I'm not really sure the full detail of what is on it and if it needs to be sized cautiously.</P><P>Any advice please?</P><P>Many thanks</P> Wed, 11 Dec 2019 09:40:20 GMT Anthony_Kahwati 2019-12-11T09:40:20Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Sync-Interface-Sizing/m-p/70061#M5380 <P>Hi</P><P>I am about to build a VSX cluster and am going round in circles on the sync interface.</P><P>I've decided that it will be a port channel of 2 but I can't decide on whether it needs to be 10Gb or not.</P><P>Currently we have a VSX pair with a mix of 1Gb / 10Gb interface north and south, about 5 VS's and 2 x 1Gb for the sync and it works fine.</P><P>The new pair will have a mix of 1Gb, 10Gb, and 7 VS's and the same mix of 1Gb / 10Gb interfaces.</P><P>I am trying to decide whether I should be using 10Gb for the sync...
