4500x in vss mode doesn't reach the default gateway

Hello,

i have two 4500x in vss mode configured as layer 2 switch (with no ip routing).

the same config on a 4500x in standalone mode working well.

i have only one svi and from this I can't reach the default gateway (another 4500x).

 

But if I connect a pc on an access port (same vlan of the svi) of the two 4500x in vss mode reach all the ip of the vlan expect the default gateway.

if I connect the 2 switch to the standalone (that are working) I can ping the ip of the standalone but not vice versa.

To sum up:

2 4500x in vss connected at default gateway: doesn't reach anything 

 

2 4500x connected at layer 2 switch: reach the switch but not the default gateway

 

pc on same vlan of the vss switch: reach the vss switch and everything on vlan but not the default gateway

 

same config on standalone: all work well

 

the links between the switch are a simple trunk without pruning.

 

thanks at all!!
