Nexis 7k drops on the M1 card are for the ENTIRE asyc

Got a call that there was a spike in output drops on a nexus 7K M1 card. the odd thing was there were 3 port channels with the EXACT same number of drops. looking further there were only 1 port per port channel with drops and again they were all the same. It then occured to me to look at the port to ASIC chart and all 3 ports were using the same ASIC. While we still have a case with cisco, looks like output drops are counted at the ASIC level not the port level. Also seemed like having a running monitor port in that ASIC had a lot do with the drops in the first place. sho int counter error shows the deal -------------------------------------------------------------------------------- Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards -------------------------------------------------------------------------------- mgmt0 0 0 -- -- -- -- Eth1/1 0 0 0 0 0 0 Eth1/2 0 0 0 0 0 11285742206 Eth1/3 0 0 0 0 0 0 Eth1/4 0 0 0 0 0 11285742206 Eth1/5 0 0 0 0 0 0 Eth1/6 0 0 0 0 0 11285742206 Eth1/7 0 0 0 0 0 0 Eth1/8 0 0 0 0 0 11285742206 Eth1/9 0 0 0 0 0 0 also policy maps on the interfaces glic-core-rsw1# sho policy-map int e 1/4 Global statistics status : enabled Ethernet1/4 Service-policy (queuing) input: default-in-policy SNMP Policy Index: 301991953 Class-map (queuing): in-q1 (match-any) queue-limit percent 50 bandwidth percent 80 queue dropped pkts : 0 Class-map (queuing): in-q-default (match-any) queue-limit percent 50 bandwidth percent 20 queue dropped pkts : 565 Service-policy (queuing) output: default-out-policy SNMP Policy Index: 301991962 Class-map (queuing): out-pq1 (match-any) priority level 1 queue-limit percent 16 queue dropped pkts : 0 Class-map (queuing): out-q2 (match-any) queue-limit percent 1 queue dropped pkts : 0 Class-map (queuing): out-q3 (match-any) queue-limit percent 1 queue dropped pkts : 0 Class-map (queuing): out-q-default (match-any) queue-limit percent 82 bandwidth remaining percent 25 queue dropped pkts : 11731496978 glic-core-rsw1#
