Below is an example from the concepts guide<BR /> <BR /> Slot-1 StackA.13 # show stacking stack-ports<BR /> Stack Topology is a Ring<BR /> Slot Port Select Node MAC Address Port State Flags Speed<BR /> ---- ---- ------ ----------------- ----------- ----- -----<BR /> *1 1 Native 00:04:96:26:60:DD Inhibited -- 10G<BR /> *1 2 Native 00:04:96:26:60:DD Operational C- 10G<BR /> 2 1 Native 00:04:96:26:60:EE Operational C- 10G<BR /> 2 2 Native 00:04:96:26:60:EE Operational C- 10G<BR /> 3 1 Native 00:04:96:26:60:FF Operational C- 10G<BR /> 3 2 Native 00:04:96:26:60:FF Inhibited -- 10G<BR /> 1 1 Native 00:04:96:26:60:AA Inhibited -- 10G<BR /> 1 2 Native 00:04:96:26:60:AA Operational C- 10G<BR /> 2 1 Native 00:04:96:26:60:88 Operational C- 10G<BR /> 2 2 Native 00:04:96:26:60:88 Operational C- 10G<BR /> 3 1 Native 00:04:96:26:60:99 Operational C- 10G<BR /> 3 2 Native 00:04:96:26:60:99 Inhibited -- 10G<BR /> <BR /> Also you can get some indication from the LEDs see page 152 of the 21.1 concepts guide. Sorry it would copy over very well.<BR /> <BR /> Let me know if that helps to answer your question.<BR /> <BR /> P<BR /> <BR /> Tue, 26 Jul 2016 18:55:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/how-to-tell-the-speed-of-the-stack-connections-for-summit/m-p/9448#M476 Paul_Russo 2016-07-26T18:55:00Z https://community.extremenetworks.com/t5/extremeswitching-other/how-to-tell-the-speed-of-the-stack-connections-for-summit/m-p/9449#M477 Thanks much, yes indeed<BR /> <BR /> Tue, 26 Jul 2016 18:55:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/how-to-tell-the-speed-of-the-stack-connections-for-summit/m-p/9449#M477 Sarah_Seidl 2016-07-26T18:55:00Z https://community.extremenetworks.com/t5/extremeswitching-other/how-to-tell-the-speed-of-the-stack-connections-for-summit/m-p/9450#M478 Just an additional information:<BR /> <BR /> "The port speed is the unidirectional speed of the port.<BR /> <BR /> Some VIM names include speed ratings which are 4 times the unidirectional stacking port speed. For example, the actual stacking port speed for VIM1-SummitStack512 is 128 Gbps. The 512 Gbps rating for the VIM is the unidirectional rate X 2 (bidirectional) X 2 (ports)."<BR /> Tue, 26 Jul 2016 18:58:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/how-to-tell-the-speed-of-the-stack-connections-for-summit/m-p/9450#M478 Henrique 2016-07-26T18:58:00Z
