C3850 IP interface not reachable

[gaigl]

Hello,

one of our C3850 makes problems:

switching is ok, but the management Interface:

"interface Vlan252
ip address 172.27.252.141 255.255.252.0"

is not reachable.

I'm connected on the console and the IP stack is up (can ping myself), routing ok:

C 172.27.252.0/22 is directly connected, Vlan252
L 172.27.252.141/32 is directly connected, Vlan252

switch#show arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 172.27.252.141 - 2c3e.cf23.78db ARPA Vlan252
Internet 172.27.253.181 0 Incomplete ARPA

trunks are up and running, vtp is ok, but but the interf vlan ip can't get connection to other IP's, so the switch is working but not manageable.

Any Ideas?

usually I would do a reload, but the connected systems are too important,

Karl
