ID Description Found In Fixed In
29937232

GW unreachable and NetBufCtrl MBUFF errors - This can result in system instability including crash, gw-unreachable and redundancy issues. System will switchover if in HA. Show Buffers output will normally show an increase of errors reported in the NetBufCtrl field due to mbuf’s not being freed.

S-Cz8.1.0 S-Cz8.1.0m1p18
None

This version's enhancement to SMP-Aware Task Load Limiting, which adds a second parameter to the sip-config load-limit option, is currently not supported.

SCZ740 TBD

24574252

The show interfaces brief command incorrectly shows pri-util-addr information in its output. SCZ740 TBD

26790731

Running commands with very long output, such as the "show support-info" command, over an OVM virtual console might cause the system to reboot.

Workaround: You must run the "show support-info" command only over SSH.

SCZ800 TBD
26338219 The packet-trace remote command does not work with IPv6. SCZ740 TBD

26497348

When operating in HA mode, the OCSBC may display extraneous "Contact ID" output from the show sipd endpoint-ip command. You can safely ignore this output. SCZ800 TBD

26258705

The show sipd srvcc command does not display the correct number of unsuccessful aSRVCC calls. SCZ800 TBD

26598075

When running on the Acme Packet 4600, the OCSBC sends a 200OK with IPv4 media address for call flows with offerless INVITES and the OCSBC configured with add-sdp-invite=invite and ALTC configured for IPv6 on the egress. SCZ800 TBD

26559988

In call flows that include dual ALTC INVITEs from the callee, and subsequent Re-INVITEs that offer and ALTC with IPv6 video, the OCSBC may not include the m lines in the SDP presented to the end stations during the Re-INVITE sequence. This results in the call continuing to support audio, but the video failing. SCZ800 TBD

26313330

In some early media call flows, the OCSBC may not present the correct address for RTP causing the call to fail. SCZ800 SCZ800p2, SCZ740m1p6

26281599

The system feature provided by the phy-interfaces overload-protection parameter and overload-alarm-threshold sub-element is not functional. Specifically, enabling the protection and setting the thresholds does not result in trap and trap-clear events based on the interface's traffic load.

The applicable ap-smgmt.mib SNMP objects include:

  • apSysMgmtPhyUtilThresholdTrap
  • apSysMgmtPhyUtilThresholdClearTrap
SCZ720 SCZ8.2.0

25144010

When an OCSBC operating on an Acme Packet 6300 fails over, the secondary can successfully add new ACL entries, but it also retains old ACL entries that it should have deleted. SCZ740p1

SCZ810 SCZ740M1

Re-balancing is unavailable on the OCSLB when running an Acme Packet 6300 as a cluster member. Set the SLB cluster-config, auto-rebalance parameter to disabled to use an Acme Packet 6300 as a cluster member from that SLB. SCZ730 TBD

21805139

RADIUS stop records for IWF calls may display inaccurate values. SCZ730b6 TBD

24809688

Media interfaces configured for IPv6 do not support multiple VLANs. SCZ730 TBD
SIP-H323 hairpin calls with DTMF tone indication interworking is not supported. S-CZ720 TBD
The OCSBC stops responding when you configure an H323 stack supporting SIP-H323-SIP calls with the max-calls parameter set to a value that is less than the q931-max-calls parameter.

Workaround: For applicable environments, configure the H323 stack max-calls parameter to a value that is greater than its q931-max-calls parameter.

S-CZ740 TBD
HA Redundancy is not supported for H.323 calls. TBD

21341383

If after upgrading to a S-CZ7.4.0 OCSR software image and its corresponding 7.3 stage3 boot loader, you decide to downgrade to a pre- S-CZ7.3.0 product release, you must install the corresponding 7.2 stage3 boot loader before rebooting with the older image.

TBD

23756306

When the session-router is configured with a operation-mode of session, it does not correctly clear sessions.

