Cisco Cisco Expressway Release Notes
Keyword Filter for Syslog Output
You can now use keywords to filter the logs that Expressway sends to each remote syslog host. You can enter comma
delimited words or phrases, and the syslog daemon will only forward log messages that match at least one of those
keywords.

keywords.
The keyword filter gives you more control over the types of messages that are published. You may only be interested
in some types of messages, or you may not be allowed to send potentially sensitive information over the channel to
the syslog server.

The user interface has also been improved as part of this change. In addition to the new keyword filter field, we've
added more granular control over the message format and transport connection. Previously, these options were
grouped into a "Mode" field and you could not configure them unless you chose the "Custom" mode.

Notable Issues in this Version
: Upgrading Expressway to X8.7.2 breaks SSL Handshake with CUCM or IM&P 9.x
An upgrade of CiscoSSL in this version of Expressway prevents it from accepting weak DH keys. If you have not yet
applied this security improvement to your Cisco Unified Communications Manager or Cisco Unified Communications
Manager IM and Presence Service infrastructure, they may not be able to communicate securely with Expressway.
This could prevent your MRA deployment from working as expected.
