Cisco Bug: CSCvu07676 - Interface observer statistics query fails to return data in data.
Oct 03, 2020
- Cisco Nexus 9000 Series Switches
Known Affected Releases
In FX2 based ASIC platforms, we have 144 front panel ports with breakout support. However, on ASIC we have support only for 128 ports within a single bank. Symptom: Interface observer statistics query fails to return data in Cisco Nexus 9300-FX2 platform switches and Cisco Nexus 9700-FX2 line cards. 1) The input rate on ibash will be 0 irrespective of traffic flowing for affected ports. 2) moquery -d sys/phys-[eth1/15]/CDeqptIngrPkts5min - this MO would not return any values for the affected ports. There is no trigger for this issue. It is consistent across every switch. Conditions: Following ports will not have ingress packets and bytes (Unicast, Multicast and Flood) and ingress drops (forwarding, buffer, errors) populated on vsh_lc CLI. N9K-C9336C-FX2: Ports 15-18 N9K-C93300YC-FX2/ N9K-C93240YC-FX2: Ports 15,18,21,23,24 N9K-C93216TC-FX2: Ports 1-16, 51 N9K-C93360YC-FX2: Ports 16-24, 65-72 All the above mentioned ports belong to slice 1 and slice port > 54 on respective TORs.
