Monitoring the TCP Resequencing Buffer Management Functions

Purpose

Display the configuration, current per-virtual router, and per-router state of the TCP resequencing buffer management functions. You can use the vrfName variable to specify a specific VRF for which you want to view information.

Action

To display the configuration, current per-virtual router, and per-router state of the TCP resequencing buffer management functions:

host1#show tcp resequence-buffers
TCP Resequence Buffer Management Configuration
  Global Maximum: ###
    Default Per-VR Maximum: 250
    Default Connection Maximum: 15
  This VR Maximum: 300
  This VR Connection Maximum: 15
TCP Resequence Buffer Management State
  Global buffers in use: 5
             High Water: 15
      VR Buffers in use: 17
             High Water: 32
  Buffers Discarded Because Global Limit Exceeded: 25
      Buffers Discarded Because VR Limit Exceeded: 15

Field Description

TCP Resequence Buffer Management Configuration

Global Maximum

Number of buffers that can be on the reordering queues of all connections in all virtual routers

Default Per-VR Maximum

Default maximum number of buffers for all connections in a single virtual router

Default Connection Maximum

Default maximum number of buffers for each connection in each virtual router

This VR Maximum

Maximum number of outstanding resequencing buffers in the current virtual router

This VR Connection Maximum

Maximum number of outstanding resequencing buffers on any one connection in this virtual router

TCP Resequence Buffer Management State

Global buffers in use

Total number of outstanding resequencing buffers in the router:

  • High Water—Largest number of outstanding resequencing buffers that the router has experienced since the last reset

VR Buffers in use

Number of outstanding resequencing buffers in the current virtual router:

  • High Water—Largest number of outstanding resequencing buffers for the current virtual router since the last reset

Buffers Discarded Because Global Limit Exceeded

Number of resequencing buffers discarded because the global limit was reached

Buffers Discarded Because VR Limit Exceeded

Number of resequencing buffers that have been discarded in this virtual router because the virtual router buffer limit was reached
