  • Cisco MDS 9000 NX-OS and SAN-OS Software

Known Affected Releases

6.1(2) 6.2(6)S1 6.2(6a)S12

Description (partial)

Symptom:
In N7K, ToS to CoS mapping does not work in extended ping although catalyst can do the mapping. If ToS value is set to 32 or bigger, it is mapped to CoS value other than 1. But NX-OS does not have such functionality, therefore CoS value in a frame of the extended ping is 0.

Conditions:
ToS is set to 32 or bigger to map the first 3 bits to CoS value.
