set gprs idle <value>
The
idle
parameter defines an idle time interval for the GPRS session: if no packet is transmitted or
received during this interval, the GPRS session is terminated. If the on-demand mode is not set, the
session is automatically re-established.
It is possible to calculate inactivity time only for received data and not considering transmitted data,
by using the commands:
set gprs idle 0
set gprs rx-idle <value>
In order to set the max bandwidth speed, the
CLI
command is (N is in Kbit/sec):
set gprs bandwidth-max N
The command:
set gprs mtu 1500
sets the Max Transfer Unit (MTU) of the GPRS interface. In some APN configurations the size of
transmitted packets is restricted to 1476. In these cases the following command is necessary:
set gprs mtu 1476
The following commands:
set gprs lcp-echo-interval
set gprs lcp-echo-failure
set the frequency of transmission of lcp echo request packets and the number of attempts before
ending the GPRS interface. It will be automatically re-established.
It is also possible to negotiate DNS parameters directly from the peer by using the command:
set gprs usepeerdns
In order
to set the authentication mode on GPRS connections (the default is CHAP authentication),
the following command is used:
set gprs sgauth <auth_type_code>
Different authentication modes can be specified by using the following values:
0
: no authentication
1
: PAP authentication
2
: CHAP authentication
3
: PAP and CHAP authentication
In UMTS/HSDPA/HSUPA connection the following command should be used in order to set PAP
authentication:
set gprs directive refuse-chap
The Mobile Network (3G or 2G) can be selected using appropriate commands:
set gprs auto-network
The Mobile Network choice is made by the radio module which automatically selects the best
network at that moment. According to the radio signal, the radio module will automatically pass
from a network to another using a roaming procedure.
