Port Enable and Disable (Port State) 79
Port Enable and
Disable (Port State)
You can enable Ethernet ports (place them online) or disable them (place
them off-line).
Important
Considerations
■
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
■
Because it stops all network traffic through the port, disabling a port
may adversely affect a live network.
■
When a port is enabled, the port transmits packets normally. When a
port is disabled, the port neither sends nor receives packets.
■
The
portState
is
off-line
for disabled ports and
on-line
for enabled
ports that are connected to a network cable.
Port Labels
Port labels serve as useful reference points and as an accurate way for
you to identify ports for management applications.
Labeling Ports
■
Label Ethernet ports so that you can easily identify the devices that are
attached to them (such as LANs, workstations, or servers). For
example, you can assign
engineeringserver
as a label.
■
The new port label appears in system displays the next time that you
display information for that port.
■
Port labels can include up to 32 ASCII characters, including the null
terminator.
