ситуация следующего рода
две каталисты 3560G 3560E (cat_106 и cat_107 соответственно) к cat_106 подключен сервак 192.168.100.6 к порту 19, который в свою очередь засунут в vlan 100 (этот влан анонсирован на соседнюю каталисту cat_107)
cat_106#sh run int gi0/19
Building configuration...
Current configuration : 65 bytes
!
interface GigabitEthernet0/19
switchport access vlan 100
end
при попытке пинга на сервак получаем тишину
cat_106#ping 192.168.100.6
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.100.6, timeout is 2 seconds:

Success rate is 0 percent (0/5)
тем временем на cat_107 делаем
cat_107#clear arp-cache
cat_107#ping 192.168.100.6
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.100.6, timeout is 2 seconds:

делаем следующие действия на cat_106

при этом на cat_106 подключены другие сервера подключенные к vlan 100, они видятся нормально и с cat_106 и c cat_107
