SF300-24 to 2950 VLAN issue

[jjpski_69]

All,

I am new to whole vlan and there are few things I don’t understand. Everything is working fine on the 2950. I cannot get SF300 on the FE1 or FE2 to be able to ping the server on 192.168.0.50, which it should. It seems nothing on V3 on the SF300 can get to the 2950. FE3 and FE4 work just fine. Not very familiar with CLI so if explained in web would be get but I will take any explanation I can get.

Cisco 2950 – 192.168.100.3

Port 24 is trunk to a SHDSL modem.

FE1 – POS TERM 1 – 192.168.0.8 – V3

FE2 – POS TERM 2 – 192.168.0.9 – V3

FE3 – POS TERM 3 – 192.168.0.10 – V3

FE4 – POS SERVER – 192.168.0.50 –V3 – NIC for internal

FE5 – POS SERVER – 192.168.1.177 –V1 – NIC for External

FE6 – Desk top – 192.168.100.175 –V1

FE7 – Desk top – 192.168.100.176 –V1

Cisco SF300-24 – 192.168.100.6 – Mode Layer 2

GE1 - trunk to 192.168.100.3-untagged

FE1 – POS TERM 4 – 192.168.0.11 – Access PVID3

FE2 – POS TERM 5 – 192.168.0.12 – Access PVID3

FE3 – Desktop – 192.168.100.100 – Access PVID1

FE4 – Desktop – 192.168.100.101 – Access PVID1

If the devices on SF300 ports FE1 and FE2  (VLAN ID 3) can ping each other and the same on the 2950 (FE1,FE2,FE3,FE4)  then the problem is most likely in the trunk between the two switches.

Carefully check the inter-switch ports (i.e. ports on both ends of the uplink connecting the 2950 and SF300) are configured as  trunk ports and are configured to forward all VLANS or at least VLAN 3. 

From your description on SF300 the trunk port is GE1. Your description doesn't identify the corresponding port on the 2950.

Also have a look at the VLAN chapter on the admin guide http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/sf30x_sg30x/administration_guide/Cisco_300Sx_v1_4_AG.pdf

Thanks,

Forgot to configure the Trunk port to forward Vlan3.
