【分享】思科WAAS加速设备中show statistic connection流加速状态解释

大家好。在我们平时使用WAAS设备时候通常要使用命令show statistic connection来查看到各种流量加速的状态。但是经常会发现有各种各样的结果并不清楚是什么意思。这种情况下,我们可以对照下面的表来对不同的connection状态做一个了解:

ConnType
Description
Accelerator Non-Optimized
The connection has been initiated from an external client to an external server and is not optimized.
Accelerator Optimized
The connection has been initiated from an internal client to an external server and is optimized.
App Dyn Mtch Non-Optimized
The connection has been forced through an application dynamic match and is non-optimized by an application accelerator, even though the connection may be optimized by TFO+DRE+LZ.
App Dyn Mtch Optimized
The connection has been forced through an application dynamic match to be optimized, even though the connection may be handled as pass-through.
PT AD Int Error
The connection encountered an internal error during processing by the TFO auto discovery SYN cache.
PT App Cfg
The policy action for this application is configured as pass-through.
PT App Override
The connection is pass-through because the internal application has explicitly requested that the connection not be optimized. This state would only occur if the connection would have otherwise been optimized.
PT Asym Client
The connection is pass-through due to the WAE only seeing one side of the TCP connection (where the src is the client and the dst is the server).
PT Asym Server
The connection is pass-through due to the WAE only seeing one side of the TCP connection (where the dst is the client and the src is the server).
PT Dst Cfg
The policy action for this application is configured as pass-through in the peer WAE.
PT FB Int Error
The connection encountered an internal error during processing by the filter bypass module.
PT_Glb Cfg
The global action is configured as pass-through; that is, TFO, DRE, or LZ are disabled globally on the WAE.
PT In Progress
The connection was already established when the first packet was seen by the WAE.
PT Interception ACL
The connection is pass-through due to an interception ACL denying optimization.
PT Intermediate
The connection is pass-through due to the WAE being in the middle of the best local and remote WAE's (relative to the client and server).
PT No Peer
The connection is pass-through due to no peer WAE being found during TFO auto-discovery.
PT Non-Optimizing Peer
The connection is pass-through because the only peer found is a serially clustered peer and optimization is disabled to the peer.
PT Overload
The TFO application has indicated it is overloaded (that is, the maximum number of optimized connections has been exceeded). New connections not handled by an application accelerator are configured as pass-through.
PT PE Int Error
The connection encountered an internal error during processing by the policy engine.
PT Rjct Capabilities
The connection is pass-through due to auto discovery finding that the peer WAE does not have the required capabilities.
PT Rjct Resources
The connection is pass-through due to auto discovery finding that the peer WAE does not have the required resources.
PT Server Blacklist
The connection is pass-through because the server is on the TFO blacklist as not supporting TCP Option (0x21) being present in the SYN packet.



希望这个表格能帮助大家了解connection的加速状态。
