show ccd sds

The show ccd sds command displays a table containing an overview of all of the data gleaned from the CCP from each OCSBC. The syntax for this command extends to allow individual SBC IDs or the all and size arguments. The size argument is explained in the Display Behavior for Show Commands with the Size Argument topic.

The full syntax of the command includes:

An example of the basic command, show ccd sds, is shown immediately below.

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 <id> 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

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

When issued with an optional hostname argument and the optional tunnel metrics argument, the show ccd sds <id> <tunnel metrics> command provides a detailed report on specific system capacities, as reported by the target hostname via CCP.

Tunnel Metrics Data

  • # — 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
