Hello,   To get the Mac addeess, just remove the 01 off the front:   016c.b749.1645.a2 = 6cb7.4916.45a2   Hope that helps! ... View more

Hello,    You are punting some packets to your CPU for different reasons:   Packets Received by Packet Queue Queue Total 5 sec avg 1 min avg 5 min avg 1 hour avg ---------------------- --------------- --------- --------- --------- ---------- Input ACL fwd(snooping) 12407162 0 0 0 0 Host Learning 1068246303 100 110 89 81 L2 Control 1354360556 129 138 112 104 Input ACL log, unreach 665179 0 0 0 0 L3 Receive 295526372 0 36 26 16 L2 router to CPU, 7 97160121 7 2 2 3     This is probably expected behavior and 45% cpu really isn't that bad depending on scale of your network.  For your SNMP issue, it would be tough to say without more in depth troubleshooting. It might be a connectivity issue in your network and not the 4500 specifically.    I think 3.8.6 is the current recommended version and is a stable code version.   Hope that helps! ... View more

Hello,   From a CPU standpoint, the process that is high is IOSd:   10130 2264298 32258605 0 27.59960 29.30468 29.46875 0 iosd   Can you post the output of "show processes cpu detailed process iosd"  and "show platform cpu packet statistics". However, I do not believe this is the reason SNMP doesn't work as your CPU is pretty stable. Does SNMP work sometimes and not other times or is it always broken? I do see some bad community counters:   422 Unknown community name   However, the counter is pretty low and if it is not increasing, it is probably not your problem either. You might want to validate your SNMP configuration matches. Can you also post the output of "Show redundancy"?   Hope that helps! ... View more

Hello,   A couple things:   1) 3.2.0 is pretty old code at this point (2011), it would probably be worth looking into upgrading your code even if it is not the cause of your high cpu.   2) I see there are multiple  app_printf.sh processes but they are all 0%. Is that the highest process? Can you post the output of "show proc cpu sorted"? You probably only need to post the top 10-15 lines. As you can see from this post, having multiple of these processes is expected:   https://community.cisco.com/t5/switching/high-cpu-utilization-in-cisco-switch-4507/td-p/2563435   You would want to look at your highest process and not the one with the most processes.    3) 45% CPU shouldn't keep SNMP from working. You still have plenty of CPU remaining. Does it burst higher than 45% at times? Can you also post the output of "show proc cpu history" and "show snmp status"?   Hope that helps! ... View more

Hello,   You are already configured for SSO:   The problem I have is Redundancy: BTRBRGBBMT1T2_Stack3#sho red Redundant System Information : ------------------------------        Available system uptime = 20 weeks, 6 days, 23 hours, 38 minutes Switchovers system experienced = 0               Standby failures = 0         Last switchover reason = not known                  Hardware Mode = Duplex     Configured Redundancy Mode = SSO .    <--------------      Operating Redundancy Mode = RPR     Reason: Software version               Maintenance Mode = Disabled                 Communications = Up   The problem is a version mismatch. One switch is running 3.6.5 and the other is running 3.6.6. Once you get them on the same version, you will be able to get to SSO.    Hope that helps! ... View more
