Dears,


I have a Cisco 3750G, in StackWise mode you are doing, my core-network access. I have a potential of 200 users connected, segmented into VLANs. Also, I have three C2960G switches connected by fiber optics. The issue is that a week ago, there was a power outage that affects the heart and a C2960G C3750G. Since then, the network that is in the C2960G can not connect, but beware, it is certain VLAN only. For example, on my network I have the 130 and VLAN network users physically located in the C2960G are connected by VLAN 115, and this has problems. Also, I have a server that goes by another C2960G lost some time that the ping and connectivity.

The way to remedy this, is putting on a VLAN interface "arp timeout 60" and when I do other VLAN with a "clear arp-cache" Is this harmful to improve performance?
As data, I have a server that behaves like this trafficking fileserver 85.0 Mb / s on an interface directly to the C3750G, and originate in another server that is sending information of images "This can also compromise performance?


VLAN configuration if it works


interface Vlan130
  ip address 172.18.X.X 255.255.255.0
  no ip redirects
  no ip proxy-arp
  no ip mroute-cache
  ntp disable
end


VLAN problems ...


interface Vlan115
  ip address 172.18.y.y 255.255.255.0
  no ip mroute-cache
  ntp disable
  arp timeout 60
end


Trunking interface switches C3760G -> C2960G

interface GigabitEthernet1/0/52
  description xxxxxxxxxxxxxxx
  switchport trunk encapsulation dot1q
  switchport trunk allowed vlan 10,100,103-109,111,115,123-126,130,133,160,168
  switchport trunk allowed vlan add 200,300,350,370,375
  switchport mode trunk
  switchport nonegotiate
  storm-control broadcast level 80.00
  storm-control multicast level 80.00
  storm-control unicast level 80.00
  storm-control action trap
end


Best regards,


Sebastián
