Can someone put some light on TCP version?</P> Tue, 12 Mar 2019 08:21:08 GMT ankit.dhawan 2019-03-12T08:21:08Z https://community.cisco.com/t5/network-security/asa/m-p/2963540#M149495 <P>What's the use of TCP version of port 514?

Nowadays it should not be relevant any more for general use.</P> Mon, 03 Oct 2016 20:53:11 GMT https://community.cisco.com/t5/network-security/asa/m-p/2963541#M149496 Karsten Iwen 2016-10-03T20:53:11Z https://community.cisco.com/t5/network-security/asa/m-p/2963542#M149497 <P>Ankit,</P> <P></P> <P>As karsten pointed out TCP 514 was used by Remote Shell and nowadays few online games work on TCP 514.</P> <P>UDP 514 is still used for syslog purpose.</P> <P></P> <P>However, many network devices now prefer TCP based sysloging, so there is an option where one can just mention which protocol to use, if you mention TCP without giving a port, it by default takes TCP 514. ASA is an example of this.</P> <P></P> <P>Hope this helps,</P> <P>Pulkit</P> <P></P> Tue, 04 Oct 2016 13:19:36 GMT https://community.cisco.com/t5/network-security/asa/m-p/2963542#M149497 Pulkit Saxena 2016-10-04T13:19:36Z
