SET SWITCH PORT

Syntax SET SWITCH PORT={port-list|ALL} [POLARITY={MDI|MDIX}]

[BCLIMIT={NONE|limit}] [DESCRIPTION=description]

[DLFLIMIT={NONE|limit}] [INFILTERING=OFF|ON]

[MCLIMIT={NONE|limit}] [SPEED={AUTONEGOTIATE|10MHALF|

100MFAUTO}]

where:

■ port-list is a port number, a range of port numbers (specified as n-m), or a

comma separated list of port numbers and/or ranges. Port numbers start

at 1 and end at m, where m is the highest numbered switch port.

■ limit is a decimal number, from 0 to the maximum value of the limit

variable based on the particular switch hardware.

■ description is a string 1 to 47 characters long. Valid characters are any

printable characters.

Description This command modifies the value of parameters for switch ports.

The PORT parameter specifies the ports for which parameters are modified. If

the command would succeed on a subset of the ports specified, but cause an

error on the others, then the command as a whole fails and has no effect.

While the user may specify SET SWITCH PORT commands using groups of ports, the

create config command on page 1-69 of Chapter 1, Operation generates a separate SET

SWITCH PORT command for each port.

The POLARITY parameter specifies MDI mode (the transmit and receive pairs

are not crossed), or MDI-X mode (the transmit and receive pairs are crossed)

for the port. For the POLARITY parameter to take effect, auto MDI/MDI-X

mode must be disabled using the DISABLE SWITCH PORT command on

page 3-26. If auto MDI/MDI-X mode has not been disabled, the port remains in

1 2 ... 26 27 28 29 30 31 32 33 34 35 36 ... 47 48
