Table 3-3Telnet Commands and Parameters (continued)

passwd

Password that allows administrators to control changes of HP Jetdirect print server

 

configuration parameters using Telnet, the HP Embedded Web Server, or HP Web

 

Jetadmin. For example, passwd jd1234 jd1234 sets the password to jd1234. (You

 

must enter the password jd1234 twice for confirmation.)

 

Enter up to 16 alphanumeric characters. Clear the password using a cold reset or enter

 

the command without a password and confirmation entry.

 

 

sys-location

Physical location of the device. Enter up to 255 alphanumeric characters.

 

 

sys-contact

Name of the network or device administrator. Enter up to 255 alphanumeric characters.

 

 

ssl-state

Print server's security level for Web communications, using the following values:

 

1: Enable forced redirection to the HTTPS port. Use only HTTPS (secure HTTP)

 

communications.

 

2: Disable forced redirection to HTTPS. Use both HTTP and HTTPS communications.

 

 

security-reset

Reset security settings on the print server to factory default values.

 

0 (default): Do not reset.

 

1: Reset.

 

 

Wireless 802.11 Main

 

 

 

Wireless Mode

802.11 wireless mode.

 

B/G_MODE: Use 802.11b or g.

 

B/G/N_MODE (default): Use 802.11b, g, or n.

 

 

Guard Interval

The space between transmitted symbols (characters). Can eliminate inter-symbol

 

interference (ISI), which occurs when echoes or reflections from one symbol interfere

 

with another. A long interval can reduce echoes, but decrease the data rate. A short

 

interval can increase the data rate by approximately 10 percent.

 

AUTO (default): Automatically set the guard interval based on the wireless mode.

 

SHORT: Set to short interval (400 ns).

 

LONG: Set to a long interval (800 ns).

 

 

AMSDU Aggregation

Aggregating 802.11n MAC service data units packs them into frames to reduce

 

overhead and increase the data rate. Enabling aggregation allows a maximum frame

 

size of 7935 bytes.

 

ENABLE (default): Enable aggregation.

 

DISABLE: Disable aggregation.

 

 

Block ACKs

Use block acknowledgement of AMPDUs.

 

This mechanism allows each of the aggregated data frames to be individually

 

acknowledged or retransmitted if affected by an error. (Automatically enabled when

 

AMPDU Aggregation is enabled.)

 

ENABLE (default): Enable AMPDU block acknowledgements.

 

DISABLE: Disable AMPDU block acknowledgements.
