Cisco Switching/Routing :: Config Erasing Automatically On C500 And 2960 Switches?
Feb 8, 2012 I have a scenario where 15 c500 switches and 5 2960 8 port switch connected to 4507R core switch. There are 10 dhcp pools created on the 4507.
Eg: ip dhcp pool XXXX
network xxxx.xxxxxxx
default-router x.x.x.x
Now the default router is directed to vlans created on the switch i.e vlan 101, 102, 103 and so on. Now the remaining switches connected are configured to be in the same vlan. So the systems connected to the edge switches will get the DHCP ip automatically, Now my problem is after sometime (may be 2 or 3 hrs) all the edge switches are losing configuration automatically even though it's not restarted, even after saving the config on to nvram, everytime I connect the console and check all the saved config is lost?

Cisco Switching/Routing :: 3950 - High Latency And Packet Drop Towards Access Switches?
Jan 27, 2013My network Infrastructure consists of 2 core switches(cisco 3950, 24 port) and 3 access switches (cisco 2960G, 48port). No distribution layer.Both Core switches are connected to the BVI of a VPN router.PVST is running in all switches. The STP results are all good. We have 3 VLAN's in the LAN an IP routing is enables in the core switch. The network diagram is attached.
The issue we are facing is that , we get intermittent packet drops while pinging towards the access switches, and there is always a higher latency towards these assess switches.These issues are present even with no other users using the LAN. But these issues are not present while pinging towards the GW.
I guess, it is because of this, we have issues the accessing file server in the LAN. How do we go ahead with the troubleshooting. Will upgrading the IOS resolve this.The present version details is..

Cisco Switching/Routing :: 6500 / High Switching Processor Utilization?
Sep 20, 2012I am seeing a strange situation on my 6500 switch?By having snmp walk on '1.3.6.1.4.1.9.9.109.1.1.1.1.3' (== cpmCPUTotal5sec), I came to know that there are two processor and the cpu util for switching processor is gone to 88 % and some time creeps to 99 %.
snmpwalk -v2c -c "removes" sw6500 '1.3.6.1.4.1.9.9.109.1.1.1.1.3'
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.1 = Gauge32: 12 (--- this is for CPU of Router Processor )
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.3 = Gauge32: 99 (--- this is for CPU of Switching Processor )
but when I do sh process cpu on the console, all looks normal as it shows cpu utilization of RP. why the value is so high on the switching processor ?
Cisco Switching/Routing :: Getting Very High CPU In 6509?
Mar 3, 2012I have 2 6509-E chassis with SUP-720-VSS and classic line cards :-(. on October 2011 the switch reached 100% CPU on both devices and the entire network went down. Customer restarted the core so we lost all the log files and couldnt find out any root cause on the same. TAC engineer suggested to have some script configured on the system in case of CPU shooting up above 70%, it will create a file in flash and keep appending the logs to the same. Last week i got call from customer saying that the CPU again went high for around a minute on both the cores. Last time i added CoPP also on the switch in order to prevent the CPU reaching 100%. Still it went high and from the captured logs i saw that the process created the high CPU was Port Manager Per and SSH process. Attached the file created by the netdr capture command.

Jun 8, 2013The fans 1 & 2 in Module 1 on the Nexus5K are still experiencing the very high RPM and speed issue.
I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 1. 7950 to 12500 rpm expected. I have provided the output for both the fan detail and the temperature.

Apr 24, 2013I've been looking at reported problems with our Vdeio Conferencing kit attched to a stack of 3750's (which I think is down to QoS) but this got me looking at the logs. We get a lot of high CPU utilization warnings mainly for SNMP (315), Hulc running con (95), Virtual exec (289). I understand the last two are normal, and the SNMP one is probably Cisco Works polling as it happens every 4 hours.
However I've got an odd one: Apr 25 07:34:58: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 93%/0%, Top 3 processes(Pid/Util): 296/85%, 144/0%, 154/0%
