L3 Gig switch (hp/Cisco)

Hi,

I have a requirement to route two subnets with gig ethernet.

I was looking at the hp E2615-8-PoE switch which according to the spec sheets has gig and is a layer 3 switch.

Can anybody confirm if the switch can do Layer3 on the gig ports? If not, can it do layer 3 on the Fast Ethernet ports? I have a number of Layer2 switches so I don't really need that many ports, just enough to connect the switches to the 3 subnets... (the hp 8 port would be enough)

I am open to other solutions other than L3 switches.

My budget is about $1000, so anything Cisco seems out of the question.
What I require is the ability to configure 3 IP ranges for three separate VLAN's. Ideally, two of them would be Gig but its not necessary (L3 Fastethernet is good enough, but gig would be nice).

Good morning,

Layer 3 switches are usually the cheapest way to route with a decent number of ports.

The E2615 that you mentioned has 8x 10/100 ports and 2 Gig ports (which can be fiber or copper). It will do layer 3 with whichever ports you need it to - you have to configure VLAN Interfaces (which are the layer 3 interfaces) and attribute the VLANs to the ports that you want on that Layer 3 subnet. (important: this only supports IPv4 Layer 3 static and RIP).

If you are looking for a full 10/100/1000 8 port layer 3 switch HP also has the E2915-8-PoE which has the same features but is all Gig. IF you ever plan on expanding, this might be a better option.

Good luck

In the configuration you describe, your budget should allow you to deploy a Cisco L3 switch at the core.  Here are a couple of options with the part numbers in brackets:

Cisco Catalyst 3560V2-24TS switch (WS-C3560V2-24TS)
This 24 port L3 managed switch is at the top end of your budget.  It gives you 24 10/100 ports and 2 gigabit uplink ports.  The uplink ports are SFP ports, so you will need a transceiver (either fibre or copper) to be able to use these to connect your L2 switches at gigabit speed.

Cisco Catalyst 3560-8PCS switch (WS-C3560-8PC-S) or Catalyst 3560-12PCS (WS-C3560-12PC-S)
These 8 or 12 port 10/100, L3 managed switches are well within budget.  They have a single gigabit uplink port

The first option has 2 gigabit uplink ports, so you could connect two of your segments at gigabit speed.

I hope this points you in the right direction.  All of the switches I have recommended are in the Cisco Catalyst 3560 family and can be viewed on the Cisco website at http://www.cisco.com/en/US/products/hw/switches/ps5528/index.html

The other thing he is wanting to know, is will it router traffic between vlans at wire speed = vlan to vlan @ 100mbit and or vlan to vlan @ 1000mbit.
