本文介绍如何排除WAAS Express操作故障。
WAAS Express是内置在路由器等设备上运行的IOS中的WAAS功能。WAAS Central Manager可以管理WAAS Express设备以及WAAS网络中的其他WAAS设备。本文介绍如何排除WAAS Express设备运行故障。
注意:WAAS 4.3.1版中引入了WAAS Express Central Manager支持。本部分不适用于早期的WAAS版本。
要验证WAAS Express映像版本,请在WAAS Express路由器上使用show waas status命令。要从WAAS Central Manager查看WAAS Express映像版本,请选择“我的WAN”>“管理设备”。
waas-express# show waas status IOS Version: 15.1(20101018:232707) <----- IOS version WAAS Express Version: 1.1.0 <----- WAAS Express version . . .
WAAS Express许可证有两种变体:评估许可证(有效期为12年)和永久许可证。在WAAS Express设备上使用show waas status命令显示许可证信息。
waas-express# show waas status IOS Version: 15.1(20101018:232707) WAAS Express Version: 1.1.0 . . . WAAS Feature License License Type: Evaluation <----- Indicates an evaluation license Evaluation total period: 625 weeks 0 day Evaluation period left: 622 weeks 6 days
在WAAS Express设备上使用show waas status命令列出启用WAAS的接口集。此命令还显示设备支持的优化类型。某些WAAS Express路由器型号不支持DRE。
waas-express# show waas status IOS Version: 15.1(20101018:232707) WAAS Express Version: 1.1.0 WAAS Enabled Interface Policy Map GigabitEthernet0/1 waas_global <----- Interfaces on which optimization is enabled GigabitEthernet0/2 waas_global Virtual-TokenRing1 waas_global Virtual-TokenRing2 waas_global GigabitEthernet0/0 waas_global Virtual-TokenRing10 waas_global WAAS Feature License License Type: Evaluation Evaluation total period: 625 weeks 0 day Evaluation period left: 622 weeks 6 days DRE Status : Enabled <----- Indicates DRE is supported LZ Status : Enabled + Entropy Maximum Flows : 50 <----- Number of optimized connections supported Total Active connections : 0 <----- Total number of connections active Total optimized connections : 0 <----- Total number of optimized connections
注意:WAAS应仅在WAN接口上启用。如果要优化的连接通过多个WAN接口路由,则WAAS应应用于所有这些WAN接口。
注意:如果在逻辑或虚拟接口上启用WAAS,则无需在相应的物理接口上实施。
在WAAS Express设备上,使用show waas connection命令列出优化连接集。直通连接不包括在内。
waas-express# show waas status ConnID Source IP:Port Dest IP:Port PeerID Accel 1999 64.103.255.217 :59211 192.168.4.2 :1742 0021.5e57.a768 TLD <----- TFO, LZ and DRE are applied 1910 64.103.255.217 :56860 192.168.4.2 :61693 0021.5e57.a768 TLD 1865 64.103.255.217 :59206 192.168.4.2 :23253 0021.5e57.a768 TLD
要从Central Manager查看类似信息,请选择WAAS Express设备,然后选择Monitor > Optimization > Connections Statistics以查看“Connections Summary”表。
在WAAS Express设备上,使用show waas statistics application命令列出分类到每个应用的优化数据。WAAS Express设备不显示直通数据。此数据用于在WAAS Central Manager中生成TCP相关图表。
waas-express# show waas statistics application Number of applications : 1 Application: waas-default TCP Data Volumes Connection Type Inbound Outbound Opt TCP Plus 53001765483 41674120 Orig TCP Plus 0 87948683030 Opt TCP Only 1165 863 Orig TCP Only 60 0 Internal Client 0 0 Internal Server 0 0 TCP Connection Counts Connection Type Active Completed Opt TCP Plus 50 126 Opt TCP Only 0 71 Internal Client 0 0 Internal Server 0 0 Pass Through Connection Counts Connection Type Completed PT Asymmetric 0 PT Capabilities 0 PT Intermediate 0 PT_Other 0 Connection Reset: 0 Cleared connections 0
在WAAS Express设备上,使用show waas alarms命令列出设备中存在的警报及其状态。
waas-express# show waas alarms WAAS status: enabled Alarms Connection limit exceeded: on <----- on indicates this alarm is active. off indicates inactive Too many peers discovered: off WAAS license expired: off WAAS license revoked: off WAAS license deleted: off High CPU: off
要从中央管理器查看所有设备的警报,请选择“我的WAN”>“警报”。除上述警报外,如果WAAS Express和WAAS Central Manager设备的时钟不同步,还会发出警报。
在WAAS Express设备上,使用show waas statistics peer命令列出WAAS Express设备的对等设备。
waas-express# show waas statistics peer Number of Peers : 1 Peer: 0021.5e57.a768 TCP Data Volumes Connection Type Inbound Outbound Opt TCP Plus 597068158 5212151 Orig TCP Plus 0 6867128187 Opt TCP Only 0 0 Orig TCP Only 0 0 Internal Client 0 0 Internal Server 0 0 TCP Connection Counts Connection Type Active Completed Opt TCP Plus 50 0 Opt TCP Only 0 0 Internal Client 0 0 Internal Server 0 0 Pass Through Connection Counts Connection Type Completed PT Asymmetric 0 PT Capabilities 0 PT Intermediate 0 PT_Other 0 Connection Reset: 0 Cleared connections 0 Router#show waas statistics aoim Total number of peer syncs: 1 Current number of peer syncs in progress: 0 Number of peers: 1 Number of local application optimizations (AO): 3 Number of AO discovery successful: 1 Number of AO discovery failure: 0 Local AO statistics Local AO: TFO Total number of incompatible connections: 0 Version: 0.11 Registered: Yes Local AO: HTTP Total number of incompatible connections: 0 Version: 1.1 Registered: Yes Local AO: SSL Total number of incompatible connections: 0 Version: 1.0 Registered: Yes Peer AOIM Statistics Number of Peers : 1 Peer: 0027.0d79.c215 <--- Peer ID Peer IP: 20.0.0.2 <--- Peer IP Peer Expiry Time: 00:00:02 Peer Compatible: Yes Peer active connections: 0 Peer Aoim Version: 1.0 Peer sync in progress: No Peer valid: Yes Peer Software Version: 4.4.3(b4) Peer AOs: Peer AO: TFO Compatible: Yes Version: 0.20 Peer AO: HTTP Compatible: Yes Version: 1.4 Peer AO: SSL Compatible: Yes Version: 1.0 Router#show waas statistics dre peer DRE Status: Enabled Current number of connected peers 0 Current number of active peers 1 Peer-ID 0027.0d79.c215 <--- Peer ID Hostname waasx1-b-wae.cisco.com <--- Peer hostname IP reported from peer 20.0.0.2 <--- Peer IP Peer version 4.4.3(b4) Cache: Cache in storage 0 B Age 00:00:00 AckQ: AckQ in storage 0 B WaitQ: WaitQ in storage 0 B WaitQ size 0 B Sync-clock: Local-head 0 ms Local-tail 0 ms Remote-head 18609143000 ms Curr-sync-clock 24215235228 ms Encode Statistics DRE msgs: 1 R-tx total: 0 R-tx chunk-miss: 0 R-tx collision: 0 Bytes in: 0 Bytes out: 0 Bypass bytes: 178 Compression gain: 0% Decode Statistics DRE msgs: 4 Bytes in: 299 Bytes out: 277 Bypass bytes: 51 Compression gain: 0% Nacks generated: 0
要从Central Manager查看类似信息,请选择“监控”>“拓扑”。
由于以下问题,WAAS Express设备可能会在中央管理器中进入脱机状态:
要验证WAAS Express设备上的HTTPS服务器配置,请使用show ip http server secure status命令。
waas-express# show ip http server secure status HTTP secure server status: Enabled HTTP secure server port: 443 HTTP secure server ciphersuite: 3des-ede-cbc-sha des-cbc-sha rc4-128-sha HTTP secure server client authentication: Disabled HTTP secure server trustpoint: local HTTP secure server active session modules: ALL
此版本的WAAS-Express支持传输优化,包括TFO、LZ和DRE。
WAAS-Express版本1.0在IOS软件版本15.1(3)T1中引入
WAAS-Express版本1.5在IOS软件版本15.1(4)M中引入。除优化外,此版本还增加了对称为性能代理(PA)的嵌入式监控功能的支持。 有关PA的详细信息,请参阅CCO上的PA页面

