Don’t get your hopes up, I’m not taking sides here. I just wanted to show how the companies differ in basic switch configuration. Now for you who don’t know who Extreme is, they are the purple ones, better known as Extreme Networks. They offer some pretty nice products that compete very well with the likes of Cisco or HP. Feel free to check out their product line at http://www.extremenetworks.com/.
Configuring VLANs:
Extreme - Create 2 VLANs and basic configuration
create vlan data
configure vlan data tag 2
configure vlan data ipaddress 10.0.2.1/24
create vlan voice
configure vlan voice tag 3
configure vlan voice ipaddress 10.0.3.1/24
enable ipforwarding
Cisco - Create 2 VLAN interfaces and basic configuration
vlan dat
vlan 2 name data
vlan 3 name voice
exit
configure terminal
interface vlan 2
ip address 10.0.2.1 255.255.255.0
no shutdown
interface vlan 3
ip address 10.0.3.1 255.255.255.0

How do i enable ipforwarding on a extreme switch with xos 12.0.2.1
try enable ipforwarding vlan 3 –replace the number with the correct vlan or leave vlan # off to enable ip forwarding on all vlan’s. Then do “show vlan” and “show fdb” to review what you have setup.
Hi, thanks for the info. It helps a lot. What does the “enable ipforwarding” actually do. So what happens with it enabled and disabled.
Thanks again.
Think of it as running “ip routing” on a Cisco router. Though it’s a bit more granular on Extreme equipment “per vlan” so if you had VLAN 1-2 with ip forwarding enabled and 3 not, you would effectively have VLAN 3 that could not route beyond the switch network (L2), while VLAN 1-2 could route just fine. To be honest, it’s been 10+ months since I have touched Extreme so I could be a little of in the memory department but in my experience this is it’s effect.
Thanks again. It makes sense. I just started working with extreme after working with cisco for 2 years. A little different but not too bad.
So which is better in your opinion for running voice and data across the same port for an office? Extreme of Cisco? Using and Avaya phone system.
They both will accomplish the same goal. As far as ease of use, I have a lot more key time in front of Cisco Switches than I do Extreme, however, I like the tagged/untagged methodology of Extreme and HP vs. the “Switchport Trunk Allowed VLAN” command on the Cisco switches. It really comes down to price and preference. If I had to choose at this point in time in my life, I would go with Cisco.
Hi,
I happen to come accross this thread which has been really helpful.
I have an Juniper SSG140 with 2 ADSL Ports (Intend to create 2 VPN tunnels use each ADSL line to our Main Office and dedicate 1 tunnel for voice and 1 for Data) and 8 managed ethernet ports.
I have 2 summit 450e 24p and 1 summit 450e 48p switches stacked.
I want to do the following:
1. have the PCs and Laptops (Data Group) access the Data VPN Tunnel.
2. have Avaya phones (Voice Group) access the Voice VPN Tunnel.
3. have 5 APs on a Summit 300-24p switch (this switch acts as the WLAN Controller) to provide guest access and should be allowed to access internet (i.e. deny access to the Data and Voice networks).
I would appreciate if you could help me configure the Extreme stack switches to achieve this above. What would be the best practice to do this and what would need to do on the juniper SSG140 to achieve the overall effect?
Thanx in Advance,
Best Regards,
Ramesh
Hi,
I am Ramesh again. Just to add to the last request of mine.
I wish to configure the Juniper SSG140 to issue DHCP IPs and route accordingly based on tags.
Thanx again,
Cheers,
Ramesh
