https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11110#M2138 Blackdiamonds 8000 does it support features such as VSS or IRF ? I mean , Blackdiamond 8000 does it stack can be as a single switch ? I read MLAG+VRRP solution but not seem stack structure,VSS,IRF . Is it right ?

Hit less firmware upgrade is not available from any version to any version = in reality upgrade of the "one system" means reboot very often.<BR /> - the Stacking/VSS/IRF feature itself is SPoF = if the process dies you are in trouble. I have seen so many complains from early adopters of buggy implementations in the past on VSS technology<BR /> <BR /> My summary:<BR /> With MLAG and VRRP you have fully redundant network. With network management you can orchestrate more devices with one click = this is even better than one system by CLI<BR /> <BR /> regards<BR /> <BR /> Zdenek<BR /> Tue, 12 Apr 2016 14:41:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11111#M2139 Zdeněk_Pala 2016-04-12T14:41:00Z https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11112#M2140 thank you for your response. But our customer needs two switch bonded as a stack structure. Is it possible or not ? I think, S series switch support this , blackdiamond not supported .Is it right ? <BR /> Tue, 12 Apr 2016 14:58:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11112#M2140 ibrahim_tutuk 2016-04-12T14:58:00Z https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11113#M2141 actually only 800-series, D2-series, BlackDiamond-series, X430 series does NOT support any kind of Stacking/VSB in the form discussed above.<BR /> <BR /> the rest of actual portfolio does support it. Check the VSB or Stacking feature.<BR /> <BR /> It is supported on:<BR /> A/B/C series<BR /> 71xx series<BR /> X440 up to X770 series<BR /> S/K-series<BR /> <BR /> regards<BR /> <BR /> Zdenek Tue, 12 Apr 2016 15:15:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11113#M2141 Zdeněk_Pala 2016-04-12T15:15:00Z https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11114#M2142 thank you very much<BR /> Tue, 12 Apr 2016 15:19:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/blackdiamond-series-vss-or-irf-or/m-p/11114#M2142 ibrahim_tutuk 2016-04-12T15:19:00Z
