SET BPORT_MAU SQUELCH
2-97
SET BPORT_MAU
SQUELCH
Use the SET BPORT_MAU SQUELCH command to establish Squelch Mode as
either normal or low for ports on 10BASE-T SwitchModules. By default, the
squelch level is set to normal to conform to the 10BASE-T standard.
In general, 3Com recommends using normal squelch. Ensure the squelch level at
both ends of the link matches. If you change the squelch level at the
SwitchModule, you must change the squelch setting at the transceiver also.
If your network experiences too many illegally short packets (runts) in low
squelch mode, change the setting back to normal.
Format
Example
The following command sets port 1 in slot 5 to a low squelch level:
CB5000>
set bport_mau 5.1.1 squelch low
Squelch set to LOW.
Related Command
SHOW BPORT_MAU VERBOSE
slot.port.mau Selects a port for squelch mode setting.
slot (1 through 17) is the slot ID and port (1 through 24) is the port
number. Use 1 as the mau variable. For example, to specify port 4 on
the slot with slot ID 6, enter
6.4
slot.
all
Selects a slot for squelch mode setting. For example, to specify all
ports on the slot with slot ID 6, enter
6.all
low
Sets squelch mode to low (sensitive). Ports are able to receive weaker
signals, allowing longer link distances. Increases the achievable link
distance, but with the added risk of losing packets to impulse noise.
normal
Sets squelch mode to normal. Ports receive signals compliant with the
10BASE-T standard.
