__TOC__

'''NOTE:''' Serial inline clustering between non-optimizing peers and interception ACLs were introduced in WAAS version 4.2.1. This section is not applicable to earlier WAAS versions.

==Checking for Connectivity Between the Serial Peers==

To see which devices are connected to the inline interfaces, use the '''show cdp neighbors''' command, as follows:

WAE#'''show cdp neighbors'''
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
BBSw-R32-R62 Inline 1/1/lan 154 S I WS-C3750G-Gig 3/0/17
BBSw-R32-R62 Inline 1/0/lan 154 S I WS-C3750G-Gig 2/0/18
BBSw-R32-R62 Gig 1/0 126 S I WS-C3750G-Gig 2/0/22
PLT-32-08-7301 Inline 1/1/wan 148 R 7301 Gig 0/2
PLT-32-08-7301 Inline 1/0/wan 147 R 7301 Gig 0/1
WAE-32-08-7341 Inline 1/1/wan 145 T H OE7341 Inline 1/1/w
WAE-32-08-7341 Inline 1/0/wan 145 T H OE7341 Inline 1/0/w

If the serial peers are separated by one or more switches, the peer will not show up in the output above.

==Verifying that the Serial Peers are Configured Correctly==

To verify that the serial peers are configured correctly, use the '''show peer optimization''' command, as follows:

WAE#'''show peer optimization'''
Configured Non-optimizing Peers:
Peer Device Id: 00:1a:64:c2:40:8c

Run this command on both the peers and make sure that each device shows up on the other correctly.

Use the '''show device-id''' command to check the device ID, as follows:

WAE#'''show device-id'''
System Device ID is: 00:21:5e:57:e9:d4

==Verifying that a Serial Inline Cluster is Operational==

Given the following topology example:

BR-WAE -----------WAN----------- DC-WAE2 -- DC-WAE1

or

BR-WAE1 -- BR-WAE2 -----------WAN----------- DC-WAE2 -- DC-WAE1

Normally, optimization should take place between the outermost WAEs, that is, BR-WAE and DC-WAE1, or BR-WAE1 and DC-WAE1. To ensure this, verify the device IDs on the connections by using the '''show statistics connection''' command. The PeerID on BR-WAE should indicate that it is optimizing with DC-WAE1 and the PeerID on DC-WAE1 should indicate that it is optimizing with BR-WAE.

BR-WAE#'''show statistics connection'''

The PeerID in the above output should match that of DC-WAE1.

All connections on DC-WAE2 should be in the "PT Intermediate" state.

If DC-WAE1 fails or goes into overload, new connections should be optimized between BR-WAE1 and DC-WAE2. You can verify this by using the '''show statistics connection optimized''' command on DC-WAE2. Optimized connections should be seen on DC-WAE2, with the peer ID of BR-WAE1 as the peer device.

If BR-WAE1 fails or goes into overload, there should ''not'' be optimization between DC-WAE2 and DC-WAE1. All connections should be in the "PT Non-optimizing Peer" state on DC-WAE1 and "PT No Peer" on DC-WAE2. An example of the expected '''show statistics connection''' command output follows:

DC-WAE1# '''sh stat conn'''

You can also use the Central Manager Connection Statistics report ('''''Device'' > Monitor > Optimization > Connections Statistics''') to display device connection statistics in a table, as shown in Figure 1. The Peer IDs are indicated by device name.

:'''''Figure 1. Central Manager Device Connection Statistics Report'''''

:[[Image:waast-deviceconnstats.png]]

==Detecting Serial Peer Configuration Mismatch==

Serial peers must be configured so that each is designated as a non-optimizing peer with the other. If device A is configured as a peer of B, but B is not configured as a peer of A, that is a mismatch. To discover a mismatch, you can use the Central Manager '''My WAN > Configure > Peer Settings''' page, which reports on the status of all serial peers, as shown in Figure 2. All correctly configured serial peers have a green check mark in the Mutual Pair column. Any devices without a green check mark are incorrectly configured with a serial peer that is not also configured with the device as its serial peer.

:'''''Figure 2. Central Manager Peer Settings'''''

:[[Image:waast-peersettings.png]]

To detect a serial peer configuration mismatch, you can also look for syslog messages such as the following:

%WAAS-SYS-4-900000: AD: Serial Mode configuration mismatch with peer_id=00:21:5e:27:a8:80

This error indicates that the serial peer configuration is not symmetrical on both of the peer devices.

