options, see Port Configuration, page 2-30 ; port display forms are described
below.
Interface Port Display Forms
You can display the following information for each available interface:
Oper Status
An interface’s Operational Status is its actual state; note that this may not always
be the same as the requested, or administrative state:
• ON — the port is administratively enabled, a link is present, and the port is
functioning normally.
• NLK (no link) — the port is administratively enabled, but no link is present.
This typically indicates that no cable is currently connected to the interface.
• OFF — the port is not operational; this may be because it has been
administratively disabled, it has malfunctioned in some way, or it is
attempting to move into a testing state. Note that the color code (described in
the following section,
page 2-20 ) that accompanies this display will indicate
which of these three conditions has caused the OFF state.
• TEST — the port is being tested.
Link Status
A port’s Link Status tells you whether or not the port has a valid connection to the
node at the other end of the cable segment. Note that this status does not provide
any indication of administrative (ON or OFF) or operational status.
• NLK (no link) — no link is present.
• LNK — a link is present.
Duplex Mode
The Duplex Mode status indicates which interfaces have been configured to
operate in Full Duplex mode, and which are operating in standard mode.
Interfaces which are operating in full duplex mode can both transmit and receive
packets at the same time, effectively doubling the wire speed; interfaces in
standard mode must finish transmitting before they can receive, and vice versa.
• Stand — the interface is operating in standard mode.
• Full — the interface is operating in full duplex mode.
