Table 3.4 Telnet Commands and Parameters (12 of 18) tcp-mss Specifies the maximum segment size (MSS) that the HP Jetdirect print server will advertise for use when communicating with local subnets (Ethernet MSS=1460 bytes or more) or remote subnets (MSS=536 bytes): 0: (default) All networks are assumed to be local (Ethernet MSS=1460 bytes or more). 1: Use MSS=1460 bytes (or more) for subnets, and MSS=536 bytes for remote networks. 2: All networks are assumed to be remote (MSS=536 bytes), except the local subnet. MSS affects performance by helping to prevent IP Fragmentation that may result in data retransmission. tcp-msl Specifies the maximum segment life (MSL) in seconds. The range is 5 - 120 seconds. The default is 15 seconds. default-ip Specifies the IP address to use when the print server is unable to obtain an IP address from the network during a forced TCP/IP reconfiguration (for example, when powered off/on or manually configured to use BOOTP/DHCP). DEFAULT_IP: sets the legacy default IP address 192.0.0.192. AUTO_IP: sets a link-local IP address 169.254.x.x. The initial setting is determined by the IP address obtained when first powered on. default-ip-dhcp Specifies whether DHCP requests will be periodically transmitted when a legacy default IP address 192.0.0.192 or link-local IP address 169.254.x.x has been automatically assigned. 0: Disables DHCP requests. 1 (default): Enables DHCP requests. TCP/IP Diagnostics Command Description Last Config IP (Read-only parameter) The IP address of the system from which the HP Jetdirect print server's IP address was configured. TCP Conns Refused (Read-only parameter) The number of client TCP connections that are refused by the print server. TCP Access Denied (Read-only parameter) The number of times that client systems were denied access to the print server because there was no allowable entry in the print server's host access list. DHCP Lease Time (Read-only parameter) DHCP IP address lease duration time (seconds). DHCP Renew Time (Read-only parameter) DHCP T1 timeout, specifying the DHCP lease renewal time (seconds).

TCP/IP Configuration 92

tcp-mss

Specifies the maximum segment size (MSS) that the

HP Jetdirect print server will advertise for use when

communicating with local subnets (Ethernet MSS=1460

bytes or more) or remote subnets (MSS=536 bytes):

: (default) All networks are assumed to be local (Ethernet

MSS=1460 bytes or more).

: Use MSS=1460 bytes (or more) for subnets, and

MSS=536 bytes for remote networks.

: All networks are assumed to be remote (MSS=536 bytes),

except the local subnet.

MSS affects performance by helping to prevent IP

Fragmentation that may result in data retransmission.

tcp-msl

Specifies the maximum segment life (MSL) in seconds. The

range is 5 - 120 seconds. The default is 15 seconds.

default-ip

Specifies the IP address to use when the print server is

unable to obtain an IP address from the network during a

forced TCP/IP reconfiguration (for example, when powered

off/on or manually configured to use BOOTP/DHCP).

DEFAULT_IP: sets the legacy default IP address

192.0.0.192.

AUTO_IP: sets a link-local IP address 169.254.x.x.

The initial setting is determined by the IP address obtained

when first powered on.

default-ip-dhcp

Specifies whether DHCP requests will be periodically

transmitted when a legacy default IP address 192.0.0.192

or link-local IP address 169.254.x.x has been automatically

assigned.

0: Disables DHCP requests.

1 (default): Enables DHCP requests.

connections that are refused by the print server.

TCP Access Denied

(Read-only parameter) The number of times that client

systems were denied access to the print server because

there was no allowable entry in the print server

’

s host access

list.

DHCP Lease Time

(Read-only parameter) DHCP IP address lease duration

time (seconds).

DHCP Renew Time

(Read-only parameter) DHCP T1 timeout, specifying the