==Troubleshooting MAPI Acceleration==

General MAPI AO troubleshooting is covered in the section [[Cisco WAAS Troubleshooting Guide for Release 4.1.3 and Later -- Troubleshooting Application Acceleration#MAPI Accelerator|"MAPI Accelerator"]] in the Troubleshooting Application Acceleration article.

The following issues can occur with MAPI acceleration on serial inline clusters:

* Outlook connection to the Exchange server is disconnected and restored
* Outlook connection to the Exchange server is disconnected and stays that way
* Outlook has problems establishing connections with the Exchange server
* Outlook connection to the Exchange server is not optimized by WAAS (either it is in pass-through or no MAPI AO optimization is done)
* MAPI escaped connections because of the EPM policy timeout in the DC WAE

===Check EPM and MAPI Dynamic Policies===

Use the '''show policy-engine application dynamic''' command to check the EPM and MAPI dynamic policies, as follows:

WAE34#'''show policy-engine application dynamic'''

===Enabling Debug Logging===

If looking at the dynamic policies and the filtering and auto-discovery statistics does not help, then enable debug logging so that a technical support engineer can troubleshoot what is happening with MAPI accelerated connections in a serial inline cluster.

Enable debugging by running the following commands:

WAE#'''debug policy-engine connection'''
WAE#'''debug auto-discovery connection'''
WAE#'''debug filtering connection'''
WAE#'''debug connection ''acl'' '''

As always, disk logging needs to be enabled and the logging level for disk has to be set to debug.

'''NOTE:''' Debug logging is CPU intensive and can generate a large amount of output. Use it judiciously and sparingly in a production environment.

==Troubleshooting Interception Access Lists==

This section describes how to troubleshoot the following problems related to interception ACLS:

* Connections are not optimized
* Connections are not being bypassed as expected

===Connections Are Not Optimized===

If connections are not optimized as expected, it could be due to the following causes.

1. The interface may be down. If it is an inline interface, all traffic will be bypassed in hardware. Use the following command to check the interface status:

WAE#'''show interface inlinegroup 1/0'''
Interface is in intercept operating mode. '''<------ Interface must be in intercepting mode'''
Standard NIC mode is off.

2. If the interface is up, check the state of the connections, and if they are in pass-through, check the reason using the following command:

WAE#'''show stat connection pass-through'''
Current Active Optimized Flows: 9004
Current Active Optimized TCP Plus Flows: 9008
Current Active Optimized TCP Only Flows: 0
Current Active Optimized TCP Preposition Flows: 0
Current Active Auto-Discovery Flows: 10294
Current Reserved Flows: 100
Current Active Pass-Through Flows: 2994
Historical Flows: 443
Local IP:Port Remote IP:Port Peer ID ConnType
155.155.14.9:21 199.199.1.200:28624 N/A PT App Cfg
155.155.13.92:21 199.199.1.147:26564 N/A PT App Cfg '''<----- Pass-through reason'''

3. If the reason appears as "PT Interception ACL", then it is due to the interception ACL denying the SYN packets.

You can look at the following output to drill down into the ACL to see which condition matched:

WAE#'''show ip access-list'''
Space available:
49 access lists
499 access list conditions
Standard IP access list test
1 permit any (1296 matches)
(implicit deny any: 0 matches)
total invocations: 1296
Interface access list references:
None Configured
''' Application access list references:
INTERCEPTION Standard test
Any IP Protocol'''

===Connections Are Not Being Bypassed as Expected===

If connections are not being bypassed as expected, make sure that the interception ACL configuration took effect using the following command:

WAE#'''show ip access-list'''
Space available:
49 access lists
499 access list conditions
Standard IP access list test
1 permit any (1296 matches)
(implicit deny any: 0 matches)
total invocations: 1296
Interface access list references:
None Configured
''' Application access list references:
INTERCEPTION Standard test
Any IP Protocol'''

Check the hit counts from the above output to see if they are incrementing as expected.

===Enabling Debug Logging===
If everything appears correct by using the commands above but there is still an issue, enable the following debug logging and look for the policy-engine decision on the SYN packet of interest.

WAE#'''debug policy-engine connection'''

As always, disk logging needs to be enabled and the logging level for disk has to be set to debug.

'''NOTE:''' Debug logging is CPU intensive and can generate a large amount of output. Use it judiciously and sparingly in a production environment.