WAAS CM和WAAS-Express时钟需要同步,因此强烈建议将NTP服务器配置为同步时钟。
使用show waas statistics pass-through验证传递统计信息/原因。查找连接为何通过的原因。

检查自动发现统计信息(和/或使用自动发现调试)。

这通常是由配置错误引起的。WAAS-Express版本2映像中默认禁用HTTP-Express加速器和CIFS-Express加速器。请检查Express加速器是否全局启用。

在测试期间,可能已发现路由器崩溃和回溯。搜索以前的案例和DDTS以查找类似的已知问题。此外,我们还需要隔离导致崩溃的功能。如果IOS功能(ios-waas或第4层转发除外)导致崩溃/回溯,则应相应联系该特定功能开发团队/路由器TAC。
性能下降可能由多种原因引起:流量的性质、路由器上的负载、网络拓扑或网络中的数据包丢弃。要处理慢速连接,我们需要确定直通或未优化连接的相对降级。
注意:不支持每数据包负载共享。这不是默认负载共享模式。
挂起连接没有已知问题,请向开发团队提供以下信息,帮助RCA解决问题。

如果WAAS-Express设备在WCM上的设备组之间移动,则有时会看到新设备组下的策略定义不生效。当设备从设备组中取消分配时,它从备份策略集获取设备最后拥有的策略。
在设备组之间移动设备时,请执行以下步骤:
* Go to the Policy Definitions page of that device and select the new device-group and click on Submit. OR * Go to device-group-1 -> Assign Devices page and unassign the device from this DG. * Go to device-group-2 -> Assign Devices page and assign the device to this DG. * Go to device-group-2 -> Policy Definitions page and click on 'Force DG settings' button.
此区域没有已知问题。请按照以下步骤收集日志,并将其提供给开发团队。
* Disable waas on Waas-Express device * Clear statistics on WAAS-Express and core WAE * Enable waas on Waas-Express device * Let traffic run, disable waas on Waas-Express device * Collect statistics * Present screen-shots and show command outputs.

要调试连接问题,您可能需要捕获WAAS Express设备上的数据包。
