Hello,

 

Recently we encountered bug, where our system (Nexus 9372PX-E) crashed after we configured more than 256 port-channels. The bug id is here: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCve20830/

 

maybe someone know how much port-channel in FEX topology is supported by N9K boxes ? seems it's different than in documentation.

Hi,

Have a look at this link. The 9732 is listed as not supporting any FEX.

sorry, it's 9372.

by the way. Is there any command to check TCAM utilization ? According to port-channel usage ?
