Chapter 4 Configuring Ethernet and Fast Ethernet Switching
Configuring Ethernet and Fast Ethernet Ports
This example shows how to set the name for ports 1/1 and 1/2 and how to verify that the port names are
configured correctly:
Console> (enable) set port name 1/1 Router Connection
Port 1/1 name set.
Console> (enable) set port name 1/2 Server Link
Port 1/2 name set.
Console> (enable) show port 1
Port Name Status Vlan Level Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
1/1 Router Connection connected trunk normal half 100 100BaseTX
1/2 Server Link connected trunk normal half 100 100BaseTX
<...output truncated...>

Setting Ethernet and Fast Ethernet Port Priority Levels
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:
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.
Console> (enable) show port 1
Port Name Status Vlan Level Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
1/1 Router Connection connected trunk high half 100 100BaseTX
1/2 Server Link connected trunk normal half 100 100BaseTX

Setting Ethernet and Fast Ethernet Port Speeds
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.
Task
Command
Step 1
Configure the priority level for a port.
set port level mod_num/port_num
{normal | high}
Step 2
Verify that the port priority level is configured
correctly.
show port [mod_num [/port_num]]
