Smart Licensing Using Policy

Smart Licensing Using Policy (SLP) is an enhanced version of Smart Licensing, which provides a licensing solution that does not interrupt the operations of your network and to enable a compliance relationship to account for the hardware and software licenses you purchase and use. SLP solution provides a seamless experience with various aspects of licensing such as purchase, use, report license usage to CSSM through Resource Utilization Measurement (RUM) report, and reconciliation. The only enforcement type supported is Unenforced or Not Enforced on Cisco Nexus 9000 and 3000 platform switches.

For more information see, Cisco Nexus Smart Licensing Using Policy Guide, Release 10.2(x).

Headline: N3500 does not bring link up with Finisar transceiver after upgrade to converged code

Symptoms: Link with Finisar transceiver does not come up.

Workarounds: N/A

CSCvz22691

Headline: N3500 interfaces may stop processing rx traffic after connected host NIC flaps

Symptoms: N3500 interface rx counters are not incrementing.

Workarounds: Reload ascii of N3500.

CSCvx04275

Headline: Nexus 3000: Upgrade from 6.0(2)U6(x) to 7.0(3)I7(x) causes port-channel config to be missing

Symptoms: Physical members of port-channel interfaces will be missing their "channel-group...." configuration post-upgrade. Accounting log post-upgrade shows FAILURE when configuration replay is attempted by the Nexus device.

Workarounds: Re-configure speed/duplex for the member interfaces and re-add channel-group config post-upgrade. Alternatively, you can upgrade to 7.0(3)I4(6) first, then jump to 7.0(3)I7(x). Issue does not seem reproduce-able then.
