L3 switch device not pinging

Unanswered Question
Jul 28th, 2010

All, I have a 3750 stacked switch with 2 or so svi interfaces. Vlan50 and Vlan204.

A device which is hardcoded as switchport access mode is on the 50 vlan. I can ping the device, which has an IP of 10.175.56.15 from its source vlan 50 ip of 10.175.56.1.  When I try and ping 56.15 from another vlan svi say vlan204 10.175.204.254 I get no replies.

I can ping every other device on the 50 vlan from vlan 204 but that one device. The device in question is an NTP server from Spectracom.

Its odd that I can source it from the vlan50 int and receive a reply. This means to me that the NTP server does know how to route to its default GW of 10.175.56.1.

But why wouldnt it be able to be pinged from the 204 vlan?

Any help would be much appreciative.

I can telnet into the NTP server, however I dont have credentials, as the customer doesnt own that box.

I have this problem too.

Forgot to include

     10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks
C       10.106.215.192/29 is directly connected, Vlan300
C       10.175.56.0/24 is directly connected, Vlan50
C       10.106.204.0/24 is directly connected, Vlan204
S*   0.0.0.0/0 [1/0] via 10.106.215.193

Here is the port on the switch for the NTP server

interface FastEthernet2/0/48
description XXXXXX
switchport access vlan 50
switchport mode access

Vlan50                 10.175.56.1     YES NVRAM  up                    up     
Vlan204                10.106.204.254  YES NVRAM  up                    up
