The task relates to IGMP/MLD Snooping packet processing. Is multicast configured on the network? The new firmware does have some improvements that may help. If you can schedule some time to do the firmware update, it would be worth it.  [URL] If the network is being flooded then the firmware may not help.
Hi everyone, We have a few Powerconnect 8024F using more than 60% of its CPU time on `snoopTask`.  status      bytes------ ----------  free  674521408 alloc  327563488CPU Utilization:  PID      Name                    5 Secs     60 Secs    300 Secs----------------------------------------------------------------- 4ad0a00 tTffsPTask                 0.00%       0.02%       0.00% 4aede50 tNet0                      0.21%       0.08%       0.05% 4d19990 ipnetd                     0.21%       0.03%       0.00% 4d780d0 envMonTask                 0.00%       0.13%       1.18% 4d818a0 osapiTimer                 0.00%       0.11%       0.14% 4f93200 bcmL2X.0                   3.17%       3.44%       3.34% 4fb9ac0 bcmCNTR.0                  0.84%       0.87%       0.84% 500dde0 bcmTX                      2.33%       1.96%       1.76% 56cbd50 bcmRX                      4.87%       4.45%       4.40% 5cbdc90 MAC Send Task              2.75%       3.12%       3.19% 5cc7190 MAC Age Task               1.90%       0.63%       0.67% 6aa3310 bcmLINK.0                  1.27%       0.84%       0.68% 91fa040 tL7Timer0                  0.00%       0.00%       0.01% 921f950 osapiMonTask               0.00%       0.06%       0.07% 9224e70 serialInput                0.00%       0.01%       0.01% a4fb110 portMonTask                0.00%       0.00%       0.01% a5254b0 simPts_task                0.00%       0.03%       0.05% ac294e0 emWeb                      0.00%       0.00%       0.01% ac3c400 dtlTask                    4.44%       4.31%       4.18% ac456d0 dtlAddrTask                0.00%       0.00%       0.01% ac8ebd0 hapiRxTask                 2.33%       1.55%       1.47% ba8b380 DHCP snoop                 0.00%       0.00%       0.02% ceea3a0 dot1s_timer_task           0.84%       0.35%       0.28% da20f40 unitMgrTask                0.00%       0.01%       0.00% dc03030 snoopTask                 66.73%      68.60%      67.56% ed219b0 dhcpsPingTask              0.00%       0.03%       0.03% eeb1d30 ipMapForwardingTask        1.27%       1.21%       1.22%156d8780 ip6MapLocalDataTask        0.21%       0.31%       0.34%15d09730 lldpTask                   0.21%       0.16%       0.16%15fad980 tCptvPrtl                  0.00%       0.05%       0.03%164cba80 isdpTask                   0.00%       0.05%       0.49%16d41400 RMONTask                   0.21%       0.16%       0.19%16d531f0 boxs Req                   0.00%       0.00%       0.01%----------------------------------------------------------------- Total CPU Utilization             93.85%      92.74%      92.57% These switches typically are connect to a dozen 5548s and running rstp in between, purely layer 2, all of them are on firmware 5.1.0.1.  We are quite surprised to see little performance issue given the high load. Are we seeing a firmware bug or something a lot more sinister? What is `snoopTask` and how shall I troubleshoot such problems? Please let me know if any additional info is required, Thank you very much. Will
