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

Setting the Port Speed
You can configure the port speed on 10/100-Mbps Fast Ethernet modules. Use the auto keyword to have
the port autonegotiate speed and duplex mode with the neighboring port.
Make sure the device on the other end of the link is also configured for autonegotiation or a port speed

or duplex mismatch will result.
