prefer { fallback-for-dns | local }
Indicates whether to use a DNS query to obtain the address or to use a locally configured peer MME address:
fallback-for-dns
- Instructs the SGSN to perform a DNS query to get the IP address of the peer
MME. If the DNS query fails, then the IP address configured with this command is used.
local
- Use the locally configured address for the MME address.
Important:
If the
prefer
command is used to change an existing peer-mme configuration (with the same LAC
and RAC) from
fallback-for-dns
to
local
or from
local
to
fallback-for-dns
, the new setting overwrites the
previously configured setting for all interfaces.
address { ipv4_address | ipv6_address }
Specifies the IP address of the peer MME. Currently, the IPv6 address option is not supported on the S4-
SGSN.
SGSN.
ipv4
must be in standard dotted-decimal notation.
interface { gn [ s3 ] | s3 [ gn ] }
Specifies the interface to use for communication between the SGSN and the peer MME:
gn
: Use the Gn interface between the S4-SGSN and the MME in the LTE network.
s3
: Use the S3 interface between the S4-SGSN and the MME in the LTE network. This is the default
setting.
Usage
Use this command to instruct the S4-SGSN how to determine a peer MME address, via DNS or local
configuration. For a local address, use this command to configure the peer MME address.
This command also sets the interface type to be used between the peer MME and the SGSN.
configuration. For a local address, use this command to configure the peer MME address.
This command also sets the interface type to be used between the peer MME and the SGSN.
Example
The following command configures LAC/RAC
111/22
for the peer MME and instructs the SGSN to use the
MME’s locally configured IPv4 address of
1.1.1.1
and an S3 interface between the MME and the SGSN.
