What is agentSwitchDenialOfServiceL4PortMode?
This read-write toggle enables or disables the switch's Layer 4 Port denial-of-service protection feature. Admins turn this on to have the switch block packets where the source and destination TCP or UDP port numbers match, a known DoS technique against certain OS network stacks. Setting agentSwitchDenialOfServiceL4PortMode to enable(1) causes the switch to drop a packet whose source port and destination port are both, for example, 135.
