issues if the members in the TI zone fail. FOS v7.1 tries to detect

such mis-configurations upfront and warn users about this condition via the ZONE_1061 RASlog message.

Add Support for switchCfgPersistentDisable –set option

In pre-FOS v7.1, on executing the switchCfgPersistentDisable command, the switch is disabled immediately.

However, this may not be the desired behavior all the time. Hence in FOS v7.1 a new option has been added to

just set the switch to disable state and not actually disable the switch immediately. If the switch is

subsequently disabled or reboots, it will be held in the disabled state.

portAutoDisable Enhancements

FOS v7.1 adds the following options to portAutoDisable command:

1) “portcfgautodisable --suspend”

When this command is issued all the existing configurations will not be disturbed but no action will be

performed on the port for the configured options (i.e. option = LOSG, OLS, NOS, LIP,LOSN) .

2) “portcfgautodisable --resume”

For the configured option the action will be performed. Here the action means for the existing configured

option (i.e. option = LOSG, OLS, NOS, LIP, LOSN) the port gets auto disabled.

portnumbers in Hexadecimal Format

The commands portDisable, portEnable, portShow, portPerfShow, portCfgSpeed, portStatsClear, and

portStatsShow can accept port numbers in hexadecimal format.

“–x” option indicates that a port or a range of ports identified by port index numbers is in hex format.

CS_CTL based QoS Related Enhancements

FOS v7.1 provides an additional option to the end users to map CS_CTL values to QoS traffic priorities. Starting

with FOS v7.1, users have the choice to map CS_CTL values of 1, 2 and 3 to QoS priorities Low, Medium and

High respectively.
