Hello,
After upgrading all 2960 switches and 3560 (inter-vlan routing) to latest software version I more problems than I was hopping to fix. It appears that after upgrading configuration was changed on the switches. I manged to clean up most of it. One think left is that I cannot ping one of the VLAN interfaces on the 3560 from any 2960.
3560
interface Vlan2
ip address 192.168.8.2 255.255.255.0
!
interface Vlan3
ip address 192.168.7.1 255.255.255.0
!
interface Vlan4
ip address 192.168.6.1 255.255.255.0
interface Vlan10
ip address 10.1.1.1 255.255.255.224
The 2960 switches have IP addresses on VLAN 10 which is also Native VLAN. So, when I'm logged into 2960 switches and try to ping the VLAN 2 interface or anything on that VLAN I get nothing. It will ping fine to any other VLAN.
Why would that happen?
Thanks!

Is the SVI up?

yes it is. Looks like only one switch now will ping from vlan 10 to 2

Hi Greg,
Do you have L2 Vlan-2 configured in 2960s ?

I do. Here is config from 3560 and 2960. Some settings are not shown. Also last night when everybody left I found that all the switches started working fine. I makes me fell that someone is screwing with network.
Config from one 2960:
version 15.0
no service pad
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption
service sequence-numbers

hostname ASW01

Hey Greg - So now you mean you are able to ping to all Vlan 2 IPs ?
Sounds interesting.. If so, did you see any change in config anywhere ?

Its more interesting than that. Last night I downgraded c3560 to latest version of 12.2. This morning I was able to ping every switch only once. When I tried to ping it second time, I got request timed out. I check arp cache on all switches and it looked fine.

Hi Greg Wrobel,
You have to assign ip address for VLAN 1 of all available L3 & L2 switches..
and enable " ip routing " command on you L3 switch.
For example :
if using 192.168.1.0/24 range of ip for VLAN 1
Assign 192.168.1.1 for L3 switch
192.168.1.10 , 20, 30 , 40.. for L2 switches how you needed..
finally enable " ip routing " on your L3 switch..
coreswitch(config)#ip routing
Please Check and let me know..

you do not have any IP address assigned to vlan 2 on 2960 switch, what ip you are trying to ping from 3560 to 2960 ? moreover, your default route is pointing to 192.168.8.1, where is 192.168.8.1 configured ?
Thanks

So today I cleared config on 3560 and reloaded from file, same thing. everything works except communication between VLAN 2 and VLAN 10 where switches IP addresses are. All started after upgrading to c3560-ipbasek9-tar.150-2.se8. Occasionally I get ping replies for few minutes once I restart switches.

It turned out that version 15 was the problem. Downgraded to version 12 and it works properly.
