Command Syntax and Usage

hgibp enabledisable

Enables or disables Higig Ingress Back Pressure (IBP) flow control mode. The default value is disabled. If you change the flow-control mode, you must apply and save the changes, then reboot the switch before the change takes effect.

The GbE switch module has two switching chips connected by an internal high-capacity link (Higig). Over subscription of traffic across the Higig link is handled by one of the following flow control modes:

„End-to-End (E2E) Flow Control

„Ingress Back Pressure (IBP) across the Higig link

One of the modes should be enabled, and the other mode disabled. Applications that cannot toler- ate packet loss might require IBP across the Higig link. Higig IPB achieves lossless operation, but it might result in a lower throughput.

bannr <string, maximum 80 characters>

Configures a login banner of up to 80 characters. When a user or administrator logs into the switch, the login banner is displayed. It is also displayed as part of the output from the /info/sys com- mand.

hprompt disableenable

Enables or disables displaying of the host name (system administrator’s name) in the Command Line Interface (CLI).

reminders disableenable

Enables or disables reminder messages in the CLI. The default value is enabled.

cur
