Expert Settings (Option 5)

Note: You can change these settings using telnet or serial connections only, not on the Web Manager.

Caution: Changing the expert settings can drastically affect the performance and access to the product. These settings should only be changed by an experienced network administrator.

Select 5 to configure expert settings.

Figure 9-1 Expert Settings

TCP Keepalive time in s (1s - 65s; 0s=disable): (45) ?

ARP Cache timeout in s (1s - 600s) : (600) ?

CPU performance (0=Regular, 1=Low, 2=High): (0) ?

Disable Monitor Mode @ bootup (N) ?

HTTP Port Number : (80) ?

MTU Size (512 - 1400): (1400) ?

TCP Re-transmission Timeout (500 - 4000) (ms): (500) ?

Enable alternate MAC (N) ?

Ethernet connection type: (0) ?

TCP Keepalive Time In Seconds

This option allows you to change how many seconds the unit waits during a silent connection before attempting to see if the currently connected network device is still on the network. If the unit gets no response, it drops that connection. The default setting is 45.

TCP Keepalive time in s (1s - 65s; 0s=disable): (45) ?

ARP Cache Timeout In Seconds

Whenever the unit communicates with another device on the network, it adds an entry into its ARP table. The ARP Cache timeout option allows you to define how many seconds (1-600) the unit will wait before timing out this table. The default setting is 600.

ARP cache timeout in s (1s - 600s) : (600) ?

CPU Performance

This option allows you to increase the CPU performance required to use the higher baud rates on the serial interface (460800 bps and 921600 bps). The default CPU performance mode supports up to 230400 bps.

CPU performance (0=Regular, 1=Low, 2=High): (0) ?

If a baud rate of 460 Kbps or 920 Kbps is set and the high performance mode is disabled, the operation of the serial channel would be out of the specified error tolerance, thereby leading to inconsistent speed settings on the two ends of the serial channel.
