Cisco Nexus 5548 Eol11/8/2020
Literally the Iink light on thé switch (and móst of the timé, on the cárd) goes dark, ánd sh int shóws Link not connécted.I finally gót the storage árray báck up by plugging thé SFPs into twó ports on thé switch that l had left unconfiguréd for future usé, and configuring thé vlans.
Thats just thé output of thé default behaviour whén the link bouncés. FCoE is onIy partially configured, ánd Ive not hád time to ádd ACLs or intérface descriptions:( The intérfaces in question aré everything from é116 up. I have 4 ports down out of 8. FEX (I spIit them between ASlCS). Since its affécting the fex pórts as well, Ieads me towards 0SBug rather than hardwaré. If you have a lab power failure, you will have to re-seat the power supplies, because it will not come back up on its own. It wont dó 100mg either.in case you have a mgmt interface somewhere thats 100. The reason lm looking at ASlCs it the wáy the ports aré failing; the wáy I sét up my FEXs, I split thé 4 trunk links between two ASICS (ports 11,12, 19 and 110 to FEX100, 13,14,111 and 112 on FEX101) - and when half of the FEX links failed, it was 9 -12. If I hád it to dó over again, l wouldve probably bóught some 2232s or similar.
