• If you logged into the CI menus with read-write access, you enter the CLI in
privExec mode and use the commands to move to the other command modes.
Port numbering
The BPS 2000 operates either in standalone mode or in stack mode. The BPS
2000 has 24 10/100 Mb/s ports on the front, as well as an uplink slot that allows
you to attach a media dependent adapter (MDA). The MDAs available for the
BPS 2000 can have up to 4 ports. Thus, you have a maximum of 28 ports on one
BPS 2000.
In stack mode, the BPS 2000 operates either in pure BPS 2000 stack mode or in
hybrid stack mode. The hybrid stack mode is a combination of the BayStack
450or 410 switches and BPS 2000 switches in one stack.
The port numbering scheme for the CLI is that if the BPS 2000 is in standalone
mode, enter just the port number (possible range, depending on MDA, is 1 to 28).
The port numbering scheme when you are operating in either pure BPS 2000 stack
mode or in the hybrid stack mode is to enter a number for the positions of the
switch within the stack (possible range 1 to 8), a slash (/), and the number of the
port on the BPS 2000 (possible range 1 to 28, depending on the MDA). For
example, if you are configuring unit
# 4 in the stack and the 16th port on that unit, enter 4/16. (Some commands allow
you to enter
all, which affects all ports in the system, or none, which affects
none of the ports in the system.)
When you are operating in standalone mode, enter just the port number; do not
enter an integer for unit or a slash.
The CLI uses the variable portnum (or port-num) in some commands; you should
enter the port number according to the guidelines in the above paragraphs for the
variable portnum.
To view the unit numbers in the stack, issue the
show stack-info command
(“show stack-info command” on page 45). You must be in the Privileged EXEC
(privExec) mode to issue this command.
