Creating Availability Profiles for Servers

To create an availability profile for servers:

1. Access the availability check option under SIP routing destinations and assign a profile name.
   edit services border-signaling-gateway gateway bsg-1 sip availability-check-profiles avail-profile-1
2. Assign one of the following keepalive strategies:

   • Check all servers, whether they are currently up or down.

     [edit services border-signaling-gateway gateway bsg-1 sip routing-destinations availability-check-profiles avail-profile-1]user@host# set keepalive-strategy send-always failures-before-unavailable 2 successes-before-available 2

   • Check only servers that are unavailable.

     [edit services border-signaling-gateway gateway bsg-1 sip routing-destinations availability-check-profiles avail-profile-1]user@host# set keepalive-strategy send-when-unavailable successes-before-available 2

   • Do not check servers. Establish a blackout period after which a server that is down is removed from the blacklist.

     [edit services border-signaling-gateway gateway bsg-1 sip routing-destinations availability-check-profiles avail-profile-1]user@host# set keepalive-strategy do-not-send blackout-period 15
3. Set a time interval for sending ping messages to check server availability.

   • To assign a time interval for sending messages to servers that are up:

     user@host# set keepalive-interval available-server 5

   • To assign a time interval for sending messages to servers that are down:

     user@host# set keepalive-interval unavailable-server 5
4. Set the number of seconds with no response following a ping, after which the ping is considered to have failed.
   user@host# set transaction-timeout 5
