Target rate limiting settings (HBA) 3 • Use the following command to determine operating speed of the remote port and QoS status. rport --query [-l ] where: port_id rpwwn -l lpwwn Specifies the ID of the port for which you want to query attributes of a remote port. Remote PWWN. You can obtain the RPWWN from the BCU rport --list command. Logical PWWN. This is an optional argument. If the -l lpwwn argument is not specified, the base port is used. Determining QoS settings through HCM Use HCM in the following ways to determine current status and configuration for QoS: • Use the Port Properties panel in HCM to display configured QoS parameters. 1. Select a port in the device tree. 2. Click the Properties tab in the right pane. The Port Properties panel displays • Use the Remote Port Properties panel in HCM to display information on QoS for the remote port. 1. From the device tree, select a remote port (target or initiator). 2. Click the Remote Port Properties tab in the right pane. The Remote Port Properties panel displays. Target rate limiting settings (HBA) Display target rate limiting settings on HBA ports or Fabric Adapter ports configured in HBA mode. Target rate limiting throttles the Fibre Channel Protocol (FCP) read traffic rate to slow-draining targets to reduce or eliminate network congestion and alleviate I/O slowdowns to faster targets. Use the following BCU commands to determine current status and configuration for target rate limiting settings: Determining target rate limiting settings through BCU Use the following BCU commands to determine current status and configuration for target rate limiting settings: • Use the following BCU command to determine target rate limiting speed and enabled status. ratelim --query where: Brocade Adapters Troubleshooting Guide 107 53-1002145-01

•
Use the following command to determine operating speed of the remote port and QoS status.
rport --query <port_id> <rpwwn> [-l <lpwwn>]
where:
port_id
Specifies the ID of the port for which you want to query attributes of a remote
port.
rpwwn
Remote PWWN. You can obtain the RPWWN from the BCU rport --list
<port_id> command.
-l lpwwn
Logical PWWN. This is an optional argument. If the -l lpwwn argument is not
specified, the base port is used.
Determining QoS settings through HCM
Use HCM in the following ways to determine current status and configuration for QoS:
•
Use the
Port Properties
panel in HCM to display configured QoS parameters.
1.
Select a port in the device tree.
2.
Click the
Properties
tab in the right pane.
The
Port Properties
panel displays
•
Use the
Remote Port Properties
panel in HCM to display information on QoS for the remote
port.
1.
From the device tree, select a remote port (target or initiator).
2.
Click the
Remote Port Properties
tab in the right pane.
The
Remote Port Properties
panel displays.
Target rate limiting settings (HBA)
Display target rate limiting settings on HBA ports or Fabric Adapter ports configured in HBA mode.
Target rate limiting throttles the Fibre Channel Protocol (FCP) read traffic rate to slow-draining
targets to reduce or eliminate network congestion and alleviate I/O slowdowns to faster targets.
Use the following BCU commands to determine current status and configuration for target rate
limiting settings:
Determining target rate limiting settings through BCU
Use the following BCU commands to determine current status and configuration for target rate
limiting settings:
•
Use the following BCU command to determine target rate limiting speed and enabled status.
ratelim --query <port-id>
where:
