gmplsOutSegmentTTLDecrement
Module: GMPLS-LSR-STD-MIB
OID (symbolic): GMPLS-LSR-STD-MIB::gmplsOutSegmentTTLDecrement
OID (numeric): 1.3.6.1.2.1.10.166.15.1.3.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-create
Description: This object indicates the amount by which to decrement the Time to Live (TTL) of any payload packets forwarded on this segment if per-hop decrementing is being done.
A value of zero indicates that no decrement should be made or that per-hop decrementing is not in use.
See the gmplsTunnelTTLDecrement object in the gmplsTunnelTable of GMPLS-TE-STD-MIB for a value by which to decrement the TTL for the whole of a tunnel.
This object cannot be modified if mplsOutSegmentRowStatus for the associated entry in the mplsOutSegmentTable is active(1).
What is gmplsOutSegmentTTLDecrement?
This value sets how much the TTL of forwarded payload packets is decremented as they traverse this outgoing segment, when per-hop TTL decrementing is in use; a value of zero means no decrement is applied, or that per-hop decrementing isn't in use on this segment. An admin configures this to control TTL/hop-count visibility for traceroute-style diagnostics across GMPLS tunnels, distinct from the whole-tunnel TTL decrement configured elsewhere in GMPLS-TE-STD-MIB. For example, setting this to 1 makes the segment behave like a normal IP hop for TTL purposes, while leaving it at 0 makes the segment effectively invisible to hop-count-based tools.
