Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to bypass authentication controls or to create a denial of service (DoS) condition. On April 7, 2015, NTP.org and US-CERT released a security advisory dealing with two issues regarding bypass of authentication controls. These vulnerabilities are referenced in this document as follows: CVE-2015-1798: NTP Authentication bypass vulnerability CVE-2015-1799: NTP Authentication doesn't protect symmetric associations against DoS attacks Cisco has released software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

Known Bugs - Network Convergence System 6000 Series Routers Alert Type: Updated * Bug Id: CSCuu89754 Title: Bundle with aggressive LACP timer flapped on (un)shut of slice on lc Status: Fixed Severity: 2 Severe Description: Symptom: Bundle links configured with LACP aggressive timer from slice1 flapped while trying to bring up slices 0,2,4 on LC3 Conditions: Bundle links configured with LACP aggressive timer from slice1 flapped while trying to bring up slices 0,2,4 on LC3 Workaround: None Further Problem Description: Last Modified: 02-SEP-2015 Known Affected Releases: 5.2.5.BASE Known Fixed Releases: * 5.2.5.22i.FWDG, 6.0.0.13i.FWDG Alert Type: Updated * Bug Id: CSCus64684 Title: NCS6K FIA drop - ingress interface and egress bundle share same slice Status: Terminated Severity: 2 Severe Description: * Symptom: NCS6K FIA drop - ingress interface and egress bundle share same slice Conditions: Traffic overloading specific interface Workaround: Readjust bundle config and/or traffic profile Further Problem Description: While generating IXIA traffic flows, we identified packet drops when two flow are on at the same time. These flows are concurrent in the same slice 0 location 0/3/cpu0 (income interfaces hun0/3/0/0 and hun0/3/0/1). Flow 1 - Ingress hun0/3/0/0 and egress bundle containing hun0/3/0/6 (slice 3) Flow 2 - Ingress hun0/3/0/1 and egress hun0/3/0/7 (slice 3) If we start flow-2, 95% line-rate 500 bytes per packet, the packet loss is zero. When we start flow-1 after flow-2, 95% line-rate 500 bytes per packet, flow-2 is impaired with packet loss. We also noticed that if we increase packet size to 1500 bytes, the drops do not occur. On debugging the issue we found out that one of the bundle members is 0/3/0/6 which is on the same asic as the destination port of flow 2 0/3/0/7. In the working case amba requires 130G of credits to send out 95G of unicast traffic. However we see that when 0/3/0/6 is a member of the bundle, 0/3/0/7 issues only 112G of credits which leads to the drops in the stream going out of 0/3/0/7. At this time there was around 9G of traffic egressing out 0/3/0/6. Looking at the voq state of interface 0/3/0/7 we saw that the queue was predominantly in the off state most of the time the traffic was running. We tested by removing 0/3/0/6 from the bundle and did not see any drops Last Modified: 28-SEP-2015 Known Affected Releases: 5.2.1.CE Known Fixed Releases: Alert Type: Updated * Bug Id: CSCuw20165 Title: bfd agent crashed while ISSU and ISSU aborted Status: Fixed Severity: 2 Severe Description: * Symptom: bfd agent crash will be seen.

This could occur in any MC Panini setup. Program terminated with signal 6, Aborted. #0 0x00007f6bfd6265b5 in raise (sig=) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64 64 return INLINE_SYSCALL (tgkill, 3, pid, selftid, sig); Conditions: This issue can occur Reload/Insersion of FC Workaround: none Further Problem Description: This is caused in the scenario at boot up when if links are down, then the genem lanes associated with that link need to be reset. This issue is caused at the time of genem lane reset. Fixed it in r52x (5.2.5) Last Modified: 25-SEP-2015 Known Affected Releases: 5.2.5.BASE Known Fixed Releases: 5.2.5.22i.BASE Alert Type: Updated * Bug Id: CSCuv17443 Title: ISSU load fails when eoam configured on 50+ interfaces of NCS6k LC Status: Fixed Severity: 2 Severe Description: Symptom: ISSU load fails with the following error 'The user attempted to configure 802.3 OAM beyond supported per linecard scale: Only 100 interfaces supported per card' Even though the user does not have more than 100 interfaces configured for link-oam Conditions: The user has more than 50, but less than 100, interfaces configured to run link-oam on one card. The user is running ncs6k versions 5.2.3 or 5.2.4. (No other releases or platforms are affected). Workaround: There is no true workaround. The user will have to remove enough link-oam configuration to reduce the link-oam configured interface count to below 50 before running an ISSU install Further Problem Description: This issue only occurs if the ethernet_link_oam_daemon process gets a checkpoint IDT update before the initial configuration update from sysdb during ISSU. If the events occur in the opposite order, ISSU will succeed.

Conditions: If the slice corresponding to physical interface(s) which are part of bundle, bundlemgr_ea process crashes. Note that this issue is not always reproducible. The following scenarios may trigger the bundlemgr_ea process crash: 1. Slice shut/mode change using CLI (hw-module loc <> slice breakout | framer-mode | reset | shutdown) 2. Commit replace of the configuration Workaround: LC reload. Further Problem Description: The problem may not be hit always. It happens when there is a delay of about 60 seconds in processing of bundle member removal by bundlemgr_ea causes race condition between access of interface information by bundlemgr_ea process and deletion of interface information by intf_ea process.

For LED, it has led stream which send to CCC FPGA. The main bit we need to check from CCC FPGA 0x402C is bit 0, bit 4 which are link state of both QSFP port, bit 12 and bit 16 are activity state of QSFP port. So we monitor the bit stream as well as clk and enable pin. Looks like enable ping set high once clk pass 24 cycle. And data looks correct, bit 0,4 set low and bit 12,16 sometimes low sometimes high since activity led blink. But HW folks said data pin follow clk falling edge. Then it's not correct. Invert the clk and data is correct then.
