Port Configuration
Use the Port Configuration menus to configure any port on the switch.
Figure 3-36. Port Configuration
Parameter | Default | Description |
Flow Control Mode | Enabled | Allows you to enable or disable flow control for all |
|
| ports on the switch. |
Admin Status | Enable | Allows you to disable a port due to abnormal |
|
| behavior (e.g., excessive collisions), and then re- |
|
| enable it after the problem has been resolved. |
|
| You may also disable a port for security reasons. |
Duplex Status | Auto- | Used to set the current port duplex mode or auto- |
| Negotiation | negotiation. The default is |
Flow Control status | Enabled | Used to enable or disable flow control. Flow |
|
| control can eliminate frame loss by “blocking” |
|
| traffic from end stations or segments connected |
|
| directly to the switch when its buffers fill. Back |
|
| pressure is used for half duplex and IEEE 802.3x |
|
| for full duplex. Note that flow control should not be |
|
| used if a port is connected to a hub. |
802.1Q Trunk Status | Disabled | Used to enable/disable the VLAN trunk status for |
|
| the port. A VLAN Trunk link between two VLAN- |
|
| aware switches will carry traffic from all VLANs, |
|
| allowing VLAN tagged frames to maintain their |
|
| VLAN ID across multiple switches. When |
|
| enabled, a port joins all configured VLANs and the |
|
| untagged port VLAN ID (PVID) is set to 4000, a |
|
| reserved VLAN ID for trunk ports. |
