system prompt after the entire file has been displayed. If you are viewing the Release Notes,
press the
<escape> key to exit the release notes and continue with the installation.
If the file name is incorrect, the following message will be displayed:
Cannot find file "file name"
mc
Displays the Connection Monitor screen. This screen provides information on the remote sites
to which the system is currently connected. The system updates the display as connections are
added or removed.
To display the Connection Monitor screen, Telnet and the terminal emulator must both be set
as the same terminal type. Use the
term set command to do this.
Note: The mc command is also available if you are remotely connected to the CyberSWITCH
by Telnet.
neif
This command will display the system interface table. This table provides information for each
of the system’s physical interfaces, including interface name, interface type, slot and port
number, and the operational status of each interface (up or down). This information can help
to determine system problems by identifying those physical interfaces that are not operating as
expected. Refer to the following example:
The definitions of the interface types and the associated status possibilities are as follows:
Ethernet
Each Ethernet port is considered an Ethernet interface. An Ethernet interface is “up” if the
Ethernet port is capable of forwarding packets to/from the LAN. An Ethernet interface is
“down” if the Ethernet port cannot be used to forward packets to/from the LAN.
Basic Rate (D-Channel)
Each Basic Rate line which contains at least one data link is considered a Basic Rate
(D-Channel) interface. A Basic Rate (D-Channel) interface is “up” if at least one data link
associated with the interface is “up.” A Basic Rate interface is “down” if none of the data
links associated with the interface is “up.”
Basic Rate (Permanent)
Each Basic Rate line which is used by a dedicated access is considered a Basic Rate
(Permanent) interface. A Basic Rate (Permanent) interface is “up” if the serial layer 1 is
“up” for the line. The dedicated access does not have to be “up” for the interface to be
considered “up”. A Basic Rate (Permanent) interface is considered to be down if the serial
layer 1 is “down” for the line.
