Release Notes for Cisco Nexus 7000 Series Network Analysis Module (NAM-NX1) 6.0(1)
September 23, 2013, OL-30665-01
These release notes provide general information about Cisco Prime Network Analysis Module Software release 6.0(1) on the Cisco Nexus 7000 Series Network Analysis Module (NAM-NX1).
This document includes the following sections:
Network Analysis Module release 6.0(1) is for NAM-NX1 platform only. NAM-NX1 is the first Nexus 7000 service module.
Enhancements or New Features in this Release
Network Analysis Module release 6.0(1) is the first software release on the NAM-NX1 platform.
NX-OS Release 6.2(2) or later on Sup 1 and Sup 2 and Nexus 7004, 7009, 7010, and 7018 chassis.
It works with F2, F2e, M1 and M2 series line cards. It does not work with F1 series line cards. It also does not work in FCoE storage VDC.
Table 1 provides details on the NAM images available for this release on Cisco.com.
1. NAM packet decode does not provide the option to enter decode preferences and protocol forcing such as the Decode As feature seen in other products.
2. The decode filter syntax is not documented in the online help.
3. VACL capture support for NAM is not available on the Nexus 7K switch at this time.
4. When NAM monitors and captures FabricPath packets, the FabricPath header will be unconditionally removed due to a known hardware issue with F2 line cards. Although the packet data will be correctly processed and presented by NAM, the FabricPath information carried inside the header will be lost. To identify traffic that is FabricPath encapsulated, use another means such as specific VLANs or interfaces on the switch.
5. NAM correctly monitors and captures OTV, LISP, FCoE, VxLAN, VNTag, and Segment ID packets. However the performance is not optimal. An upgrade to improve the performance will be available in the near future.
6. To monitor traffic on the NAM management VLAN, you must SPAN it to data port 2.
7. The default NAM account ("guest") for CLI login has been removed due to security requirements.
8. Not all user-defined applications can be used in capture filters. This limitation applies if the application cannot be correctly identified in a single data packet.
9. Some long URLs may be truncated in the URL hit monitoring feature.
10. When performing a capture decode, you may not be able to scroll down to see all decoded packets until the entire decode is complete.
11. Configuring an unreliable or unreachable DNS server may cause some operational issues or delays on the NAM.
12. The two NAM-NX1 data ports can be combined for monitoring data but cannot be combined for packet captures. Use separate filters and capture sessions for each data port.
13. Please select the correct data port, site, and other qualifiers for your drill-down operations. In some cases, if you leave them blank, the implied/default selection may be different from your expectations.
14. Capturing packets from data port 2 to local disk works for traffic rates within the specified limit and completed sessions. Repeated start and stop of the same file-wrap session may cause data corruptions. Constant data rate higher than the disk write I/O throughput in file-wrap capture mode may also cause delay in NAM responding to Nexus 7000 supervisor, which in turn may cause the NAM to be rebooted by switch supervisor. Capture from data port 1 works fine in all cases.
15. Capturing packets to iSCSI disk and external SAS storage are not fully tested.
16. PTP/1588 time synchronization is not fully working yet.
Compatibility Testing of Supported NX-OS
Only NX-OS 6.2(2) or later is supported. There is no IOS support.
Table 2 contains the known issues for this release.
The following product documentation supports this release:
Cisco Bug Search
Bug Search Tool (BST), the online successor to Bug Toolkit, is designed to improve our customers' effectiveness in network risk management and device troubleshooting.
BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The service has provision to filter bugs based on credentials to provide external and internal bug views for the search input.
Please check out Bug Search Tools & Resources on Cisco.com. For more details on the tool overview and functionalities, check out the help page, located at http://www.cisco.com/web/applicat/cbsshelp/help.html.
