Hashing Algorithm Configuration - Cisco ASR 5000 Series 3G Home NodeB Administration Manual

HNB-GW Service Configuration Procedures
Step 13 Configure GTP-U service parameters by applying the example configuration in the GTP-U Service Configuration
section.
Step 14
Configure RTP pool parameters by applying the example configuration in the RTP Pool Configuration section.
Step 15
Create and configure the HNB-GW service and associate related parameters with HNB-GW by applying the example
configuration in the HNB-GW Service Configuration section.
Step 16 Optional. Configure Security Gateway parameters with Crypto-template and enable SeGW by associating it with HNB-
GW to enabling SeGW by applying the example configuration in the Security Gateway and Crypto Template
Configuration section.
Step 17
Optional. Configure x.509 security certificate for FAP with Crypto-template by applying the example configuration in
the x.509 Certificate Configuration section.
Step 18 Optional. Modify the HNB-CS Network configuration to support multiple MSC selection without Iu-Flex by applying
the example configuration in the Multiple MSC Selection without Iu-Flex Configuration section.
Step 19
Optional. Modify the HNB-GW service configuration to support the Open Access mode support for open HNBs and
paging parameters by applying the example configuration in the Open Access Mode Configuration section.
Step 20
Verify your HNB-GW configuration by following the steps in the HNB-GW Service Configuration Verification section.
Step 21
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode
command

Hashing Algorithm Configuration

Use the following example to configure the system to use SBIA for hashing algorithm in ECMP-LAG for even
distribution of RTP packets over IuCS interface:
recommended in other deployment scenarios where HNB-GW is used in combination with other services.
configure
ecmp-lag hash use-sbia-only
end
Notes:
 This is a global configuration level command and will apply to all services configured on chassis.
 This configuration provides the even distribution of RTP traffic seen over IuCS interface.
 If this option is not chosen, system uses IP Source Address, IP Destination Address, IP Protocol and Source
Boxer Internal Address as inputs to the hashing algorithm for ECMP-LAG distribution.
