Description: Number of all TCP connections.
What is zxAnSecL3TcpTotalConns?
This read-only counter reports the total number of TCP connections currently tracked by the device. Admins use it as the denominator, alongside zxAnSecL3TcpHalfOpenConns, to gauge what proportion of current connections are stuck in a half-open state during SYN-flood monitoring. For example, a total connection count that spikes sharply alongside a rising half-open count would point to an active SYN-flood attack rather than normal traffic growth.
