Hello,

I'm trying to configure two independent network segments on a T1600G-52TS L2/L3 switch. The first network segment is connected to an Internet Firewall/Router and consists of ports 1,2,13-48, 50-52. Port 1 is connected to the Router. The remaining ports are connected to servers.

The 2nd network segment is used to carry VoIP carrier traffic and consists of ports 3-12 and 49. Port 49 is connected via Single Mode Fiber to our VoIP Carrier's router.

All traffic to/from the carrier is tagged with VLAN ID 1403.

I have configured VLAN 1 for all ports communicating through the Internet Router and VLAN 1403 for ports 3-12, 49, in the VLAN 802.1Q section.

I have excluded ports 3-12, 49 from VLAN 1. And I've set up a separate VLAN 1403 for ports 3-12, 49. Port 49 is a TAGGED port. The others are UNTAGGED. And I've configured ports 3-12, 49 to have PVID 1403 with Port 49 to have Ingress checking ENABLED and only allow TAGGED frames.

In this configuration, I can "Ping" the servers connected to ports 3-12 from each other. However, I cannot "Ping" to the Carrier router connected to port 49. Nor can I "Ping" from Carrier Router to any of my servers. And no traffic appears on Port 49.

Any help you can provide would be appreciated.

Regards,

PManley
