HP StorageWorks Enterprise File Services WAN Accelerator 2.1 Command Line Interface Reference Guide (November 2005)

144 4 - CONFIGURATION-MODE COMMANDS
tacacs-server retransmit
Description Specifies the number of times the client attempts to authenticate with any TACACS+
server. The default value is 1. The range is 0-5. To disable retransmissions set it to 0.
The tacacs-server retransmit command can be overridden in a tacacs-server host
command. The no command option resets the value to the default value.
Syntax tacacs-server retransmit <retries>
Parameters
Example
minna (config) # tacacs-server retransmit 5
minna (config) #
tacacs-server timeout
Description Sets the timeout for retransmitting a request to any TACACS+ server. This command
can be overridden with the tacacs-server host command. The no command option
resets the value to the default value.
Syntax tacacs-server timeout <seconds>
Parameters
Example
minna (config) # tacacs-server timeout 30
minna (config) #
tcp highspeed enable
Enables high-speed Transmission Control Protocol (HSTCP) which provides
acceleration and high throughput for high bandwidth networks where the WAN pipe is
large but latency is high. The no command option disables HSTCP.
HSTCP is activated for all connections that have a Bandwidth-Delay Product (BDP)
larger than 100 packets. If you have a BDP of greater than 512 KB and you are more
interested in filling the WAN pipe than saving bandwidth, you should consider
enabling HSTCP. HSTCP is available only on the HP EFS WAN Accelerator
DL380-
5010.
You need to carefully evaluate whether HSTCP will benefit your network
environment. To enable HSTCP you must disable the Lempel-Ziv (LZ) compression
and Scalable Data Referencing (SDR). With SDR your throughput will bottleneck
between 100 and 150 Mbps, which cancels out the benefit of HSTCP.
<retries> Specifies the number of times the client attempts to authenticate with
any TACACS+ server. The range is 0-5. The default value is 1.
<seconds> Sets the timeout for retransmitting a request to any TACACS+ server.
The range is 1-60. The default value is 3.
