I have a cisco 3550 Switch and 2900 through fiber, I have configured 5 vlan on the 2900 and 3550.
on the 2900 I have created a Vlan Interface with the range for the vlan 4,
2900(config)# interface vlan 4
2900(config-if)#ip address 192.168.4.254 255.255.255.0
On the 3550 I have configured a DHCP Server for VLAN 3 and VLAN 4, 192.168.3.0/24 and 192.168.4.0/24
3550(config)# Interface Vlan 3
3550(config-if)# ip address 192.168.30.1 255.255.255.0
3550(config)# Interface Vlan 4
3550(config-if)# ip address 192.168.40.1 255.255.255.0
The Problem is:
When I connect a pc on the Vlan 3 I recive a valid IP address and I can ping the Vlan Interface with the range that belong to the Vlan 4 192.168.4.254 but I can no ping to the other pc on the Vlan 4.
When I connect a pc to the port that belong the vlan 4 I can ping to the Vlan Interface, but I can no ping to the other pc on the same Vlan 4.
From the switch 2900 I can ping to all VLAN Interface on the 3550 switch.
I type show ip route command on the 3550 and all Vlan are connected.
Check the firewall on the machine that you are not able to ping. Disable the windows firewall or other firewall to test
and/or configure them to allow icmp packets.
