Purpose
Command or Action
Specifies the time interval, in seconds, for which the SGSN of the
iWAG waits for before sending an echo request message. The range
interval echo-request request-number
Example:
Router(config-gtp)# interval echo-request
60
Step 6
is from 60 to 65535. The default value is 60. The value of 0 disables
the Echo Request feature.
Configures the transport interface to communicate with the GGSN.
interface local GigabitEthernet slot/subslot/port
Example:
Router(config-gtp)# interface local
GigabitEthernet 0/0/3
Step 7
Configures an ASCII regular expression string to be matched against
the Access Point Name (APN) for GPRS load balancing.
apn apn-name
Example:
Router(config-gtp)# apn example.com
Step 8
Sets the IP address for the GGSN.
ip address ggsn ip-address
Example:
Router(config-gtp-apn)# ip address ggsn
192.170.10.2
Step 9
Specifies the default gateway address of the subscriber.
This is the default gateway address of the IP provided by
the GGSN using GTP, and not the default gateway address
on the physical local interface that the subscriber is
connected to. They can be the same, but we recommend
that they be two different subnets.
Note
default-gw address prefix-len value
Example:
Router(config-gtp-apn)# default-gw
192.171.10.1 prefix-len 16
Step 10
Specifies the Domain Name System (DNS) IP servers that are
available for a DHCP client.
dns-server ip-address
Example:
Router(config-gtp-apn)# dns-server
192.165.1.1
Step 11
Specifies the primary and backup DHCP servers that are used to
allocate IP addresses to mobile station users entering a particular
public data network (PDN) access point.
dhcp-server ip-address
Example:
Router(config-gtp-apn)# dhcp-server
192.168.10.1
Step 12
Configures the duration (in seconds) of the lease for an IP address
that is assigned from a Cisco IOS DHCP Server to a DHCP client.
dhcp-lease seconds
Example:
Router(config-gtp-apn)# dhcp-lease 3000
