NSX Lastline - Sensor with Broadcom Interfaces in an error state

Products

• VMware vDefend Network Detection and Response

Issue/Introduction

Appliance is not pingable or does not have network connectivity

lastline_apply_config logs displays the lines :

 INFO - Error: Evaluation Error: Error while evaluating a Function Call, Non-existing interfaces configured as sniffing interface: enp59s0f0np0,enp59s0f1np1 (file: /usr/share/appliance-config/modules/sensor/manifests/common.pp, line: 116, column: 9) on node lastline-sensor.lastline.local

ERROR - Applying configuration failed. 2022-10-18 09:48:57,956: output: Applying configuration failed.

 

lastline_test_appliance displays the error :

output: > The system found unexpected settings. Please remove any configuration changes that were applied manually and retry: [('customer_configs.sniff_ifaces', ValidationError('Interface enp59s0f0np0 does not exists',))]

Environment

NSX NDR ( LASTLINE)

Cause

Instability in the Broadcom driver fails to load after a kernel update.

Resolution

The issue can impact both Management and Sniffing interfaces. 

Upon validation of the sniffing interfaces configuration file vs the NICS in the appliance , we see device names are missing in the  Device Section for the Broadcom NetXtreme Interfaces  :

Executing cat /etc/previct_config/sniff_ifaces as current user
2022-10-18 10:59:23,400: output: enp59s0f0np0,enp59s0f1np1

 

Executing lshw -c network -short as current user

output: H/W path       Device           Class     Description

output: ========================================================

output: /0/100/1c.5/0     eno1        network    NetXtreme BCM5720 Gigabit Ethernet PCIe

output: /0/100/1c.5/0.1   eno2        network    NetXtreme BCM5720 Gigabit Ethernet PCIe

output: /0/101/0                              network    BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller

output: /0/101/0.1                           network    BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller




The missing device name points to a potential driver issue and below are the steps to reinstall the drivers :
 

1. Run dkms status

Verify you see 1.10.0-214.0.259.0 in the output if this version # is different, you need to change the version # below in Step # 2.

2. Run dkms remove bnxt_en/1.10.0-214.0.259.0 --all

3. Run dkms build bnxt_en/1.10.0-214.0.259.0 -k

4. Run dkms install bnxt_en/1.10.0-214.0.259.0 -k

5. Run modprobe bnxt_en

• No output is expected from this command

6. Run lshw -c network -short | less

• Verify you now see device names next to BCM57414 interfaces

7. Re-trigger the configuration.

The above steps also holds good if the issue is seen on Management Interfaces which are using Broadcom Cards.
