include in their list of subject alternate names (using either XMPPAddress or DNS formats) all of the Chat Node
Aliases that are configured on the IM and Presence servers.

Checking the Event Log
Check the Event Log on the Expressway-E for XMPP events.
Events related to XMPP federation are tagged with
Module="XMPPFederation"
. There are no XMPP-related logs on the
Expressway-C.
Performing Diagnostic Logging
When performing diagnostic logging (Maintenance > Diagnostics > Diagnostic logging), set the
develop.xcp.federation support log ( Maintenance > Diagnostics > Advanced > Support Log configuration) to
debug level.

Disabling Interdomain XMPP Federation on Unified CM IM&P
You must not enable both Interdomain XMPP Federation on Unified CM IM&P and XMPP federation on Expressway-E.
One symptom of this incorrect configuration is that some users will have one-way federation.
One symptom of this incorrect configuration is that some users will have one-way federation.
If Interdomain Federation is enabled on Unified CM IM&P, perform the following operations in exactly the order shown:
1.
Disable Interdomain Federation on the IM&P servers:
a.
Go to Cisco Unified CM IM and Presence Administration > Presence > Inter Domain Federation > XMPP
Federation > Settings.
Federation > Settings.
b.
Set XMPP Federation Node Status to Off.
2.
Refresh the set of discovered IM&P servers on Expressway-C.
3.
Restart all of the Unified CM IM&P XCP Router services that are connected to that Expressway-C.
Impact of Configuration Changes on a Live System
In general, we recommend that XMPP federation configuration changes are made 'out of hours'. This section
describes the impact that configuration changes will have on current clients using XMPP federation and any Jabber
clients using mobile and remote access.

Expressway-C Configuration Changes
Domains
Any domain configuration changes, when one or more existing domains are configured for IM and Presence services
on Unified CM or XMPP Federation will result in an automatic restart of the XCP router on both Expressway-C and
Expressway-E.

The end-user impact is temporary loss of federation and any Jabber clients using mobile and remote access will be
temporarily disconnected. The clients will automatically reconnect after a short period.
