Port Enable and Disable (Port State) 153
Port Enable and
Disable (Port State)
You can
enable
Ethernet ports (place them on-line) or
disable
them
(place them off-line).
Important
Considerations
■
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 frames normally. When a
port is disabled, the port neither sends nor receives frames.
■
The portState is
off-line
for disabled ports and
on-line
for enabled
ports with an active link.
Port Labels
Port labels serve as useful reference points and as an accurate way to
identify ports for management applications.
Implementing
Port Labels
■
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.
■
A 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.
