Catalyst 3850 high latency on management ip address

[as00001111]

Hey guys,

there is a problem with all of my cisco 3850 switches.

I made a manual endless ping at all devices and there are often responses of 2000ms.

the normal value is 2ms.

there is the recommended IOS version installed: 03.06.06E

Did anyone else encounter this problem?

Thanks in advance!

Hi

so when you ping a an ip interface on a switch ICMP is not prioritized at all and the results can vary constantly depending on the switch and whats going on in it currently

A real ICMP test should be performed end to end device to device through the switch not pinging an interface on the switch  , pinging ips on the interface will give you varied results as you seen , this can depend on the volume of traffic on the switch,  the cpu , whats being processed etc any of these things can cause your results to be off

I don't think you have an issue with your image I would setup an ip sla as a proper test or ping through the device to get more concrete results , pinging the interface is not going to give you correct results

 - Make sure the management port is configured in it's own vrf as in :

  interface GigabitEthernet0/0
        vrf forwarding Mgmt-vrf
        ip address ip-address-value  netmask-value

   Assuming then, that ip-address-value  , is the one , you will be ping-ing
