Field Description
Shadow 8-8-4-4-8 PXF Mtrie MTRIE lookup table index structures.
51 leaves All created leaves for all MTRIEs.
2448 leaf bytes Leaf byte counter. When a new leaf is created, the leaf byte
counter is incremented by the size of the leaf structure.
92 nodes All created nodes for all MTRIEs.
56352 node bytes Node byte counter. When a new node is created, the node byte
counter is incremented.
10 invalidations Invalidations counter. When a route (represented by a leaf) is
deleted from an MTRIE, the invalidations counter is
incremented. This counter includes all MTRIEs.
61 prefix updates IP prefix counter. When an IP prefix (represented by a leaf)
is added to the MTRIE, the IP prefix counter is incremented.
This counter includes all MTRIEs.
refcounts Counters associated with references between leaves.
3666 leaf MTRIEs have a leaf lock and a leaf free function. The leaf
lock function increments the leaf refcount. The leaf free
function decrements the leaf refcount. The leaf lock and leaf
free functions prevent a leaf from being freed (deleted) while
the leaf is still being referenced. This counter includes all
MTRIEs.
3733 node Node counter. When a child node is added to another node,
the node to which the child node is added becomes a parent
node. The node counter is decremented when a child node is
deleted. This counter includes all MTRIEs.
Prefix/Length The IP address and subnet mask of a leaf.
Refcount The number of leaves that reference a specified leaf. The
refcount counter is incremented when the leaf lock function
is called and decremented when the leaf free function is
called.
Parent When you add a less specific route to a more specific route,
the more specific route has a back pointer that points to the
less specific route.
Address The address of the memory for the specified leaf.
Shadow The shadow address in Route Processor memory for the
specified leaf.
