Dell 3548P Vlan issue

I have 4 of these in different IDF's in the building, and a stack of 3448P in the MDF.  I have two vlans that need to be available, 120 and 125, 120 for data and 125 for the new VOIP system i'm putting in.  I made the server IP for the voip 10.15.125.254.  on that switch i set the port mode to access and added 125.  on one of the 3548P, i have all the voip switches statically assigned addresses on 125 vlan.  i set those 4 ports to access mode as well and added 125.  the rest of the ports are in general mode so the phones get 125 vlan and then the pc that gets plugged into the phone will get the 120 vlan.  from the 3548, i can ping the server, but i can't ping any of the switches on the 125 vlan, am i configuring the ports wrong?  im attaching the config .

The 3548 doesn't have an IP address on VLAN 125, so it must route via the default-gateway 10.15.120.1.
Can the router ping any of the switches on VLAN 125?

yes it can...im attaching config of the 3448 that has the server configured on port 1/e35 with the port in access mode and it works fine, not sure why the 3548 wouldn't too. thanks for the help, and all these 35's and 34's are connected via fiber on sfp's

You can't ping the 3448 from the 3548 because the 3448 doesn't have a default-gateway.

i can ping from the 3548 to devices on the 3448 though. but i can't ping any devices on the 125 vlan on the 3548, but i can ping a device on the 120 vlan on the 3548

any ideas?

Craig BeckCommented:
You can ping hosts on the 3448 as they will have a default-gateway (unlike the 3448 switches).  You won't be able to ping the 3448 switches from the 3548 as they don't have a default-gateway.  Is it just the switches you can't ping, or hosts connected to the 3448s on VLAN 125?

the switches can ping each other fine,   basically its like this,  i have a MDF that has 2 3448's in a stack, that is connected to another building that holds the router and a 6224F for fiber connections.  the 3448's connect by fiber to a standalone 3548 in a IDF, that 3548 is connected by fiber to another 3548 in another MDF.  The 3448's and the 3548's are all in the same building.  the 3448 has 1 port configured on vlan 125 for the voip server, the one 3548 that is connected to the other has 5 hosts on it, 4 statically assigned addresses on vlan 125 and one statically assigned on vlan 120.  if i plug in a lap top to that switch i get a 120 address like i should, i can ping anything on vlan 120 and i can even ping the server on vlan 125.  but i can't ping any of the hosts on vlan 125 on that same switch.  From the switches, they can all ping each other, and they can all ping anything on vlan 120 and the server on 125, however, they can't ping any of the hosts on vlan 125 connected to the 3548.  Either the switch they are plugged into can't ping them.

Ok, that sounds a bit clearer :-)

Do the hosts on VLAN 125 have gateway addresses?

jasonmichelAuthor Commented:
Yes they do...even if I assign a laptop statically to one of the ports it doesn't work

Can any of the hosts on VLAN 125 ping another host on VLAN 125 on the same switch / on another switch?
0
 
jasonmichelAuthor Commented:
well we only have 5 hosts total, 4 on the 3548 and 1 on the 3448 stack.  the hosts on the 3548 are shoretel switches, so i can't ping from them, but the server on the 3448 can't ping them either.  i can't even ping them from their own 3548 switch console

...penny dropped now I think...

In your question you said...
i have all the voip switches statically assigned addresses on 125 vlan.  i set those 4 ports to access mode

Do you mean that you have connected the switches to these ports?
0
 
jasonmichelAuthor Commented:
yes, i have the voip switches connected to these ports, but i also connected a laptop to them and it didn't work

Craig BeckCommented:
Ok, try setting those ports to trunk ports instead of access ports and try again.

jasonmichelAuthor Commented:
that didn't work,  i did this, i took one of those switches and plugged it into the 3448 stack with the server, configured a port in access mode for vlan 125 and it worked just fine, so theres got to be an issue with one of the two 3548's in the  mix, i am attaching all the configs for the devices in play, and a net diagram.  maybe it will help.

There looks like there's a trunking problem.

Can you ping the server if you connect a laptop to 3548/station2?

yep, actually i figured it out, there was a 6248 that had the fiber connected, it was initially supposed to be the 3448.  points awarded for helping
