ORACLE#

Field descriptions include:

  • Session Director contains the hostname of the cluster OCSBCs that are connected to the SLB.
  • Hdl contains the clustered OCSBC handle, an internal shorthand that identifies a specific cluster member. The show balancer members command provides a handle to hostname mapping.
  • State contains the current OCSBC state. Valid states are:
    • Init — during initial handshaking with the SLB
    • InService — healthy and operating normally
    • Rebalance — during a cluster expansion/contraction operation
    • LostControl — no longer communicating with the SLB
  • Tunnel displays (the number of tunnels in service)/(the number of tunnels configured on the OCSBC).
  • Svcs contains the number of advertised services (protocols) that the OCSBC has negotiated with the SLB.
  • Version contains the software version running on that OCSBC.
  • HW identifies the hardware platform (in this case, VM identifies virtual machines).
  • LastPing is not currently used.

When issued with an optional hostname argument, the show ccd sds command provides a detailed report for the target hostname.

ORACLE#

State

  • State — the current OCSBC state
  • Handle — the OCSBC handle
  • Tunnels — the current number of OCSBC tunnels
  • ServicePorts — the current number of OCSBC service ports
  • HW Type — the hardware platform (in this case, SD3 identifies an Acme Packet 4500 OCSBC)
  • SW Version — the installed software revision level
  • Last Ping — the number of elapsed milliseconds, since a ping/keepalive was received from this OCSBC
  • App Count — the number of applications supported by the OCSBC

Services State

  • Service — the realm advertised by the OCSBC in the Service Port ID
  • App — the supported protocol: SIP
  • SVCPorts — the current number of service ports
  • Tunnels — the current number of tunnels
  • endpoints — the cumulative number of endpoints for this service
  • DropCount — the number of elements to drop when rebalancing this OCSBC

Tunnel State

  • # — the tunnel index (0 or 1)
  • Tunnel — the SLB and OCSBC tunnel IP address
  • App — the supported protocol: SIP
  • Handle — the handle for the tunnel
  • Svcs — the number if service ports supporting the tunnel
  • LastHB — the number of elapsed milliseconds since a heartbeat was received from the remote end of this tunnel

Tunnel Metrics

  • # — the tunnel number (0 or 1)
  • CPU — the current CPU utilization rate
  • Max — the maximum supported CPU utilization rate, if this value is exceeded, the tunnel implements a load limit algorithm
  • CurReg — the current number of registrations supported by the OCSBC
  • RegLimit — the maximum number of registrations supported by the OCSBC
  • CurSess — the current call count reported by the OCSBC
  • MaxSess — the maximum sessions for which the OCSBC is licensed
  • State — whether or not the tunnel is in service
  • Mem% — the current memory utilization
  • Max — the maximum supported memory utilization rate, if this value is exceeded, the tunnel implements a load limit algorithm
  • OverLoad — whether or not the OCSBC is reporting itself overloaded, and therefore out of contention for accepting new traffic

Service Port Data

  • Service Port — the service path (the concatenation of realm, IP address, port number, and IP Level 4 protocol number — 17 for UDP, 6 for TCP)
  • App — the supported protocol: SIP
  • Handle — the handle for the service port
  • TunNdx — the tunnel the service port is registered for
  • Avail — current availability (yes or no) determined by the presence of heartbeats
