Configuring Gigabit Ethernet Ports

Configuring Gigabit Ethernet Port Priority Levels

You can configure the priority level for each port. When two ports simultaneously request access to the
switching bus, the switch uses the priority level to determine the order in which the ports get access.
To configure the port priority level, perform this task in privileged mode:
Task
Step 1 Configure the priority level for a port.
Step 2
Verify that the port priority level is configured correctly. show port [mod_num[/port_num]]
This example shows how to configure the port priority level to high for port 2/1 and verify that the port
priority is configured correctly:
Console> (enable) set port level 2/1 high
Port 2/1 level set to high.
Console> (enable) show port 2/1

Configuring Flow Control on Gigabit Ethernet Ports

To configure flow control on a Gigabit Ethernet port, perform this task in privileged mode:
Task
Step 1
Configure the flow-control parameters on a Gigabit Ethernet
port.
Step 2 Verify the flow-control configuration.
This example shows how to configure transmit and receive flow control and how to verify the
flow-control configuration:
Console> (enable) set port flowcontrol send 2/1 on
Port 2/1 flow control send administration status set to on
(port will send flowcontrol to far end)
Console> (enable) set port flowcontrol receive 2/1 on
Port 2/1 flow control receive administration status set to on
(port will require far end to send flowcontrol)
Console> (enable) show port flowcontrol 2/1
