rlSpanSourceDirection
Module: CISCOSB-SPAN-MIB
OID (symbolic): CISCOSB-SPAN-MIB::rlSpanSourceDirection
OID (numeric): 1.3.6.1.4.1.9.6.1.101.219.3.1.4
Node type: OBJECT-TYPE
Type: SpanSourceDirection
Access: read-write
Description: This variable indicates the source direction for monitoring.
What is rlSpanSourceDirection?
This read-write field specifies whether a SPAN source port is mirrored for ingress traffic, egress traffic, or both. Admins care because capturing only the direction needed reduces the volume of mirrored traffic and the load on the analyzer. For example, an admin sets this to egress-only when only outbound traffic patterns need investigation, roughly halving the mirrored traffic volume compared to capturing both directions.