S-Cz7.2.0 TBD

23253731

After an HA switchover, the new standby OCSBC retains some IMS-AKA subscriber TCP sockets. You can clear these sockets by rebooting the OCSBC. SCZ730M2 TBD

26183767

When operating in HA mode and handling large traffic loads, the active OCSBC stops responding when you restore large configurations that are different from the configuration the active is currently running. The systems subsequently goes out of service. SCZ800

SCZ740m1p1, SCZ800p1

21975038 MSRP File Transfer is not supported on the Acme Packet 4600, 6100, 6300, and 6350. SCZ810 SCZ810p1
27579686 TSM is not supported in this release. SCZ810 SCZ810p1

27699451

Oracle has qualified the QSFP interface for the OCSR operating over the Oracle X7-2 platform for a single QSFP port operating in 4-port mode. Specifically, 4 media interfaces successfully map to the second port of the QSFP interface using a Hydra cable as physical connections to 10G switch ports. SCZ810 TBD

27811129

When upgrading an OCSBC from a version that uses License Keys to enable CODECs, you must reboot the system after setting any CODEC entitlements to override the License Keys. SCZ810 TBD

27539750

When trying to establish a connection between the SBC and your network, while using TLS version 1.2, the SBC may reject the connection.

Workaround: You may need to adjust your cipher list.

SCZ810 TBD

27911939

When running the OCSBC over the KVM hypervisor and using SR-IOV interface mode, the system fails over when all of following conditions are in effect:

  • 4 forwarding cores
  • 8 signaling cores
  • IMS-AKA in use
  • High call traffic load
SCZ810 TBD
28062411 Calls that require SIP/PRACK interworking as invoked by the 100rel-interworking option on a SIP interface do not work in pooled transcoding architectures. SCZ740 SCZ810m1
28071326 Calls that require LMSD interworking as invoked by the lmsd-interworking option on a SIP interface do not work in pooled transcoding architectures. During call establishment, when sending the 200 OK back to the original caller, the cached SDP is not included. SCZ740 SCZ810m1
None IPSec is not supported on the Acme Packet 3900 and VNF in the CZ8.1.0 release. You must upgrade to CZ8.1.0p1 to get this support. After you upgrade to CZ8.1.0p1, do the following:
  1. Run setup entitlements, again.
  2. Select advanced to enable advanced entitlements, which then provides support for IPSEC on Acme Packet 3900 and VNF systems.
CZ810 CZ810p1
28305575 On VNFs, the system erroneously displays the IPSEC entitlement under "Keyed (Licensed) Entitlements." The error does not affect any functionality and you do not need to do anything. CZ810 CZ820

28367500

When operating the OCSBC on the Acme Packet 6300, the traceroute command does not show hops for an IPv6 traceroute that does not reach the target address. The system successfully displays hops when the traceroute reaches the target and for IPv4 traceroutes. CZ810 TBD

28617938

The anonymize-invite option for CommMonitor is not RTC. To see a change, you must either reboot or toggle the admin state. The following is a general admin state toggle procedure:
  1. Set admin state to disabled.
  2. Save and activate.
  3. Set admin state to enabled.
  4. Save and activate.
CZ810m1 TBD

28618563

The system is not populating the Username AVP in Accounting Requests (ACRs) correctly. When triggered by an INVITE, these AVPs contain only the "@" sign. They do not include the username and domain name portion of the URL. CZ810m1 TBD

28659469

When booting CZ8.1.0M1 on any virtual platform, not all system processes start. This known issue only occurs on initial boot, and not in an upgrade scenario.

Workaround: Reboot the OCSBC a second time, after it initially starts.

CZ810m1 TBD

29931732

The embedded communications monitor probe does not send IPv6 traffic to the Oracle Communications Operations Monitor's mediation engine. SCZ800 TBD
28820258

When running TLS Chat on VMware-PV 4core (SSFD) + 16GB, TLS Chat sessions are gradually decreasing. When looking in Wireshark at EXFO, EXFO forwards a wrong TLS MSRP Chat payload to EXFO UAS.

TCP Chat doesn't have this error.

SCZ800 TBC
