Cisco Cisco Expressway Manuel De Maintenance
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.

If Interdomain Federation is enabled on Unified CM IM&P, perform the following operations in exactly the
order shown:
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
.
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.

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.

This will remove the Expressway-E XMPP federation node from all discovered IM&P servers. A
notification will appear on the IM&P administration interface to restart the XCP router on all affected IM&P
nodes.

The end-user impact is that all IM&P sessions will be disconnected. That is, there is a loss of federation,
IM&P sessions over mobile and remote access will be disconnected, and sessions directly homed on the
IM&P node will be dropped. When the XCP router is restarted on each IM&P node, all XCP functionality
on that node will be disrupted.
