Configuring HSS Groups

To configure HSS groups:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the system-level configuration elements.
```
ORACLE(configure)# session-router
```
Type hss-group and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# hss-group
ORACLE(hss-group)#
```
name—Enter a unique name for the HSS group in Name format.
state—Enable or disable the HSS group on the Oracle Communications Unified Session Manager. The default value is enabled. Valid values are:
- enabled | disabled
origin-host-identifier— Set this to a string for use in constructing a unique Origin Host AVP. This setting always takes precedence over the origin-host-identifier configured for the home-subscriber-server. This setting is required.
strategy—Indicate the HSS server allocation strategy you want to use. The strategy you chose selects the HSS servers that will be made available by this hss-group. The default value is hunt. The valid values are:
- hunt—Selects HSS servers in the order in which they are listed. For example, if the first server is online, all traffic is sent to the first server. If the first server is offline, the second server is selected. If the first and second servers are offline, the third server is selected. When the Oracle Communications Unified Session Manager detects that a higher priority HSS is back in service, it routes all subsequent traffic to that HSS.
- roundrobin—Selects each HSS server in the order in which they are listed in the destination list, selecting each server in turn, one per session.
- failover — Selects the first server in the list until failure is detected. Subsequent signaling goes to the next server in the list.

hss-configs—Identify the HSS servers available for use by this hss-group. This list can contain as many HSS servers as is necessary. An hss-config list value must correspond to a valid hss-config.

Display syntax for the hss-configs parameter by typing the question mark character after the parameter name on the ACLI.

ORACLE(hss-group)# hss-configs ?
<string> list of home-subscriber-server configs for this group
         for single-entry: hss1
         for multi-entry: (hss1 hss2)
         for adding an entry to an existing list: +hss3
         for deleting an entry from an existing list: -hss3
         for multiple entries add/remove from a list: +/-(hss1 hss2)

The following example shows an HSS group using the hunt allocation strategy applied.

hss-group
        name                           group-test1
        state                          enabled
        origin-host-identifier
        strategy                       hunt
        hss-configs                    hss1, hss2
