Solution BUG: Bad page state in process kworker

Once I assembled a new access server with Accel-ppp and Intel XL710 network adapters, and after putting it into operation, I noticed that all processor cores are used evenly, and the tenth core is used almost 100%, and I also noticed messages in the logs:

SNMP OID for Netman 102 plus

Once I needed to create a template in Zabbix to monitor Netman 102 plus, I will describe which SNMP OIDs I used.

Alarm LASER_ALWAYS_ON from OLT 0x03000000 port EPON0/X

Once I noticed in the BDCOM P3608-2TE logs:

Configuring Juniper QFX5100

For example, I will configure the Juniper QFX5100-24Q-AFO switch.

linkFlapErrDisabled on Cisco Nexus

I once noticed that the port is periodically disconnected on the Cisco Nexus N3K-C3064PQ-10GX switch, there are a lot of records in the logs that the link was falling and rising, I looked at the status of the port:

Huawei S3928P-EI firmware update

I will give an example of updating the firmware of the Huawei Quidway S3928P-EI switch.

Reboot iLO via SSH

Once I tried to open the iLO5 web interface on the HP DL380 Gen10 server and it did not open, hung on the login and password entry page, or immediately after it, iLO5 version was 2.63.

Configuring Juniper MX and ABillS

For example, I will configure the Juniper MX204 to work with the ABillS billing system.

Juniper. Configuring RPF in Dynamic Profiles

For example, I will configure unicast RPF (reverse-path forwarding) on Juniper MX204.
RPF allows you to reduce the impact of DOS-type attacks on IPv4 and IPv6 interfaces.

Configuring iBGP on Juniper MX

For example, I will configure Internal BGP on Juniper MX204. Since there are servers with Accel-ppp (ipoe) in the network and you need to balance users between these servers and Juniper, iBGP will transfer user routes with /32 mask from all devices to the main router/routers. iBGP is also needed when there are several links to Uplink providers that are connected to different routers, then you need to configure iBGP between these routers.
