Routing vlans on 3com switch 4500

Hi, I have not been able to find the command to routing two vlan on a 4500 switch. I thought it was like on cisco switchs "ip routing", but in 3com does not exist this command.

As you said, there is no "ip routing". All new 3Com switches start routing between vlans when you create the vlan interfaces.
for example:
Vlan 1
Int Vlan 1
ip address 192.168.1.1 255.255.255.0
Vlan 2
Int Vlan 2
ip address 192.168.2.1 255.255.255.0

This would create bosth vlans and vlan interfaces with those addresses. If you add a port to any of those vlans, set the gateway for your PCs to be the .1 address and it will be able to route to the other vlan.
At the end of the setup I would also add a stati route to your real default gateway for internet conectivity and such.

Routing Information Protocol (RIP) v1
Routing Information Protocol (RIP) v2
Open Shortest Path First (OSPF) v2 Routed Access
Open Shortest Path First (OSPF) v3 Routed Access
Enhanced Interior Gateway Routing Protocol (EIGRP) stub
Equal-cost routing
Hot Standby Router Protocol (HSRP)

Hello,

I have not worked with 3Com switches only Cisco, but I thought I would post this as I found it when googling:

multicast routing-enable pim
on the vlan interfaces:

interface Vlan-interfacex
ip address ***.***.***.*** ***.***.***.***
igmp enable
pim dm

Those commands should help you get multicasting to work. notice, Vlan-interfacex means you will have to do it for each Vlan you created. Some switches do not include multicast support in their base models but make you buy additional licenses to enable it. Cisco is like that, not sure about 3Com.

I have a 3com 4500 connected to 2 5500s (A & B), which are the the GWs for the 4500. I issued on the 4500: ip route-static 0.0.0.0 0 192.168.0.254 preference 60 (5500 A) ip route-static 0.0.0.0 0...


From your scenario what i guess is the two 5500's (A&B) are connected to each other also. Thats why the link between B&4500 is remaining down due to STP ( to avoid Network loop).
Please correct me if I am wrong.


What is the status of the link connecting 4500 to 5500 B when 500A is active and when 5500A is down .

If you are running STP i will suggest you to wait for 2 minutes after 5500A goes down and STP will be recalculated and the link connecting to 5500B will become active and then the route will also become active.

Best regards

Hi,
If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

How can configure trunk


not sure about the 3COM side, but on the Cisco side... go to the configure prompt, then the port that you need to trunk (int [interface name and number] and enter)

Once you are in the interface, use the following command:
switchport trunk encap dot1q
switchport mode trunk

Then make sure that the interface is not shut down, connect the switches together and (hopefully) the 3COM will negotiate to trunking... if not you will need to manually configure the 3com.

Hope that this helps!

Here's what you need to do:

First, be sure to assign an ip address(in the proper subnet) to each VLAN.

Second, use the ip helper-address command in the context of each VLAN, the address used should be the address of the DHCP server

Third, Add a scope for each additional VLAN on the DHCP server.

The switch will route the DHCP request to the proper server based on the ip helper-address command parameter and based on the ip address of the VLAN that is passed tot he server, a DHCP address in the proper subnet is automatically configured.

Here is a sample:

ProCurve Switch 3500yl-24G-PWR# configure
ProCurve Switch 3500yl-24G-PWR(config)# vlan 33
ProCurve Switch 3500yl-24G-PWR (vlan-33)#ip address 192.168.33.254/24
ProCurve Switch 3500yl-24G-PWR (vlan-33)# ip helper-address 10.1.2.250

Sending DHCP request across diffrent vlans


Hmm... on your DHCP server, try setting the "default router" IP for each pool to be the VLAN ID on the switch.

scope 172.16.0.0 /24
router 172.16.0.1

scope 10.20.8.0 /22
router 10.20.8.1

I think the DHCP replies aren't going back where they should. I've never done this without a router doing all the DHCP, but it does work and i've done it many times. Your config looks spot on for the switch.

Routing


show ip int brief This will show you the available interfaces and type.If you want to create on Fa0/0 for example the config will be as follows:
On configuration mode type
Interface fa0/0.[vlan Id]
encapsulation isl | dot1q [Vlan id]
Assuming you are using dot1q and terminating vlan 200 The config is as follows
int fa0/0.200
encapsulation dot1q 200
ip address --------

on Gig Port

Int gi0/0.200
encapsulation dot1q 200
ip address

The encapsulation used should match the switch trunk.Default encapsulation is isl on cisco switch.If you are connecting another vendor use dot1q encapsulation.
