Configuring the System Mode
The Cisco SCE 8000 devices operates in one the following system modes:
•
IPv4 only system mode—All traffic processors handle only IPv4 traffic.
•
IPv6 only system mode—All traffic processors handle only IPv6 traffic.
•
Dual stack system mode—Default system mode. All traffic processors handle both IPv4 and IPv6
traffic. Dual static subscribers can either be configured statically on the device or they can be
configured through Gx. The number of subscriber mappings in the device is divided between IPv4
and IPv6 based on the const -db value.
The system mode is configured by modifying the value of the
seCommonConstDb.box.ipv6MappingsPercentage
const -db.
The default value of the
seCommonConstDb.box.ipv6MappingsPercentage
const-db is 20. Dual stack
mode is active if the value is between 1 and 99. IPv4 mode is active when the value is 0 and IPv6 mode
when the value is 100.
To configure the IPv4 only mode, follow these steps:
Step 1
Enter the Global Configuration mode:
SCE8000#
configure
Step 2
Configure the IPv4 only mode:
From the Global Configuration prompt, enter
debug const-db name
seCommonConstDb.box.ipv6MappingsPercentage value 0
and press
Enter
.
Step 3
Copy the running configuration to the startup configuration:
SCE8000#>
copy running-config startup-config
Step 4
Reboot the Cisco SCE 8000 device.
To configure the IPv6 only mode, follow these steps:
