10.82.0.0 - 10.82.7.255
We have been experiencing broadcast storms, currently being stopped by the switches broadcast-limits. I have been advised to segment the network using vlans to stop the issue.
I have begun setting this up. The current setup
; J4899B Configuration Editor; Created on release #H.10.29
hostname "ProCurve Switch 2650"
snmp-server location "Laptop Room"
web-management management-url "http://10.82.5.40:8040/rnd/device_help"
ip default-gateway 10.82.0.1
ip routing
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-50
ip address 10.82.7.225 255.255.248.0
ip helper-address 10.82.0.2
ip proxy-arp
exit
vlan 2
name "ILA"
ip address 172.16.1.1 255.255.255.0
ip helper-address 10.82.0.2
tagged 17-32
ip proxy-arp
exit
management-vlan 1
spanning-tree
no spanning-tree 49 edge-port
no spanning-tree 50 edge-port
password manager
As a starting point I have tried pinging addresses within management console.
10.82.7.225 replies but 172.16.1.1 produces the message "Network is unreachable on this vlan".
What have I done wrong?
Thanks for any help
Solved! Go to Solution.

Re: Problem setting up a VLAN
The system now responds. No doubt I'll be posting other queries as I go.
Apologies for wasting peoples' time.

Re: Problem setting up a VLAN
172.16.1.3 subnet 255.255.255.0 default gateway 172.16.1.1. This machine cannot ping 172.16.1.1 nor, not suprisingly, anything else.
I'm sure I'm missing something simple.
Thanks for any help

Re: Problem setting up a VLAN
We have a core switch, a 5300. I have now set up the vlan on the edge switch and the core switch and can now ping from the xp machine to both the edge and core switch adresses (172.16.1.2 - edge, 172.16.1.1 - core). I have enabled ip routing on the core switch and tagged one of the server connections. However the server on 10.82.0.2 cannot ping the xp machine on 172.16.1.3. I have set up a static route on the server which enables it to ping 172.16.1.1 successfully. This suggests that the core switch is not actually doing the IP routing.
Once again thanks for any help.

Re: Problem setting up a VLAN
1) setup the required VLANs and assign IP addresses on the switch
2) enable ip routing on the switch
3) configure a default gateway and any necessary static routes on the switch
4) configure each station to use the appropriate vlan ip of the switch as their default gateway
5) tell your router/firewall/whatever connects you to the internet how to reach the new subnets by adding a route back to the switch for those

Re: Problem setting up a VLAN
I don't get to configure the router although I will have to get control or get someone else to set up the routes for general connection. However for this test configuration I have set up a static route on the server so it know that to get to any address on the 172.16.1.x it goes to the core switch's 10.82.x.x address. As a result the server can ping 172.16.1.1 and get a reply. However it gets to no other 172.16.1.x addresses. Using tracert when trying to ping 172.16.1.2 it correctly goes first to the core switch, but then the signal is dropped. As far as I can see this can only be because the core switch is not routing, although it says that this is enabled.
