Do you have dhcp relay configured on the Voice VLAN?
Does it work if you plug a phone into a port which is untagged on voice vlan only?
It would be worth setting up a mirror to a port, plugging in a phone, and then observing the traffic in a wireshark trace

Yes, the switch needs a default gateway to allow management from other networks.
You can do this with ip route-static 0.0.0.0 0.0.0.0 <next hop ip>

Are the workstations windows?
If they have limited accounts then they cannot modify TCP/IP configuration..so that's one possible solution.

I have a requirement to NAT from 10.0.0.1 to 192.168.0.1. I have a spare Cisco 800 series lying around, which has a built in 4 port switch. The WAN interface is for ADSL, so is not a fast ethernet interface. I am not sure if it's going to be suitable for what I need.
I tried this command:

Have you added exceptions to the SuSE firewall via Yast?
IF SAFE TO DO SO try the command "SuSEfirewall2 stop" and try again
Also is SSH configured to run at the runlevel you are using? Check it out with "rcsshd status" - if it's set to "unused" then to need to set it to autostart with...
Which switches are you using?
I ask because on the 4800G for example there is a feature called vlan security which will I think will accomplish what you are after.
'When all else fails.......read the manual'
Just thought I'd add my 2 cents.
As the 5500-EI is a Layer 3 switch then one of the switches will become the router for inter-vlan traffic. What I do is have IP addresses on VLAN 1 for management on every switch, but only 1 switch has an IP interface for the voice VLAN and this becomes the...
It's quite odd. I wonder if it's a bug?
I tested this:
interface GigabitEthernet1/0/9
port link-type hybrid
port hybrid vlan 1 untagged
port hybrid vlan 7 untagged
And then if I do a look at the interface:
[4800G]dis int gig 1/0/9
GigabitEthernet1/0/9 current state: DOWN
IP Packet Frame...
Ps - I forgot to add, that my present understanding is that an untagged packet just goes onto the native VLAN of the port, as per the ports PVID.
If I set the hybrid port to vlan 1 untagged and vlan 2 untagged, how will it know what to do with traffic on vlan 2?
'When all else fails.......read...
For some reason I was under the impression that on a 5500 switch, only 1 vlan (when in hybrid mode) could be set as untagged.
However I see on the 4800 I can have several VLANs untagged.
When the switch is on it's own (that is, a single stack, no other switches to connect to), what is the...
Hi Blister, thankyou for the detailed response.
The disks are on the same controller, yes. Your point about
making a separate array/logical drive makes perfect sense. Didn't think of that! I have now done that and I can see the 250GB disk.
Fair point about the boot volume. This isn't a...
Hi,
I am trying to configure an ML110 as follows:
1 x 250GB Drive, standalone, OS Disk
2 X 1TB drives, RAID1, Data disk
When I enable the SATA mode to RAID and create a logical disk, that all works OK, but when I try to install the OS, the boot controller is seen as the 1TB array and I am...
You could do it if you have the two domains in separate broadcast domains (so new and old DHCP won't clash)
You could use port based VLANs or even a new/spare switch not connected to the old one with New DC's and PC's attached, and move PC's over.
All down to the scale of the task I suspect...
Are you using roaming profiles? I know that some of my users have problems moving between 32 and 64 bit machines...

Are you logging on to the same DC each time? How many do you have in the domain (or site?) It sounds like you are being warned of a potential man in the middle attack but indeed it may be caused by something else.
When you get the dodgy display have you tried opening up a command prompt and...
Thanks for that chaps, had a feeling that would be the case. Didn't seem logical to me.
Jimbo, these are 3Com switches and operate in a similar manner to what you have described.
'When all else fails.......read the manual'
Based on what the original poster has said, I think changing the network mask to 255.255.254.0 is going to give by far the least headaches.
Also with a mask of 255.255.254.0 you get 510 hosts per subnet...thus 192.168.111.x would not talk to 192.168.222.x without a router so be careful with...
I have a question regarding VLANs and associated layer 3 interfaces.
I have say VLAN10 on a core switch. There are 3 switches connected to this via fibre for edge devices. VLAN10 exists on all switches, and the switch to switch links are set as trunks and allow vlans 1 and 10 (3com switches...
Turns out I missed a command - just in case anybody else has the same issue.
interface Vlan-interface7
ip address 10.1.2.1 255.255.255.0
dhcp select relay
dhcp relay server-select 1
'When all else fails.......read the manual'
On the 5500G setting up DHCP relay was simply a process of setting a dhcp server and then using almost the same command at the VLAN interface level. This doesn't appear to be the case with the 4800G.
I have a single stack with 2 units, currently in use for testing. I have attached one of the...
