Hello everyone. Sorry for my bad English
I have a 3750 connected to vlan (trunk vlan 111), in which a large broadcast domain 192.168.0.0/16.
Hosts in this vlan ~ 2000, arp cache at peak 1400 MAC-address
L3 interface vlan 111 on PCroutere.
When I stand the L3 interface from PCrouter vlan 111 on Catalyst3750 I have a problem with
the inaccessibility of hosts on the network 192.168.0.0/16 in vlan 111.
I can not ping some hosts. Do not respond to ARP requests.
From PCrouter available ping the whole network
What is my problem?
