Nov 27, 2020
- Cisco MDS 9000 NX-OS and SAN-OS Software
Known Affected Releases
Symptom: RPM performance issues seen after a npacl core. Conditions: Problem : 1 Following a core on npacl as per CSCul96643 , we see a lot of rpm \ issues. Also, the fix seems to be present on 6.2.8a but doesn't seem to be a \ correct fix. hence this has to be validated. We expect following any core the process has to gracefully start and should not \ affect further. Problem 2 : I have 250 IPv4 ACL, 250 IPv6 ACL, 250 route maps and 250 SVI configs .... Afte that I am modifying the ACL policy multiple times .. "ipaccess-list PBR_ACL_1 " "10 pemit ip 126.96.36.199/8 188.8.131.52/8" Doing above multiple times and Modifying the PBR ACL A saw the crash after doing that and then removing the SVI from the configs . Root Cause/Fix : When trying to modify existing route-map policy or adding \ route-map plociy, npacl core multiple places while trying to free the old policy \ tree . For route-maps we do not need to delete the entire tree policy and have to \ retain old(tree ptr) and new if-else nodes(ptr) should append to old tree ptr.
