How to disable a port on Juniper

I will give an example of disabling/enabling a port on Juniper devices.

Configuring Syslog on Juniper

I will give an example of setting up Juniper logging to the syslog server, for convenience, to view the logs of all devices in one place, and it will also be possible to disable logging to the device’s memory to save its memory.

Warning: Host-bound traffic for protocol/exception DHCPv4:bad-packets exceeded its allowed bandwidth

Once I noticed the following warnings in the Juniper MX204 logs:

SNMP OID for Juniper QFX

I once wrote a Zabbix template for QFX5100 and will show some of the main SNMP OIDs that I used:

Configuring Juniper QFX5100

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

Configuring Juniper MX and ABillS

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

Configuring OSPF on Juniper MX

For example, I will configure OSPF on Juniper MX204.
