The page includes the following fields:
Object Description
• Trunk Indicates if a port is a member of a trunk. To create trunks and select port
members, see “ Creating Trunk Groups ”
• Name Allows you to label an interface.
(Range: 1-64 characters)
• Admin Allows you to manually disable an interface. You can disable an interface due to
abnormal behavior (e.g., excessive collisions), and then re-enable it after the
problem has been resolved. You may also disable an interface for security
reasons.
• Speed/Duplex Allows you to manually set the port speed and duplex mode. (i.e., with
auto-negotiation disabled)
• Flow Control Allows automatic or manual selection of flow control (that is, with
auto-negotiation disabled). Flow control can eliminate frame loss by “blocking”
traffic from end stations or segments connected directly to the switch when its
buffers fill. When enabled, backpressure is used for half-duplex operation and
IEEE 802.3-2005 (formally EEE 802.3x) for full-duplex operation.
Avoid using flow control on a port connected to a hub unless it is actually required
o solve a problem. Otherwise back pressure jamming signals may degrade
overall performance for the segment attached to the hub.
• Autonegotiation Allows auto-negotiation to be enabled/ disabled. When auto-negotiation is
enabled, you need to specify the capabilities to be advertised. When
auto-negotiation is disabled, you can force the settings for speed, mode, and flow
control. The following capabilities are supported.
-10half -Supports 10 Mbps half-duplex operation
-10full -Supports 10 Mbps full-duplex operation
-100half - Supports 100 Mbps half-duplex operation
-100full - Supports 100 Mbps full-duplex operation
-1000full (Combo ports only) -Supports 1000 Mbps full-duplex operation
(Default: Autonegotiation enabled; Advertised capabilities for 100BASE-TX –
10half, 10full, 100half, 100full; 1000BASE-T – 10half, 10full, 100half, 100full,
1000full; 1000BASE-SX/LX/LH – 1000full)
