csOrionVrSpfTcpInitTblSize
Module: COSINE-ORION-MIB
OID (symbolic): COSINE-ORION-MIB::csOrionVrSpfTcpInitTblSize
OID (numeric): 1.3.6.1.4.1.3085.3.1.6.20.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This Size puts an upper limit on the number of TCP sessions that can remain in the SYN state at any given time, this limits the ability to accept new TCP connections simultaneously.
What is csOrionVrSpfTcpInitTblSize?
This read-write Integer32 (1-1000) limits how many TCP sessions can sit in the SYN (half-open) state at once, which in turn caps how many new TCP connections can be established simultaneously. An admin tunes this to balance protection against SYN-flood style resource exhaustion against legitimate bursts of new connections. For example, a VR fronting a busy web service that suddenly can't accept new TCP connections during a traffic spike may need this init table size increased.
Examples
