New to VLAN's

Hi Guys

 

I am farely new to VLANs and I am trying to setup a voice VLAN on a few switches (2848-48). I have created the following but i want to make sure that this is done correctly. The last time I worked on VLANs was back in 2009 and was mostly on Cisco.

 

Would this be good to allow only "Voice" to use the interface?

 

name "DEFAULT_VLAN"
forbid 10
untagged 1-9,11-48
ip address 140.x.x.x 255.x.x.x
no untagged 10
ip igmp
exit
vlan 100
name "VoIP_VLAN"
ip address 10.x.x.x 255.x.x.x
tagged 10
voice
exit

 

There is no static routes as per below

 

Internet (IP) Service

IP Routing : Disabled

Default Gateway : 128.x.x.x
Default TTL : 64
Arp Age : 20

VLAN | IP Config IP Address Subnet Mask
------------ + ---------- --------------- ---------------
DEFAULT_VLAN | Manual 128.x.x.x 255.x.x.x
VoIP_VLAN | Manual 10.x.x.x 255.x.x.x

 

I can ping the VLAN IP from a machine on the 128 network if i add a route on the pc but I cannot ping anything after that (the VoIP switch itself)

 

Is there anything i need to do on this?

 

Thanks

Martin

Re: New to VLAN's

Hello.  Are you routing between the 128 & 10 networks?  The PC needs a route to the 10 network and a way to get there.

 

Voice VLAN just adds the VLAN TLV to the LLDP packets generated by the switch.  2848 is pretty old, I don't remember offhand what level of LLDP support it has.
