This section describes the resolved caveats pertaining to the Cisco SCE 8000 platform for Cisco SCOS Release 4.2.0:
P2P graph shows spike beyond configured PIR during peak hours.
SCOS Diameter Gy crashes on Cisco SCE, if CCA-I does not have Result-Code AVP at command level.
In SCE2000 running SCOS 3.8.5, the standby Cisco SCE in cascade mode does not remove anonymous subscribers.
If you configure the access list in Cisco SCE 8000, the Telnet process crashes with the attack-filter query dual-sided source command.
Cisco SCE crashes with OSFP enabled, when second SYN packet timestamp option length is greater than ten.
The LUR reports in TB when bandwidth is around 5 Gbps for 10 minutes.
In SCOS, the packageCounterActiveSubscribers shows higher value than CLI. This issue is seen with the combination of SM and Gx for the subscriber introduction.
This section describes the open caveats pertaining to the Cisco SCE 8000 platform for Cisco SCOS Release 4.2.0:
Subscriber mapping has an extra non-mapping in the standby box.
During IPv4 and IPv6 push modes, Cisco Subscriber Manager is getting redirection RDR at the time of relogin to Cisco SCE, even though Cisco Subscriber Manager is sending redirection information for that subscriber at the time of relogin.
Subscriber flows are mapping to Not Applicable state, when bulk subscribers with multi mapping is introduced.
Flexible Redirection does not work with internal Quota provision by SCABB Quota Profile, even when subscriber gets new quota update.
Cisco SCE 8000 devices fail to validate the Include and Exclude OIDs while creating SNMP-server views.
Single mapping enforcement fails to work independently across IAPD and IANA.
If a subscriber have both IAPD and IANA mapping in the Subscriber Manager and if all the IAPD and IANA mappings are pulled into the Cisco SCE device, the Cisco SCE device contains both a single IAPD and a single IANA mapping.
When a peer is removed from a Cisco SCE device in the high-availability forwarding mode, the device fails to replace the details in the peer list automatically. As a result, the device fails to send CCRs when the primary Gy peer is removed.
In a chassis with two SCE8000-SCM modules installed, the management ports of the second SCM are active. If you plug a network cable into the management port of the SCE8000-SCM in slot 2, the Link LED turns on. The Link LED status may confuse you because this port has no IP address configured and should not be used.
The snmpget command returns the message No Such Object available on this agent at this OID even if you request for a correct OID. This issue is observed when getting the support file or when applying a policy. The issue is observed more often when you request multiple OIDs in one snmpget command.
Cisco SCE continues to generate CCR-U messages every 30 minutes for a Gx profile even after the package was changed.
The Cisco SCE 8000 crashes during Gx/Gy capacity testing while having 250,000 active sessions with long vendor specific attributes (VSA), with all VSAs being more than 200 bytes.
No SNMP trap is sent when the external-bypass command is issued on Cisco SCE 8000 GBE when the OPB-SCE8K-2L-SM optical bypass modules are installed.
Cisco SCE 8000 uses software to process the VAS, and this impacts the performance of the device. Therefore, VAS processing is not supported for delay-sensitive, bundled, flow handling.
This issue is a known limitation.
The on-failure cutoff option of the connection-mode command does not block traffic for a few minutes after the Cisco SCE 8000 is rebooted.
The notification of the first Quota Status RDR is delayed after subscriber login. Subsequent notifications come through correctly.
In the show interface linecard 0 counter command output, the DP L2TP Control Packet Count field shows DP IPv6 byte sizes. The L2TP packet count is not displayed.
The Cisco SCE 8000 platform that is configured in the IP-Tunnel L2TP Skip mode does not process traffic on the first traffic processor.
The device fails to process traffic because of bad handling of non-first-fragment packets. Therefore, in networks with some IP fragmentation, it is likely that the problem may not be observed even if IP-Tunnel L2TP Skip is configured.
The Total Link Limit feature fails on Cisco SCE 8000 devices when multiple global controllers are configured.
On Cisco SCE 8000 devices running Cisco SCOS Release 3.7.5-p1 and later, the Gy interface may be enabled after you restart the device even if the Gy interface is disabled and the configuration is saved to the startup configuration.
This issue is resolved.
Wrong value for IP_Type_TAS Count in PUR RDR when IPv6 and DS-Lite IPs are mapped to single subscriber.
