show ddos-protection protocols parameters
Syntax
show ddos-protection protocols <protocol-group> parameters<brief | detail | terse>
Description
Display DDoS protection configuration information for all protocol groups or for a particular protocol group.
Starting in Junos OS Release 22.3R1, on MX Series
and EX9200 Series devices, we’ve updated the default bandwidth value from 20000 to 100 pps
and burst policer value from 20000 to 100 packets. This enhancement avoids the CPU usage of
eventd and snmpd reaching more than 100%. Earlier to
this release, when the system receives a violated traffic for SNMP along with other
protocols traffic, the CPU usage of eventd and snmpd was
reaching more than 100% with an error.
Options
| none | Display information for all protocol groups. |
| brief | detail | terse | (Optional) Display the specified level of output.
|
| protocol-group | (Optional) Display information for a particular protocol group. See show ddos-protection protocols for a list of available groups. |
