Release Notes

Cisco Nexus 3500 Series NX-OS Release Notes, Release 6.0(2)A6(7)

Limitations

The following are the known limitations for Cisco NX-OS Release 6.0(2)A6(7):

■ IGMP packets, which are filtered by report policies on the local switch on which IGMP filtering is enabled, will

still get forwarded to the peer switch (See CSCup50141).

■ Counters for the warp SPAN destination port do not work. To check these counters, connect another switch to

the destination ports (See CSCuq66372).

■ In a vPC setup, because of a hardware limitation, non-RPF traffic for (S,G) that comes in on the RPF interface for

(*,G) hits the (*,G) entry instead of being treated as (S,G) non-RPF traffic and dropped. (S,G) non-RPF traffic is

then incorrectly forwarded by (*,G) entry, thus causing traffic duplication. To avoid duplication of Layer 3

multicast traffic by sending the (S,G) RP-bit prune, run the ip pim pre-build-spt command (See CSCun34760).

■ While performing Online Insertion Removal (OIR) on the cable or optics of a 40G bundle, you must perform the

following sequence of steps for the OIR to be successful (See CSCuq93225):

1 Disable (shut) the 40G port

2 Change the speed from 40G to 10G

3 Perform an OIR on the cable or optics

4 Change the speed from 10G to 40G

5 Re-enable (no shut) the port

Best Practices

The syntax of the poap_script.py file should be validated using the python validation tool before using the file for POAP.

Otherwise, if the poap_script.py file is edited with a syntax error, the POAP process will exit without giving an error.

MIB Support

The Cisco Management Information Base (MIB) list includes Cisco proprietary MIBs and many other Internet Engineering

Task Force (IETF) standard MIBs. These standard MIBs are defined in Requests for Comments (RFCs). To find specific

MIB information, you must examine the Cisco proprietary MIB structure and related IETF-standard MIBs supported by the

Cisco Nexus 3000 Series switch. The MIB Support List is available at the following FTP sites:
