https://community.extremenetworks.com/t5/extremeswitching-exos-switch/gptp-switch-becoming-the-master-of-both-sides/m-p/77290#M19564 Hi, <BR /> I'm using x430-8p switch, connected to two PCs that use the OpenAvnu AVB implementation. <BR /> AVB is enabled in the switch. <BR /> My question is regarding the gPTP protocol- the computer in both sides appear to have the switch itself as a grandmaster. <BR /> Does the switch contain a clock which is better than the computers' clocks? Or maybe it's just an abstraction done by the switch on the gPTP packets from both sides?<BR /> <BR /> Also- I try to send Announce messages with higher priority from one of the sides, but the switch seems to ignore them. Any idea why? It does use BMCA, right?<BR /> <BR /> Thanks Thu, 17 Jan 2019 21:16:30 GMT shirArg 2019-01-17T21:16:30Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/gptp-switch-becoming-the-master-of-both-sides/m-p/77290#M19564 Hi, <BR /> I'm using x430-8p switch, connected to two PCs that use the OpenAvnu AVB implementation. <BR /> AVB is enabled in the switch. <BR /> My question is regarding the gPTP protocol- the computer in both sides appear to have the switch itself as a grandmaster. <BR /> Does the switch contain a clock which is better than the computers' clocks?
