Bug ID 

Description 

When removing the secondary IP on an external SVI interface, static routes defined in the VRF, or context 
of the SVI, are removed causing traffic to be looped in the fabric. 

The N9K-C9372 Inlet sensor reports invalid high temperature data. This will raise faults, such as the 
sensor temperature crossing the minor/major threshold. 

After setting up a SYSlog server, the server which shows many messages with "CDP interface is DOWN" 
on the server interfaces when the CDP policy is not configured (that is, it is DISABLED). 

Even though it is configured on the route control profile, which is defined to set type-1, when a border leaf 
reboots, it advertises with type-2 (the default option). 

If you have an AVS attached to a pair of leafs through a 

Virtual Private Cloud

, if you reload one leaf, some 

traffic flow from a virtual machine that is located on the AVS can be dropped by the ACI leaf for up to 5 
minutes. This is seen just after the reloading leaf is back online. 

Leaf fan failure faults are spuriously raised and then cleared (within 30 seconds). 

Interface becomes stuck configured with incorrect speed. 

The Front vs Rear Threshold should reflect the fan specifications. For example: 



 

For RED labeled fans and power supplies, the Front Sensor Threshold should be less than Rear 
Sensor Threshold. 



 

For Blue labeled fans and power supplies, the Front Sensor Threshold should be more than Rear 
Sensor Threshold. 

We should have higher threshold on the front sensor, because Blue Fan airflow is from rear to front. With 
Blue Fan cold air is coming over the rear sensor and hot air is exhausted over the front sensor. This can 
result in the following Temperature alarms: 

%PLATFORM-1-PFM_ALERT: Mod 1 sensor X has minor temp alarm 

An alert triggers for /var/log high usage even though usage remains below the trigger threshold. 

While migrating a subnet from an external firewall to a bridge domain on ACI, all 4 leaves crash at the 
same time at EPMC.
