Creating VLANs on a LIVE Network

Darren Dyke — Fri, 11 Mar 2011 22:10:37 GMT

Hello All,

My company has exhausted all our IPs in the current 192.168.123.x Scope. I am currently working on implementing VLANs to resolve this issue.

I have never implemented VLANs on a live network, let alone on HP equipment. If someone can look over my configs and help me fix what needs to be fixed so the implementation can be done seamlessly.

Thank you in advance.

Darren Dyke

Re: Creating VLANs on a LIVE Network

Hi,

I don't understand why each switch have ip address for all vlans ?

If the 2910 is your core switch ?
If yes then only this switch need the ip address, all other should only have vlan configured without ip address.
Only one vlan should be used for management purpose and the switch will have an ip default-gateway.

Bye.

I would like to leave vlan 1 for management... since that ip scheme of 192.168.123.x is what all servers and switches currently use.

So on the 2910 it should look like this:
hostname "West_GB_2910"
module 1 type J9145A

exit
ip default-gateway 192.168.123.254

no untagged 3
exit
vlan 9
name "VLAN9_VOICE"
untagged 3
ip address 10.123.1.253 255.255.255.0
exit

vlan 400
name "East VLAN"
ip address 192.168.124.253 255.255.255.0
ip helper-address 192.168.123.6

exit
