Layer 3 switch configuration problem

Dear,

I am attaching (nuera gx-1k) unified communication gateway with my Layer 3 switch 3560G and facing a problem

The voice gateway is working fine in VLAN 10, and the gateway is attached in vlan 10

but the gateway's one ip 192.168.10.126 is not accessible from vlan 7 or any other vlan while its other ip 192.168.10.125 is accessible,

Amazingly .125 and .126 both ips are accessible in vlan 10 and the voice gateway is working fine,,

Please review my switch configuration I attached and advise

thanks

Hi,

Can you do a sh ip arp 192.168.10.126 and sh ip arp 192.168.10.125

If it is incomplete for 126 but ok for 125 then clear your arp cache and then retry a ping and let us know.

Regards.

Alain

Dear, the problem has been resolved,

Actually my vendor didn't entered gateway IP address for its one interface .126 in his voice gateway device, as soon he entered it, it is accessible now,

thanks for your support : )
