All those counters look good. What does the config look like on channel group 6? Do we have different cables we can try with the channel group? See if that makes any difference on the ports going up and down. Were any config changes made during the time stamps in the logs?   Thanks
Hello all,  First post here; so I'm sorry if I am in the wrong thread..  I inherited a bunch of 5548's. I have two 'stacks'; one stack of three(3) devices and another stack of two(2) devices. The three stack is a VM cluster and the two stack is the Network/IDF. On the IDF side I have this: !interface gigabitethernet1/0/43 description "Link to 5548 vmstk" channel-group 6 mode auto!interface gigabitethernet1/0/44 description "Link to 5548 vmstk" channel-group 6 mode auto!interface gigabitethernet1/0/45 description "Link to 5548 vmstk" channel-group 6 mode auto!interface gigabitethernet1/0/46 description "Link to 5548 vmstk" channel-group 6 mode auto!interface gigabitethernet1/0/47 description "Link to 5548 vmstk" channel-group 6 mode auto!interface gigabitethernet1/0/48 description "Link to 5548 vmstk" channel-group 6 mode auto! and in the vmstack I have this: dl5548-vmstk# sh running-config interface gigabitethernet 1/0/47-48interface gigabitethernet1/0/47 description "Link to 5548-stk" channel-group 6 mode auto!interface gigabitethernet1/0/48 description "Link to 5548-stk" channel-group 6 mode auto!dl5548-vmstk# sh running-config interface gigabitethernet 2/0/47-48interface gigabitethernet2/0/47 description "Link to 5548-stk" channel-group 6 mode auto!interface gigabitethernet2/0/48 description "Link to 5548-stk" channel-group 6 mode auto!dl5548-vmstk# sh running-config interface gigabitethernet 3/0/47-48interface gigabitethernet3/0/47 description "Link to 5548-stk" channel-group 6 mode auto!interface gigabitethernet3/0/48 description "Link to 5548-stk" channel-group 6 mode auto! I am looking for validation that this is a valid config..  vmstk gi1/0/47-48 goes to idfstk gi1/0/43-44 vmstk gi2/0/47-48 goes to idfstk gi1/0/45-46 vmstk gi3/0/47-48 goes to idfstk gi1/0/47-48 vmstk[1,2,3] are connected via hdmi stacking cables..   Should I have separate port-channels for each switch?  Is the same port channel on each vmstk switch a problem? Is this an SMLT/IST problem? ([URL] and [URL]  sh interfaces counters port-channel 6 on both devices shows no errors..  Thanks in advance.
